I have covered cakes in smbc, and not refrigerated at all. I’ve also covered smbc cakes in fondant, and again, did not refrigerate. A smbc cake is fine for 2-3 days unrefridgerated. Only time I would put my cake in the fridge is because of excessive heat and humidity.
Creativity is God's gift to us. Using our creativity is our gift back to God. Clarky's Cakes 😎
