Chocolate, peanut butter, and bananas combine in this creamy and nutrient-packed chocolate peanut butter smoothie! This recipe is ready in just 5 minutes using 5 staple 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
- Diet-friendly: vegetarian, gluten-free, vegan-optional and soy-free optional (just use vegan yogurt and soy-free milk)
- Sweet & creamy like a milkshake but healthy enough for breakfast
- Make it mocha by adding chilled coffee!
What you'll need
- Milk of choice: I usually go for soy milk to make this 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 that you use for baking chocolate cookies.
- Banana: The riper, the better! I usually slice and freeze my banana for a colder, creamier smoothie. If you skip this step I recommend adding 1-2 ice cubes.
- Flaxseed: Ground flax adds fiber and healthy fats. You can omit this 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.
Tips and variations
- Sweetener: If your banana isn't very ripe the smoothie may not be sweet enough. You can add liquid sweetener like 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 butter: Try almond or cashew butter for a twist on this recipe. Sunflower seed butter is a great allergy-friendly option.
- Toppings: I love adding chopped walnuts or pecans and granola. Coconut flakes, hemp hearts, and raspberries or strawberries are also delicious options.
- Extra fruit/veggies: A handful of spinach blends in well and is nearly unnoticeable. Add a fruit twist with 1 cup of frozen raspberries or strawberries.

Recipe FAQ
Definitely! You can even quadruple it if your blender is big enough.
Yes, this will make the smoothie extra creamy. You may need to add extra milk to thin it.
For best quality, I recommend making this chocolate peanut butter smoothie no more than 24 hours in advance because it will thin as it sits in the fridge. You can also freeze all ingredients together, except for the peanut butter and milk, for easy meal prep.
Yes, but adding melted chocolate may warm up your smoothie a little bit. You will only need ~½ ounce of baking chocolate or regular chocolate.

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

We really enjoyed this Chocolate Smoothie with the kick of coffee. The flavour was so delicious with the peanut butter, Cacao, banana, flax meal and I used unsweetened soy milk on hand. Would be interested in knowing what plant based milk you used Cassidy.
Now onto dinner...making your “dump & bake pasta...Penne Bake” tonight. Thank you for your recipes to try.

I usually go for Silk unsweetened soy milk but lately we have been drinking a lot of Califia Farms oat milk. It is so creamy! Glad you liked this one.
