I made this cake for my neighbor's wife... it is a white cake that I added some edible confetti bits to (just to add some color in the inside). The outside was crumb coated with buttercream, the covered with MMF. I cut the heart shapes out after I put the MMF on the cake. Then I cut out the hearts shapes in different colors and put back into the cutouts.. smaller hearts were placed on top of the larger heart cutouts and really small hearts were placed randomly all over the cake
