I hate when that happens!I made the 5-layer heart cake yesterday. Anyone want the cake tins? Probably won't be using them again.
According to the box, a "regular cake mix" would be right for the tins. So I made up our favorite cake recipe since that makes a "regular cake mix" size cake. Even though I didn't use all the batter, the tins still over-flowed in the oven (thankfully, I had put a baking sheet under them). They were almost impossible to get out of the tins without tearing. All those layers used 1 1/2 recipe of frosting. It took forever to get it all put together.
DH's comment? "You can't tell it's heart shaped unless you lean over it."
Definitely not worth the work or the time.
I have one 9" heart shaped pan. I make a round layer and a heart putting the heart layer on top.
It looks nice and is not a lot of work.
