Step 1

Make cupcakes according to recipe directions.

Step 2

Line a muffin tin with cupcake liners.

Step 3

Spoon batter into liners, being careful not to fill each cupcake more than 1/2 full of batter. (If you fill them too full, they will loose their heart shape!)

Step 4

After filling the liners, place a marble between the liner and the pan. You will see the cupcake take the shape of a heart!

Step 5

Bake cupcakes according to recipe directions. Allow to cool completely before frosting.
