Crush 3 cups of pretzels and mix with butter and brown sugar. Spread pretzel mixture into the bottom of a 9x13 pan and bake at 350 degrees for 12 minutes
While crust is baking, combine all cheesecake ingredients and mix with blender until creamy. Once crust is done, pour gently over the top of the crust and bake in oven for 30-35 minutes or until a toothpick comes out clean.
Once the cheesecake has baked, mix condensed milk and chocolate together in a saucepan on low heat until creamy and then pour over top of the cheesecake. Add M&M's and put into fridge to cool completely before serving.
Cut into small bars and serve with milk! Enjoy!
