I have mentioned before on the blog that I am not the biggest cake fan. I think the primary reasons for that are two fold. 1) Most cakes really struggle to get the accurate cake/frosting ratio. 2) I cannot handle a dry cake- and they seem to run rampant in society today.

Cue the celebratory bells! The fact that it feeds a crowd, pleases everyone, and is ridiculously easy to whip together is a mere bonus.

Tips for making this Chocolate Sheet Cake Recipe

• High-Quality Ingredients: Use good-quality unsweetened cocoa powder for a rich and deep chocolate flavor. Dutch-processed cocoa works well. High-quality pure vanilla extract enhances the flavor of the cake as well. Avoid artificial vanilla flavoring for the best taste.
• Don’t have Buttermilk? Buttermilk adds moisture and tenderness to the cake while providing a slight tangy flavor. If you don't have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of milk and letting it sit for a few minutes.
• Proper Mixing: Mix the cake batter until just combined. Overmixing can lead to a denser texture. Scrape down the sides of the bowl to ensure all ingredients are incorporated evenly.
• Sheet Pan: Use a large sheet pan (usually 18x13 inches) with raised edges. Grease and flour the pan or use parchment paper to prevent sticking.

Texas Sheet Cake Frosting Tips:

• Frost While the Cake is Warm: The classic Texas sheet cake frosting is poured over the cake while it's still warm. This allows the frosting to soak into the cake and create a fudgy texture. Be sure to evenly distribute the frosting.
• Texture: The frosting should be smooth and glossy. If it's too thick, add a bit of milk to reach the desired consistency. If it's too thin, you can add more powdered sugar to thicken it.

Storing leftover Texas Chocolate Sheet Cake

• Cover Well: After the cake has cooled, cover it with plastic wrap or aluminum foil to prevent it from drying out.
• Room Temperature: You can store the cake at room temperature for a day or two if it has been properly covered. If storing for longer, consider refrigerating.
• Refrigeration: If your kitchen is warm or you're storing the cake for an extended period, it's best to refrigerate it to maintain freshness.
• Freezing: You can also freeze Texas sheet cake. Wrap it tightly in plastic wrap and aluminum foil, then place it in an airtight container. Thaw it at room temperature before serving.
