I saw something like this on the internet and realized that this was the answer to Girl Scout Thin Mint cookies for gluten-free eaters. Here’s how I made my first batch. It’s not very sweet; if you want to make it sweeter, you can coat the pieces with powdered sugar or a mixture of cocoa and powdered sugar.
9 C rice Chex
1 C semi-sweet chocolate chips
1/3 stick butter
1 t peppermint extract
1/4 t salt
1 C unsweetened cocoa powder
Put the chex in a very large bowl. In a double-boiler or microwave, melt the chocolate chips and butter together, being careful not to overheat. Stir in the peppermint extract. Pour over the cereal and mix gently, coating the pieces. Allow to cool, then put it into a very large plastic bag. Sprinkle the cocoa powder and salt over the cereal in the bag, close it up, and shake to coat.
