Two things I need to mention here. First, I’m sorry for all the strawberry recipes. Its just that time of year and, well… it’s just that time of year. Second, I don’t often throw around words like “best,” but this time I mean it. You know how much I love the ease of a sheet cake and here we have my most favorite strawberry version. I’ve been tweaking this recipe for some time until I got it right where I want it. The cake is light and fluffy, but super moist and the icing is the perfect sweetness. I just love this cake. I mean LOVE it. Like it ate two pieces while trying to photograph it. There’s no shame. It’s that good. Now go make it so you can see what I’m talking about. 
Best Strawberry Sheet Cake
Prep time
Cook time
Total time
Serves: 10 to 12 servings
Ingredients
For the cake:
- 1 (16-ounce) container fresh strawberries
- 1 (16.5-ounce) package white cake mix
- 3 eggs
- ¾ cup vegetable oil
- 1 (3-ounce) package strawberry flavored instant gelatin (I used Jell-O)
For the icing:
- ¼ cup butter (1/2 stick), room temperature
- 4 ounces cream cheese
- 1½ teaspoons vanilla extract
- 3 cups powdered sugar
- 1 teaspoon strawberry flavored instant gelatin (reserved from cake)
- 2 tablespoons strawberry puree
Instructions
For the cake:
- Wash and hull the strawberries and gently puree them in a food processor, blender, or with a hand (stick) blender. You want them to be good and chopped up but not all liquid. You will need 1 cup of this puree for the cake and 2 tablespoons for the icing. This should make more puree than you need. However, if it doesn't, pour the puree into a measuring cup and add just enough water to make 1 cup plus 2 tablespoons.
- Preheat the oven to 350° F and lightly spray a 9X13 baking pan (or dish) with nonstick cooking spray. In a large bowl with a hand mixer (or in a stand mixer), mix together the cake mix, eggs, and vegetable oil until well combined. Open the gelatin and measure out 1 teaspoon into a small bowl and set aside for use in the icing. Pour the remainder of the gelatin and 1 cup of the strawberry puree into the batter and mix well.
- Pour the mix into the prepared pan and spread evenly. Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Allow to cool completely before icing.
For the icing:
- In a large bowl with a hand mixer (or in a stand mixer) cream together the butter and cream cheese until well combined and all lumps are gone. Add the vanilla and mix well. Slowly add 3 cups of the powdered sugar separately mixing well after each addition. Add 2 tablespoons of the strawberry puree and the reserved 1 teaspoon of strawberry flavored gelatin and mix well. Add additional powdered sugar if the icing is too thin. Spread over the cooled cake. Store in the refrigerator.

Feeding people makes me happy. It’s just about as plain and simple as that. There are few things in this world that I delight more in than my family and friends gathered around my table enjoying a meal. Pull up a chair and join us! 
Yum!!!
My favorite cake is caramel Cake immediately followed by Strawberry Cake!! I can’t wait to try your recipe for Easter!! Thank you!!
Hope it turns out great for you!
I’m assuming that’s 3/4 “cup” vegetable oil? I plan to make this tonight!
It is! 🙂
It says 3/4 CP of oil
Hi Stacey! Thank you so much for the strawberry sheet cake recipe! I’m leaning more to sheet cakes as they are so much easier to prepare! Have a wonderful Easter! Blessings from Bama!
I know, I’m the same way. I love a good shortcut! I sure hope you’ll enjoy this one!
Can you use frozen strawberries and if so, chop frozen or thaw first?
Thanks for your help as I am anxious to make this and have plenty of berries in the freezer.
Sure! You’ll just need to thaw them and puree them ensuring you have 1 cup plus 2 tablespoons of puree for the recipe.
Hi Stacey, thanks for the recipe it looks so tasty. I will be buying a white box of cake mix so I can make this cake. Sheet cakes are so easy. Take care and God bless
I sure hope you’ll enjoy it as much as we do!
Was just wondering if the size of the pan is wrong usually a sheet cake is in a 11 x 15 pan
Actually there are three standard sizes of “sheet” cake pans – whole, half, and quarter. This would be closest to a quarter sheet, but the recipe is correct at 9×13. Regardless of the sizes of the pans, they are each referred to as sheet cakes because they are made in one layer verses multiple layers like a stacked cake.
