White Texas Sheet Cake

This Texas sheet cake is one of my favorite crowd-friendly desserts because it makes so many servings without requiring extra work in the kitchen. The thin buttery cake stays incredibly soft while the warm frosting melts right into the top, creating that classic nostalgic sheet cake texture people always come back for. We love serving it at holidays, potlucks, and birthdays alongside cozy treats like these strawberry crunch cupcakes with cake mix.

Another reason this white Texas sheet cake recipe works so well for gatherings is how easy it is to transport, slice, and serve to a large group. There’s no layering, stacking, or complicated decorating involved, which makes it perfect for feeding a crowd without spending hours baking. Plus, it’s delicious paired with an iced white chocolate mocha recipe in the middle of the day when the kids are at school ;).

Why The Recipe Works💭

Texture: The thin sheet cake bakes evenly and stays soft and moist thanks to the sour cream, without complicated decorating or layering.

Classic flavor: Warm frosting poured over the cake creates the classic melt-in texture that makes Texas sheet cake so irresistible.

Crowd-friendly: The large pan makes enough servings for potlucks, holidays, birthdays, and easy crowd-friendly desserts.

Items and Substitutions

• All-purpose flour: Sift the flour so that there are no clumps. Gluten-free flour can work, but it will require more liquid ingredients and still be a slightly different texture.
• Sour cream: This helps keep the moisture. Now that yogurt can work in its place, though.
• Powdered sugar: Used for the frosting, again, try to make sure there are no clumps.
• Vanilla: A featured flavor of the cake. The higher quality vanilla you use the more the taste comes through.

Flavors To Try

An easy white Texas sheet cake is a classic for a reason, but there are some ways to adapt the flavor.

• Almond: Swap vanilla extract for almond extract in the cake and frosting for a nutty, almond white sheet cake.
• Top with Nuts: Sprinkle chopped pecans, walnuts, or almonds over the frosting for added crunch.
• Chocolate Drizzle – Drizzle melted white or dark chocolate over the frosted cake for extra indulgence.
• Coconut: A hit in the summer as it gives a tropical taste. Add shredded coconut to the base. f
• Fruit Topping: Garnish with fresh berries or a thin layer of fruit preserves before the frosting sets. This is stunning on my strawberry poke cake with pie filling, too.

Helpful Hints

Here are more helpful tips:

• Don’t Overmix: Stir just until combined to keep the cake light. Overmixed dough makes for tough cakes.
• Work Quickly with the Frosting: It sets fast, so pour and spread it immediately over the warm cake.
• Grease the Pan Well: Use non-stick spray or butter to prevent sticking.
• Store Properly for Freshness: Keep it covered at room temperature for up to 3 days.
• Fridge: If refrigerating, place it in an airtight container or cover the pan tightly with plastic wrap to prevent it from drying out. It will stay fresh for up to one week.
• Freezing: You can freeze individual slices or the whole cake for up to three months, just wrap it well in plastic wrap and aluminum foil.
• Reheating: Let refrigerated slices come to room temperature or microwave them for about 10-15 seconds to soften the frosting and bring back the cake’s fresh-from-the-oven taste.

White Texas Sheet Cake FAQs

Can I use a different pan size for this recipe?

It’s best to use a 10×15-inch jelly roll pan as the recipe is designed for that size. If you use a smaller pan, the cake will be thicker, and it may need more time to bake. If you use a larger pan, the cake may bake faster and be thinner.

Can I use a sugar substitute in this recipe?

While sugar substitutes like stevia or monk fruit can work in some recipes, they may affect the texture and taste of this cake. If you’re following a specific diet like keto, consider making substitutions that are known to work well in baking, like a granular erythritol blend.

How do you keep sheet cake moist?

To keep a sheet cake moist, avoid overbaking it and store it tightly covered once cooled. Pouring the frosting over the warm cake also helps lock in moisture and creates the soft, tender texture Texas sheet cakes are known for.
