Today, I’m breaking down how to prep my fave high-protein green smoothie cubes and sharing some of my favorite flavor combos that are both nutrient-packed and taste-tested (no yucky recipes here, I promise!). Plus, I’ll give you tips on adding extra nutrition to your smoothies to keep you fueled all day.
Busy mornings? No problem! Smoothie cubes are a game-changer when it comes to nutritious, delicious, and efficient meal prep. Whether you’re a parent juggling little ones, a busy professional, or just looking to simplify your healthy eating routine, this method makes starting your day off right super easy.
What Are Smoothie Cubes?
Smoothie cubes are pre-portioned, frozen ingredients for smoothies. You’ll prep greens, fruits, nut butters, and other ingredients into handy cubes and bag them up with nutritional add-ins. Then, when you’re ready, just blend a few cubes with milk or your liquid of choice for a fast, balanced breakfast or snack. I loved these in my third trimester when I was VERY pregnant and VERY tired.
The Benefits of Smoothie Cubes
- Convenient: Smoothies are ready in seconds—just blend and go!
- Nutritious: You control the ingredients and can pack in plenty of greens, fruits, vitamins/supplements, and superfoods.
- Customizable: From peanut butter banana to mint chocolate, the flavor options are endless.
How to Make Smoothie Cubes
What You’ll Need
- Silicone ice cube trays or molds
- Blender
- Fresh or frozen fruits
- Greens (like spinach or kale)
- Milk or milk alternatives (almond, coconut, oat, etc.)
- Add-ins like nut butter, protein powders, or superfoods

Steps
- Prep Your Ingredients: Wash and chop fruits and greens. I like using frozen fruits to save money, and because they are already ready to go.
- Greens Cubes: You can either stuff the greens into the mold then pour milk over or…Blend up greens (I like the “power greens” mix at Walmart that has spinach and kale) with milk until smooth, then pour into silicone molds and freeze. One full tray of greens cubes uses up an entire large container of greens—a sneaky way to get more veggies in your diet!
- Flavor Cubes: For each flavor (recipes below), prep ingredients, layer them in molds, pour in milk, and freeze.
- Supplements: I like to prep pre-measured portions of protein powder and whatever vitamins or supplements I’m using into little bags and freeze them too.
- Package & Store: Once frozen, pop cubes out of molds and store them in labeled freezer bags.
My Favorite Smoothie Cube Recipes
1. Blueberry Banana Peanut Butter
This creamy classic is a favorite in our house. Packed with healthy fats and fresh fruit, it’s a delicious way to start the day.
- Ingredients:
- Frozen or fresh blueberries
- Banana slices
- Peanut butter
- Milk
- Key Tips: Add peanut butter to the mold first so the milk blends in evenly—it’s a little trick that makes a big difference!
2. Mocha Chocolate
Need a caffeine kick? This smoothie combines coffee and chocolate for an energy-boosting treat.
- Ingredients:
- Espresso powder or Instant Coffee (adjust to your preferred strength)
- Chocolate chips
- Milk
- Why It Works: The bold chocolate and coffee flavor completely hide the taste of greens. If you’re a bit skeptical about green smoothies, give this one a try!
3. Banana Chocolate Peanut Butter
This smoothie tastes like dessert in a cup—think Reese’s Peanut Butter Cups, but healthy!
- Ingredients:
- Banana slices
- Peanut butter
- Chocolate chips
- Milk
- Pro Tip: Use ripe bananas for extra sweetness.
4. Mint Chocolate
For the mint lovers out there, this one’s a refreshing yet indulgent option.
- Ingredients:
- Roughly chopped fresh mint leaves
- Chocolate chips
- Milk
- Heads Up: This flavor is a bit niche, but if you love mint, it’s a must-try.
Adding Extra Nutrition
Smoothie cubes are a great base for adding nutritional extras that support your goals. Here’s what I like to include in separate small baggies for each smoothie portion, which makes them ready whenever you are.
- Protein: Add a serving of your favorite protein powder.
- Sweetener: Coconut sugar is a natural, mild sweetening option.
- Prenatals: If you’re expecting, try adding powdered prenatal vitamins or a digestive enzyme (trust me, fellow moms—you’ll thank me!).
- Other Add-Ins: Collagen, fiber, or amino acids are easy to incorporate when blending.
Simply combine the cubes with these add-ins and your milk or liquid of choice, blend it all together, and enjoy a wholesome smoothie in minutes.
Make Your Mornings Easier
Once your smoothie cubes and nutritional extras are prepped, the hard part is done! Mornings become a breeze—all you need to do is grab a few cubes, toss them in the blender, add your extras, and blend with milk until smooth.
Keeping your freezer stocked with smoothie cubes means you’ll always have a quick, healthy meal ready to go. I even batch-prep soups alongside my smoothies to have balanced lunch and dinner options, too.
Final Thoughts
Smoothie cubes are one of my favorite meal prep hacks. Not only are they quick and easy, but they’re also a fun way to experiment with flavors and ensure you’re getting all the nutrients your body needs.
Whether you’re a busy parent, health enthusiast, or just someone who loves having breakfast ready at the push of a button, smoothie cubes are a must-try.
