This Texas sheet cake is a delightful dessert that brings a taste of the South to your table. It's a rich, chocolatey cake topped with a smooth, fudgy frosting, perfect for any occasion. The best part? It's incredibly easy to make and serves a crowd, making it ideal for gatherings and celebrations.
When preparing this recipe, you might need to pick up a few items that aren't always in your pantry. Buttermilk is one such ingredient, which adds a tangy flavor and helps with the cake's texture. If you don't have unsweetened cocoa powder, make sure to grab some, as it's essential for both the cake and the frosting. Lastly, ensure you have enough powdered sugar for the frosting to achieve that perfect sweetness and smooth consistency.

Ingredients For Texas Sheet Cake
All-purpose flour: The base of the cake, providing structure and texture.
Sugar: Adds sweetness to the cake and helps with browning.
Water: Used to dissolve the cocoa powder and butter, creating a smooth mixture.
Butter: Adds richness and moisture to the cake and frosting.
Unsweetened cocoa powder: Provides the chocolate flavor for both the cake and frosting.
Buttermilk: Adds tanginess and helps with the cake's texture.
Eggs: Bind the ingredients together and add structure.
Baking soda: Helps the cake rise and become fluffy.

Milk: Used in the frosting to achieve the right consistency.

Technique Tip for This Recipe
When making the frosting for the Texas sheet cake, ensure that the butter is fully melted before adding the cocoa powder and milk. This helps to create a smooth and glossy mixture. Once you bring it to a boil, remove it from the heat immediately to prevent scorching. Gradually adding the powdered sugar while continuously stirring will help achieve a lump-free, silky texture. Pour the frosting over the warm cake to allow it to spread evenly and set perfectly.

- For short-term storage, cover the cake tightly with plastic wrap or aluminum foil. You can also store it in an airtight container to maintain its freshness.
- If you plan to enjoy the cake within a few days, keep it at room temperature. This will keep the cake moist and the frosting smooth.
- For longer storage, place the cake in the refrigerator. This will extend its shelf life up to a week. Make sure it is well-covered to prevent it from drying out.
- To freeze, first cut the cake into individual servings. This makes it easier to thaw only what you need.
- Wrap each piece tightly in plastic wrap, then place them in a freezer-safe bag or container. This double-layer protection helps prevent freezer burn.
- Label the container with the date to keep track of how long it has been stored. The Texas sheet cake can be frozen for up to three months.
- When ready to enjoy, thaw the cake in the refrigerator overnight. This gradual thawing helps maintain the cake's texture and flavor.
- For a quicker option, you can also thaw individual pieces at room temperature for a few hours.
- Once thawed, you can warm the cake slightly in the microwave for a few seconds to bring back its fresh-from-the-oven taste.
How to Reheat Leftovers
Preheat your oven to 300°F (150°C). Place the Texas sheet cake on a baking sheet and cover it with aluminum foil to prevent it from drying out. Heat for about 10-15 minutes or until warmed through.
For a quicker option, use the microwave. Place a slice of the cake on a microwave-safe plate. Cover it with a damp paper towel to retain moisture. Microwave on medium power for 20-30 seconds, checking for warmth. Repeat if necessary.
If you prefer a stovetop method, use a double boiler. Place the cake in a heatproof dish and set it over simmering water. Cover the dish and heat for 5-10 minutes, checking occasionally until warmed through.
For an air fryer, preheat it to 300°F (150°C). Place the cake in the basket and heat for 3-5 minutes. Check for warmth and adjust time as needed.
To retain the frosting's texture, you can use a steam method. Place the cake on a plate and set it over a pot of simmering water. Cover with a lid and steam for about 5 minutes or until warmed through.
