I am making Petit Fours, and I am wondering should I crumb coat them before applying the poured fondant? I'm worried that the butter cream might melt. But I don't want crumbs on the cake.

I always apply a thin layer of butter cream to my sheet cake, put in freezer for about an hour, then cut my pt4's (1 1/2 x 1 1/2) put them side by side on grid and pour my pt4 icing. BC does not melt off. I'm one of the few that love doing pt4's. Do them often.

Excellent Debbie! Thank you
