On a quick trip around IKEA with my partner, I insisted on stopping for some of the delicious almond chocolate cake. It was heaven, let me tell you! I think you can buy these in the supermarket now, so if there's not an IKEA near you, maybe you'll see it there.
My partner had a Prinsess cake which is a cream cake that has marzipan on the outside. I tried some and it was really nice as well, not too dense or overpoweringly sweet. It also looks like a little piece of art on the (paper) plate!
