Peanut Butter Brownies

When it comes to keto recipes using peanut butter, my favorite things to make are peanut butter cookies, peanut butter cheesecake, and these peanut butter brownies.

Since going keto, one of my most used ingredients has been peanut butter. This works very well for me, because peanut butter is one of my all time favorite foods. I enjoy it at least once a day, mostly with my breakfast or in a smoothie in the afternoon. Recently, I’ve been using it in more and more of my desserts.

Peanut butter works beautifully in any kind of dessert. It’s great to use in cookies, in no bake desserts, and of course, in classic dishes like puddings and even a mousse. My favorite use of peanut butter though is spread onto some low carb brownies!

I’ve been meaning to share a peanut butter brownie recipe for quite some time. It’s perfect for those who love the chocolate and peanut butter combination, and it takes no time to prepare! Now, these brownies may look incredibly fancy but I promise you, they are so easy to make!

No sugar and no grains are needed, but you’d never tell. The texture of the brownies is super thick and fudgy, and the peanut butter and chocolate layers are super creamy. They are rich and full of chocolate and peanut butter flavor, without being overpowering. 

I had some friends over for dinner the other night and served them these brownies for dessert and NO ONE believed me when I told them they were keto- They thought these were loaded with sugar and flour!

How do you make keto peanut butter brownies

The Ingredients

  • Almond flourBlanched or superfine almond flour, not almond meal. 
  • Baking powder– Gives the brownies some stability and structure. 
  • Cocoa powder– 100% unsweetened cocoa powder that has been sifted. 
  • Granulated sweetener of choice– I used allulose, but erythritol or monk fruit sweetener can be used. 
  • Butter-Unsalted butter. You can use dairy free if you prefer. 
  • Chocolate chips– Either store bought or homemade sugar free chocolate chips.
  • Eggs– Room temperature eggs. 
  • Peanut butter– Smooth and creamy peanut butter, so it can be easily spread over the brownies. If you enjoy the sweet and salty combination, use slightly salted peanut butter. 
  • Chocolate frosting– For an extra dose of chocolate. 

The Instructions

Start by mixing together your dry ingredients until combined and set aside. In a microwave safe bowl or stovetop, add your butter and half the chocolate chips. Heat together until melted and smooth. Next, add the eggs into a mixing bowl and and beat until frothy and combined. Slowly add the melted chocolate/butter mixture until combined. Gently add the dry ingredients and mix well, until combined. Fold through the remaining chocolate chips.  

Now, transfer the brownie batter into a greased 8 x 8-inch pan. Bake at 180C/350F for 15-18 minutes, or until a skewer comes out mostly clean. Remove the brownies from the oven and let cool for 10 minutes, before spreading the peanut butter on top. Once cool, refrigerate for 30 minutes, for the peanut butter to firm up. Finally, spread the chocolate frosting on top and refrigerate for a further 30 minutes, until set.

Tips to make the best low carb peanut butter brownies

  • You must let your brownies cool before adding the peanut butter and chocolate frosting layers. 
  • Feel free to switch out the keto chocolate chips for a sugar free chocolate bar. Your brownies will be even fudgier because of it.
  • If you have a peanut allergy, feel free to use almond butter or a nut-free alternative, like tahini. 

Storing and freezing peanut butter brownies

    1. What chocolate frosting can be used in a keto recipe like this? Everything I see at the store is loaded with sugar.

      Thanks for the amazing recipe!!

      1. Hi Andrew! Make your own easily using a can of full fat coconut milk heated up, then fold through sugar free chocolate chips or a chocolate bar into it and whisk until smooth. Let it cool slightly, before frosting 🙂

    2. 5 stars
      I can’t believe how good these brownies are! I’ve made some of your cookie recipes and found them wanting (salt remedied this) and worried these brownies might turn out the same. But whether it was the salt in the butter or peanut butter or both, the results were not just good but decadent! Definitely a keeper! And so filling
