Melt butter in a medium saucepan over medium heat. Once butter has melted add milk and semi sweet chocolate chips stirring constantly.

When the chips melt add the condensed milk and stir. Add vanilla and whipping cream and stir. Remove from heat and let cool. Well mixture is cooling, line a casserole pan with parchment paper. Once the sauce pan is cool enough to touch, pour the mixture into the prepared pan. Smooth out the top of the mixture with a spatula. Cover pan with saran wrap and put in the fridge. let cool and set for at least 5 hours. Enjoy!!!
