Instructions

Make the brownie batter...

  • Add a 14 ounce stout beer into a saucepan and bring to a simmer over medium high heat 
  • Once simmering, reduce the heat to medium and simmer until the beer is reduced to 1/2 cup in volume (about 15 minutes)
  • While the beer is reducing, preheat your oven to 350 degrees and grease a 9” round cake pan or 11”x7” baking dish and line with parchment paper
  • Whisk 1 cup of all purpose flour with 1/2 cup of dark dutch cocoa powder, 1 teaspoon of baking powder, 1 teaspoon of baking soda and 1 teaspoon of salt in a large bowl 
  • In a separate bowl, whisk 3/4 cup of granulated sugar, 1/4 cup of brown sugar, 3/4 cup of vegetable oil, 2 large eggs and a teaspoon of vanilla extract until fully combined 
  • Add the wet ingredients to the dry ingredients and mix until just combined 
  • Add the 1/2 cup of reduced stout beer and mix until evenly distributed
  • Transfer the batter into the prepared cake pan

Make the walnut crumble...

  • Combine 3/4 cup of brown sugar with 1/2 cup of chopped walnuts, 1 teaspoon of ground cinnamon and 1 1/4 cups of all purpose flour in a small bowl
  • Add 1/2 cup of melted butter and mix until large crumbs form

Assemble & bake the brownies...

  • Sprinkle the crumble evenly over the cake batter 
  • Bake the cake in a 350 degree oven for about 45 minutes or until a toothpick will come out of the center mostly clean with no wet batter
  • Transfer the pan onto a cooling rack and let cool completely before transferring the brownies out of the baking dish 
  • Slice and enjoy!
  • Store leftovers at room temperature in an air tight container
