These Little Caesar's Cookie Dough Brownies are rich, fudgy brownies topped with whipped cookie dough frosting, mini chocolate chips, and colorful M&M's. A copycat bakery treat made right at home!
Preheat the oven to 350 degrees F. Line a 9-inch square metal baking dish with parchment paper. Set it aside.
In a medium sized saucepan, melt butter over medium heat. Remove from heat, then add in semi-sweet chocolate chips and the sugar. Mix until combined and chocolate is melted.
Add in eggs, one at a time, stirring to combine. Add in vanilla extract.
Add cocoa powder, flour, salt, and baking powder. Using big strokes, mix just until dry ingredients are incorporated to the batter.
Pour batter into prepared baking dish and bake for 40-45 minutes. Remove from oven and cool completely before adding the frosting.
For the frosting, beat butter with brown sugar for 3-4 minutes, until creamy. Add in salt, powdered sugar, vanilla, and evaporated milk. Beat for 3-4 minutes until light and fluffy. Fold in mini chocolate chips.
Spread frosting over cooled brownies. Sprinkle the top with M&M's.
Notes
Do not overmix the brownie batter. After adding the dry ingredients, mix just until you no longer see flour.
Evaporated milk can be substituted with your favorite choice of milk. However, I find the flavor of evaporated milk mimics chocolate chip cookies best.
Use a plastic knife when slicing the brownies for cleanest cuts.
Refrigerate brownies before slicing if desired, but not necessary.
Store brownies in airtight container at room temperature for up to one week.
Freeze brownies for up to 3 months in airtight freezer safe container.
