The combination of buttermilk and cocoa powder gives it a unique flavor that is sure to impress.
When preparing this recipe, you might need to pick up a few items that aren't always in your pantry. Buttermilk is essential for the cake's texture and flavor, so make sure to grab some from the dairy section.

How to Store or Freeze This Cake
Allow the Texas sheet cake to cool completely before storing. This ensures that the frosting sets properly and doesn't become sticky or runny.
For short-term storage, cover the cake tightly with plastic wrap or aluminum foil. You can also store it in an airtight container to keep it fresh. This method will keep the cake moist and delicious for up to 3 days at room temperature.
If you prefer to refrigerate the cake, wrap it well in plastic wrap and place it in an airtight container. Refrigeration can extend the cake's freshness for up to a week. Just remember to let it come to room temperature before serving for the best texture and flavor.
To freeze the Texas sheet cake, first ensure it is completely cooled. Cut the cake into individual servings for easier thawing later. Wrap each piece tightly in plastic wrap, then place them in a freezer-safe airtight container or a zip-top freezer bag. This will prevent freezer burn and keep the cake fresh for up to 3 months.
When you're ready to enjoy the frozen cake, remove the desired number of pieces from the freezer. Let them thaw at room temperature for a few hours or overnight in the refrigerator. For a quicker option, you can microwave individual pieces on a low setting for 20-30 seconds, but be cautious not to overheat and dry out the cake.
If you have leftover frosting, store it separately in an airtight container in the refrigerator. It will stay fresh for up to a week. When ready to use, bring it to room temperature and give it a good stir before spreading it on the cake.
For a special touch, you can add a fresh layer of frosting after thawing the cake to enhance its flavor and appearance. This is especially useful if the original frosting has absorbed into the cake during storage.
How to Reheat Leftovers
Preheat your oven to 300°F (150°C). Place the Texas sheet cake on a baking sheet and cover it loosely with aluminum foil to prevent it from drying out. Heat for about 10-15 minutes or until warmed through.
For a quicker method, use the microwave. Place a slice of Texas sheet cake on a microwave-safe plate. Cover it with a damp paper towel to keep it moist. Microwave on medium power for 20-30 seconds, checking to ensure it doesn't overheat.
If you prefer a stovetop method, use a skillet. Heat the skillet over low heat and place a slice of Texas sheet cake in it. Cover with a lid to trap the heat and moisture. Warm for about 5 minutes, flipping halfway through to ensure even heating.
For an air fryer, preheat it to 300°F (150°C). Place the Texas sheet cake in the air fryer basket and heat for about 3-5 minutes. This method can give the cake a slightly crisp edge while keeping the inside moist.
If you have a toaster oven, preheat it to 300°F (150°C). Place the Texas sheet cake on a piece of aluminum foil or a small baking tray. Heat for 10-15 minutes, checking occasionally to ensure it doesn't overheat.
