Perfect for feeding a crowd, this Strawberry Sheet Cake made with fresh pureed strawberries is especially tasty!

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. 😉

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 350°F.

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 ¼ 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 350°F 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 ½ cup of puree. For this recipe, you’ll 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 18”x26”, a half sheet cake is about 12”x18”, and a quarter sheet cake is about 9”x13”.

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 1½” x 2” slices
  • A wedding serving of cake is 1” x 2” slices

Round cake. Divide the batter evenly into two 9” 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 1¼ 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.

  1. Your cake looks so good Lily. Thank you. Have a fun day. It’s raining here and is suppose to all day long. Have a good week!

  2. Absolutely adorable!! And your cake looks amazing! I need to give this a try with my daughter 🙂

  3. Sheet cakes are the best and yours looks so pretty! My daughter loves baking with me too, we might need to make this cake very soon.

    1. It is strawberries and a little sugar that have been pureed in like a food processor. If you have a cup of strawberries, add like 1 1/2 tablespoons of sugar and puree in a processor or blender. You could even buy strawberry puree. Hope that helps:)

  4. Do you have any suggestion for adjusting the bake time for the cake to make two circular 8inch cakes?

    Thank you!

    1. The baking time should be the same. If they were the 9in, it be a few min shorter. Let me know how you like! We love it!

    1. You could try adding more powdered sugar 1 tablespoon at a time, until it is as thick as you want. I hope that helps 🙂

    1. I haven’t measured, but it’s just a regular 9×13 pan, so what is an inch & 1/2?? 2??

    Came back to print this …. just had to tell you that this is the best cake!!! my nephew (18 years old) loves it so much that he requested that i make it for his 18th birthday – no bakery cake -only aunt heidi’s homemake strawberry cake would do ! thanks for your hard work in bringing us such great & easy recipes

    1. That’s awesome!! Thank you so much for letting me know that!! Makes me so happy to hear!

  6. 5 stars
    Very FAVORABLE❤️ MoistEst strawberry cake ever and the small amount of cream cheese in the icing make it fabu

      1. 5 stars
        Made this deliciously moist strawberry cake for a family get-together. Was the favorite dessert there, everybody loved it. Hubby now requests it! Have frozen individual pieces and it’s just as good when thawed as it is fresh!

        1. Oh I’m so glad to hear you loved the cake! What a great idea to freeze individual portions for later. Thanks for sharing!

  7. 5 stars
    My hubby & kids would prefer this over chocolate any day! It is the moistest cake ever & that frosting is creamy & delicious!

  8. 5 stars
    Not only is the sheet cake beautiful, It’s so flavorful!!! Perfect for a Shower or any OCCASION really!

  9. Made this for my son’s football dinner with his teammates. They loved it, and begged for more. I will definitely make this again and look forward to trying other flavors.

    1. I’m so happy the football team loved it so much! I love how many different flavors you can try with this cake. Let me know which ones you try. I’d love to hear!

    1. Sure! Simply divide the batter into about 24 cupcake tins. Bake at 350°F for 15 to 20 minutes. Watch carefully as bake times vary from oven to oven. Cool and frost. Enjoy!

    This cake is so delicious made it twice in two weeks for a church gathering and a birthday cook out every one enjoyed it so much great recipe

    1. I’m so happy everyone enjoyed it! This sheet cake has definitely been a crowd pleaser over at my house too. Thank so much for sharing!

  11. 5 stars
    This is AMAZING! I have made this repeatedly for family and friends with no complaints. Moist and decadent!!!

  12. I think I’d like to try this for my daughter’s June birthday party. Would it work well to make two cakes to layer them, and if so, would you also recommend doubling or tripling the icing? It looks delicious!!

    1. You could certainly try that! I haven’t make this cake as a layered cake before, but you could! If you were doubling the recipe to make two cakes, I’d also suggest doubling the frosting. If you do it as a layered cake, you’ll have to let us know how it turns out!

    The frosting ended up melting like I have never seen before. It looked curdled. This at least for me will need to stay in the refrigerator until serving. It was also wetter then most frostings
    Apparently everyone loved it at my mom’s class
    But when she brought it home it was literally sitting in the liquid the frosting had turned to

    1. That’s so strange! I wonder if the frosting got too warm? If it is super runny in the future, you can try adding a bit more powdered sugar to try to thicken it a bit. Storing in the fridge is a good idea too to help the frosting set.

  14. 5 stars
    Love the flavor from the fresh berries in the cake, and the frosting is epic! I could eat it just by the spoonful!

  15. 5 stars
    Made this for my wife’s bday last year (2022), turned out amazing! She’s requested I make this cake again this year! Yum!

  16. 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 350° for 30 mins in a 13×9. I checked it 23 mins in and it was burnt. Also the frosting was way too sweet.

    1. 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!
