Cream together butter and sugar. Add eggs and vanilla.
Mix dry ingredients and add to butter mixture. Roll to desired thickness.
Cut out shapes making a hole for the stained glass effect.
Unwrap a Jolly Rancher and place in the center of your cookie - Bake for about 8 minutes on a cookie sheet lined with parchment paper.
Let cool on the pan. This step is important because the candy needs to cool and harden up. And there you have it - Stained Glass Valentine Cookies! We ran out of Jolly Ranchers before we ran out of dough so we made frosted sugar cookies as well.
