Ingredients

The following ingredients have 12 Servings
  • 440 ml can of Guinness (15 ounces)
  • 2 cups flour
  • 2 cups sugar
  • ¾ cup cocoa powder (plus a little extra for the pan)
  • 2 teaspoons baking soda
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • ½ cup neutral-flavored oil
  • 2 teaspoons vinegar
  • ½ cup chocolate chips
  • ½ cup softened butter (use vegan, if needed)
  • 1 ½ cups powdered sugar
  • 1 ½ tablespoons Irish whiskey

Instruction

  • Preheat your oven to 350 degrees. Grease a 11x9 inch baking sheet with butter or coconut oil then sprinkle some cocoa powder over the top. Shake the baking sheet so the cocoa powder covers the butter.
  • Pour half the can of Guinness into a small pot and bring it to a boil over high heat. Set the pot aside.
  • While the Guinness is heating, make the rest of the cake. Whisk the flour, sugar, cocoa powder, baking soda, baking powder, and salt together in a large bowl. Add the oil, vinegar, and the remaining Guinness in the can and whisk. Pour the hot Guinness into the bowl and carefully whisk it into the batter. Stir in the chocolate chips.
  • Pour the batter into the prepared baking sheet and bake in the oven for 25-30 minutes, or until a toothpick inserted into the middle of the cake comes out clean. After 10 minutes, remove the cake from the baking sheet and let it cool completely on a cooling rack. Once it is completely cool, cover it with the frosting.
