There is something that few people know about me. So heinous, so frightening, so down-right childish…
I am addicted to root beer floats. Yes I am.
I am old enough to remember real root beer, the kind that was made fresh at the A & W drive ins. Wow. And, I am going to learn to make root beer myself. It is one of my goals. I love Birch beer to, but we have to have it imported because you can’t get it here. Anyway…
Yesterday morning I wanted a root-beer float, but I was cold. And I don’t like eating ice cream when it is cold. In fact, at 48, I am not getting hot flashes, I am getting cold flashes. Hey, dare to be different, right?
What a dilemma!
I grabbed one of my favorite cake recipes and decided to try to make a cake. But I didn’t think a root beer cake with vanilla frosting would work, nor a vanilla cake with rootbeer frosting…
Then I thought about marble cake. I love marble cakes because they are unique and pretty. And hardly anyone makes them anymore.
Perfect! This came out so good. Feel free to adjust the amount of root beer flavoring in the frosting. I think I would add a bit more next time.
Root Beer Float Marble Cake
- 4 eggs
- 2 c sugar
- 2 c flour
- 1 tbs baking powder
- pinch salt
- 1 tsp vanilla
- 2 tsp root beer extract
- 1 c cream
- 1 stick unsalted butter
Beat the eggs until light and thick. They should just about triple in volume and look like this:
Add the sugar and continue to beat.
Mix the dry ingredients together and add to the egg mixture. Add the vanilla.
Heat the cream and butter until butter is melted and hot, but don’t let mixture boil. Add to batter. Beating well while adding.
Remove half of batter and add the root beer extract. Beat it in well.
Spoon batters into greased and floured 9″ pans, alternating between batters. When the batter is all in the pans, swirl a spoon through and it will look something like this:
Bake at 375 for 20-30 minutes, or until done. Let cool in pans for 10 minutes, and remove from pans. Allow to cool completely.
Frosting
- 1/3 cup butter
- 1/4 teaspoon salt
- 2 teaspoons root beer extract
- 3 1/2 cups confectioners sugar
- 3 tablespoons cream
Cream butter, salt, and root beer extract, beating until light and fluffy. Add sugar gradually, beating after each addition. Add cream, beating until smooth.
Adjust amount of cream for desired consistency
Put layers together with the frosting, and use the rest to frost top and sides of the cake. serves 10-12

My husband loves root beer floats. What a great recipe, I’ll have to make it for his birthday this August. Thanks!
Great recipe!! Thanks for posting this. I have never quite seen something like this before. I’ll have to give it a shot
Obviously, Julie, you are no where near a rootbeer float addict …you could never wait that long…
Let me know how you like it Kevin.
Wow! I had no idea there was root beer extract. What a fun idea.
I had the worst time explaining the concept of making a marbled cake when one child asked if they could make a cinnamon swirl cake..end result…No swirl. LOL Then it is just a cinnamon cake. That’s just wrong.
Very creative, Marye!
Marble cake is on my high list of things to make. This looks great Marye!
I too never heard of root beer extract!
Ginger and Pix- root beer extract is what you use to make homemade root beer. At my store it is next to the other extracts.
Wonderful recipe. I can’t wait to get some root beer extract! I’m a real cake lover.
Sherry, thank you! I enjoyed your blog very much!
I tried this out today, and it turned out great. Everyone who has tried it has said it is unusual, but very good.
Sarah, thank you for letting me know! I thought it was yummy..
Glad it worked for you.
I really want to try this recipe but have no idea where to get root beer extract…at a home brewing type store? The one I called seems to only have gallon jugs.
Liz- I got this at our local Tom Thumb/Safeway in with the other extracts in a 4 oz bottle.
This Root Beer Marble cake looked spectacular. The marbling effect was the prettiest that I have ever seen. My husband said that it tasted just like those root beer candies that are in the shape of a barrel. Everyone did say it was fun to have but once was enough.
Tamara I am glad you liked it..
It is an unusual cake.
