1. Preheat oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper.

2. Make brownie batter: In a bowl, whisk melted butter and sugar until smooth. Add eggs and vanilla, whisk until combined. Stir in cocoa powder, flour, salt, and baking powder until just mixed.

3. Make cheesecake filling: In another bowl, beat cream cheese, sugar, egg, and vanilla until smooth and creamy.

4. Assemble: Pour half the brownie batter into the pan. Sprinkle half the chopped Oreos evenly on top. Spread cheesecake mixture over the Oreos. Pour the remaining brownie batter over the cheesecake layer, then top with remaining Oreos.

5. Swirl: Use a knife to gently swirl the brownie and cheesecake layers together for a marbled effect.

6. Bake: 30–35 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.

7. Cool: Let cool completely before slicing into squares.

2. Peanut Butter Brownies
