This might not be a food related post, but it was a fun crafty idea using a silicone heart pan I had on hand. (I found mine a couple of years ago at Target, for just a few bucks.) Anyway, I wanted Judah to make his Valentines this year for his cousins and grandparents, and this was the perfect option for him that didn't require any skills, and only the ability to drop crayon pieces into the cavities.
Instead of throwing away any broken crayons, unwrap them and save them in a ziplock bag for an activity like this. You can use any silicone mold. Once you have quite the collection of crayons (I needed about 6 ounces to fill the pan I had) chop them up into small pieces (recommend plastic cutting board), drop them into the molds and bake in the oven at 230 degrees F for 15 minutes.
