Can I Use a Different Type of Cocoa Powder?

Can I Use a Different Type of Cocoa Powder?

Yes, you can! While this recipe calls for Hershey’s Cocoa, you can use any good-quality cocoa powder you prefer. Just make sure it’s unsweetened. Different brands might give slightly different flavors, but the cake will still be delicious.

Can I Make This Cake Ahead of Time?

Absolutely! You can bake the cake layers up to two days in advance. Once they’ve cooled, wrap them tightly in plastic wrap and store at room temperature. You can also make the icing ahead of time and keep it in the fridge. Let it come to room temperature and stir it well before frosting the cake.

Can I Freeze the Cake?

Yes, you can freeze it! To freeze the cake, wrap the cooled, unfrosted layers tightly in plastic wrap, then in aluminum foil. They can be frozen for up to three months. Thaw them overnight in the fridge before frosting. If you want to freeze the frosted cake, flash freeze it uncovered for about an hour to set the icing, then wrap it tightly and return it to the freezer.
