Bake Sale Trifecta Bars
Description
The Bake Sale Trifecta Bars feature three distinct layers. The bottom brownie layer is rich and fudgy, made with butter, sugars, eggs, vanilla, flour, cocoa powder, and salt, baked to a moist texture. Above this lies a chocolate chip cookie dough layer, buttery and sweet, blended with brown sugar, granulated sugar, egg, vanilla, flour, baking soda, salt, and chocolate chips, providing a chewy contrast to the brownie.
The top layer is a rice krispie treat composed of butter, mini marshmallows, and crispy rice cereal, adding a sticky, crispy texture that contrasts the denser baked layers beneath. The bars are baked in a deep 9-inch square pan with foil lining and buttering to facilitate removal and even cooking.
This triple-layered dessert combines chocolate, cookie dough, and marshmallow characteristics into a single bar with varied textures from fudgy to chewy to crisp and sticky. The baking time ensures the middle cookie layer is cooked through without overbaking the brownie base or crust. Cooling completely before slicing is important to maintain the layered integrity.

- 1 teaspoon vanilla extract pure

Rice Krispie Treat Layer:
- 3 Tablespoons butter plus more for your hands, unsalted
- 1 10 - ounce marshmallows mini, bagged
- 3 cups crispy rice cereal
Instructions
- Preheat the oven to 325 degrees F. Line a 9-inch square, a 2-inch-deep baking dish with foil, leaving an overhang; butter the foil. Make sure it is a 9-inch square pan with tall sides so that it can all fit. Make the brownie layer: Beat the butter, granulated sugar, and brown sugar in a bowl with a mixer on medium speed until creamy, 4 minutes. Add the eggs and vanilla; mix until combined. Reduce the mixer speed to low; beat in the flour, cocoa powder, and salt. Spread in the prepared pan.
- Make the cookie layer: Beat the butter, brown sugar and granulated sugar in a clean bowl with a mixer on medium speed until creamy, 4 minutes. Add the egg and vanilla and mix until combined. Reduce the mixer speed to low; beat in the flour, baking soda, and salt. Stir in the chocolate chips. Gently spoon and spread the cookie dough on top of the brownie batter. Bake until a toothpick inserted into the center comes out clean, 35 to 40 minutes. Transfer to a rack and let cool completely in the pan.
- Make the cereal-treat layer: Melt the butter in a large saucepan over medium heat. Add the marshmallows; stir until melted. Remove from the heat and stir in the cereal. Let cool slightly. Butter your hands, then press the cereal mixture on top of the cookie layer. Refrigerate until set, about 30 minutes. Cut into squares.
