Thanks to a cute friend named Brooke for this moist and delish brownie recipe. Brooke, you had me at Double Decker. :)

Double Decker Confetti Brownies
3/4 cup butter, softened
1 cup light brown sugar
2 1/2 tsp baking powder
1/3 cup unsweetened cocoa
1 cup mini baking M&M's
1 cup sugar
3 large eggs
1 tsp vanilla
2 1/2 cups flour, divided
1/2 tsp salt
1 Tbsp butter or margarine, melted

Preheat oven to 350°. Lightly grease a 13x9 inch baking pan; set aside. In a large bowl, cream butter and sugars until light and fluffy. Beat in eggs and vanilla. In medium bowl, combine 2 1/4 cups flour, baking powder and salt; blend into creamed mixture. Divide batter in half. Blend together cocoa and melted butter. Stir into one half of the dough. Spread cocoa dough evenly into prepared baking pan. Stir remaining 1/4 cup flour and 1/2 cup M&M's into remaining dough. Spread evenly over cocoa dough in pan. Sprinkle remaining 1/2 cup M&M's. Bake 25-30 minutes or until edges start to pull away from pan. Cool completely and cut into bars.
