Since last year Isabel has asked me for a heart cake that she saw in the same book from which I made Gabriel's train cake. It's basically one normal round cake and one square cake of the same dimensions. The round cake is then cut in half which forms the two rounds of the heart which nesstles agains two sides of the square cake.
The only square dish / pan I had was a glas dish but it was way too shallow, so I made a "collar" from baking paper to heighten the sides. Worked like a charm.
It was a great success and tasted great (thanks to the Woollies box cake which works out perfectly)
