cake care instructions

Cakes/cupcakes are best decorated at room temperature. If frozen, let the cake/cupcakes and all ingredients thaw to room temperature. This may take a few hours. If you're not quite ready to decorate, store the cake/cupcakes and ingredients in the fridge.

Remove the cake/cupcakes and ingredients from the fridge 1 hour before decorating or serving to bring them to room temperature.

When you're ready to decorate, carefully remove any plastic wrap from around the cake and remove cupcakes from their holders.

Store leftovers in an air-tight container in the fridge for up to 5 days or in the freezer for up to 1 month. To avoid color changes, store the cake/cupcakes out of direct light.

serving tips

Wipe the drool from your face.

Eat the cake/cupcakes at room temperature.

For cakes: Run a large knife in hot water, dry it with a towel, slice the cake. Wipe clean between cutting each slice. Repeat as the knife cools.
