Dulce de Leche Brownies

Found this recipe in time for Cinco de Mayo and found the express route to my man's heart with them.

*8 TBSP. unsalted butter, cut into pieces
*6 oz. semi-sweet chocolate, cut into pieces

*1/4 c. dutch-process cocoa

*3 large eggs

*1 c. sugar

*1 tsp. vanilla

*1 c. flour

*1 c. dulce de leche

Preheat oven to 350. Line an 8-inch square pan with foil making sure that it comes up the sides and has overhang on both ends. Grease bottom and sides with butter or cooking spray.

Melt butter in saucepan. Stir in chocolate pieces and melt over very low heat, stirring constantly. Remove from heat and whisk in the cocoa. Add eggs, one at a time. Stir in sugar, then vanilla, then flour.

Scrape 1/2 of the batter into the bottom of the prepared pan. Drop 1/3 of the dulce de leche by spoonfuls, evenly spaced, onto the brownie batter. Use a knife to gently swirl. Scrape the remaining batter on top, and drop the remaining dulce de leche on top. Gently swirl again.

Bake 35-40 minutes until the center is set. Remove from oven, allow to cool and cut. These are VERY rich, so although the recipe says it makes 12, I cut them small and get 25 from the pan.
