Expert tips:

  • Room temperature ingredients – Make sure to have all your refrigerated ingredients – not just the butter – at room temperature before you start, by removing them from the fridge an hour in advance. Having the eggs, milk, and sour cream at room temperature will help bring the batter together without it separating.
  • Cake flour – Using store-bought cake flour really makes a difference with this recipe. However, if you are in a pinch, mix 2 & 1/4 cups AP flour with 1/4 cup cornstarch.
  • Decorating the cake – Use the back of a tablespoon to spread the buttercream frosting on the cake. Twist your wrist to create swirls and just top with sprinkles along the edges to highlight the beauty of the buttercream, especially if you are using vanilla beans.

FAQ:

What is a sheet cake?

A sheet cake is a cake baked in a large shallow rectangular pan, such as a jelly roll pan. So a single layer 9×13″ cake is technically a quarter sheet cake but is often referred to as a sheet cake, nonetheless.

How do I substitute vanilla bean for vanilla paste or extract?

One vanilla bean is equivalent to 2 teaspoons of pure vanilla bean paste or pure vanilla extract.

How to store vanilla sheet cake:

Tightly cover and store in the refrigerator for up to 5 days. Bring to room temperature by letting it sit out on the counter for 1 hour before serving.

How to freeze vanilla sheet cake:

The cake can be frozen with or without the frosting. Tightly wrap the cake in a double layer of saran wrap and store in the freezer for up to 3 hours. Thaw overnight in the fridge and bring to room temperature before serving.
