For the Brownies
  1. 2/3 cup of flour
  2. 1/2 cup of cocoa powder
  3. 6 oz of chopped semi sweet chocolate
  4. 3 oz of white chocolate
  5. 4 tablespoons of butter
  6. 3 large eggs
  7. 1/2 cup of white sugar
  8. 1/2 cup of brown sugar
  9. 8 oz of Dad's root beer
  10. 2 teaspoons of vanilla
  11. 1/2 teaspoon of salt
For the Frosting
  1. 1/2 cup of butter (room temperature)
  2. 1/3 cup of Dad's root beer, no foam
  3. 5 cups of powdered sugar
  4. 1/2 teaspoon of root beer extract (if you can find it - entirely optional)
For the Brownies
  1. Preheat your oven to 375° F (190 degrees C, Gas Mark 5).
  2. Line a 9×9 baking dish with aluminium foil and spray lightly with cooking spray or lightly coat with melted butter.
  3. Sift flour, cocoa powder and salt in a bowl and set aside.
  4. Over a double boiler (or in microwave) melt the butter, semi-sweet and white chocolates together.
  5. Remove from heat when just melted and allow to cool for 5 minutes.
  6. Using your mixer mix the eggs, sugars and vanilla together.
  7. Slowly add in the cooled chocolate mixture.
  8. Now add half the flour and half the root beer. Mix on low, scraping the sides.
  9. Repeat with the remaining flour and root beer until just combined. Batter will be on the thin side.
  10. Pour batter into your prepared pan and bake for 25 minutes, until the centre is just set.
  11. Let cool completely before cutting or frosting.
For the Frosting
  1. Beat butter on medium speed until smooth.
  2. Slowly add in your powdered sugar and mix in.
  3. Now add your root beer and extract, if desired.
  4. Beat on medium until smooth and all ingredients are incorporated.
  5. Coat the top of your baked brownies before cutting, leave to firm up slightly.
  6. Cut your root beer frosted brownies into the desired sections and serve!
  1. It's best to leave the root beer open to allow some of the fizz to get away - that way you don't have excess foam, which would ruin the recipe.
  2. Drizzle with A&W Root Beer Float Dessert Topper to really finish it off!
