Stop it! Stop it right now! This is ridiculous. Stop screwing around with a good thing.
Peanut M&Ms are great. This barely tastes different on the front end and leaves a strange after-flavor that makes you wonder why you bothered to try something different.
Missed opportunity: give it a coffee flavor.
Better yet, replace the nut with an actual coffee bean. People love chocolate-covered coffee beans. Make it one step better and coat it in m&m shell goodness! Charge more. Morale more money.
Recommendation: don’t bother. Get the peanut butter ones.
