Preheat oven to 375.

Cover a cookie sheet with parchment paper.

Mix together corn starch and powdered sugar in a shallow dish.

In a large bowl, mix together butter, cake mix, and eggs (this will be thick).

Add enough green food coloring to get bright green (a lot).

To keep your hands from getting all green, use 2 spoons to gather a chunk of dough and drop it into the sugar starch mixture.

Roll the spoons around to cover well. Then, pick up and roll into a ball and place on a cookie sheet.

Make sure you don't place them too close together, as they will spread a bit.

Bake for about 8-10 minutes, or until the edges are set and the centers are still slightly soft.

Remove the cookies from the oven, and while they are warm, press a red candy melt into the center of each cookie, then place a pink or red candy heart on top of the candy melt. Note: If the candy melts seem to firm, try popping them into the microwave for 5-10 seconds.

Allow the cookie sheet to cool for several minutes before transferring to the cooling rack.
