Oreo Brownies with Marshmallows
- 1 brownie mix + ingredients included for 9x9 pan size
- 12 oreo sandwich cookies
- 2 cups mini marshmallows
Mississippi Mud Frosting
- ⅓ cup unsalted Butter
- 4 Tablespoons milk
- 2 Tablespoons unsweetened Cocoa Powder
- 2 ¼ cups powdered sugar sifted
- 1 teaspoon vanilla extract
- 1 dash salt
- ⅔ cup chopped pecans or walnuts optional
Oreo Brownies with Marshmallows
Preheat the oven to 325°. Spray a 9×9 pan with cooking spray and set aside. Line with parchment paper for easy removal.
Make brownies according to box instructions.
Pour some of the brownie mix into the pan and layer Oreo cookies on top.
Add remainder of brownie mix on top of brownies. It’s ok if the Oreos aren’t completely covered. Bake brownies according to box instructions or until
until the center of the cake springs back lightly when pressed on, or a toothpick comes out clean.
Immediately add the marshmallows over the top of the brownies and return to the oven. Bake for 2-3 minutes, just until the marshmallows are starting to puff and melt.
Remove the brownies from the oven and set aside to make the frosting.
Mississippi Mud Frosting
In a medium saucepan over medium heat, combine the butter, milk, and cocoa powder. Cook until simmering and simmer for 2-3 minutes, stirring constantly.
Remove from the heat and whisk in the vanilla and powdered sugar. You can use a hand mixer to get the frosting nice and smooth if you would like.
Drizzle the warm frosting over the brownies and allow to chill in the fridge for 20-30 minutes before serving.
