Soda cakes are the BEST retro cake recipe around when it comes down to saving time. All you need is a box of cake mix and a can of soda pop – the combinations are limitless! This cake recipe uses a box of Devil’s Food Cake Mix and a can of root beer. Slather it with whipped cream and you have an easy dessert that your kids can make. ( and my kids did make this!)

Not only that, it tastes as delicious as a dessert recipe that took a lot longer to make!

Cake Mix and Soda

That’s literally all you need for this recipe, if you don’t want to ice it. We used Cool Whip whipping cream all over our cake, just to have that little something, so this is really just a three ingredient cake! It’s also not a cake that you can be fussy about, the crumb is exceptionally tender and will fall apart, as you can see from my photos. It’s not the least bit dry, simply tender and moist.

This is not a cake that you want to make that is supremely iced and fancy, however it does look very pretty with whipping cream and cherries on the outside. It just won’t slice perfectly, so don’t expect that! Try my new strawberry cake if you want a cake that has pretty slices!

Ingredients Needed:

  • one box devil’s food cake
  • one can of root beer soda
  • whipping cream or light icing

Different Soda Cake Variations

There are so many combinations that you can make a soda cake with, it’s not even funny. Literally just pick a box of cake mix and see what soda pop goes with it! Some pairings you can try are:

  • Strawberry Shortcake – Strawberry Cake Mix and Cream Soda
  • Creamsicle – Orange Soda and White Cake Mix
  • Grape –  Grape soda with white cake mix – try my homemade grape soda cupcakes as well!
  • Ginger Cake– Ginger Spice cake and Ginger Ale
  • Lemon Cake– Lemon cake mix and lemon lime soda

Karlynn’s Recipe Notes

  • This cake has a very tender crumb, so a heavy icing will simply tear it apart. You could even just use a vanilla icing glaze if desired.
  • Real whipping cream will deflate really quickly on this cake, so make it and eat it right away. Cool Whip tends to last a little bit longer.
  • IF you want to use a heavier frosting, freeze the cake, then frost the layers while it’s frozen. Works like a charm!


Don’t forget to try my famous buttercream frosting on your next cake as well, there’s a reason it’s famous!

Have fun guys! This is the perfect easy summertime cake recipe to try with the kids, they will LOVE picking out the combinations. Have fun and enjoy playing around with cake mixes!

Happy Baking!

  1. Greg Gibson says

    Cake was good not sure what happened but had 2 round pans sprayed with no stick but when taken out to cool on rack and flipped over cake stuck on both bottoms. Used butter, cream cheese, vanilla and bakers cocoa for frosting with a cool whip topper. Will try again.5 stars

  2. Jillian says

    I wonder if a Gingerale cake would taste good. Hmmmm. Do I dare? This recipe is so cool and I want to try it but Gingerale is one of the only pop’s I drink! I will report back my findings.5 stars

  3. Curious George says

    Question for you. For your soda pop cake(s) do you add any of the ingredients asked for on the cake box eg. oil, eggs etc. or just the soda?

    • Sara says

      I was about to leave a comment asking the same thing!!

      • Karlynn says
