Directions

1. Preheat the oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper.

2. Make the brownie batter:

   • In a bowl, melt the butter and mix in granulated and brown sugars until smooth.

   • Add eggs and vanilla extract, whisking until well incorporated.

   • Stir in cocoa powder, flour, salt, and baking powder until just combined.

   • Fold in chocolate chips or chunks.

3. Prepare the peanut butter filling:

   • In a small bowl, mix creamy peanut butter with powdered sugar (if using) to form a thick but spreadable paste.

4. Assemble the brownies:

   • Pour half of the brownie batter into the prepared pan and spread evenly.

   • Spoon the peanut butter filling over the batter and gently spread into an even layer.

   • Pour the remaining brownie batter on top and smooth out.

5. Bake for 30–35 minutes or until the edges are set and the center is slightly soft but not jiggly.

6. Cool completely before cutting into squares for clean slices.

FAQs

Can I use natural peanut butter?

Yes, but it should be well-stirred and slightly thick. Avoid very runny textures, as they may not hold up in baking.

Can I make these brownies without powdered sugar in the filling?

Yes, but the powdered sugar helps thicken the peanut butter for a more structured layer.

How do I know when the brownies are done?

The edges should be firm and the center set. A toothpick inserted should come out with moist crumbs but not raw batter.

Can I use boxed brownie mix?

Yes, prepare the boxed mix as directed and layer with the peanut butter filling the same way.

Can I add other mix-ins?

Absolutely. Chopped nuts, white chocolate chips, or even caramel bits can be added.

Why is my peanut butter layer sinking or disappearing?

The brownie batter may be too thin, or the peanut butter too runny. Use a thicker peanut butter mixture and layer it evenly.

Should I chill before slicing?

Yes, chilling helps achieve clean, even slices, especially for layered or stuffed brownies.

Can I swirl the peanut butter instead of layering?

Yes, for a marbled effect, drop spoonfuls of peanut butter over the top and swirl gently with a knife.

Are these freezer-friendly?

Yes, they freeze well individually wrapped for easy snacks later.

Can I use almond or cashew butter instead?

Yes, you can substitute with any nut butter of your choice.
