Using prebaked, cut-out hearts rebaked inside of cupcake batter.
Basically you split the batter, tint a portion red, bake it, then cut out heart shapes. Then take the rest of the white batter, put a bit in a the cupcake pan, stand one of the red hearts inside while adding more batter around to hold it in place, then bake those.
You see the heart when you cut open the cupcake.
Sweet idea.
