Watermelon Protein Smoothie Cubes: An Easy Freezer Prep Hack

Want a simple way to make smoothies easier, tastier and a little more protein-packed? These Watermelon Protein Smoothie Cubes are a fun make-ahead freezer hack worth keeping on hand!

Fresh watermelon, cottage cheese, protein powder and chia seeds come together in a quick blend, then go into ice cube trays to freeze. Once they’re ready, transfer the cubes to a freezer bag so you have a refreshing, convenient starting point for smoothies, smoothie bowls or even a quick frozen snack.

It’s easy prep that makes your future breakfast or snack routine so much easier. And with watermelon bringing natural sweetness and refreshing hydration to the mix, there’s no need to overcomplicate things.

Why You’ll Love These Watermelon Protein Smoothie Cubes

  • Easy make-ahead prep: Blend, freeze and stash them away for whenever a smoothie craving hits.
  • A protein boost: Cottage cheese and protein powder add satisfying protein to each serving.
  • Naturally refreshing: Watermelon brings sweetness, fluid and a fresh fruit flavor.
  • Versatile: Use the cubes for smoothies, thick smoothie bowls or a quick frozen nibble.
  • Simple ingredients: Just a handful of everyday ingredients and a blender are all you need.

Simple Ingredients, Big Possibilities

You only need four main ingredients to make these freezer-friendly smoothie cubes. That’s it! No complicated ingredient list or special equipment required beyond a blender and ice cube trays.

Watermelon is the star of the show! It’s naturally sweet, refreshing and approximately 92% water, making it a delicious way to add fluids and natural carbohydrates to your day.

Cottage cheese adds creamy texture and protein. Blending it into the mixture gives the cubes a smooth consistency.

Protein powder adds another protein boost. I used vanilla whey protein powder, but use your favorite variety and flavor.

Chia seeds bring a little extra fiber, texture and plant-based nutrition to the mix.

Easy Ways to Use Your Frozen Smoothie Cubes

This is where the freezer prep really pays off. Once the cubes are frozen, transfer them to a labeled freezer bag and keep them handy. It’s an easy way to have a head start on a nutritious breakfast or snack without pulling out all the ingredients and starting from scratch every time.

Blend a quick smoothie: Add a handful of cubes to a blender with your favorite milk or milk alternative. Blend until smooth, adding more liquid as needed to reach your preferred consistency.

Make a thick smoothie bowl: Use less liquid and blend until thick and spoonable. Add your favorite toppings like fresh watermelon, chia seeds, chopped pistachios or granola.

Enjoy a frozen bite: Grab an individual cube straight from the freezer for a little refreshing snack.

Watermelon Protein Smoothie Cubes Nutrition

Each 8-cube serving provides approximately 138 calories, 16.1g protein, 12.5g carbohydrates and 2.7g fat. That’s about 17 calories and 2g protein per cube.

Nutrition will vary depending on the protein powder and cottage cheese you choose.

Whether you’re looking for a quick breakfast shortcut, a refreshing snack or a simple way to work more watermelon into your routine, these smoothie cubes are a delicious little freezer staple. Make a batch and you’ll be glad you did!

Watermelon for Active Agers: A Refreshing Way to Support Strength, Recovery & Healthy Aging

This post is sponsored by National Watermelon Promotion Board. Learn more about watermelon nutrition and get recipes at Watermelon.org.

When most people think of watermelon, they think of backyard barbecues, pool days, and summer picnics. But this juicy fruit deserves a place in your kitchen for more than just its refreshing, sweet taste. If you’re like me, and committed to staying active, maintaining muscle, and aging strong, watermelon offers a surprising combination of hydration, nutrients, and plant compounds that can help support those goals.

While no single food is a magic cure-all, watermelon does fit beautifully into an overall eating pattern that promotes healthy aging—and it’s one of the easiest (and tastiest) ways to nourish your body ALL year (Even off season, personal-sized watermelons and produce cuts are almost always available). Add watermelon to a menu rich in protein, veggies and whole grain; add in lots of activity and quality sleep, and you’ve got a recipe for aging with strength!

Helps You Stay Hydrated:

Hydration becomes increasingly important and often more challenging as we age. Our natural thirst response tends to diminish over time, making it easier to become mildly dehydrated without even realizing! For active adults who enjoy walking, running, hiking, cycling, pickleball, golf, or strength training outdoors, staying ahead of dehydration is essential.

Because watermelon is made up of about 92% water, it provides both fluids and naturally occurring electrolytes (310mg potassium, 6%DV and 24mg magnesium, 6%DV), making it a refreshing way to contribute to your daily hydration needs. 

And, remember… proper hydration, from all sources, supports:

  • Healthy circulation
  • Temperature regulation during exercise
  • Joint lubrication
  • Cognitive function
  • Energy levels and exercise performance
Make Watermelon-AID, a homemade sports drink featuring watermelon juice that Watermelon-AID is a homemade watermelon sports drink that will help keep you hydrated, cramp-free and provide energy for endurance events. Easy, effective and economical.
Pro tip: watermelon juice is amazing too!

