Bundt Cake:

  • 1 15.25 ounce yellow cake mix
  • 1 cup rootbeer
  • cup vegetable oil
  • 3 eggs


  • 2 cups powdered sugar
  • cup butter
  • Tablespoons milk
  • ½ teaspoon rootbeer extract


Bundt Cake:

  • Preheat oven to 350 degrees. Grease a 10" bundt pan.
  • In a medium mixing bowl, combine yellow cake mix, root beer, vegetable oil, and eggs until smooth, and pour into bundt pan.
  • Bake for about 35-40 minutes, until a toothpick inserted into the cake comes out clean.
  • Remove cake from oven and let it cool for about 20 minutes, and then flip it over onto a wire cooling rack and tap it out of the bundt cake pan. Let it cool completely before frosting.


  • Pour all ingredients into a medium mixing bowl and beat together until smooth. You can add more powdered sugar for a thicker texture, or more milk if you'd like your frosting a little thinner.


We love to serve this cake with vanilla ice cream, just like a root beer float! 🙂