The larger is a jelly roll pan
Nope, it is a 1/4 sheet.
Never be sorry for strawberry recipes! This sheet cake looks fantastic! 🙂
Lol! Thanks Beth!
This was an AWESOME cake. I say was cause I keep nibbling along with the rest of the gang. Made it for Easter Feast it make a beautiful cake that smells great. I have tried other fresh strawberry cakes and have been so disappointed. I am thankful for your diligence in tweeking till it is the “Best”. Keep on keeping on, your on the right path.
Thanks so much! I’m so glad you enjoyed it!!
Hi Stacey…I’m a loyal follower of your blog. I love your stories and your recipes.
Just thought I’d tell you that I am making your strawberry cake for my Mom’s 97th
birthday tomorrow. Strawberry is always her favorite and I know she will love this.
Thanks for all the words of wisdom and the great recipes.
HAPPY SPRING!!!
On my goodness! What an honor! Please tell your mother Happy Birthday for me! I sure hope y’all will enjoy!!!
Now I know what my ladies Sunday School class will have for next Sunday morning. Gets hard trying to think of something different every Sunday. Love these recipe, like to take them and change up the flavored and make them unique.. White cake mix. Orange jello, can chopped mandrin oranges. Possibilities are endless. Thank you for getting my imagination working
Great ideas, Betty! I sure hope y’all enjoy!!
Can you tell me what strawberry purée is that is called for in the icing? I can’t wait to make this. My strawberry layered cakes always slip and slide!
You actually make the strawberry puree in the recipe. 🙂
This cake is absolutely divine. Made it exactly as the recipe called for. It was perfect and one of the best cakes I have ever made. Delicious!!!!!!
That’s the best compliment I could get, Jennifer! So glad you enjoyed it!!
Hi Stacey, Happy Spring……….Well you just made my day once again. About 40 years ago when I was working at a club there was a waitress at that time already in her late 70’s and of course everyone’s favorite. She started a tradition of making me a strawberry layered cake with strawberry icing all made from scratch. She even made the cake for me when I went away to college and one year I was in the hospital on my birthday and she still would make sure I got my cake. She never shared her recipes though. I figured out the icing but I could never figure how she made the cake. I tried so many different ways but it was never the same. I never thought of using strawberry gelatin in the cake or the icing. but I’m guessing that is how she made it. I can’t wait to make it. Millie was her name and she was a wonderful women. She passed away about 30 years ago and I think of her often, especially on my birthday’s. Thank you for sharing your recipe with all of us. I love your passion for cooking. I love that you go for the down home flavors and comfort food.
Thanks so much, Cheryl! I sure hope you enjoy the cake!
Stacy, I just received your cookbook for mother’s day and really,
really like it. Looking forward to your next cookbook. Hope it
comes out soon!! Love the recipes and trying one of the recipes
tonight.
What a sweet gift! So glad you’re enjoying it!
Hi Stacey just wondering can you bake this in a bundt pan?
I’ve never made it that way, but can’t see why it wouldn’t work. Are you planning to use the same icing?
My daughter requested a strawberry cake for her 4th birthday party – this looks perfect, thank you!
I sure hope she’ll enjoy it! Happy Birthday!!
It was a HUGE hit today, thanks again. Doubled the recipe and baked it in a half sheet cake pan.
Awesome, Laura! I’m so glad it turned out well for you!
Wow! I was looking for something like this. But can I use something other than vegetable oil? Also, can I use flour in place of the box cake mix?
Thanks Man!
You are welcome to use melted butter in place of the oil, I would just add a tablespoon or two to account for the solids in the butter. When it comes to changing the cake mix to flour, that’ll require a bunch of other changes and being that I’ve not tested it that way, I’d hate to recommend it.
I made this last Friday to celebrate on Saturday, people loved it!! I used a different icing, but the cake itself was the hit and it was so, so easy! It was very moist and flavorful. TY!
Awesome! So glad everyone enjoyed it!!
Can I use frozen strawberries that are in syrup? Thanks
No, this one really needs to be made with fresh berries. Otherwise it would be too sweet.
