Tastes like a root beer float in cupcake form. Perfect easy summer dessert!
These root beer float cupcakes are simple to make because they start with a cake mix. They're perfect for hot days when you want something sweet but not complicated.
Ingredients You'll Need
- 15.25 ounce package white cake mix
- 2 1/4 cups cold root beer, divided
- 1/4 cup vegetable oil
- 2 large eggs
- 2 envelopes whipped topping mix (Dream Whip)
How to Make Root Beer Float Cupcakes
-
Preheat your oven to 350°F and line your muffin tin with cupcake liners.
-
In a large bowl, combine the cake mix, 1-1/4 cups root beer, oil, and eggs.
-
Beat on low speed for 2 minutes (or stir by hand for 3 minutes) until well combined.
-
Use a cookie scoop to portion the batter evenly into the cupcake liners for consistent sizing and even baking.
-
Bake for 18–22 minutes or until a toothpick inserted in the center comes out clean.
-
Cool completely on a wire rack.
Make the Whipped Root Beer Frosting
-
In a medium bowl, combine the 2 envelopes of whipped topping mix and remaining 1 cup of root beer.
-
Beat until soft peaks form.
-
Frost cooled cupcakes generously and top with a cherry and a small straw for that classic float feel!
Tips for the Best Cupcakes
-
Flavor matters: I used Barq’s, which has a strong taste that came through in both the cupcakes and the frosting. If you’re using a different brand, you may want to add root beer extract to boost the flavor.
-
Use a cookie scoop for neat, even cupcakes.
-
Don’t overbake—check at the 18-minute mark.
Can I Make These as a Cake or Donuts?
Absolutely! You can pour the batter into a greased 13x9-inch pan and bake at 350°F for 30–35 minutes, or use your donut pan, just reduce the baking time to 8–10 minutes or until a toothpick comes out clean.
