Recipe Highlights: Why This is the Best Texas Sheet Cake
- No mixer required. You only need mixing bowls, a saucepan, and a whisk.
- Buttermilk keeps the cake super tender. It adds moisture and a subtle tang that prevents the cake from drying out.
- Ideal for gatherings. The 9×13 pan yields a crowd-pleasing cake perfect for cookouts, potlucks, and holidays.
Key Ingredients
(Full ingredient amounts are included in the recipe card below.)
- Whole-fat buttermilk — store-bought is best, but you can acidulate whole milk with lemon juice or vinegar if needed.
- Unsweetened cocoa powder — natural cocoa adds chocolate flavor and reacts with baking soda for lift.
- Cinnamon and nutmeg — a touch of warm spice deepens the chocolate flavor.
- Vegetable oil + salted butter — together they lend richness and moisture for a decadent crumb.
- Milk powder — optional, but it adds a subtle creaminess that elevates the flavor.
- Hot coffee — blooming the cocoa in hot coffee intensifies the chocolate profile.
How To Make Texas Sheet Cake
Prep: Preheat the oven to 350°F. Line a 9×13-inch pan with parchment and grease the sides.
Step 1 — Make the chocolate crumble topping: Combine cocoa powder, brown sugar, flour, and melted butter until you have coarse crumbs.
Step 2 — Bake the crumble: Spread the crumble on a baking sheet and bake 8–10 minutes, then cool until crisp.
Step 3 — Whisk dry ingredients: In a large bowl, combine flour, milk powder (if using), brown sugar, granulated sugar, baking soda, baking powder, cinnamon, nutmeg, salt, and espresso powder. Whisk until evenly mixed.
Step 4 — Mix wet ingredients: Whisk together melted butter, oil, cocoa, eggs, buttermilk, and vanilla. Stir the dry mix into the wet, then pour in hot coffee and whisk briefly until smooth.
Step 5 — Bake: Pour batter into the prepared pan and bake 30–35 minutes, until a toothpick comes out with a few moist crumbs.
Step 6 — Make the frosting: Warm butter and heavy cream in a saucepan. Add chocolate chips and stir until melted. Off the heat, whisk in powdered sugar, cocoa, corn syrup (or honey), and vanilla. Fold in chopped pecans.
Step 7 — Assemble: Cool the cake about 20 minutes, pour the warm frosting over the top so it settles into the cake, let it set, then sprinkle the chocolate crumble over the frosting.
Recipe FAQs

The name comes from the cake’s large, sheet-pan format and its generous, comforting portion size.
Yes. Swap whole milk combined with 1 tablespoon lemon juice or vinegar per cup and let it sit 5 minutes. The cake may be slightly less tender without true buttermilk.
Pouring warm frosting lets it melt into the cake’s top layer, creating a glossy finish and adding moisture for that fudgy texture Texas sheet cake is known for.
