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!
My fav of the bunch!
I enjoyed this smoothie I used cacao nibs instead of powder and it was delicious!
I must confess I did not use peanutbutter but instead NUTZO pumpkin spice 7 nut and seed butter, which is only made w nuts and seeds, but NO peanuts.
I love anything chocolate, , so this was a hit
Delicious smoothie. Used coconut milk and crunchy peanut butter.
i made this as written except my bananas were room temp (it’s winter) and i added 1/2c raw cauliflower. (i also added 1/4t cinnamon because i read some of the postings first today. i think doing so *might* have helped a bit yesterday! ) anyway, i thought it needed something more, but i didn’t want to lose the chocolate peanut butter profile, so i added additional peanut butter, 1/4c peanuts, and vanilla. i’ve made this type of smoothie (something with a chocolate banana base) frequently over the years, so i will make it more along the lines of my usual variations in the future. but i like to try something new… plus i’ll be adding cauliflower to my usuals now!
Candy bar in a smoothie!
This is perhaps my favorite smoothie of the challenge thus far. I used Raw crunchy almond butter and added protein powder and extra hemp seeds to make it for a meal replacement. Also I only used 1 banana (reduce the sugar) and 1 tbsp cacao powder. I did add a little frozen cauliflower for extra creaminess.
Another winner winner!
What’s not to love about anything chocolate! The combination of chocolate, banana and peanut butter was very satisfying. I’ll put this one up there with one of my favorites – Chocolate Cherry smoothie.
Surprisingly I didn’t taste the banana. a little too chocolaty. I added an apple because I need a full 24 oz smoothie on the morning.
Chocolate deliciousness!
Oh, my goodness! This is the best ever! I will not have to ever buy a chocolate protein drink again, because this will be my go to! It will also satisfy my sweet tooth for chocolate!
Healthy desert for breakfast. Got to love that.
It’s very yummy, but a bit too much cinnamon for me. I’ll leave that out next time.
Love all things chocolate peanut butter. I used a heaping TBS of PB powder.
Not my favorite. Too much cocoa powder not enough peanut butter flavor. Next time I’ll do 2 tbsp peanut butter and 1 tsp coca powder instead.
Liked it. I think I prefer the fruit/greens variety better, but I’d eat this again.
Can’t. Do. Banana. So I subbed ice cubes for the frozen texture and a sprinkle of alternative sweetener.
Also went with 1 TB PB2 powder for the peanut butter, dropped the cacao to 1TB as I don’t like a strong chocolate, and added a splash of vanilla extract and a scoop of vanilla pea protein powder for more of a meal. Thanks!
Good… the banana wasn’t too strong…yum
DELISH!!! My 2nd FAV
I love chocolate, and mixed with banana was really good. That didn’t take long to go down, it was that good. That one is going. in the recipe files for sure. Loved it! #Challenge Day 6
