• 1 teaspoon baking soda

• 1/2 teaspoon fine sea salt

• 1 cup (240ml) water

• 1 cup (225g) unsalted butter

• 1/3 cup (35g) unsweetened natural cocoa powder (Dutch process gives a deeper color)

• 2 large eggs, room temperature

• 1/2 cup (120ml) buttermilk, room temperature (substitute: 1/2 cup milk + 1½ teaspoons vinegar, mixed and rested 5 minutes)

• 2 teaspoons pure vanilla extract

• 1 teaspoon white vinegar (for extra tenderness)

• Optional: 1 teaspoon instant espresso powder (enhances chocolate flavor)

• Optional: 1 cup (120g) toasted chopped pecans or walnuts (for classic crunch)

For the Warm Chocolate Frosting:

• 1/2 cup (115g) unsalted butter

• 1/4 cup (25g) unsweetened cocoa powder

• 6 tablespoons (90ml) whole milk

• 3¾ cups (420g) powdered sugar, sifted

• 1 teaspoon vanilla extract

• Pinch of salt

• Optional: 1 cup (120g) chopped toasted pecans or walnuts (stirred in at the end)

Essential Equipment:

• 15×10-inch jelly roll pan or 13×18-inch sheet pan

• Parchment paper (optional, for easy removal)

• Mixing bowls

• Whisk and spatula

• Medium saucepan

• Electric mixer (for frosting)

• Wire cooling rack

• Offset spatula (for smooth frosting)

• Plastic disposable knife (for clean cutting)

Step-by-Step Instructions

This detailed process ensures the signature moist crumb and a luscious, crackly frosting. Careful temperature and timing make all the difference.

1. Prep the Pan and Oven

• Preheat oven to 350°F (175°C).

• Grease the jelly roll pan or line with parchment, leaving a slight overhang for easy lifting.

2. Mix Dry Ingredients

• In a large bowl, whisk flour, sugar, baking soda, and salt. Sifting removes lumps and ensures even mixing.

3. Boil Wet Ingredients

• In a saucepan, combine butter, water, and cocoa powder (and espresso powder if using). Bring to a gentle boil over medium heat, stirring constantly until smooth. Remove from heat.

4. Combine Wet and Dry

• Pour hot chocolate mixture over dry ingredients. Stir gently until just combined—don’t overmix.

5. Add Buttermilk, Eggs, and Flavorings

• In a separate bowl, whisk buttermilk, eggs, vanilla, and vinegar. Add to batter and stir until smooth and glossy. Fold in nuts if desired.

6. Bake

• Pour batter into prepared pan and smooth evenly.

• Bake 15–20 minutes, rotating halfway, until cake springs back when touched and a toothpick comes out with a few moist crumbs.

7. Prepare the Frosting

• During the last 5 minutes of baking, melt butter with milk and cocoa in a saucepan over medium heat.

• Remove from heat, whisk in sifted powdered sugar, vanilla, and salt until smooth and pourable. Stir in nuts if using.

8. Frost While Warm

• Pour warm frosting evenly over hot cake right out of the oven. Spread gently to the edges with an offset spatula. The frosting will set into a glossy, crackly layer.

9. Cool and Cut

• Cool in the pan for at least 30 minutes before slicing. Use a disposable plastic knife for the cleanest cuts.

Tips for Perfect Results

A few expert practices guarantee a flawless Texas sheet cake and solve the most common problems.

• Sift Dry Ingredients and Sugar: Sifting powdered sugar into the frosting avoids lumps for a velvety finish.

• Room Temperature Ingredients: Cold eggs and buttermilk can cause the batter to seize—room temp blends best.

• Don’t Overbake: Watch closely in the final minutes; overbaking dries out this thin cake.

• Frost While Hot: This creates the iconic slightly gooey, crackled surface and ensures the frosting seeps into the cake.

• Nut Placement: Toasting pecans or walnuts deepens their flavor; stir in just before pouring frosting for best texture.

• Troubleshooting Cracks: If the frosting sets too quickly, gently smooth with a warm spatula.

• Uniform Slices: Cut with a plastic knife or a very sharp thin-blade knife wiped clean between slices.

Serving Suggestions

Elevate your presentation with these creative and classic serving ideas, perfect for any occasion.

• Traditional Style: Serve squares at room temperature on a large platter—great for gatherings.

• With Ice Cream: Add a scoop of vanilla or cinnamon ice cream to warm slices for a comforting finish.

• Fruit Garnish: Add fresh raspberries or sliced strawberries for a bright, modern contrast.

• Decorative Touch: Sprinkle extra toasted nuts or a pinch of flaky sea salt on top just before serving.

• Layered Dessert: Serve cake squares layered with whipped cream and berries in jars for a picnic-friendly trifle.
