Frequently Asked Questions
Can I use cake flour instead of all-purpose flour?
Absolutely! Cake flour can yield an even lighter texture, giving your White Sheet Cake a beautiful crumb. Just be cautious with the measurement, as cake flour is more absorbent.
How do I know when my cake is done baking?
The toothpick test is your best friend. Insert a toothpick into the center of the cake; if it comes out clean or with just a few crumbs, the cake is ready!
Can I make this cake ahead of time?
Yes! You can bake the cake a day in advance. Just store it in an airtight container at room temperature, and frost it when you’re ready to serve.
What should I do if my frosting is too thick?
If your frosting is too thick for spreading, add a teaspoon of milk at a time until you reach your desired consistency. Mix well after each addition.
Can I freeze White Sheet Cake?
Definitely! To freeze, wrap it tightly in plastic wrap and then in foil. It can keep well in the freezer for up to three months. Just thaw it in the refrigerator before serving.
