In a medium (or large) sized pan melt your chocolate chips and butter. Add your can of evaporated milk. Heat on high. Stir constant.
Once it starts boiling, turn the heat down and add your toffee bits. Still stirring constantly.
Take off of heat and prepare your pan. I put a sheet of wax paper in an 8x8 baking dish then put a little bit of powdered sugar on top of the wax paper. Pour your fudge into the baking dish. Chill in fridge until firm.
