Texas Sheet Cake

Texas Sheet Cake is a classic American dessert that's designed to feed a crowd. While subtle variations exist, most people agree on a thin chocolate buttermilk cake that's baked in a jelly roll pan and topped with chocolate icing and toasted pecans. (Interested parties may want to check out the Library of Congress blog for more on its history.) All recipes I encountered forwent any creaming of butter and sugar, instead using a melted butter/boiling water combination to make the batter. The icing is also made with melted butter, typically in a saucepan.

Variations typically concern: the size of the jelly roll pan, whether or not to include cinnamon in the cake crumb, and the exact type of icing. I decided to use the biggest jelly roll pan I owned (18- by 13-inches) because, well, this thing isn't named after Texas for nothing. I also settled on using cinnamon in the crumb because I found it helped round out the otherwise sweet cake. Similarly, I chose to use buttermilk (as opposed to regular milk or just water) in my icing to provide a subtle tang to offset the sweetness. Not that this cake isn't sweet—it most certainly is, but intentionally so.

Why this recipe works:

  • Buttermilk does double duty here: it keeps the thin cake layer moist and it adds a subtle tang to the icing.
  • Making the the icing in the saucepan means it comes together quickly—no beaters involved. It also gives it a pleasing smooth yet fudgy texture.
  • Baking the cake in a jelly roll pan means there's a great cake to icing ratio (well, for those of us who like icing.)
  • Lots of crunchy pecans keep things texturally interesting.

Procedures

  1. 1

    For Cake: Adjust oven rack to middle position and preheat oven to 350°F. Butter and flour jelly roll pan. In a large bowl, whisk together flour, sugar, baking powder, salt, and cinnamon; set aside.

  2. 2

    Melt butter in a medium saucepan over medium high heat. Whisk in cocoa, and when smooth, water. Bring just to a boil, then take off from heat.

  3. 3

    In a small bowl, combine buttermilk, eggs, and vanilla and whisk until combined.

  4. 4

    Pour cocoa mixture over flour mixture and stir with a wooden spoon until incorporated. Stir in egg mixture until well combined. Pour batter into prepared pan and bake until cake begins to pull away from sides of pan and a cake tester inserted into the center comes out clean, about 17 minutes.

  5. 5

    For Icing: Melt butter in a medium sauce pan over medium high heat. Whisk in cocoa powder. Take off heat then add buttermilk, salt, and vanilla. Add 1/2 of the confectioners sugar, whisking until combined. Whisk in water, then remaining confectioners sugar until icing is basically smooth. Pour over warm cake and smooth with a spatula. Top with toasted pecans.
