Steam-Baked Texas Sheet Cake
Kate Itrich-Williams
December 1, 2021
Moist, chocolatey, and soaked in a sweet, nutty icing, Texas sheet cake is a perfect dessert to perfect in the Anova Precision Oven. The thin cake is typically cooked in a half sheet or jelly roll pan, and all too often can come out dry. By injecting a small amount of steam into the oven, the cake cooks quickly and always turns out moist.
While this style of cake is easy (and fast!) it is important to make sure to measure out all of your ingredients before starting to bake. Both the icing and cake need to be warm in order to ensure that they come together into one cohesive dessert at the end.

Steps
1. Preheat the Oven
Rack
Sous Vide Mode: Off
Steam: Off
Temp: 350°F
Heat: Top, Bottom
2. Prep the Pan
While the oven is heating, generously grease the Anova sheet pan with nonstick oil spray. Dust with flour, then shake off the excess, making sure that the flour gets in all of the grooves of the pan.
3. Toast the Nuts
Rack
When the oven is heated, spread the pecans out on a second small baking sheet. Transfer to the oven and bake until aromatic and lightly browned, 7 minutes. Immediately transfer to a cutting board. Let cool, then coarsely chop.

4. Adjust the Oven for the Cake
Rack
Sous Vide Mode: Off
Steam: 15%
Temp: 350°F
Heat: Top, Bottom
5. Prep Dry and Wet Ingredients
Meanwhile, whisk together the flour, baking soda, and salt together in a small bowl. In a second small bowl, whisk together the buttermilk, egg, egg yolk, and 1 teaspoon vanilla.
6. Make the Batter
Melt the 12 tablespoons of butter in a medium saucepan over medium heat. When the butter is foamy, whisk in the 4 ½ tablespoons cocoa until smooth. Whisk in the granulated sugar until smooth, then whisk in the water. Bring to a simmer, then immediately remove from the heat. Remove from the heat and whisk in the flour mixture until smooth, then gradually whisk in the buttermilk-egg mixture.
7. Bake the Cake
Rack
Pour the batter into the prepared sheet pan and spread it evenly from edge to edge. Transfer to the oven and bake until a toothpick inserted into the center comes out clean, 10 minutes.

8. Make the Icing
While the cake bakes, make the icing: Melt the remaining 4 tablespoons butter in a small saucepan over medium heat. When the butter is foamy, whisk in the remaining ¼ cup cocoa until smooth. Whisk in the milk, corn syrup, and remaining 1 ½ teaspoons vanilla, then remove from the heat. Add the powdered sugar, then whisk (carefully) until smooth.
9. Ice, Cool, and Serve
When the cake comes out of the oven, pour the hot icing over the top, spreading it from edge to edge. It will sink into the cake. Sprinkle the chopped pecans evenly over the top. Let the cake cool completely before slicing and serving.
