A “cheese” cake

This is a picture of my 10th birthday cake. The photograph is pretty bad, but the cake was beautiful, and very original. I don’t remember how I ended up requesting a cake in the shape of Swiss cheese (though I loved Gruyere as a kid), but I know I enjoyed it.
Both my kids have said they’d like a cake like this – I imagine it’d be too expensive to have it made and I’m not an artist.
