These Keto Peanut Butter Blondies are just as easy as your favorite brownie or bar recipe but are an exciting choice when you are craving peanut butter or just want something a little bit different.

I’ve been wanting to make a blondie for months. I knew raw cocoa/cacao butter would be an excellent substitute for chocolate in a blondie. It is naturally sugar-free and zero carb and acts similar to chocolate in baking. The flavor is mild so these are more peanut buttery than white chocolatey but they are divine.

This recipe is really easy. If you have a glass mixing bowl you can melt the cocoa butter in it is a one-bowl recipe. Those are my favorite type. If I realized the number of dirty dishes that would accumulate before I started a food blog I may have reconsidered. Thankfully, I love my job, despite the piles of dirty dishes.

What is Cacao Butter?

Cacao Butter is a plant-based natural fat that comes from cacao beans (nature’s chocolate!). Cacao butter is a great addition to smoothies for a fat boost and lends a luscious, aromatic richness when used in baked goods, hot chocolate and other warm drinks. –Navitas Organics

Is Peanut Butter Low Carb?

Yup! Just make sure you are buying one without added sugar. Peanut butter is one of the things I go through phases with. I won’t eat for months and then I can’t get enough. I’ll use it in recipe after recipe, both sweet and savory.

What does Raw Cacao Look Like?

Raw cacao/cocoa butter is normally in odd-shaped chunks. This is how my raw cocoa butter came. I just grabbed a chunk about the size of my 1/4 measuring cup and began chopping.

Instructions
 

  • Preheat oven to 350. Spray the bottom of a 9 x 9 baking dish with cooking spray.
  • With an electric mixer combine the first five ingredients until smooth. Add in the flours, sweetener, and chopped cocoa butter. Spread in the prepared baking dish. Bake for 25 minutes until the center no longer jiggles and the edges are golden.
  • Cool completely and then chill in the refrigerator for at least 2-3 hours before cutting.

Notes

Notes on Sweeteners: 
I use my own blend of xylitol, erythritol, and stevia in my recipes. This is twice as sweet as sugar. It is comparable to Trim Healthy Mama Gentle Sweet and Truvia.
To sub in Swerve or Lakanto Monk Fruit use 1.5 times the amount of sweetener called for. 
 
More concentrated sweeteners do not work in this recipe.

  1. Great Recipe Thank You For Sharing Wonderful Article. Really This recipe is very simple and tasty.5 stars

  2. I soaked a paper towel with the excess cocoa butter laying on top of the cookies . They were very soft afterwards and broke when trying to remove them from the pan. The flavor was great though and I’m hopeful that the recipient will love them too4 stars

  3. I didn’t love it. It sort of felt like it was screaming for chocolate chips. I will eat it all but would not make it again. Sorry. 🙁3 stars

  4. Do you mean cacao butter?? I have cacao butter which looks like what you’re using and when I search cocoa butter on amazon lotion and stuff like that comes up…

    1. Yes, I store all my low carb baked goods in the fridge. They are fine at room temp for short times but for longer it’s best to refrigerate.

  5. I used a spatula to hold it in the pan, poured off the liquid, it was a little over cooked. More like a big cookie. Very good. Would be killer good with a frosting of some kind. I’ll try it again, if there is excess liquid, I’ll pour it off sooner. Max

    1. I do not recommend subbing in Splenda for my sweetener. I do not test my recipes with it and it acts much differently than the sugar alcohols I use.

  6. Does Walmart or Aldi’s carry raw cocoa butter by any chance? I have never bought this before and have no clue where to look!

    1. Hi these look so amazing I ordered all the products to make, not realizing how small the package of monkfruit sweetener would be. Can I do half monkfruit half allucose? Brand new to keto-this will be my 1st dessert. Thanks

      1. You might have bought pure monk fruit extract which measures like pure stevia extract. A tsp equals a cup of Sugar or xylitol or erythritol sweetener . It is a very small package but a lt of sweetening power.

    1. I’m sorry but I don’t have a substitute for that. Unless you can find sugar free white chocolate. That would work but is very hard to find.

  7. I just used a conversion guide and it lists the equivalent to 1/2 cup THM Gentle Sweet in Pyure is 1 1/2 cups? Does that sound right? I want to make these now I’m drooling.

  8. Hi, do you weigh your almond and coconut flours or just measure in solid measuring cups? If using cups, do you press it down or measure like traditional flour?

    1. I think truvia would work but I haven’t tested it. If you use lakanto you willneed 1.5 to 2 times as much.

  9. To be clear on the cocao butter, the 1/4 cup is in addition to the 3 Tbsp melted? Looks great and I cannot wait to try it.
    Cheers,

    1. Yup! The 1/4 chopped is almost like white chocolate chunks. You could leave them out but I recommend using them.

    1. I’ve ordered from Amazon. Any food grade cocoa butter is fine. I just look for a cheap one with good reviews.

  10. These are delicious! Thank you for the recipe!! Just to be sure – how should I store these? Do they need to stay refrigerated? Thank you!5 stars

  11. can’t wait to make these- anything peanut butter is worth trying! and another use for my cocoa butter, too- double bonus 🙂