Supports Heart Health:

Heart health becomes even more important as we age. And, yes, even for women! In particular, after menopause, a female’s estrogen drops and cardiovascular risk naturally increases.   

But watermelon can be part of a heart-healthy diet. It’s totally fat-free, and contributes several nutrients associated with cardiovascular wellness, including potassium (6%DV), vitamin C (25%DV), lycopene (12.7 grams of lycopene per 2 cup serving), and l-citrulline (286-1266mg per 2 cup serving). Together, these nutrients help support healthy blood vessel function and normal blood pressure as part of an overall balanced diet and active lifestyle.¹

Also, it’s of interest to note that low fruit intake is one of three dietary factors associated with death from cardiovascular disease (CVD) and type 2 diabetes (T2DM) (the other two dietary factors are high salt intake and low whole-grain intake).  (Watermelon Board)

Healthy Blood Flow:

One of watermelon’s most unique nutritional benefits is its naturally occurring L-citrulline, an amino acid that the body converts into arginine, which is then used to produce nitric oxide.

What’s so cool about this for us active agers? Well, nitric oxide helps relax blood vessels, promoting healthy circulation. Better blood flow means oxygen and nutrients can be delivered more efficiently throughout the body, including to working muscles during exercise.

Emerging research suggests this may have benefits for cardiovascular health. A 2025 meta-analysis of randomized controlled trials found that L-citrulline supplementation and watermelon intake significantly reduced both systolic and diastolic blood pressure in middle-aged and older adults, supporting watermelon as part of an overall heart-healthy dietary pattern.¹

Rich in Lycopene

Watermelon’s vibrant red color isn’t just beautiful. It comes from lycopene, a powerful antioxidant. Everyday life and especially exercise, creates oxidative stress within the body. While this is a normal process, excessive oxidative stress over time is associated with aging and chronic disease. Lycopene and the other antioxidants in watermelon may help neutralize free radicals and support your body’s natural defense systems. Diets rich in lycopene have been associated with improved cardiovascular health and reduced markers of oxidative stress.²

Helps You Refuel After Exercise:

After a workout, replenishing energy stores and repairing muscle tissue, are your body’s two priorities. Watermelon naturally provides carbohydrates that help replenish glycogen, the stored form of energy your muscles rely on and use up during intense/prolonged exercise.

To maximize recovery, I like to pair watermelon with a quality source of protein, such as cottage cheese, Greek yogurt, chicken, lean beef, my favorite fish, or even with protein powder in a smoothie (like my Watermelon Beet Smoothie). Also, check out the huge collection of recipes at Watermelon.org.

Supports Healthy Skin and Connective Tissue:

Caring for and supporting the tissues that keep us moving is another essential of healthy aging. Watermelon provides vitamin C (25% of DRV), an essential nutrient needed to produce collagen, the protein that helps maintain healthy skin, cartilage, blood vessels, tendons, and ligaments. Combined with its high water content, watermelon can help support and hydrate skin health from the inside out while contributing nutrients important for connective tissue.

Naturally Sweet Way to Satisfy Cravings:

If you’re trying to make more nutrient-dense choices without giving up dessert, watermelon is an easy win. Its natural sweetness, high water content, and satisfying volume make it a refreshing alternative to many calorie-dense treats. It comes in at only 80 calories per 2-cup serving. Rather than feeling deprived, you can enjoy something sweet while also getting hydration, vitamins, antioxidants, and beneficial plant compounds.

Irresistible Nectarine Avocado Caprese Salad (A Fresh Summer Twist!)

If summer had an official salad with my name on it, this this Nectarine Avocado Caprese Salad might just be it! Taking everything I love about a traditional Caprese and gives it a fresh, fruit-forward makeover. Sweet, juicy nectarines step in for tomatoes while creamy avocado, fresh mozzarella pearls, crisp red onion, and cool mint create layers of flavor and texture in every bite.

Finished with fragrant mint and a drizzle of rich balsamic syrup, it’s a light yet satisfying dish that’s elegant enough for entertaining but simple enough for an everyday lunch. The combination of sweet fruit, creamy cheese, and tangy balsamic creates the perfect balance of flavors that feels both refreshing and a little indulgent.

Even better? There’s no cooking required, making it one of those recipes you’ll reach for all summer long when it’s too hot to turn on the stove.

Why You’ll Love This Nectarine Caprese Salad

  • No cooking required. Perfect for hot summer days when you want something fresh without heating up the kitchen.
  • Ready in minutes. Just chop, assemble, and serve.
  • Naturally colorful and beautiful. It’s almost too pretty to eat—and always disappears fast.
  • Perfect for entertaining. Great for backyard BBQs, potlucks, brunches, showers, or weeknight dinners.
  • Meal prep friendly. Assemble everything ahead of time, then add the avocado and balsamic drizzle just before serving for the freshest presentation.

