In a medium saucepan over low heat, combine the Snickers bars, cream and semi-sweet chocolate chips (I like to use a double boiler just to make sure my sauce doesn’t burn or scorch).
Simmer the sauce slowly until the chocolate and candy bars are melted and the sauce is smooth.
In the meantime, preheat oven to 350 degrees.
Place butter in an 8 x 8 baking dish. Place butter in the oven and allow to melt, about 5-7 minutes.
In a separate bowl, blend remaining sugar, flour, baking powder, milk, and salt. Pour mixture over the melted butter. DO NOT STIR!
Pour Snickers sauce over the flour. Again, DO NOT STIR!
Bake for 1 hour or until crust has risen to the top and is golden brown.
