Dulce de Leche Apple Bars with Browned Butter Icing

Preheat oven to 350°F. Grease and flour a 9x9-inch square baking pan.

In a medium bowl, whisk together flour, baking powder, baking soda, cinnamon and salt. Set aside.

In a large mixing bowl, use an electric mixer to beat butter, sugar, eggs and vanilla until fluffy.

Stir flour mixture into the wet mixture, just until combined. Carefully stir in apples.

Spoon 2/3 of the batter into the prepared pan. Drop dulce de leche by heaping Tablespoons over batter. Drag a butter knife through dulce de leche to swirl through the batter. Drop remaining batter over dulce de leche.

Bake 25 to 30 minutes, or until browned and firm to touch. Let cool completely.

Prepare icing: In a small saucepan, heat butter over medium until it begins to brown. Remove from heat. Add to a bowl with powdered sugar, vanilla and half/half. Beat on high speed with electric mixer until creamy. Drizzle and spread over bars, and chill until icing is set.

For cleanest cuts, chill completely and slice into the bars with a sharp, thin knife. Keep refrigerated until ready to serve.
