Queen's Cake

The dry ingredients (flour and cream of tartar) can be sifted together and stored in an airtight container up to 1 week ahead. However, this cake is best mixed and baked fresh due to the time-sensitive nature of the chemical leavening reaction. The baked cake can be wrapped tightly in plastic wrap and stored at room temperature for up to 2 days before serving.

Store the cooled cake wrapped tightly in plastic wrap or in an airtight container at room temperature for up to 4 days. For longer storage, wrap well and freeze for up to 3 months. Thaw at room temperature while still wrapped to prevent condensation from making the cake soggy.
