I can't take any credit for the design of this cake as I saw the idea on Wilton's website last year. I wasn't sure how difficult it would be, but it was really fun. It is a yellow cake with buttercream icing and white fondant. Then I cut out the hearts from six colours of fondant and applied them to the white fondant. I would line up the cookie cutter and cut out a part of the heart before adding the next one...then repeat. My daughter used a food writer marker to add the writing.
