Easy Sheet Pan Cake Recipe

If you love strawberries as much as I do, this is a cake recipe that you won’t want to miss! We use a boxed cake mix, which makes this super easy to whip up in 35 minutes from start to finish and the kids love it because they can help with so much of it.

It’s flatter than your average cake because the batter is spread out and baked on a baking sheet rather than a traditional cake pan. So, it’s never heavy and provides enough slices to serve a large crowd. This old-fashioned strawberry sheet cake is the perfect light after-dinner dessert along with a cup of tea or some hot chocolate in the winter. In the summer, it’s definitely a go-to for potlucks and BBQs!

  1. Combine. In a large bowl, combine the cake mix, pudding mix, eggs, oil, water, and sour cream. Mix using an electric mixer on medium speed until combined. Add 1 cup of the strawberry purée and gently combined. Do not overmix.
  2. Bake. Pour into a parchment-lined baking sheet and bake in a preheated 350-degree oven for 20 minutes. Remove and allow the cake to cool before adding any frosting.
  3. Mix. Make the frosting by beating the cream cheese and butter with a hand mixer until smooth and creamy. Add powdered sugar and strawberry purée and mix until combined. Add a pinch of salt or vanilla extract, if desired.
  4. Spread. Using a spatula evenly spread the strawberry frosting overtop the sheet pan dessert.

Use Any Frosting You Like!

Whether you’re adding a plain cream cheese frosting, a strawberry buttercream, or a strawberry cream cheese frosting, wait until your cake cools, then spread it across the entire surface, then add some fresh strawberry slices before you slice and serve!

Cake Tips

Follow these helpful tips to make this strawberry sheet cake even better! Modify this sheet cake for what you have on hand or use these tips to make it easier when baking. These are great ideas for this strawberry cake!

  • Flavors. This can be made with vanilla cake mix or strawberry cake mix if preferred.
  • Size. This cake is quite thin, so if you’re looking for a thicker cake, swap the baking sheet for a 9×13 cake pan. Add 5 minutes to the baking time.
  • Butter. I use salted butter because I like what it adds to the taste, but you can use unsalted butter and then adjust using any added salt to taste.
  • Strawberries. The riper, the sweeter your purée will be. It’s the juices that add all of that delicious strawberry flavor. Just keep in mind, you may want to avoid overly juicy strawberries to top off the cake, otherwise, they may start to bleed into your frosting.

Recipe FAQs

What is the difference between a sheet cake and a regular cake?

The biggest difference between the two pans is the size of the pans. Sheet cake is made with a flatter and more shallow pan but is larger. The regular cake is usually made in a 9×13 baking dish that has a thicker side to it and usually a clear glass pan.

How can I make this into a 9×13 cake pan?

This cake could also be made with strawberry cake mix or vanilla cake mix. You could also bake in a 9×13″ pan if you desire a thicker cake. You will need to add on an additional 5 minutes of bake time.  

Can you add fresh strawberries on top of the cake?

Yes! This is a great way to add more of a special touch and decoration to the cake. I like to add fresh, cut slices of strawberries to each piece as it is served. If you add the strawberries ahead of time, they may bleed through the frosting or even create wet spots on the cake that is not as appealing.

Storing & Freezing

This strawberry cake is perfect for storing leftovers, freezing, or making ahead. Follow these ideas for the best ways to store your cake properly.

  • To store: This cake makes about 24 slices. If you have any leftovers, keep them stored in an airtight container in the fridge for up to 3 days in the fridge.
  • To freeze: You can freeze this cake even with the frosting on! Place any remaining pieces on a baking sheet and flash freeze for 30 minutes. This way, once the frosting has hardened you can transfer it to a freezer-friendly Ziploc or airtight container. Separate the layers with parchment paper that way they won’t clump together.
