I have covered a cake withe buttercream then fondant and when i woke uo this morning a small area of the fondant has pulled away from the buttercream underneath... leaving a large bubble effect. Any ideas how i can fix this please
if it's an air bubble trapped under your fondant, you can insert a clean sewing pin into the fondant that has puffed up. Try to insert it at an angle so the hole won't be so visible once you remove the pin. After the hole is made, gently ease the air out from under the fondant by pressing the fondant towards the hole. You should be able to smooth it out once all the air has been released.
