I am SO excited about today’s post. Yes, because of the decadent Chocolate Peanut Butter Brownies that are staring you down and begging to be made, but also because of Jessica’s new cookbook, Seriously Delish.

For the Brownies:

For the Peanut Butter Filling:

Ganache Topping:

  • 8 ounces milk chocolate chopped
  • 1/2 cup heavy cream
  • 1 1/2 cups chopped peanut butter cups


  • Preheat the oven to 350 degrees F. Spray a 9x13-inch baking dish with nonstick spray.
  • For the brownies, add the butter and chopped chocolate to a microwave-safe bowl and microwave until melted, 30-60 seconds. Once the chocolate is semi-melted, stir constantly to melt the rest. Set aside and allow the mixture to cool for 5 minutes.
  • In a small bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
  • In a large bowl, whisk together the melted butter-chocolate mixture and granulated sugar. Whisk in the eggs, egg yolk, and vanilla extract, stirring until a smooth batter forms. With a large spoon, mix in the dry ingredients until combined. Stir in the chocolate chips. Add the batter to the baking dish. Bake until the brownies are set and no longer jiggly in the middle, 25-30 minutes. Remove from the oven and let them cool for 30 minutes.
  • For the peanut butter filling, stir together the melted peanut butter, powdered sugar, and coconut oil until smooth. The peanut butter will be warm and will melt the coconut oil, so stir until melted. Pour the filling over the brownies, using a spatula to spread it around the top. Let cool completely and firm up, about 20 minutes.
  • For the ganache, add the chocolate to a large bowl. Heat the cream in a small saucepan over medium heat just until it bubbles around the edges. Remove the cream from the heat and pour it over the chocolate. Let the mixture stand for 30 seconds, then stir until the chocolate melts and a smooth ganache comes together, about 1-2 minutes. Pour it over the top of the brownies, then cover with the chopped peanut butter cups. Let the brownies sit for 30 minutes before cutting.
  • Note-the brownies will stay fresh for 2 to 3 days at room temperature if covered or kept in an airtight container. You can also keep them in the fridge, they will last a few days longer.

  1. these have to be pinned, and then eaten multiple times. I mean, seriously? How is this recipe real?

  2. Wow that title is a mouthful! oh man these brownies look amazing, definitely something my husband would LOVE! He’s all over anything peanut butter and chocolate ๐Ÿ™‚
    I’ve heard the Seriously Delish book is amaze but I haven’t had a chance to pick it up ๐Ÿ™ #lifewithaninfant

  3. I made these on Sunday. They’re my new favorite bar recipe. Seriously off the charts! I love Jessica’s blog. I have to get her book!

  4. Your photos of the brownies compelled me to bake a batch ASAP! So glad I did. Thanks for sharing. I will have to check out Jessica’s blog.

  5. Hello! I just made these tonight and they are delicious!!! I had a question for you, though. My brownies rose significantly more on the edge than the center. I thought I spread the batter pretty evenly, but it led to this kind of “ledge” that held the peanut butter filling and ganache in. So, for that poor person who doesn’t like brownie edges, they’re also getting gipped on filling! Do you happen to have a method to prevent that? (Usually I have the opposite problem where the center rises more!!)

    1. I am not sure. The brownies are pretty even for me. Maybe press the edges down slightly?

    2. I have the same issue, but as soon as they come out of the oven I flatten the edges with a spatula/back of spoon so that it levels out more. Then I allow it to cool. The top “cracks” a little, but you cover that up with the peanut butter & ganache layer anyway so no one sees it. It makes a nice level surface to top with the other layers.

  6. 5 stars
    These have become my go-to for peanut butter & chocolate brownies. It has such a great balance of chocolate and peanut butter flavor & looks impressive. Just as a tip when I’ve taken mine out of the oven the edges are raised, so i quickly level out the top of the brownies with the back of a spatula/spoon. Then I let it cool. This makes it so that the peanut butter & ganache layers don’t pool to the middle. Thank you for such a great recipe!
