  • ¼ cup root beer

Notes

  • Use cold root beer to make the cake to help it mix into the batter.
  • Don't over mix the batter. Over mixing can cause the cake to be dense and tough.
  • Make sure to grease your pan well. This will make it easier
  • Let the cake cool before adding the glaze.
  • Depending on how thick or thin you would like the root beer glaze, you can adjust the amount of root beer you use.
  • Let the glaze set before slicing.
