Ingredients for a chocolate peanut butter smoothie laid out on a counter.

Ingredients You’ll Need

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: Delivers rich, nutty flavor and a boost of protein. 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.
  • 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.
  • Ground cinnamon (optional): Adds a warm, subtly spicy flavor that enhances the chocolate and peanut butter combination. Plus, it offers a touch of sweetness without adding extra sugar.

What’s the healthiest peanut butter?

  • Look at the ingredient label and make sure it’s just peanuts (no need for extra oils or sweeteners). You can always make your own nut butter at home in a high-speed blender as well. I don’t recommend using peanut powder, like PB1, since it contains additional sweeteners.

How to Make a Chocolate Peanut Butter Smoothie

  1. Place your frozen ripe banana, cacao powder, peanut butter, and oat milk in a blender.
  2. Combine until smooth and creamy.
  3. Scrape down the sides of the blender if the peanut butter sticks and add extra oat milk if the smoothie is too thick.
  4. Pour into a glass and enjoy and garnish with cinnamon if desired.

Storing Tips

You can store this chocolate smoothie in an airtight container in the fridge for up to 3 days or freeze for up to 3 months. If freezing, pour into ice cube trays and transfer to a freezer safe bag once frozen. When ready to enjoy, thaw in fridge overnight and re-blend to get the best consistency.

Notes

  • Peanut Butter allergy? No problem! Swap in almond butter or sunflower butter instead.
  • Oat milk gives this peanut butter and chocolate shake extra creaminess, yet you can swap it with cashew, almond, coconut, or another non-dairy milk.
  • Use unsweetened cacao or cocoa powder; either works fine! 
  • Using homemade protein powder will give you 10 extra grams of protein, turning this smoothie into a complete meal. 
  • Bananas give this smoothie creaminess + sweetness, yet you can swap it out with avocado + maple syrup, avocado + date or cauliflower + maple syrup.

Common Questions

Is peanut butter bad for you in a smoothie?

Peanut butter can be a nutritious addition to your smoothie! While peanuts are technically a legume and not a nut, they’re packed with protein, healthy fats, and essential nutrients like magnesium, zinc, and vitamin B6. If you’re not allergic, peanut butter may help with managing blood sugar, supporting heart health, and keeping you feeling full longer. Just opt for natural peanut butter with no added sugars or oils for the healthiest option!

Is chocolate and peanut butter healthy?

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!

Can you put cacao powder in a smoothie?

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!

  1. I really liked this one. Peanut butter wasn’t too strong of a flavor. I’m hoping that I can get my toddler to drink it as “chocolate milk”. We shall see!

  2. 5 stars
    I was not expecting to like this one but actually loved it. Not too sweet and decadent.

  3. 5 stars
    A great one when craving a bit of chocolate. I added 1/4 cup of Jen’s Homemade Protein Powder. This was wonderful.

  4. 5 stars
    I’m always looking to add protein so I doubled the pb. It’s got a good peanut taste but I think I could add even more. Yum!!

  5. Yummy peanut butter and chocolatey goodness. Enjoyed this one as an afternoon sweet treat

  6. This smoothie was so delicious! I followed the exact recipe and my husband and 7 year old boy were asking for more!

  7. 3 stars
    Was looking forward to this smoothie as I absolutely love peanut butter. Added in cauliflower and avocado along with the protein mix.

  8. 5 stars
    Delicious, creamy, & cold! The chocolate & cinnamon combo gives it a sweet “Mexican chocolate “ flavor! Used almond milk & a few boosts; multi collagen, protein, flaxseeds, and Chia seeds.

  9. 5 stars
    Another fabulous smoothie. I expected to like this one and I did. Will definitely make it again.

  10. 4 stars
    Subbed the banana for cherries and avocado. Reduced the PB and cinnamon. Worked out well – would make again.

  11. The Chocolate Peanut Butter Smoothie was like a creamy milkshake! Absolutely delicious! I wouldn’t change anything! Almost a guilty pleasure!

  12. This is simply delicious!! You can taste the chocolate and peanut butter! I’ll add some chocolate collagan next time

  13. This is a really nice smoothie, really rich in chocolate. I will reduce the cacao powder next time.

  14. 5 stars
    Well of course this one was super yummy 🙂
    I’ll look forward to this as a dessert treat in the future, especially after my unflavored protein powder arrived.
    I mixed in some fresh mint, which gives it a nice little lift. I also used some almond butter/sweet potato mix that I had in the fridge instead of the peanut butter. (That mix was a failed recipe as a dip from an otherwise favorite Ayurvedic cookbook, but worked fabulously in this recipe.)

  15. 5 stars
    I used carob powder instead of cacao because I’m caffeine sensitive. I also added protein powder. Still tastes like dessert! I use this recipe when everyone else is having ice cream.
