A delightful twist on classic brownies, these cups combine the rich flavors of peanut butter and Oreos for a treat that's both indulgent and easy to make.
Preheat your oven to 350°F (180°C) and line a 12-cup muffin tin with paper liners.
Using paper liners makes cleanup a breeze and ensures the brownie cups release easily.
In a mixing bowl, prepare the brownie mix according to the package instructions, combining it with eggs, oil, and water.
Mix until just combined to avoid overmixing, which can make the brownies dense.
Spread a small amount of peanut butter on top of each Oreo cookie and stack two cookies together.
Use a small spoon or knife to evenly spread the peanut butter for a consistent flavor.
Place each Oreo stack into a lined muffin cup and spoon brownie batter over the stacks, ensuring they are fully covered.
Tap the muffin tin gently on the counter to help the batter settle around the cookies.
Bake in the preheated oven for 18-20 minutes, or until the brownie tops are set and a toothpick inserted comes out clean.
Avoid overbaking to keep the brownies moist and fudgy.
Allow the brownie cups to cool completely in the tin before serving.
Cooling in the tin helps the brownie cups hold their shape for easier removal.
