Method

Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 350°F (175°C). Grease and line an 8x8 inch baking pan with parchment paper, leaving some overhang for easy removal.

  2. 2

    Melt the Butter

    In a medium saucepan, melt the unsalted butter over medium heat. Once melted, remove from heat and let it cool slightly.

Mixing Dry Ingredients

  1. 3

    Combine Dry Ingredients

    In a large mixing bowl, whisk together the all-purpose flour, unsweetened cocoa powder, granulated sugar, baking powder, and salt until well combined.

Mixing Wet Ingredients

  1. 4

    Combine Wet Ingredients

    In the saucepan with the melted butter, stir in the Guinness beer, large eggs, and vanilla extract until fully combined.

Combining Mixtures

  1. 5

    Mix Wet and Dry

    Pour the wet ingredients into the bowl of dry ingredients. Stir until just combined; do not overmix.

  2. 6

    Add Optional Add-ins

    If desired, fold in chocolate chips and/or chopped nuts into the batter.

Baking

  1. 7

    Bake the Brownies

    Pour the brownie batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

  2. 8

    Cool and Serve

    Once baked, remove the brownies from the oven and let them cool in the pan for about 10 minutes. Use the parchment overhang to lift the brownies out of the pan, and let them cool completely on a wire rack before cutting into squares and serving.
