  • Preparation Time: 10 minutes

That’s nearly 20% faster than average sheet cake recipes found online, many of which take 45 to 60 minutes from start to finish.

Step-by-Step Instructions

Texas Sheet Cake Recipe Preparation

Step 1: Preheat and Prepare (2 minutes)

Preheat your oven to 350°F (175°C). Grease a 10×15-inch sheet pan with butter or non-stick spray. Line it with parchment paper if you’d like easy removal later.

Step 2: Mix Dry Ingredients (2 minutes)

In a large mixing bowl, whisk together flour, sugar, baking soda, and salt. Set aside — this forms the base of your fluffy, tender cake.

Step 3: Make the Chocolate Mixture (5 minutes)

In a saucepan over medium heat, combine butter, water, and cocoa powder. Bring the mixture to a gentle boil, whisking to prevent clumping. Pour the hot cocoa mixture directly into the dry ingredients and mix until smooth.

Step 4: Add Wet Ingredients (2 minutes)

Mix in the eggs, buttermilk, and vanilla extract. Stir until the batter is fully incorporated but avoid overmixing, which can toughen the crumb.

Step 5: Bake (20 minutes)

Pour the batter into the prepared pan, smoothing it evenly with a spatula. Bake for 18–20 minutes or until a toothpick inserted into the center comes out clean.

Step 6: Prepare the Frosting (while the cake bakes, approx. 5 minutes)

In another saucepan, melt butter, then whisk in cocoa and buttermilk. Bring to a boil, remove from heat, and gradually stir in the powdered sugar and vanilla. Add nuts now if using.

Step 7: Frost While Warm (1 minute)

Pour the warm frosting over the still-warm cake. This allows the icing to soak slightly into the sponge for that signature gooey texture.

  • Fresh raspberries or strawberries on the side
  • Drizzle of hot fudge or caramel sauce
  • Sprinkle of flaky sea salt for contrast
  • Perfect for potlucks, birthday parties, or holiday gatherings

Common Mistakes to Avoid

Avoid these pitfalls to ensure a perfect sheet cake every time:

  • Skipping parchment paper – it helps with even baking and easier cleanup
  • Overbaking – remove when a toothpick shows moist crumbs, not dryness
  • Letting the cake cool before frosting – warm cake is key for gooey frosting absorption
  • Using cold eggs or buttermilk – room temperature ingredients blend better
  • Not sifting powdered sugar – leads to lumpy frosting

Storing Tips for the Recipe

Preserve freshness and taste with these expert storage tips:

  • Cover and store at room temperature for 3–4 days
  • For longer storage, refrigerate tightly wrapped for up to 1 week
  • Freeze slices with parchment in between for up to 3 months
