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!
Soooo good! I added 3 dates to the recipe and topped the smoothie with cacao nibs. Delicious treat!
Oh this smoothie was chocolicious! I am definitely making it again.
This was my husband’s favorite smoothie so far; too much banana for me. 5 stars for him 3 for me. It does really stick with you though.
This one is thick and creamy and quite enjoyable. For me, the Lemon Smoothie is still the one to beat!
Don’t you mean peanuts are a legume. They are certainly not a fungus.
Yummy! So creamy and delicious.
Love it!!
I do not like peanut butter cups but absolutely love chocolate covered peanuts. Go figure. Wasn’t super excited about this one as a result. I subbed almond butter because I didn’t have any peanut butter. I only had one banana so I subbed cauliflower for one of the bananas and added 1/2 tsp maple syrup becaue it was intially slightly bitter. I also wanted greens so added spinach. So maybe I made a different smoothie in the end? Dunno, either way, it’s tasty. I’d try it again. The recipe that was emailed for the smoothie challenge did not suggest the option of cinnamon. Pretty sure that would have made it better.
Oh this one will be going into rotation it so yummy, I like the chocolaty taste of it and the filling from the peanut butter!
#Day6 chocolate smoothie. My first chocolate and peanut butter smoothie was sooooo good. I will be adding greens next time.
This was great without cocoa powder.
HOW IS THIS POSSIBLE? This smoothie is amazing. There is no added sugar in it, so how does it taste like a chocolate peanut butter cup? I’m so happy to be learning how to make so many great recipes using only real foods/ingredients and still getting the great flavor. Plus all the extra nutrients is a huge bonus!!!
Love this one!!!
This is one of my favorite smoothies. Just like a Reese’s peanut butter cup❤️
So yummy!! Some of my favorite flavors blended together! It makes for a delicious lunch (or any meal) and perfectly satisfies my craving for something sweet at the same time ❤️
Thank you for a wonderful recipe! YUM! I will definitely make again! I wasn’t home so didn’t have my blender, but made it with a potato masher! :D. I didn’t add cinnamon and used cocoa powder because you didn’t have cacao. I thought 2 bananas was a lot, so I made half a recipe.
Another classic combination. I have stuck to the recipes thus far but couldn’t resist adding a shot of espresso to this smoothie! Heaven in a glass!
Not a huge banana smoothie fan but this was pretty good. Everyday my boys (16 & 11) now ask are you making extra for us too. They love Smoothies and are excited to try something new. They requested protein powder in today’s otherwise we pretty much followed the recipe except used cows milk. This has been requested to be a regular by my 11 yr. old.
I’m not a huge chocolate shake person but I do love the chocolate peanut butter combination. I’m glad I tried it! It was delicious just a little too much chocolate for me.
YUM! Who doesn’t like chocolate goodness! Pure, smooth chocolate.This smoothie is so so good.
Oh my goodness…the best (and I prefer vanilla to chocolate anyday)! I literally wanted to scrape every last drop from the blender so I didn’t waste any. I made a double although my hubby had to get in on this one as he is a chocolate/ peanut butter lover!
