Ingredients for Creamlike Sheet Cake

For the Cake:

2 ½ cups all-purpose flour
2 ½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup granulated sugar
½ cup unsalted butter, softened
½ cup vegetable oil
Zest of 1 large orange
½ teaspoon vanilla extract
3 large eggs
¾ cup freshly squeezed orange juice
¾ cup buttermilk

For the Frosting:

8 oz cream cheese, softened
½ cup unsalted butter, softened
3 cups powdered sugar
1 ½ teaspoons orange zest
1 teaspoon vanilla extract
2-3 tablespoons heavy cream for consistency

Optional Garnishes:

Orange segments, thinly sliced
Sprinkles or edible glitter for a festive touch

Pro Tip: For a consistent citrus flavor, choose freshly squeezed orange juice and zest for this recipe instead of prepackaged versions.

Step-by-Step Recipe

Step 1 — Preheat and Prepare the Pan

Set the oven to 350°F (175°C). Grease a 9x13-inch sheet pan and line it with parchment paper for easy cake release.

Step 2 — Mix Dry Ingredients

Whisk together the flour, baking powder, baking soda, and salt in a medium bowl. Set aside.

Step 3 — Cream the Butter and Sugar

Using a stand mixer or hand mixer, beat the softened butter, sugar, and orange zest until light and fluffy. This process creates air pockets that will make your cake soft and tender.

Step 4 — Add Wet Ingredients

Beat in the vegetable oil, vanilla extract, and eggs, one at a time, until fully incorporated.

Step 5 — Alternate Dry Ingredients and Liquid

With the mixer on low speed, alternate adding the flour mixture with the orange juice and buttermilk. Begin and end with the dry ingredients to help keep the batter uniform. Mix until just combined.

Step 6 — Bake

Spread the batter evenly into the prepared sheet pan. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Cool completely in the pan on a wire rack.

Step 7 — Make the Frosting

Beat the cream cheese and butter until smooth and creamy. Add the powdered sugar, orange zest, and vanilla extract, mixing until fluffy. Gradually add heavy cream until the frosting reaches your desired spreadable consistency.

Step 8 — Frost and Decorate

Spread the frosting generously over the cooled cake. Use a spatula to create swirling patterns, and garnish with orange slices or sprinkles for added flair.

Step 9 — Slice and Serve

Cut the cake into squares or rectangles. Serve chilled or at room temperature for the best flavor.

Tips for Baking the Perfect Creamlike Sheet Cake

Zest Before Juicing: Always zest your oranges before cutting and juicing them—it’s difficult to zest halves!
Room-Temperature Ingredients: Ensure that your eggs, butter, cream cheese, and buttermilk are at room temperature for a silky smooth batter and frosting.
Chill Before Serving: For a firmer frosting and refreshing flavor contrast, refrigerate the frosted cake for 30 minutes before serving.
