How to Bake and Frost This Strawberry Sheet Cake

Step 1: Whip Up the Cake Batter

Preheat the oven to 350F. Grab a 9×13-inch baking pan and coat it with cooking spray or parchment paper. In a spacious mixing bowl, combine:
  • Strawberry cake mix
  • Strawberry gelatin mix
  • Pureed strawberries
  • Eggs
  • Vegetable oil
  • Milk
  • Vanilla extract

Blend everything using a mixer on medium speed until the batter looks silky and uniform.

Step 2: Bake to Perfection

Pour the batter into the prepared pan, spreading it evenly. Slide the pan into the preheated oven and bake for 30-35 minutes. Check doneness by inserting a toothpick- it should come out clean. Remove the cake and let it cool completely inside the pan.

Step 3: Create Luscious Strawberry Frosting

In a large bowl, whip the softened butter until it turns creamy. Gradually fold in powdered sugar, alternating with pureed strawberries. Mix on low speed until smooth. Splash in vanilla extract and blend thoroughly. If the frosting seems too thick, splash in milk one tablespoon at a time until you reach a spreadable consistency.

Step 4: Frost with Finesse

Once the cake has cooled entirely, generously spread the strawberry frosting across the top. Use an offset spatula to create a smooth, even layer.

Step 5: Garnish and Serve

Add a final touch with fresh strawberry slices or sprinkles if you’re feeling fancy. Slice into generous squares and enjoy your homemade strawberry sensation!

Tips for Light Cake and Smooth Strawberry Frosting

  • Boost Strawberry Flavor: Add extra strawberry gelatin mix for an intensified fruity taste that makes the cake pop with strawberry goodness.
  • Moisture Magic: Use room temperature ingredients to ensure a smoother batter and prevent overmixing, which can lead to a dense cake texture.
  • Frosting Finesse: Chill the frosting for 10-15 minutes before spreading to achieve a more stable and spreadable consistency that looks professionally finished.
  • Gluten-Free Option: Swap the regular cake mix with a gluten-free alternative and use gluten-free vanilla extract to make this dessert accessible for those with dietary restrictions.
  • Storage Savvy: Store the cake covered in the refrigerator for up to 4 days, allowing the strawberry flavors to meld and intensify over time.

Keep This Sheet Cake Fresh and Ready

  • Store leftover cake in an airtight container in the refrigerator for up to 4 days. Cover the cake loosely with plastic wrap or aluminum foil to prevent drying out.
  • Wrap individual cake slices or the entire cake tightly in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months for best quality.
  • Remove frozen cake from the freezer and let it sit at room temperature for 2-3 hours. Alternatively, defrost overnight in the refrigerator.
  • Warm individual slices in the microwave for 10-15 seconds or in a preheated oven at 300F for 5-7 minutes to restore softness and enhance flavor.

Great Pairings for Strawberry Sheet Cake

  • Pair this sweet strawberry cake with a chilled strawberry iced tea or crisp rosé wine to enhance the fruity flavor profile and refresh the palate.
  • Serve alongside a light vanilla bean ice cream or tangy lemon sorbet to balance the cake's rich sweetness and provide a cool, creamy contrast.
  • Arrange fresh berries like raspberries, blueberries, and blackberries around the cake slice to amplify the strawberry notes and add visual appeal with vibrant colors and natural textures.
  • Top each slice with a dollop of homemade whipped cream infused with a hint of almond extract to introduce a subtle nutty undertone that complements the strawberry's bright, sweet essence.

Flavor Twists for Strawberry Frosted Sheet Cake

  • Gluten-Free Strawberry Delight: Swap regular cake mix with a gluten-free cake mix and use gluten-free gelatin. Replace wheat flour with almond or coconut flour for the pan lining.
  • Vegan Berry Celebration: Use a vegan cake mix, replace eggs with flax eggs or applesauce, and substitute butter with vegan margarine or coconut oil. Choose plant-based milk like almond or oat milk.
  • Low-Sugar Strawberry Option: Select a sugar-free cake mix and gelatin. Use stevia or monk fruit sweetener in the frosting instead of powdered sugar. Reduce overall sugar content while maintaining delicious flavor.
  • Dairy-Free Summer Treat: Substitute milk with coconut or almond milk. Use dairy-free margarine or coconut oil for frosting. Ensure all ingredients are dairy-free certified for sensitive individuals.

