Andes mint fudge.
This was a simple experiment that turned out quite well. Use your favorite fudge recipe and use Andes mint baking chips in place of the chocolate. For example, my recipe calls for 12 oz of chocolate. The Andes mint baking chips came in a 10 oz bag, so I did those 10 oz plus 2 oz semisweet Nestle chips. Varying the amount of Andes mint chips to chocolate chips or chocolate bits will change the strength of the mint in the fudge. Being a mint lover, the strength from the 10 oz/2 oz mix was very enjoyable.
