Looking for a different kind of Valentine for your kiddos? Check out these crayon hearts! All you need are some old crayons and a silicone cupcake mold. Break your crayons down and fill the mold just less than half way and put into the oven at 250 degrees for about 15-20 minutes. Its recommended that you place the mold on a cookie sheet before placing in the oven. Once the crayons are melted, pull the tray out of the oven and let cool completely before popping out of the mold! It's that easy!!
