Place a marble in the center of the "top" of the cupcake
Fold a small piece of foil to fit on both sides of the cupcake liner
Use a ¼ measuring cup to add the batter to the cupcake tin.
Bake for 15-18 mins
Remove and let cool in the pan for 20-25 mins
Once removed you should have a heart-shaped cupcake!
Frost as you would like
