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!
I love this chocolatey tasting smoothie, such a treat! I’m currently at home reading and enjoying some ‘me time’.
Day 6
Always a favorite – even better with homemade protein powder.
Rich, creamy, not too sweet
If you’re like me, chocolate and peanut butter is your weakness!! I looked to Day 6 Chocolate Peanut Butter Smoothie for this reason! What a great Saturday wake-up treat!! Yummy! SGS never disappoints!
Yum!!! This reminds me of a peanut butter cup but in liquid form!! 🙂 We both really loved this smoothie! I removed some of the cocoa powder and substituted with chocolate protein powder! Sooooo good!
DEEE-LISH!!!!!!!
Peanut Butter Chocolate Smoothie was good. I only did 1 banana and added protein and greens
Peanut butter and chocolate perfection. Another one for the rotation.
Mine was different tasting, mild, but I made some substitutions, creamy, delicious
smooth… almond butter and macadamia milk were my substitutions for the first time of trying substitutes. very good!
Oh my goodness! Truly my favorite smoothie so far. I love the creamy texture and the taste is amazing. I’m really enjoying this smoothie challenge.
Such a treat! I will make this again when craving a dessert smoothie:). Similar to a go-to smoothie for me from a SGS smoothies recipe book I love – Simple Monkey
Sooo, this smoothie has made it to the redo list! I TOTALLY forgot to freeze the bananas last night and after tasting it tried to pass it off as a hot chocolate w/peanut butter smoothie . Next time I would use a little less 100% cocoa powder since mine is super bitter. I also used peanut powder instead of peanut butter which I would definitely use regular Almond or Peanut butter next time since this smoothie is already heavy in powder if you add the Simple Green Smoothies protein powder. AND I would DEFINITELY USE FROZEN BANANAS , lol. When I remake it I will def come back and give another review but until then I have to give it a 5 since my prep didn’t follow instructions
Loved this one and look forward to making it again! I did add some water because it was very thick. Treat!
I like it! Creamy, wish I had only used 1 tablespoon of the cacao powder though.
Oh this was good! I used unsweetened vanilla almond milk as I don’t do oats. Peanut butter and chocolate is such a great combination. I will definitely make this again.
Great smoothie for chocolate lovers!
Yum! Can you say dessert.
Chocolate Oh Yeah. What’s not to love about this one! Next time I might try to add a bit of spinach or kale as well!
Love it !
Possibly a little too decadent? I used Guittard cocoa powder and it was delicious. I prefer a green smoothie to start my day.
I was not excited because I do not like peanut butter or bananas, but this somehow turned into my favorite of the week!
A bit too thick but I love the flavour. I’m going to add some more milk and see if it is any better