A Fresh Take on Traditional Caprese

Classic Caprese is all about ripe tomatoes, basil, fresh mozzarella, olive oil, and balsamic. This version keeps the spirit of that iconic Italian salad while celebrating one of summer’s best fruits – nectarines and avocado (yes, it’s a fruit!). Juicy nectarines provide a naturally sweet, slightly tangy bite that pairs beautifully with creamy mozzarella. Instead of relying on basil, fresh mint adds an unexpected burst of coolness that complements the fruit especially well.  It’s familiar enough to satisfy Caprese lovers while feeling entirely new.

Can I use Peaches Instead of Nectarines?

Yes, peaches make a natural substitution. In fact, did you know that nectarines and peaches are the exact same species (Prunus persica). The only difference between the two genetically is a  a single recessive gene variant prevents nectarines from growing the fuzzy skin that peaches are known for. And, to be honest – I prefer that! Smooth skin means there’s no peeling is required, and I find them to have a tangier, slightly bolder flavor than peaches.

Both are naturally sweet and provide vitamin C, fiber, potassium, and antioxidants. Choosing ripe—but still slightly firm—nectarines or peaches helps the salad maintain its texture even if it’s prepared ahead of time.

Creamy Avocado Makes It Extra Satisfying

Avocado adds more than just beautiful color. The buttery texture contrasts perfectly juicy fruit while contributing heart-healthy monounsaturated fats that help make this salad surprisingly filling. Combined with protein-rich mozzarella and savory prosciutto, the salad easily works as a light lunch or a substantial side dish. Just wait to add the avocado until serving time to keep it looking vibrant and fresh.

Tips for the Best Nectarine or Peach Caprese Salad

  • Choose nectarines or peaches that are ripe but still slightly firm.
  • Add avocado just before serving to prevent browning.
  • Wait until the last minute to drizzle with balsamic syrup for the freshest appearance.
  • Fresh mozzarella pearls make serving easy, but torn fresh mozzarella (or chopped) works beautifully too.
  • Don’t skip the fresh mint—it gives this version its unique, refreshing flavor.

Recipe Notes

Watermelon and Cinnamon: Surprising Health Benefits + Easy Recipes

Watermelon seasoned with cinnamon and vanilla

Watermelon with cinnamon might sound a little unexpected… but nutritionally, this pairing actually makes a lot of sense. Whether you’re looking for a refreshing snack, a smarter way to satisfy a sweet tooth, or a simple performance-friendly bite, this combo delivers more than just flavor.

Let’s break down why it works 👇

🍉 Hydration + Blood Sugar Balance:  Watermelon is about 90% water, making it one of the most hydrating fruits you can eat—especially helpful before or after workouts, during hot weather, or anytime you need a refresh.

Because it’s naturally sweet, watermelon can spike blood sugar quickly on its own. That’s where cinnamon comes in. Cinnamon has been studied for its ability to help improve insulin sensitivity, which may support a more balanced blood sugar response when paired with fruit.

🔥 Metabolism + Flavor Boost: Cinnamon contains compounds like cinnamaldehyde, which may help support metabolic function. While it’s not a magic bullet, adding cinnamon is an easy, natural way to enhance your overall nutrition strategy.

Bonus: cinnamon amplifies sweetness without adding sugar—so your watermelon tastes even better with zero extra calories.

🛡️ Antioxidant Power Combo: This pairing brings together two antioxidant-rich foods:

  • Watermelon is packed with lycopene, which is linked to heart health and reduced inflammation
  • Cinnamon provides polyphenols that help combat oxidative stress

Together, they can help support recovery from workouts and protect against everyday wear and tear on the body.

🌿 Digestive Support: Cinnamon has traditionally been used to support digestion and may help reduce bloating or discomfort that some people experience with fruit. Adding a light sprinkle can make watermelon easier on your stomach—especially if you’re sensitive to high-water or high-sugar fruits.

💪 A Workout-Friendly Snack: Simple, effective, and easy to digest plus, it’s hydrating, light on the stomach, and naturally energizing. This combo works well pre-workout for quick fuel or post-workout to rehydrate and replenish.

✨ Why I Use Ceylon Cinnamon Instead of Regular

Not all cinnamon is created equal. Most grocery store cinnamon is Cassia cinnamon, which contains higher levels of coumarin—a compound that isn’t ideal in larger amounts over time.

Ceylon cinnamon (often called “true cinnamon”) is my go-to because it’s:

✔️ Lower in coumarin
✔️ Milder and slightly sweeter in flavor
✔️ Better suited for regular, everyday use

If you’re using cinnamon frequently, upgrading to Ceylon Cinnamon is a small change that can make a difference.
