Energize your morning with a Chocolate Banana Protein Smoothie - a creamy, plant-based shake filled with cocoa powder, protein powder, peanut butter, and banana.
Packed with chia seeds, this vegan breakfast drink is delicious, wholesome, and ideal as a quick meal or a post-workout boost.
Try my green protein smoothie or strawberry banana protein shake for more simple high-protein smoothies.

Chocolate banana protein smoothie is one of those vegan smoothies I can't live without - especially on busy mornings when I need something quick but satisfying.
I always blend them with plant protein powder to keep them more nourishing, just like I do with my tahini date smoothie, frozen pea protein shake, banana mango protein shake, and peanut butter date smoothie.
This chocolate shake is rich, creamy, and velvety smooth, with the perfect balance of cocoa and peanut butter flavor.
The best part? You'll get a nutrient-dense, high-protein breakfast drink that keeps you energized, satisfied, and ready to take on the day without ever feeling heavy.
It's one of those recipes that feels like a treat, but fuels your body with everything it needs.

🍌Ingredients

- Banana: I used frozen banana for extra creaminess, but a fresh banana works too.
- Peanut butter: You can swap it with any nut butter, or use tahini for a nut-free version.
- Protein powder: I chose chocolate protein powder, though vanilla would be just as delicious.
- Cocoa powder: Use high-quality unsweetened cocoa powder for the best rich chocolate flavor.
- Chia seeds: These help thicken the smoothie, but ground flaxseed makes a great alternative.
- Dairy-free milk: I used homemade almond milk, though soy, coconut, or oatmeal milk all work perfectly.
As always, you can find the full recipe with a list of ingredients with measurements in a printable recipe card at the end of this post.
🔪How To Make Chocolate Banana Protein Smoothie

- Step 1: Combine banana, protein powder, cocoa powder, peanut butter, chia seeds, and plant milk in a high-speed blender.

- Step 2: Blend until smooth and frothy. Pour into a glass and enjoy immediately.

📋Variations
- Strawberry chocolate banana smoothie: Blend in a handful of fresh or frozen strawberries for a sweet, fruity twist.

💡Marinela's Tips
- Use frozen banana: It gives the smoothie a creamy, thick texture without needing ice.
- Adjust sweetness: If you like it sweeter, add a date, a splash of maple syrup, or more ripe banana.
- Adjust thickness: This smoothie is naturally very thick and creamy, so add a little extra plant-based milk while blending if you prefer a thinner, more drinkable texture.

❓Frequently Asked Questions (FAQ's)
