How to Make Peanut Butter Brookies

Phase 1 – Prep

Preheat your oven to 350°F (175°C).
Prepare a 9×13-inch baking pan by greasing it lightly or lining it with parchment paper.
Gather all the ingredients to ensure a smooth cooking experience.
In a mixing bowl, cream together the softened unsalted butter and both types of sugar until light and fluffy.
Add in the smooth peanut butter and mix until well combined.
Incorporate the egg, egg yolk, milk, and vanilla extract until the mixture is smooth.
Mix the baking soda, salt, and all-purpose flour in a separate bowl.
Gradually add the dry ingredients to the wet mixture until fully combined.
Fold in the peanut butter chips and set the mixture aside.

Phase 2 – Cook/Assemble

In another bowl, prepare the brownie mixture by creaming the unsalted butter, neutral oil, and granulated sugar until light.
Add the eggs and vanilla extract to the brownie mix, stirring until well combined.
Incorporate the cocoa powder, baking powder, and salt into the mixture, followed by the all-purpose flour.
Fold in chocolate chips until evenly distributed.
In the prepared baking pan, spread the brownie mixture evenly on the bottom.
Spoon the peanut butter mixture evenly on top of the brownie layer—swirl them slightly for a marbled effect.
Bake in the preheated oven for 25-30 minutes, or until the edges are set and a toothpick inserted comes out clean.

Phase 3 – Serve

Once baked, remove the pan from the oven and allow the brookies to cool in the pan for at least 15 minutes.
Cut into squares or rectangles for easy serving.
Serve warm, or at room temperature with a glass of milk or your favorite dairy-free alternative.
Store any leftovers in an airtight container at room temperature.

Pro Tips for the Best Results

For a richer taste, brown the butter before mixing.
Use room temperature eggs to help create a fluffier texture.
Substitute coconut flour for all-purpose flour for a gluten-free option.
Try sprinkling some sea salt on the top before baking for added flavor.
Store your brookies in an airtight container to keep them fresh longer.

Common Mistakes to Avoid

One of the most common mistakes is overmixing the peanut butter mixture. This can result in a tough texture rather than the desired chewy brookie. Mix just until combined to keep the brownies tender.

Another misstep is neglecting to properly measure your flour. Too much flour can lead to dense and dry brookies. Use a kitchen scale for accuracy or fluff the flour with a spoon before spooning it into your measuring cup.

Lastly, overbaking is a frequent pitfall. Keep a close eye on your brookies and pull them out of the oven as soon as a toothpick inserted into the center comes out mostly clean. This ensures that they remain soft and fudgy.

Recipe Variations

Gluten-Free: Substitute all-purpose flour with a gluten-free blend.
Dairy-Free: Use vegan butter and dairy-free chocolate chips.
Spicy: Add a pinch of cayenne or chili powder for a kick.
Herbal: Stir in a bit of fresh mint or basil for unique flavor.
Air Fryer: Cook in an air fryer at 320°F (160°C) for 15-20 minutes.
