Peanut Butter-Hazelnut Brownies Recipe

Preheat oven to 350 °. In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine the flour, cocoa, baking powder and salt; gradually add to creamed mixture. Fold in malted milk balls. Spread into a greased 13x9-in. baking pan. In a small microwave-safe bowl, combine peanut butter and Nutella; cover and microwave at 50% power for 1-2 minutes or until smooth, stirring twice. Drizzle over batter; cut through batter with a knife to swirl. Bake 35-40 minutes or until a toothpick inserted near the center comes out clean (do not overbake). Cool on a wire rack.
