Ingredients
  

Brownie Batter
  • 0.5 cup unsalted butter melted
  • 1 cup granulated sugar
  • 0.5 cup brown sugar packed
  • 2 eggs large, room temperature
  • 2 tsp root beer extract
  • 1 tsp vanilla extract
  • 0.75 cup all-purpose flour
  • 0.5 cup unsweetened cocoa powder sifted
  • 0.25 tsp salt
Vanilla Frosting
  • 0.5 cup unsalted butter softened to room temperature
  • 2 cups powdered sugar sifted
  • 1 tsp vanilla extract
  • 1-2 tbsp heavy cream or milk

Equipment

  • Mixing bowls
  • 8x8 or 9x9-inch baking pan
  • Parchment paper
  • Hand mixer or stand mixer
  • Whisk

Method
 

  1. Preheat oven to 350°F (175°C). Line an 8x8 or 9x9 inch baking pan with parchment paper.
  2. In a large bowl, whisk the melted butter, granulated sugar, and brown sugar together until well combined.
  3. Whisk in the eggs one at a time, followed by the root beer extract and vanilla extract.
  4. Fold in the flour, cocoa powder, and salt until just combined. Do not overmix.
  5. Pour the batter into the prepared pan and smooth the top. Bake for 25-35 minutes, or until a toothpick inserted comes out with moist crumbs.
  6. Allow the brownies to cool completely in the pan before frosting.
  7. To make the frosting, beat the softened butter until creamy. Gradually add powdered sugar, mixing until smooth.
  8. Add vanilla extract and heavy cream, then beat on high speed until light and fluffy.
  9. Spread the frosting evenly over the cooled brownies. Cut into squares and serve.

Notes

For an even stronger root beer flavor, you can replace 2 tablespoons of the butter with 2 tablespoons of reduced root beer syrup.
