I seem to be having a problem with my smbc! I made it up yesterday according to the exact instructions of my recipe (same one I have made for months with no problem). I refrigerated it over night and brought it out a few hours ago to bring it to room temp. I stirred it a little bit with my spatula but now it has this unattractive clumpy look, almost curdled. It also seems to be weeping. I know I took care to not over mix, but I am afraid if I try to rewhip it will separate completely! I attempted to ice my first 6in tier and it barely sticks to the cake, sliding around when I pass over with the cake smoother and at points, completely sliding off the cake.
Sorry for the wordiness but idk what to do and would like to know any possible solutions or reasons just in case this happens again in the future!
