This Root Beer Float Cupcakes and Frosting is easy because it starts with a boxed mix and gets some outrageous flavor.

Jump to:
Who doesn't love root beer floats? This cupcake form is an easy recipe and oh-so-decadent.
I love the delicious flavor root beer adds to a recipe, but I didn't really want my kiddos to have sugary soda in their cupcakes - I mean, it's enough they're having cupcakes, right? This recipe includes no soda at all and uses root beer flavoring instead.
And, I used a doctored-up boxed cake mix! GASP!
Ok, so it's no secret that I often bake with boxed mixes. Let's face it, life is busy and I'll take all the shortcuts I can. When it comes right down to it, I'd rather spend extra time with my family, than baking from scratch. But, that doesn't mean we're skimping on taste.
My friends know that I always say you can get away with boxed cake mixes all day long if you make the frosting from scratch - which is a cinch!
If you prefer to make your root beer cupcakes from scratch, use this Easy Vanilla Cupcakes recipe and add the root beer flavoring to it instead of vanilla extract.
I love the cream cheese in this frosting, which softens the sweetness and adds some creaminess to the texture. The root beer flavoring adds both flavor and beautiful caramel color to the cake and buttercream frosting.
🧂 Ingredients
Cake
- French vanilla cake mix plus ingredients called for on the box
- root beer flavoring
Frosting
- butter
- cream cheese
- powdered sugar
- milk
- root beer flavoring
I used a flavoring oil to achieve the root beer flavor. It is similar to an extract, but a bit stronger - in fact 3 to 4 times stronger - so much so that the first attempt ended up with a frosting that was waaaaay to "bicy" (spicy) as my daughter would say! You need only about a quarter of the flavoring oil as you would need using a root beer extract, so it's a really great value. Plus, the oils are gluten-free and Kosher certified.

🔪Instructions
This is meant to be a brief overview of the root beer cupcakes and frosting recipe. For step-by-step instructions and a full printable recipe card with ingredients, please scroll down to the teal box below or Jump to Recipe.
Cake
- Follow the instructions on the box to prepare the cake mix. Add in the root beer flavor with the eggs.
- Pour into cupcake papers or greased muffin tins and bake according to the directions on the box.
- Remover the cupcake pan from the oven and transfer the cupcakes to a cooling rack.
Frosting
I prefer to make homemade frosting in my electric mixer, however, you can also use a hand held mixture.
- While the cupcakes cool, remove the butter and cream cheese from the refrigerator to soften.
- In a large bowl, beat the butter and cream cheese at medium speed until combined and soft. Add about half the powdered sugar and 1 tablespoon of milk. Beat on low until combined.
- Add the remaining powdered sugar and again beat slowly. Add additional milk 1 teaspoon at a time until you have the desired consistency.
- For piping, I generally like a stiffer frosting. Insert your desired tip into your piping bag and then fill it with the frosting. Be sure the cupcakes are completely cool before frosting.
🍴 Serving Suggestions
You can get creative when decorating these root beer float cupcakes. I added some root beer barrel candies and fun paper straws (cut in half).
The first time I made these fun cupcakes, the straws thoroughly confused my then 3-year-old who wanted to know why we needed to drink our cupcakes!
