Chocolate Banana Protein Smoothie

This Chocolate Banana Protein Smoothie blends chocolate whey protein, Greek yogurt, banana, cocoa powder, cinnamon, and water into a creamy breakfast or snack. Ready in five minutes, each serving provides approximately 39 grams of protein.

Recipe Tips

FAQ
Both work well. Frozen banana creates a thicker, colder smoothie, and fresh banana blends more easily with less liquid.
Start with ½ cup to keep the texture creamy. The banana and Greek yogurt provide thickness, so milk isn’t necessary.
Add water and yogurt before the dry ingredients. Blend until smooth, then check the sides of the blender for pockets of cocoa or whey.
Ripe banana and flavored chocolate whey usually provide enough sweetness. Choose a banana with brown spots for a sweeter result without changing the ingredient list.
Too much cocoa powder or an underripe banana often causes bitterness. Measure the cocoa carefully and choose a banana with brown spots for more sweetness.
Add another teaspoon of cocoa powder and blend again. Taste before adding more, since unsweetened cocoa also increases bitterness.
Whey protein traps air during blending, especially when blended for too long. Stop once the banana is smooth, then let the smoothie settle briefly before drinking.
Yes. Start with frozen banana and reduce the water to ¼ cup. Use a blender with a tamper, adding small amounts of water as needed to keep the mixture moving.
No. Unsweetened cocoa powder adds chocolate flavor without the sugar and powdered milk often found in hot chocolate mix. Use unsweetened cocoa powder for this recipe.
No. Greek yogurt and whey protein both contain dairy. For a dairy-free variation, replace both with dairy-free yogurt and chocolate plant-based protein powder.
