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!
Delicious, filling, very creamy and smooth. In the future, I hope to try this one with other nut butters and nut milks. I will also try adding cinnamon.
Tastes like a dessert. This smoothie is my kids favorite so far.
This was like having a milkshake for breakfast! I used half cold-brew, half almond milk, and substituted cauliflower for some of the banana to cut down on the sugar. I also added about 1/4 avocado for extra creaminess. Yum!
So delicious! It’s a keeper.
Delicious! Sweet and chocolaty; love the addition of cinnamon.
Delicious! Sweet and chocolaty; love the addition of cinnamon.
Delicious!!! I used almond coconut milk and loved the chocolate/peanut combination.
This peanut butter chocolate smoothie was so good! The banana taste was a little too much for me so may cut back on the amount of banana and bump up the peanut butter when I make again. This is a winner!
OMG! OMG! OMG! This might be my new FAVORITE smoothie of the challenge! Right off I decided to omit the cacao powder, as I don’t like chocolate. I thought this might leave the smoothie lacking, BUT this smoothie lacked NOTHING! To compensate for the cacao powder I added an extra tablespoon of peanut butter (creamy honey roasted). I also added collagen, as I’ve been adding that to every smoothie this challenge. And I used unsweetened vanilla oat milk. Together these were a PERFECT flavor combo and the thickness was that of a milkshake! I ate mine as dessert, I enjoyed it so much! It also reminded me of eating peanut butter and banana sandwiches as a kid (yummy)! I literally can’t wait to make this one again!
OMG sooooo good
I used real peanuts instead for staying oilfree..added a pinch of cardamom to compliment the cocoa powder, and sprouted oats with alkaline water ❤️ Delicious @simple_weightlossfoods
It’s a secret dessert
Added some spinach for greens and chia seeds, Hemp hearts and flaxseed. Substituted cashew butter.
Really enjoyed this but I think 2 bananas might have been too much for me.. I could have happily split this into two servings
I am not a big chocolate fan. This one was OK.
I love chocolate and peanut butter so was looking forward to this smoothie. Unfortunately it tasted too much like banana. Maybe I need to freeze them longer but they overpowered all the other flavors. Will try it again maybe with only 1 banana.
I doubled the recipe staying with two bananas. Also used the Orgain chocolate flavored protein powder one light scoop. I found it interesting and will try it with the cocoa powder next time.
Interesting enjoyed it. Another good tasting smoothie.
Oh My Goodness, Yes!! This Smoothie Was So Delicious And Creamy. My Taste Buds Were So Excited . This Satisfied The Chocolate And Peanut Butter Lover In Me . I Enjoyed It So Much I Was Scraping Down The Sides Of The Blender To Get The Remainder . I Will Definitely Make This Again.
It would have been delicious if I hadn’t added too much cocoa powder. (I didn’t have cacao powder.) Better luck next time.
Just like a dessert!!! Very yummy and delicious.
