How to Make A Smash Cake

Preheat oven to 350ºF. Spray a 4×2-inch round cake pan with baking spray.
In a small mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, and salt.
Whisk together water, oil, vinegar, and vanilla in a cup. Add to dry ingredients and whisk just until combined.
Bake 18 – 20 minutes or until a tester comes out clean. Allow to cool completely before frosting.

Recipe FAQs

Can I make this cake ahead of time?

Yes! You can bake the layers up to 2 days in advance and store them wrapped tightly in plastic wrap at room temperature. The assembled cake can be made 1 day ahead and stored in the refrigerator. Just bring it to room temperature about 1 hour before the smash session.

How do I transport this cake to the party venue?

For safe transport, I recommend chilling the assembled cake for at least 2 hours first. Place it in a cake carrier or box that’s at least 8 inches tall to protect the frosting. Put a non-slip mat under the cake board, and keep the air conditioning running in your car to prevent the buttercream from softening.

What is the best icing for this cake?

I personally love to use a basic cream cheese frosting for these types of cakes, but a buttercream icing will also work very well.

Expert Tips

The cake domes as it bakes, if you want, you can leave the rounded top. Or, use a serrated knife to trim the top flat.
You can decorate the cake as simply as you’d like. I’ve used sprinkles and easy-to-make white chocolate curls on smash cakes.
Bring all refrigerated ingredients to room temperature before starting
Chill cake for 15 minutes between crumb coat and final frosting layer

Easy Decorating Ideas For Beginners

Start with a smooth base coat of white frosting using an offset spatula.

For simple yet effective decoration, try pressing rainbow sprinkles around the bottom edge of the cake or create a basic pattern with them on top.

You can also use a piping bag with a large star tip to make swirls around the top edge – just hold the bag straight up and down, squeeze with consistent pressure, and release gently.

A “1” candle or cake topper adds a perfect finishing touch without requiring advanced decorating skills.
