How to Make

Prepare the Brownie Base

Start by preheating your oven to the temperature specified on your brownie mix box. Grease a 9×13-inch pan to ensure easy removal later. Following the instructions on the box, prepare the brownie mix until it reaches a smooth, batter-like consistency. Pour the mixture into the prepared pan and spread it evenly, ensuring every corner is filled. Bake until a toothpick inserted in the center comes out with a few moist crumbs, indicating the brownies are perfectly fudgy. Once baked, remove them from the oven and allow them to cool completely in the pan.

Create the Peanut Butter Layer

While the brownies cool, it’s time to prepare the luscious peanut butter layer. In a mixing bowl, combine the creamy peanut butter and softened unsalted butter, beating them together until smooth and well blended. Gradually add in the powdered sugar and vanilla extract, mixing until everything is fully incorporated. If the mixture feels too thick, add milk one tablespoon at a time until you achieve a creamy, spreadable consistency. Once your peanut butter layer is ready, spread it evenly over the cooled brownies, ensuring that every bite will have that delightful peanut butter flavor.

Prepare the Chocolate Ganache

Now, let’s elevate these brownies even further with a rich chocolate ganache. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Remove it from the heat and pour it over the chocolate chips in a bowl. Allow it to sit for about 2-3 minutes; this will soften the chocolate. Gently stir the mixture until it transforms into a smooth and glossy ganache. This step is crucial as it adds an indulgent finish to your brownies.

Finish with Ganache

Pour the warm ganache over the peanut butter layer, using a spatula to spread it evenly across the top. The glossy chocolate will create a beautiful finish and complement the flavors perfectly. After spreading the ganache, place the brownies in the fridge and let them chill for at least one hour. This will help the layers set and make slicing easier.

Slice and Serve

Once the brownies are well chilled, it’s time to slice them into squares. Use a sharp knife to cut through the layers, ensuring you get a piece of brownie, peanut butter, and chocolate ganache in each bite. Serve them on a beautiful platter to impress your guests or keep them in a container to enjoy throughout the week. Either way, these peanut butter brownies are sure to bring joy and satisfaction to everyone who tries them.

Tips for Success

  • Use Room Temperature Ingredients: Ensure your butter and cream cheese are at room temperature for easier mixing and a smoother texture.
  • Don’t Overbake: To achieve the fudgy texture, be careful not to overbake the brownies check them a few minutes before the suggested time.
  • Chill the Ganache: If your ganache seems too runny, let it sit at room temperature for a few minutes to thicken before pouring it over the brownies.
  • Slice with a Warm Knife: For clean cuts, dip your knife in hot water, wipe it dry, and then cut through the brownies.
  • Store Properly: Keep the brownies in an airtight container to maintain their freshness and avoid drying out.

Variations to Try

  • Add Nuts: Incorporate chopped walnuts or pecans into the brownie batter for an added crunch.
  • Swirl in Jam: Add a layer of raspberry or strawberry jam between the brownie and peanut butter layers for a fruity twist.
  • Use Dark Chocolate: For a richer flavor, substitute semi-sweet chocolate chips with dark chocolate chips in the ganache.
  • Make it Vegan: Replace the butter with a plant-based alternative and use dairy-free chocolate chips for a vegan version.
  • Top with Sea Salt: Sprinkle a pinch of sea salt on the ganache before it sets for a delightful sweet and salty contrast.

  • Skipping the Cooling Step: Allowing the brownies to cool completely is essential, as it prevents the layers from melting into each other.
  • Not Measuring Ingredients Accurately: Baking is a science; be sure to measure ingredients carefully for the best results.

  • Overmixing the Batter: Mix just until combined to avoid dense brownies; overmixing can lead to tough texture.
