- Preheat oven to 350 degrees F. Line a 9x9x2-inch baking pan with foil, extending the foil over the edges of the pan. Grease foil; set aside.
- In a medium saucepan, melt and stir butter and chocolate over medium-low heat until smooth. Remove from heat. Stir in sugar, eggs, and vanilla. Stir in flour just until combined.
- Spread batter evenly in the prepared pan. Top evenly with spoonfuls of the Caramel Swirl. With a thin metal spatula, swirl into batter.
- Bake in the preheated oven for 25 to 30 minutes or until top springs back when lightly touched and edges are starting to pull away from sides of the pan. Cool in pan on a wire rack. Using the edges of the foil, lift the uncut brownies out of the pan. Cut into bars. Makes 16 brownies.
