After you have made the mac and cheese recipe, spread onto a cookie sheet to help with the cooling process. Place in fridge for approximately 30 minutes for best results.
Add remaining ingredients into a medium sized bowl and mix well with your hand.
You're going to need to pat 2 thin sized burger patties to equal one stuffed mac and cheese patty. So be sure to try to pat them a little thin, but at least a 1/4"
You're going to use approximately a 1/4 cup of mac and cheese in between the two hamburger patties. Be sure to seal the edges very well together, or they will burst open during the cooking process.
Cook the burgers to the temperature of your liking on the grill or in a pan, and then top off with cheddar jack cheese when you place it on the bun.
