You can experiment with adapting other cake recipes (including sponge cake) for the pan by filling the pan with batter about 1/2 or 2/3[/quote]

I wish I'd seen this web site and this reply in particular...

I had a Tiara Cake Pan from back in the 80s when I was a single parent with two youngin's...hadn't used it in years...since the boxed mixes disappeared.

Recently found the Tiara Cake Pan and filled the it with the entire contents of a Duncan Hines cake mix...OH MY HEAVENS...I had cake mix everywhere...but, as I learned when I began cooking as a single parent, I had the Tiara Pan sitting on a large, Foil covered Pizza Pan, so nothing got into/onto the oven itself!!!

Making the Tiara Cake brought back so many happy memories of me and kids enjoying a Tiara Cake.
