Ok I’m a genius. I love root beer floats, so a root beer flavored cupcake was a no brainer. Of course I discovered that I wasn’t the only genius to have this idea.

After doing a search, I did find a few different recipes for root beer float cupcakes. Nothing really like the picture I had formed in my head. To find the cupcake recipe I wanted something that was moist. The Joy of Baking’s Vanilla Cupcake recipe fit the bill. Next I wanted to do a cream filling. Our Best Bites has the perfect one! Then a glaze and Wilton’s Buttercream frosting for the top.

Enjoy!

My ingredients

Sugar and Butter creamed until fluffy.

Add the eggs

Add the concentrate

Dry ingredients whisked together

Add the milk and dry ingredients in intervals

Filled cupcake pans

Baked cupcakes

Fillings milk mixture

Creamed butter and sugar

Finished Filling

I cut wells to add the filling

Filled with glaze

Finished frosting

Root Beer Cupcakes


  • 1/2 cup (113 grams) unsalted butter temperature
  • 2/3 cup (130 grams) granulated white sugar
  • 3 large eggs
  • 2 1/2 teaspoon root beer concentrate
  • 1 1/2 cups (195 grams) all purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1/4 cup (60 ml) milk

Preheat oven to 350 degrees F (177 degrees C) and line 12 muffin cups with paper liners.
In the bowl of your electric mixer, or with a hand mixer, beat the butter and sugar until light and fluffy. Add the eggs, one at a time, beating well after each addition. Beat in the root beer concentrate.
In a separate bowl whisk together the flour, baking powder, and salt.
With the mixer on low speed, alternately add the flour mixture and milk, in three additions, beginning and ending with the flour. Scrape down the sides of the bowl as needed.
Evenly fill the muffin cups with the batter and bake for about 18-20 minutes or until nicely browned and a toothpick inserted into a cupcake comes out clean. Remove from oven and place on a wire rack to cool. Once the cupcakes have completely cooled, frost with icing. If you want flat topped cupcakes then slice off the dome of each cupcake, with a sharp knife, before frosting. If you want to pipe the frosting, I like to use a large Wilton 1M star decorating tip.

Cream Filling

  • 3 T Flour
  • 1/2 C milk
  • 1/2 C real butter
  • 1/2 C sugar (that’s granulated sugar, not powdered sugar)
  • 1 t vanilla extract, or other flavor if you wish.

Whisk together the flour and the milk. Heat in a small sauce pan on medium heat.
Whisk continuously until it starts to thicken. Let it cook, while stirring, until you can start to see the bottom of the pan.
It’s okay if you have lumps, because we’re gonna strain those out right now. Place the mixture in a mesh strainer and stir with a rubber spatula to push it through.
You should end up with a nice, smooth mixture. It’s almost like pudding before it’s set.
Put this mixture in the fridge and let it cool completely, it’s fine if it stays in there long enough to get chilly, you just don’t want it warm at all. When it is chilled, you can move on to the following step.

It an electric stand mixer, beat the butter and the sugar for a minute or two until well combined and fluffy. You’ll want to use the whisk attachment on a stand mixer, not the flat paddle. Then while beating, add in the thickened milk mixture and the vanilla. Beat to combine and then scrape down the sides.
Beat on med-high for 7-8 minutes.

Root Beer Glaze

  • 2 T confectioners’ sugar
  • 1/8 t root beer concentrate
  • Milk to your likeness

Just mix all together and drizzle on your cupcakes

Buttercream Frosting

Ingredients:

  • 1/2 cup solid vegetable shortening
  • 1/2 cup (1 stick) butter or margarine softened
  • 1 teaspoon clear vanilla extract
  • 4 cups sifted confectioners’ sugar (approximately 1 lb.)
  • 2 tablespoons milk

Makes: About 3 cups of icing.

Instructions
(Medium Consistency)
In large bowl, cream shortening and butter with electric mixer. Add vanilla. Gradually add sugar, one cup at a time, beating well on medium speed. Scrape sides and bottom of bowl often. When all sugar has been mixed in, icing will appear dry. Add milk and beat at medium speed until light and fluffy. Keep bowl covered with a damp cloth until ready to use.
For best results, keep icing bowl in refrigerator when not in use. Refrigerated in an airtight container, this icing can be stored 2 weeks. Rewhip before using.
For thin (spreading) consistency icing, add 2 tablespoons light corn syrup, water or milk.
For Pure White Icing (stiff consistency), omit butter; substitute an additional 1/2 cup shortening for butter and add 1/2 teaspoon No-Color Butter Flavor. Add up to 4 tablespoons light corn syrup, water or milk to thin for icing cakes.

I am taking the “T” to stand for teaspoon or is that tablespoon? Yeah…. I’m a newbie.

Thanks

Yes it does mean Tablespoon. I should be more clear. Sorry!

Capital “T”s are usually Tablespoon and lower case “t”s are teaspoon is all recipes as far as I know. :)

I have a question i am new to baking, so i am kinda lost on what root beer concentrate is. Could you please tell. Thanks so much Brittany

Hi Brittany,

Root Beer concentrate is something that McCormicks makes. Not all stores sell it, if they do it is with their other extracts. I had to buy mine online since I couldn’t find it here.

I found the root beer concentrate at Wal-Mart.

Hi,
Here in the Detroit area, there is a local company that makes candy flavored vodka, “Hard luck Candy Vodka” anyway, they have a root beer flavored one that I think would be great to try instead of the root beer extract. I know there is root beer schnaps available as well. For an adult crowd..;)

Oh that does sound like a great idea! I will look for it to try.

Sadly I am disappointed in these cupcakes. The cupcake itself is very dry. I made mini cupcakes so maybe that is why they are dry since I am not able to put the cream mixture in the inside which would probably help. The glaze and frosting are very good. I substituted the vanilla in the frosting for some root beer concentrate. Probably about the same amount as the vanilla but I didn’t specifically measure. I would like to know if other people had the same results or if I did something wrong to the batter. Thanks

I am sorry they turned out that way for you! Since I haven’t used this recipe for awhile I am going to play with it and see if I can’t get a more moist cupcake. When I do I will update this post!

Julie, I would try the recipe as it was written before you comment on how dry your cupcakes were. It is not really fair to the baker.

I am trying this recipe and I plan to add a pkg of vanilla pudding to the mix to add moisture. I will let you know the results.

I love root beer floats as well. Didn’t know that you can make cupcakes with that flavor. Thanks for this recipe!

Just made these today, and they are so good. Read comment about being too dry. I just added extra milk- 1/2 cup instead of 1/4 cup. Perfect. Be careful not to overbake. Thanks for sharing recipe

Since this has a filling do you think its a good idea to keep them in the fridge?

Reply

Jess January 11, 2013 at 12:59 pm

I am sure you probably could keep them in the fridge, but I found that I didn’t need to.

Can we use drinking root beer or does it make it runny?

Reply

Jess October 30, 2013 at 8:15 pm

It would make the batter runny. I’ve not tried it to see how well the cake would bake.
