start by melting the chocolate and vanilla candy melts separately. The amount of candy melts you use will depend on how big a batch of popcorn you are making and how chocolate-y you want it.
Pour the melted chocolate into the squeeze bottles.
Next, add some mini marshmallows. We really didn't measure these out unless you count 3 child sized handfuls as measuring.
After you add the marshmallows shake up the bowl so that they can become mixed with the popcorn. Then squeeze the melted vanilla and chocolate candy melts all over the popcorn. You will want to stop every once in a while to shake up the popcorn so that the chocolate gets evenly distributed.
Next, shake on some sprinkles and let the whole thing sit until the chocolate hardens. Ours took about 30 minutes.
Make sure your popcorn is free from loose kernels The chocolate can make them stick to the other pieces of popcorn. They are hard to spot and you don't want to bite down on them.
