Yellow Texas sheet cake is a classic American dessert that swaps the usual chocolate for a tender, buttery yellow crumb, soaked in a warm, glossy buttermilk-pecan frosting. It’s baked in a half-sheet pan, so it’s thin, moist, and perfect for feeding a crowd. The hot frosting seeps into the cake as it sets, creating a rich, caramel-like topping that contrasts beautifully with the light, fluffy base.
Ingredients
- 2 cups (250 g) all-purpose flour
- 2 cups (400 g) granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup (2 sticks, 226 g) unsalted butter
- 1 cup (240 ml) water
- 2 large eggs, at room temperature
- 1/2 cup (120 ml) buttermilk, at room temperature
- 1 teaspoon vanilla extract
- For the frosting:
- 1/2 cup (1 stick, 113 g) unsalted butter
- 1/4 cup (60 ml) buttermilk
- 3 cups (360 g) powdered sugar, sifted
- 1 teaspoon vanilla extract
- 1 cup (120 g) chopped pecans (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 13×18-inch (33×46 cm) half-sheet pan with butter or nonstick spray.
- In a large bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
- In a medium saucepan, melt 1 cup (2 sticks) of butter with 1 cup of water over medium heat. Bring to a gentle boil, then remove from heat immediately.
- Pour the hot butter mixture into the dry ingredients and stir until just combined. The batter will be thin and slightly lumpy—that’s fine.
- In a small bowl, beat the eggs lightly, then add the buttermilk and 1 teaspoon vanilla. Stir into the batter until fully incorporated.
- Pour the batter into the prepared pan and spread evenly. Bake for 20–25 minutes, until the top is golden and a toothpick inserted in the center comes out clean.
- While the cake bakes, make the frosting. In a clean saucepan, melt 1/2 cup (1 stick) butter with 1/4 cup buttermilk over medium heat. Bring to a simmer, then remove from heat.
- Whisk in the powdered sugar and 1 teaspoon vanilla until smooth. Stir in the chopped pecans if using.
- As soon as the cake comes out of the oven, pour the hot frosting over the top and spread it evenly with a spatula. The frosting will be thin and will soak into the cake slightly.
- Let the cake cool completely in the pan on a wire rack, about 45 minutes. The frosting will set as it cools. Slice into squares and serve.
Tips
- Buttermilk substitute: If you don’t have buttermilk, mix 1 tablespoon lemon juice or white vinegar with enough milk to make 1 cup. Let it sit for 5 minutes before using. This works for both the batter and the frosting.
- Don’t overmix: Stir the batter just until the flour disappears. Overmixing develops gluten, which makes the cake tough instead of tender.
- Frost while hot: The frosting must be poured over the cake while the cake is still warm—otherwise it won’t spread evenly or soak in properly. Work quickly but carefully.
- Pan size matters: A half-sheet pan (13×18 inches) is essential. If you use a smaller pan, the cake will be thicker and need more baking time; if you use a larger one, it may be too thin and dry out.
Serving Suggestions
Serve this cake at room temperature, cut into generous squares. It’s perfect for potlucks, birthdays, or any gathering where you need a dessert that feeds a crowd. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream to balance the sweet, nutty frosting. A glass of cold milk or a cup of black coffee also complements the buttery flavor beautifully.
Variations
- Chocolate twist: Swap 1/4 cup (30 g) of the flour for 1/4 cup (25 g) unsweetened cocoa powder to make a chocolate version. Keep the frosting as is or add 2 tablespoons cocoa powder to it for a double-chocolate cake.
- No-pecan version: Omit the pecans entirely for a smooth, nut-free frosting. You can also substitute chopped walnuts or toasted almonds.
- Spice it up: Add 1 teaspoon ground cinnamon and 1/4 teaspoon ground nutmeg to the dry ingredients for a warm, spiced flavor.
- Lemon yellow cake: Replace the vanilla extract in the cake with 1 tablespoon lemon zest and 2 tablespoons lemon juice. Use lemon juice in place of the buttermilk for a bright, citrusy version.
Storage and Reheating
Store leftover cake in an airtight container at room temperature for up to 3 days. The frosting will stay soft and slightly sticky. For longer storage, refrigerate for up to 5 days—bring to room temperature before serving. You can also freeze the unfrosted cake for up to 3 months; wrap it tightly in plastic wrap and foil. Thaw overnight in the fridge, then frost and serve. To reheat individual slices, microwave for 10–15 seconds to soften the frosting, but be careful not to overheat or the cake may become soggy.
Frequently Asked Questions
Can I use a different pan size? Yes, but you’ll need to adjust baking time. A 9×13-inch pan will make a thicker cake that needs 30–35 minutes. A jelly-roll pan (10×15 inches) works too, but bake for 20–25 minutes. Always check with a toothpick.
Why is my frosting grainy? Grainy frosting usually happens when the powdered sugar isn’t sifted or the butter isn’t fully melted. Make sure to sift the sugar and whisk thoroughly until smooth. If it’s still grainy, pass the frosting through a fine-mesh sieve before pouring.
Can I make this cake ahead of time? Absolutely. The cake keeps well at room temperature for 2–3 days. If you’re making it a day ahead, cover it loosely with foil after it cools completely. Do not refrigerate unless you live in a very warm climate, as refrigeration can dry out the cake.
What if my cake sticks to the pan? Grease the pan generously, even if it’s nonstick. You can also line the bottom with parchment paper for extra insurance. If it still sticks, run a knife around the edges and gently lift with a spatula.
Can I use salted butter? Yes, but reduce the added salt in the cake to 1/4 teaspoon and omit the salt in the frosting (the recipe doesn’t call for extra salt anyway). The frosting will have a slightly saltier flavor, which some people enjoy.
Is this cake safe for kids? Yes, it’s a standard baked cake with no raw ingredients. The eggs are fully cooked during baking, so it’s safe for children and pregnant women.
