My thoughtful mother-in-law picked up this heart shaped silicone mold for me last year on clearance after Valentine's Day and I've been waiting nearly 365 to use it. I tried making these crayons last year and failed misearbly. I had read on a blog that you could use the much cheaper plastic candy molds to bake them. Well- not the molds I bought. My oven ate them alive. This year I went with the real deal.
Tips and Notes:
Crayons: I started with the mis-matched, broken and abused crayons from our stash. The first batch of co-mingled crayons worked ok. The second batch was all Crayola and it was far superior. The paper peels easier, they melt easier and cool more evenly.
Soak your crayons in ice water for 10-15 minutes and then peel. The paper comes off much easier and you don't end up with crayon under your nails.
We baked our crayons at 275 degrees for 10-15 minutes.
Once out of the oven we put the tray outside for 15 minutes. They cool pretty fast in Wisconsin
Bennet loved filling our her Valentine's. She made little hearts and smiley faces on them.
