These peanut butter brownies are a chocolate & peanut butter lover’s dream dessert. A rich, chocolatey, fudgy homemade brownie base is stuffed and topped with peanut butter cups.
Preheat oven to 350 degrees F, line a 9x9” baking dish with parchment paper and lightly grease, set aside.
Make the Brownie Batter
Mix flour, cocoa powder and sea salt together in a small bowl; set aside.
Melt chocolate and butter together in a microwave safe bowl, or on the stovetop over low heat. Stir until smooth and glossy. Set aside.
In the bowl of a standing mixer, beat eggs for 1 minute or until pale and thick.
Add sugar and beat for an additional 1 minute, until sugar is dissolved, and mixture is thick.
Stir in the melted chocolate/butter mixture and vanilla on low speed until the batter is smooth.
Add dry ingredients, mix on low speed until just incorporated and there are no lumps.
Assemble
Evenly spread ⅔ of the batter into the prepared pan.
Then, add a layer of 12 peanut butter cups (see photos)
Gently spread the remaining batter over the peanut butter cups.
Chop 4-6 peanut butter cups for into large pieces
Gently press into the top of the brownies.
Bake & Cool
Bake in the preheated oven until the top is set and the brownies are only very slightly “jiggly”, 25-30 minutes.**
Remove from oven, and immediately sprinkle the top of the brownies with flaky sea salt.
Place the brownie pan on a wire cooling rack to cool completely.
Cut into squares and serve.

Ingredient Notes/Substitutions
All-purpose flour. For a gluten-free version, substitute a 1:1 gluten-free all purpose flour blend.
Sea Salt. I recommend using fine sea salt. If you use iodized table salt decrease the amount of salt by half.
Semisweet chocolate. Use chocolate chips, chopped bars, discs, etc. the form doesn't matter because it's being melted.
Salted butter. Unsalted butter, coconut oil and gee all work well in this recipe.
Granulated sugar. white or organic cane sugar are the best choices.
Peanut Butter Cups. Choose your favorite peanut butter cups. I love unreal cups or Justin's!
