"I was about to suggest she goes and buys one from walmart then but she said her husband wants a cake from me."
This is in her first post...the husband wanted her cake...
Those are probably factory made from Wilton...best bet to make yourself with buttercream are these tips depending on size flower you want. I agree modeling chocolate or fondant you could create these...
It will be fine wrapped in plastic...just leave the plastic on when its thawing...is the ears are fondant can you remove those easily and put back on next Sunday? Good luck! Hope your little girl feels better!
I haven't, I would think it would take a lot of dye to try to achieve and change the whole texture...maybe use a peanut butter filling to get the peanut butter flavor? Good luck...
