Step 2: Add the Dry Ingredients

In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Step 3: Swirl in the Peanut Butter

Drop spoonfuls of peanut butter onto the brownie batter, then use a knife to swirl the peanut butter into the batter to create a marbled effect.

Step 4: Bake the Brownies

Pour the batter into the prepared baking pan and smooth the top with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
