Turtle Brownies

Preheat oven to 350 degrees F. Line a 9-inch square baking pan with foil, extending the foil over the edges of the pan. Lightly grease the foil.

Combine the beans, 1/2 cup chocolate pieces, and the melted butter in a food processor. Cover and process until smooth. Add egg, sugar, cocoa powder, and vanilla; cover and process until combined. Combine flour, baking powder, and salt in a bowl. Add to the chocolate mixture. Cover and process just until combined.

Spread the batter in the prepared baking pan. Bake 10 minutes. Sprinkle with nuts and the remaining 2 tablespoons chocolate pieces. Bake 10 to 12 minutes or until toothpick inserted 2 inches from edge of the pan comes out clean. Cool in the pan on a wire rack.

Before serving, drizzle with caramel topping. Cut into 16 brownies.
