Mix in Dry Ingredients: Sift together all-purpose flour, cocoa powder, and salt before folding them gently into the buttery mixture. This step is crucial! Don’t overmix or you’ll end up with tough bars.

Add Vanilla & Peanut Butter Swirl: Stir in vanilla extract then pour half the batter into your prepared pan. Dollop spoonfuls of peanut butter over this layer and swirl it magnificently with a knife before topping with the remaining brownie batter.

Bake to Perfection: Bake your creation in preheated oven for 25-30 minutes until the edges look set but center still feels soft—like a little hug waiting for you inside! Let cool completely before cutting into squares.
