i just used this recipe for a cake for the first time. It was for a friend who asked me to make a babyshower. the taste was awesome.. i did have to play around iwth the amount of powder sugar as i didnt have it weighed. however. i put the leftover in the fridge. I just delivered the cake today and havent heard any feedback yet. My concern is i just noticed how hard it got in the refridgerator. I know its decorators buttercream but i figured it would be great to use inside the cake after reading the great reviews. and since the request was chocolate buttercream. By the time the cake was delivered it was out for 2 hours and im sure it would be out for at least 2 to 3 more hours. PLease someone tell me that this filling softened to a buttercream consistency by the time they probably ate it. Im so nervous now..
It should have reached room temp by the time the cake was served.