Questions About This Strawberry Cake? Start Here

  • What ingredients give this cake its intense strawberry flavor?

The cake combines strawberry cake mix, strawberry gelatin, and pureed fresh strawberries, creating a triple strawberry punch that intensifies the natural fruit flavor throughout the entire dessert.

  • Can I use frozen strawberries instead of fresh ones?

Yes, you can use thawed frozen strawberries for pureeing. Just ensure you drain excess liquid to prevent the cake batter and frosting from becoming too watery.

  • Is this cake suitable for making ahead of time?

Absolutely! This cake can be prepared a day in advance and stored at room temperature, covered. The flavors actually develop and become more pronounced overnight, making it perfect for advance preparation.

  • How do I know when the cake is fully baked?

Use the toothpick test- insert a toothpick into the center of the cake. If it comes out clean with no wet batter, the cake is fully baked. The cake will also have a golden edge and slightly pulled away from the pan sides.

Ingredients

Scale

Main Ingredients:

  • 1 box (15.25 ounces / 432 grams) strawberry cake mix
  • 1 box (3 ounces / 85 grams) strawberry gelatin mix (Jell-O)
  • 4 large eggs
  • 1 cup fresh strawberries, pureed
  • ½ cup vegetable oil

Fresh Ingredients:

  • ½ cup milk
  • 1 teaspoon vanilla extract

Frosting Ingredients:

  • ½ cup unsalted butter, softened
  • 4 cups powdered sugar
  • ¼ cup fresh strawberries, pureed
  • 1 teaspoon vanilla extract
  • 12 tablespoons milk (if needed for consistency)

Instructions

  1. Preheat the oven to 350°F (175°C) and prepare a 9×13-inch baking pan by greasing, flouring, or lining with parchment paper to ensure easy cake removal.
  2. In a spacious mixing bowl, amalgamate the strawberry cake mix, strawberry gelatin powder, pureed strawberries, eggs, vegetable oil, milk, and vanilla extract, whisking vigorously with an electric mixer until the batter achieves a silky, uniform consistency.
  3. Transfer the batter into the prepared pan, meticulously spreading it to create an even layer that will ensure uniform baking.
  4. Position the pan in the preheated oven and bake for 30-35 minutes, monitoring the cake’s progress by inserting a toothpick into the center – it should emerge clean when the cake is perfectly cooked.
  5. After removing the cake from the oven, allow it to cool completely within the pan, which helps maintain its structural integrity and prevents crumbling.
  6. For the frosting, cream the softened butter in a large mixing bowl until it becomes light and fluffy, creating a smooth base for the subsequent ingredients.
  7. Gradually incorporate powdered sugar and pureed strawberries, alternating between the two and mixing on low speed to create a luscious, well-blended frosting.
  8. Enhance the frosting with vanilla extract, mixing thoroughly to distribute the flavor evenly.
  9. If the frosting appears too thick, delicately thin it by adding milk one tablespoon at a time until reaching the desired spreadable consistency.
  10. Once the cake has cooled entirely, generously apply the strawberry frosting across the surface using an offset spatula to achieve a professional, smooth finish.
  11. Optional: Embellish the frosted cake with fresh strawberry slices or decorative sprinkles to add visual appeal and extra flavor.
  12. Slice and serve the delectable strawberry sheet cake, ready to delight dessert enthusiasts.

Notes

  • Customize cake mix by using fresh strawberry puree for more intense fruit flavor and natural sweetness.
  • Ensure ingredients are at room temperature to create smoother, more evenly mixed batter that bakes consistently.
  • Prevent cake from drying out by checking doneness early and avoiding overbaking; toothpick test is crucial for perfect moisture.
  • Adjust frosting thickness by gradually adding milk or powdered sugar to achieve ideal spreadable consistency without becoming runny.
