What is Strawberry Sheet Cake with Cream Cheese Frosting?

Strawberry Sheet Cake with Cream Cheese Frosting is an old-fashioned Southern-style dessert that’s been showing up at potlucks for generations. Traditionally baked in a 9×13-inch pan, this cake is all about simplicity — it’s moist, tender, and infused with real strawberry flavor.

Those natural strawberries create a soft pink hue that’s just begging to be shared on social media. Fourth, it’s adaptable. Want to add a layer of sliced strawberries on top? Go for it. Craving extra tang? Add a touch more cream cheese to the frosting.

And let’s be real — any dessert that makes you feel like you’re at a summer picnic in your grandma’s backyard deserves a permanent spot in your recipe box. For a fun twist, try pairing it with a light summer salad like our panera strawberry poppyseed salad to complete your fruity-themed meal.

Ingredients Needed to Make Strawberry Sheet Cake with Cream Cheese Frosting

• 16 ounces fresh strawberries
• 1 box white cake mix
• 3 large eggs
• ¾ cup oil
• 3 ounces strawberry Jell-O powder (one box)

For the Whipped Strawberry Frosting:

• ¼ cup butter, softened
• 8 ounces cream cheese, softened
• 1 pint heavy cream, cold
• 2 cups powdered sugar
• ¼ cup strawberry puree
• 1 tablespoon vanilla instant pudding mix
• 3 tablespoons strawberry Jell-O powder

Instructions to Make Strawberry Sheet Cake with Cream Cheese Frosting – Step by Step

Step 1: Prepping the Strawberries and the Pan

Start by giving your strawberries a good rinse and removing the stems. Pat them dry — extra water can make your cake batter too thin. Toss two cups of those berries into a food processor and pulse until you have a smooth puree. You’ll need exactly one cup of puree for the cake, so measure that out and set aside the rest for the frosting later. Grease your 9×13-inch baking pan with nonstick spray or line it with parchment paper if you want an easy cleanup. Preheat your oven to 350°F. If your kitchen smells faintly like strawberries already, you’re doing it right.

Step 2: Mixing the Cake Batter

Grab a large mixing bowl and pour in your box of white cake mix, eggs, and oil. Beat the mixture on medium speed for about a minute until smooth. Then add your strawberry Jell-O powder — this gives the cake its signature pink color and that sweet, nostalgic flavor. Pour in your one cup of strawberry puree and blend everything together on low speed until it’s fully incorporated. The batter should look creamy and pink, almost like strawberry milkshake batter. Try not to taste it (though you probably will).

Step 3: Baking the Cake

Pour the batter into your prepared pan, smoothing the top with a spatula so it bakes evenly. Slide it into the preheated oven and bake for about 30–35 minutes, or until a toothpick inserted in the center comes out clean. If you have an instant-read thermometer, the center should register around 200°F. Your kitchen will smell like sweet strawberries by now — that’s your cue to peek through the oven window, not open the door! Once baked, remove the pan and let the cake cool completely. This step is crucial before frosting; otherwise, the warm cake will melt the creamy topping.

Step 4: Preparing the Whipped Strawberry Cream Cheese Frosting

While your cake cools, it’s frosting time. In a large mixing bowl, beat together the softened butter and cream cheese until they’re fluffy and smooth. Add in your powdered sugar and continue to mix on medium speed until everything’s well combined and creamy. Pour in the cold heavy cream and beat until it starts to thicken — you’re looking for soft peaks that hold their shape. Now add your reserved strawberry puree, vanilla pudding mix, and strawberry Jell-O powder. Whip it again until it becomes thick and luxurious. The pudding mix gives the frosting a whipped-cream-meets-cheesecake texture that’s downright addictive.

Step 5: Frosting the Cake

Once your cake has completely cooled, dollop generous scoops of frosting across the top and spread it out evenly with an offset spatula or the back of a spoon. You can swirl it for that homemade bakery look or smooth it out for a clean finish. If you’re feeling fancy, top it with fresh strawberry slices for an Instagram-worthy moment.

Step 6: Chill and Serve

Refrigerate the cake for at least one hour before serving — this helps the frosting firm up and lets all those strawberry flavors meld together beautifully. When you’re ready to serve, cut it into neat squares, and watch everyone’s eyes light up. The cake is moist, the frosting fluffy, and the taste? Pure strawberry bliss.

This step-by-step process might seem detailed, but it’s what makes this dessert foolproof. Even if you’re not a frequent baker, following it will make you feel like you’ve been baking Southern classics for years.

What to Serve with Strawberry Sheet Cake with Cream Cheese Frosting

This cake pairs beautifully with lighter meals or barbecue favorites. Try it after a grilled chicken dinner or a fresh summer salad like our strawberry spinach salad for a refreshing contrast. If you’re hosting a potluck, balance the sweetness with something savory like garlic butter chicken tenders or street corn chicken salad. For beverages, pink lemonade or iced tea complement the flavors perfectly — or go for a cold glass of milk if you’re keeping it classic.

Key Tips for Making Strawberry Sheet Cake with Cream Cheese Frosting

• Use fresh strawberries when possible. Frozen ones work, but make sure to thaw and drain them well first to avoid excess water.
• Always cool your cake completely before frosting. Patience pays off — no melted messes here.
• Room temperature butter and cream cheese are key for smooth, lump-free frosting.
• Want extra strawberry punch? Add a touch more Jell-O powder to your frosting.
• For a neater slice, chill the frosted cake for at least an hour before cutting.

Storage and Reheating Tips for Strawberry Sheet Cake with Cream Cheese Frosting

This cake keeps wonderfully in the fridge. Cover leftovers with plastic wrap or store them in an airtight container for up to a week. For longer storage, freeze unfrosted slices for up to three months. If freezing, wrap each piece individually to prevent freezer burn. When you’re ready to serve, thaw in the fridge overnight and frost fresh. Avoid microwaving — it’ll melt that lovely frosting. For summer gatherings, keep the cake chilled until serving time to prevent the frosting from softening too much. For more dessert storage tips, check out the food safety guidelines at USDA.gov.