Hi!
This looks great, however I want to make a layered cake. How would I go about doing that with this amount of batter- would it turn out the same if I just adjust the baking time and split it between two round cake pans?
Thanks!
Honestly, I’ve never done a layer cake with this recipe.
I made this for Easter and it was wonderful! I’ll make this for every special occasion this summer. Thank you
Awesome! So glad to hear y’all enjoyed it!
My boss is not a fan of chocolate, so I am looking forward to making this and bringing her a piece. Sounds delicious!
Hope she’ll love it!!
Just wanted to let you know that I made this cake for my daughters 4th birthday and everyone LOVED it. Made it exactly as stated, but put cut strawberries on top for decoration. Thank you!
Awesome, Jessica! Nothing makes me happier!
What brand of white cake mix did you use? I would like to make this for my daughter’s birthday. Thank you!
I usually just use what’s on sale. I often use the Pillsbury Moist Supreme, though.
This recipe looks great! could I make them into cupcakes?
Absolutely!
I made this cake last year for a family get-together—–YUM!!! It was soooo good. I think it disappeared faster than any cake I’d ever made. Just looking at the picture makes me want to make it again.
That’s quite the compliment, Beverly! So glad you looked like a rock star!!
This looks so good!! BCould I use pilsbury strawberry box mix, it’s all I have?
Sure! Even more strawberry flavor!
No milk (or water) for this recipe? I’ve seen several very similar strawberry cake recipes using a white cake mix & pureed strawberries, but they all also call for some milk or water. Thanks!
Nope. The moisture from the puree and the oil is all you need.
I was just at a luncheon for the Mayor and one of the deserts was a strawberry cake. It was like yours so I am going to make it tomorrow I hope. And I will let you know, it sounds delish.
I sure hope you’ll enjoy it!!
Can I use a yellow cake mix instead of a white cake mix?
Sure!
Can this be made on a quarter sheet pan?
A quarter sheet is 13″x9″.
Can frozen (thawed) strawberries be substituted for the fresh ones?
Yes I made it that way and it was perfect
They sure can. 🙂
What a perfect spring cake! My daughter and I absolutely love strawberries! I think this will be a perfect cake for her and I to make together. Thank you so much for this! I can’t wait to taste it!
I sure hope y’all will enjoy it!! It’s one of my favorites!
Can I make this a day ahead of time? If so, should I refrigerate it or can I leave it on the counter for a day?
Absolutely! I usually keep it refrigerated and take it out about an hour before serving.
Do you put aluminum foil over the cake when it’s refrigerated? I tried this and it kind of stuck to the frosting …. so I had to reapply it. I put a few tooth picks in the cake and put the foil back on to hold the foil over the cake so it wouldn’t touch the cake. Do you do something else? Did I do something wrong? Or do you have some other suggestions for me? Thanks! 🙂
Tess, I typically use a pan that has a plastic lid. But I think you did perfectly with the toothpicks. Great idea!
Made for Mother’s Day. Was a big hit. Everyone asking what I’m baking next. Thanks
So glad everyone enjoyed it!!
My 6 year old son always asks for a strawberry cake for his birthday-and I love that he asks even though it’s usually a pink cake! He knows what he likes! I used your recipe this year and we all loved it. The frosting was wonderful! This is my new favorite strawberry cake recipe, thanks for sharing!
I couldn’t ask for a better compliment!!
Could I do the same thing with other fruit. I want to make a rainbow cake with food coloring. I also each layer to be a different flavor. I want the flavors to be pineapple, lemon, strawberry, apple .lime, orange. and cranberry . would it be possible to change the fruit and jello to match.
That’s quite ambitious! Soft, juicy fruits like strawberries and pineapple should work just fine. I’m not sure that apples and cranberries would work, though.
This is THE best cake! The first time I made it was Father’s Day and both my husband and my son ate 2 pieces – a piece!! The cake is super moist and the frosting has got the best flavor. I have made at least 6 times and have one in the frig to take to Tennessee tomorrow!!
Nothing makes me happier than comments like this one! So glad y’all are enjoy the recipe, Carolyn!
