In college, my late-night study treat was a chocolate peanut butter cup—I would stash them in the fridge, and I swear they tasted even better chilled. That inspired me to craft this chocolate peanut butter smoothie—it’s like nostalgia in a glass, but with a healthy twist.
- It tastes like dessert. Frozen bananas, cacao, and peanut butter powder blend into a rich, chocolatey treat that feels indulgent without added sugar (or a ton of calories).
- Simple, pantry-friendly ingredients. Everything in this smoothie is easy to keep on hand, making it a go-to when you want something fast and satisfying.
- Filling and energizing. Fiber from the cauliflower and natural carbs from bananas help keep you full and fueled for hours.

Smoothie Ingredients
It’s super easy to make a tasty chocolate smoothie, but making it “good for you” takes a few simple tweaks that I’m excited to share with you today:
- Bananas (frozen): A frozen banana adds a cold creamy texture to your smoothie. Ripe bananas are one of the best natural sweeteners, so you don’t need any refined sugars. Freeze bananas ahead of time so you have them on hand.
- Peanut butter powder: Delivers rich, nutty flavor and a boost of protein while being lower in calories and less messy on the blender than traditional peanut butter. If you want to use peanut butter, look for natural peanut butter with no added sugar or hydrogenated oils. You can swap with any other nut butter you like such as cashew or almond butter.
- Frozen riced cauliflower: Frozen riced cauliflower is one of those sneaky smoothie upgrades that no one sees coming! It blends right in, adding a subtle boost of fiber and nutrients without altering the flavor. Not only does it make your smoothie thicker and creamier, but it also keeps things extra cold.
- Raw cacao powder: Provides a deep chocolate taste with antioxidant benefits. Look for raw cacao powder in the baking aisle or health food section of most grocery stores. I like picking mine up at Trader Joe’s or Thrive Market to save money.
- Oat milk: A creamy, non-dairy milk base that ties all the flavors together. Choose unsweetened oat milk to avoid unnecessary added sugars, and check the label for simple, wholesome ingredients. Make oat milk or choose from the cleanest oat milk brands.
- Vanilla bean powder: Adds a warm flavor that enhances the chocolate and peanut butter combination. Plus, it offers a touch of sweetness without adding extra sugar.
Why I use Powdered Peanut Butter
I’ve updated this smoothie recipe to use peanut butter powder instead of traditional peanut butter, and here’s why: Peanut butter is just plain messy in the blender—sticky, hard to measure, and, let’s be honest, tricky to clean.
Plus, it’s tough to find truly clean versions without added oils or sugars. Peanut butter powder, on the other hand, is a game-changer: they’ve removed the fat, so it’s lower in calories but still packed with that peanut flavor and protein. Just be sure to pick a brand without sneaky sweeteners—I’ve done the homework and this is the one I use in my kitchen.

I wouldn’t say peanut butter is bad for you in a smoothie—it’s a popular, easy-to-find option, and it brings healthy fats and protein. That said, I personally prefer powdered peanut butter. It’s less messy, easier to clean up, and lower in calories—so I get that peanut flavor and protein without the extra oil. It’s all about what works best for you!
Chocolate and peanut butter make a smoothie feel like a treat, but they can also be surprisingly healthy! Raw cacao powder adds antioxidants, and natural peanut butter brings protein and healthy fats. Together, they create a delicious, nutrient-packed blend you can feel good about!
Absolutely! Adding raw cacao powder to your smoothie infuses it with rich chocolate flavor and a boost of antioxidants. Typically, 1-2 tablespoons per serving works well. Since ‘cacao’ is less sweet than ‘cocoa’, consider balancing it with natural sweeteners like ripe bananas or dates. Experimenting with cacao can transform your smoothie into a delicious, nutrient-packed treat!
What a wonderful alternative to the “common store-bought” peanut butter cup. I’ve always loved the combination of chocolate and peanut butter, but can’t eat those anymore. I am really excited for this healthier alternative so I can have that flavor combination back. This was just the right amount of sweet (not too much at all), the right amount of chocolate flavor (not too overpowering) and smooth and creamy. This is my new quick and easy go-to sweet treat!!

Smooth and nothing overpowering.
Just the right amount of chocolate flavour, not bitter, and not too sweet. Liquid enough to not need a spoon.
Doubled the recipe except added 3 dates instead of 2 more bananas.
Love the base as a palette to create! There are a number of directions this recipe can go.
This is a nice treat. Not too sweet, but hits that chocolate craving right where it counts!
Loved this smoothie! Def hit that craving for chocolate but in a healthier way. Will be making on repeat and playing around with ingredients to add
I liked this one but I decided at the last minute to try it with almond butter instead…maybe just needed more? Next time will use peanut butter and see if I like it better. Nice and creamy smoothie though.
Using almond butter instead of peanut butter can definitely change the taste of this one!
Delicious! Tastes like a yummy, chocolate milkshake.
Not much of a chocolate/PB smoothie guy, but drank 2 of these. I added a little honey.
It was good but too much chocolate for me, but I enjoyed it maybe switch peanut butter & cacao measurements
One of my favorite combinations is chocolate and peanut butter…this smoothie was delicious. I will definitely make this again. It was a creamy dessert!
The chocolate peanut butter smoothie was delicious. It was like having a dark chocolate peanut butter cup.
I used oatmilk + an extra ¼ cup, just 1 banana, and about 1 tsp extra peanut butter and added chocolate protein powder to make it a meal replacement, 1 Tbsp hemp hearts for a boost of phosphorus, and 1 Madjool date for additional nutrients. It was really, really good. It is perfect for the chocoholic, which I am. I will definitely keep this in my smoothie rotation.
Yummy!! One of my favorites I used almond butter instead of PB and it was still awesome!
so good and very thick I added a little more oat milk so I could at least drink it through a straw hahaha
thank you
Not a favorite. Chocolate wasn’t the problem. It was those bananas! Strawberries would have been perfect. Haha
My favorite combination, chocolate and peanut butter. It’s my go to for smoothies. I used a clean vegan chocolate protein powder instead of cacao.
Not my favorite smoothie. Perhaps I need to try again and change the peanut butter I was using. Can’t figure out why I didn’t love this combination. Surprised me because I’m a chocolate lover usually.
It was great! Love cacao
I live this one except I use almond butter instead of peanut butter. The cocoa powder makes it even better!
Absolutely delicious!!! Thank you!
