In a 2 quart pot, combine milk and sugar. Cook over medium heat until mixture comes to a boil, and then simmer for 5 minutes. Remove from the heat and quickly add marshmallows, peanut butter and M&M’s®. Mix well.
Pour into a prepared pan and allow cool, then cutting and wrapping tightly.
I love making fudge for backpacking trips. It is great for group trips. It is sweet, high in fat, easy to carry and almost everybody loves fudge.
All our fudge recipes are molded into an 8×8″ pan that is lined with parchment paper (butter the pan first and the paper will stay in place when pouring). Refrigerate after pouring, then pop out, take off paper. Trim the fudge (eat them scraps of course!), wrap in 2 layers of plastic wrap, then put it in a gallon storage bag for carrying. Most fudge will do fine up into the mid to high 60’s for temps. Fudge made at home should be eaten within a week or less. It does not have preservatives in it, as commercial items would.
