Perfect for feeding a crowd, this Strawberry Sheet Cake made with fresh pureed strawberries is especially tasty!
I love fresh strawberry desserts when berries are in season. If I’m not making this Strawberry Sheet Cake, I’m whipping up Strawberry Shortcakes or Strawberry Cupcakes!
Strawberry Texas Sheet Cake
Some of my most popular recipes on the blog are my White Texas Sheet Cake and classic Texas Sheet Cake!
Yes, they’re delicious, but we also like them because they are simple and an easy way to feed a lot of people. ๐
This Strawberry Sheet Cake is a new favorite version! It’s filled with so much strawberry flavor because it uses both fresh pureed strawberries, plus a package of strawberry jello. Not to mention the smooth and creamy strawberry frosting on top – it’s amazing!!
If you love strawberries and easy cakes, this is the recipe to try!! It’s one of our favorite strawberry cake recipes!
Recipe for Strawberry Sheet Cake
First and foremost, you will NOT be using the instructions or ingredients that are listed on the box of cake mix or jello. Only use the white cake mix according to the instructions in my recipe!
PREP. Preheat the oven to 350ยฐF.
PUREE. Add the strawberries to a blender or food processor and blend. You will need 1 cup of pureed strawberries for the cake batter, plus an additional ยผ cup of pureed strawberries for the frosting. Set aside.
BATTER. In a large mixing bowl, whisk the cake mix, large eggs, and oil until well combined. Add JELL-O powder and 1 cup strawberry puree to the flour mixture. Mix well.
BAKE. Pour the batter into a greased 9×13 prepared pan. Bake for 30 minutes. Let the cake cool.
Make cupcakes: Simply divide the batter into about 24 cupcake tins. Bake at 350ยฐF for 15 to 20 minutes. Watch carefully as bake times vary from oven to oven. Cool and frost.
Strawberry Cream Cheese Frosting
This strawberry frosting is the PERFECT partner for Strawberry Sheet Cake!
CREAM. While the cake is cooling, make the strawberry frosting. Cream together the butter and cream cheese. Add vanilla, powdered sugar, and strawberry puree, then mix until smooth and well combined.
FROST. Once the cake is completely cooled, spread the frosting on the cake. Frosting may be made in advance. Store in a container in the fridge for one day before frosting. Give it a good mix before spreading it on the cake or cupcakes.
Recipe Tips + Variations
Frozen strawberries. Use plain frozen strawberries instead of fresh. Simply allow the berries to thaw a bit, then puree them in the blender. Be careful not to thaw them all the way otherwise they will be too wet and mushy.
Cake mix. The box cake mixes at my grocery store are 15.25 ounces. Only use the dry cake mix powder and follow the sheet cake recipe, not the recipe listed on the box.
Strawberry gelatin. I used the Jell-O brand, but a generic 3 oz package of strawberry jello will work. Use only the gelatin powder and follow the cake recipe, not the recipe on the jello box.
Strawberries. A 16-ounce container of fresh strawberries should easily make enough puree: 8 large strawberries weigh approximately 5 ounces and can make ยฝ cup of puree. For this recipe, youโll need 12-13 ounces of strawberries.
Easy clean up. Line the bottom of the pan with parchment paper to help keep the cake from sticking to the pan. Spray the sides with cooking spray.
Serving + Variations
Sheet cake servings is a term used for a single-layer cake. They are often made to serve a large number of people. A full sheet cake is 18โx26โ, a half sheet cake is about 12โx18โ, and a quarter sheet cake is about 9โx13โ.
To create a larger size sheet cake make 2, 3, or 4 batches of this cake. Place them side by side and frost them as if it was one large sheet cake.
- A party serving of cake is 1ยฝโ x 2โ slices
- A wedding serving of cake is 1โ x 2โ slices
Round cake. Divide the batter evenly into two 9โ round cake pans. Reduce the bake time to 20-25 minutes or until a toothpick inserted in the center comes out clean or with a few cooked crumbs.
Variations. To make a raspberry version, use 1ยผ cup pureed raspberries and a box of raspberry gelatin. We do have recipes for other fruity sheet cakes including cherry, lime, and lemon.
Storing Info
STORE leftover cake, covered, in the fridge for 3-4 days.
FREEZE. Flash freeze first by placing the leftovers on a baking pan and sticking them in the freezer until solid. Wrap the pieces of cake with plastic wrap then again with foil. Freeze for 2-3 months. When you’re ready to eat, simply unwrap and allow them to thaw.
Note: If you topped the cake with fresh berries, remove them before storing.

Hi! Just wanted to give my feedback after making this cake twice. The first time I made per directions. It was good, but entirely too sweet. This time, I made some tweaks. I used avocado oil for my oil, used 3 jumbo eggs, and only about a tablespoon of jello mix. (I think that is what made it too sweet the last time for us.) It turned out wonderful and SO moist, without being wet. For the frosting I kept everything the same with the butter and sugar, but I added 1/2 cup of berries, used 2 teaspoons homemade vanilla extract, and 12 oz of cream cheese (a brick and a half.) It made a lot, but it wasnโt super sweet and I put it on thick. Had just a little left over, but it was soooo good this time. Thank you so much!!
You’re welcome!! Thanks for the feedback and sharing what you did. I’m glad you enjoyed the cake!
Iโm thinking the pan should read 13x9x12 the sheet pan size. The 9×13 is a regular pan for cakes. Just trying to help those new at sheet cakes
Thanks for the feedback! We have always made it in a 9×13 and it turns out great. So you could use either!
Iโve made this recipe twice within 30 days. I made it as a layer cake. I DO NOT LIKE STRAWBERRIES but my family loves them. They say this is a delicious cake. Never any leftovers
Can I use a strawberry cake mix instead of white and still add the fresh purรฉed strawberries?
You bet!
I will never understand why cooking times for most recipes that I’ve seen are always wrong, and the food is done in less than half the time that the recipe states. This cake recipe said 350ยฐ for 30 mins in a 13×9. I checked it 23 mins in and it was burnt. Also the frosting was way too sweet.
Thanks for the feedback. Elevation, weather, and temperature can all affect baking time. And every oven is different too. So that could factor into the baking times not being exact. Thanks for giving the recipe a try!
Maybe your oven needs an oven thermometer on the inside, to be sure it’s at the correct temp.
The 9×13 in receipt is a standard cake which would have cooked longer. The receipt should state for a sheet cake 13x9x1/2 it will only take 17 minutes.
Made this for my wifeโs bday last year (2022), turned out amazing! Sheโs requested I make this cake again this year! Yum!
Okay this was beyond delicious! Nothing better than a good sheet cake, thank you so much.
Love the flavor from the fresh berries in the cake, and the frosting is epic! I could eat it just by the spoonful!
Loved this strawberry cake! It was perfect for Valentine’s Day party!
Can I use regular butter instead of unsalted
