Chocolate, peanut butter, and bananas come together in this creamy, nutrient-packed peanut butter smoothie! This recipe is ready in just 5 minutes using 5 basic ingredients.

I’m not usually a fan of bananas, but combine them with chocolate and peanut butter and you’re in for a treat! If you’re hesitant about bananas in smoothies or love them deeply, this recipe is for you.
Recipe features
- Dietary: vegetarian, gluten-free, optional vegan and optional soy (just use vegan yogurt and soy-free milk)
- Sweet and creamy like a milkshake but healthy enough for breakfast
- Make it mocha-style by adding iced coffee!
What will you need

- Milk of your choice: I usually go for soy milk to make it a vegan/dairy-free smoothie, but any milk works well here. You can choose unsweetened and unflavored to limit added sugars.
- Cocoa powder: This is the same unsweetened cocoa powder you use to bake chocolate chip cookies.
- Banana: The riper it is, the better! I usually cut and freeze my banana for a colder, creamier smoothie. If you skip this step I recommend adding 1-2 ice cubes.
- Flax seed: Ground flax adds fiber and healthy fats. You can omit it or replace it with equal amounts of hemp hearts or chia seeds for similar benefits.
- Coffee: This is 100% optional but I Love adding coffee to give this a mocha twist! I usually make extra coffee in the morning or the day before, then chill it in the fridge for the next day.
- Peanut butter: I use creamy natural peanut butter for a super smooth texture.
Suggestions and variations
- Sweetener: If your banana is not very ripe, the smoothie may not be sweet enough. You can add liquid sweetener such as maple syrup or agave syrup 1-2 teaspoons at a time.
- Protein: To increase the protein in this recipe, add a scoop of your favorite protein powder or a tablespoon of hemp hearts. You can also double the peanut butter.
- Different nut butters: Try almond or cashew butter for a twist on this recipe. Sunflower seed butter is a great option for allergy sufferers.
- Toppings: I love adding chopped walnuts or pecans and granola. Coconut flakes, hemp hearts and raspberries or strawberries are also delicious options.
- Extra fruit/vegetables: A handful of spinach mixes well and is almost imperceptible. Add a touch of fruit with 1 cup of frozen raspberries or strawberries.

Recipe FAQ
Decidedly! You can even quadruple that if your blender is big enough.
Yes, this will make the smoothie even creamier. You may need to add more milk to thin it out.
For best quality, I recommend making this Chocolate Peanut Butter Smoothie no more than 24 hours in advance because it will thin while it’s in the fridge. You can also freeze all ingredients together, except the peanut butter and milk, for easy meal prep.
Yes, but adding melted chocolate can warm up the smoothie a bit. You’ll only need about 1/2 ounce of baking chocolate or regular chocolate.

Instructions

Combine the frozen banana, milk, peanut butter, cocoa powder and ground flaxseed in a blender. Blend until smooth and creamy.

Notes
- Banana: I like to use frozen banana because it makes the smoothie creamier and colder. Cut into slices and freeze on a cutting board for 2-3 hours. You can use an unfrozen banana as well, just mix in 1-2 ice cubes as needed to chill the smoothie.
- Mocha option: I like to make ½ cup of milk and ½ cup of coffee to make a mocha smoothie. Make sure the coffee is cold before adding it to the blender.
- Sweetener: If your banana is not very ripe, the smoothie may not be sweet enough. You can add liquid sweetener such as maple syrup or agave syrup 1-2 teaspoons at a time.
