Guinness Brownies with Caramel Fudge Frosting
Course: Dessert
Cuisine: American
Servings: 20 brownies
For the brownies
  • 5 tbs unsalted butter, cut into cubes
  • 1 1/2 cups semi-sweet chocolate chips
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar, packed
  • 3 eggs
  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 tsp kosher salt
  • 1 1/4 cup Guinness beer (or other stout)
  • 1 cup semi-sweet chocolate chips
For the frosting
  • 8 tbs unsalted butter, cut into cubes
  • 1 cup light brown sugar, packed
  • 2 tbs light corn syrup
  • 1 can sweetened condensed milk
  • 1 pinch of kosher salt
  • 1/2 cup white chocolate chips
To make the brownies
  1. Preheat the oven to 350 degrees F. Prepare a 9x13-inch pan by lining it with foil, using enough foil so that some drapes over the sides. Set the pan aside.

  2. In a double boiler, melt the butter and chocolate chips together, stirring regularly. Once everything is melted, take the bowl off of the heat.

  3. Add the sugars and mix well. Add the eggs, one at a time, making sure to mix well between eggs.
  4. In a separate bowl, whisk the flour, cocoa powder, and salt together. A little at a time, add the dry ingredients to the chocolate mixture, alternating with the Guinness. Fold in the chocolate chips.

  5. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a knife comes out clean when inserted into the middle of the brownies. Let the brownies cool a bit while you make the fudge frosting.

To make the frosting
  1. In a medium sauce pan, melt the butter. Add the brown sugar and corn syrup and stir to combine. Add the sweetened condensed milk and mix. Do not boil the mixture. Only heat it up enough so that it will melt the white chocolate chips. Add the white chocolate and a pinch of salt. Remove the sauce pan from the heat and stir until they melt completely.

  2. Pour the mixture over the brownies and spread into an even layer. Let the fudge frosting set up at room temperature for at least an hour (ideally overnight).
  3. Top the brownies with chocolate chips.
