Easy Strawberry Soda Cake
Fluffy, flavorful, fruity strawberry sheet cake topped with a creamy strawberry-infused buttercream frosting — would you believe that all you need is a box of cake mix and a can of Sprite to get started?!
Boxed cake mixes are a staple in my baking cupboard. We use them for so many different things – from making a cheater cobbler to cake mix cookies – and today we’re sharing how we combine a boxed cake mix and a can of soda for a fluffy and EASY sheet cake recipe!
This is such a fun cake mix hack to make with the kids. My daughter loved watching the cake mix bubble up and get all frothy before we whipped it into a gorgeous pink batter.
Literally ANYONE can make this cake — that’s why it’s the perfect starter recipe to make with the kids!

Why Put Sprite in a Cake?
A box cake mix usually requires water, butter or oil, and eggs to bake. But did you know that adding a can of soda will take the place of those three ingredients?
Sprite is a liquid, so it will ensure that the dry powder mix turns into a usable cake batter. The cake mix contains leavening agents that ensure the cake rises as it should.
Plus, the Sprite adds a touch of lemon while also giving the cake a really light, fluffy texture. If you want a denser cake texture, you can always add an egg or two, but this is not required.

Tip: this cake turns out very light and fluffy, with a bit of a crumbly texture without the addition of the eggs. Add 2 eggs to the cake batter for a sturdier crumb, if desired.

How to Make Strawberry Cake with Soda
Preheat oven to 350F. Grease a 9″ x 11″ casserole dish and set aside.
In a large bowl, beat together the white cake mix and Sprite for 2 minutes.
Bake for 25-30 minutes, until an inserted toothpick comes out clean.
Allow the cake to cool completely before frosting.
In a large bowl, beat together the butter and powdered icing sugar for 2 minutes, then add the strawberry extract and optional food dye. Beat to incorporate, then add the milk as needed.
Use an offset spatula to spread most of the frosting on the cooled cake.
Scoop the remaining frosting into a piping bag fit with a large star tip and place 12 evenly spaced starburst dollops along the cake to indicate each “serving.”
Place a halved strawberry on top of each dollop of frosting.
Frequently Asked Questions
Can I Make this into a Layer Cake Instead?
I prefer this recipe as a sheet cake because it’s so light and fluffy, but if you want to make it into a layer cake be sure to add the optional eggs to make the cake a bit more firm.
How Do I Make My Own Strawberry Extract?
Place 1 cup of strawberry juice or strawberry soda in a saucepan and heat over high until bubbling. Turn down the heat to medium and continue to reduce the liquid until just 1/4 cup of liquid remains. Allow to cool completely before using in the frosting.
You can also use a combination of strawberries, water and sugar, but that involves getting out the strainer and can sometimes not have as much flavor as the soda or juice versions – so stick with those for best results.
Can You Use Canned Frosting to Save Time?
Of course! But if you have time, I definitely encourage you to give our super simple strawberry buttercream a try – it tastes worlds better than anything from a can and is super simple to make with strawberry extract. (And while we get a lot of use out of our strawberry extract, if you don’t want to splurge on a bottle you can boil down a bit of strawberry soda or strawberry juice to make your own extract.)
