Three-Way Fudge

Directions

   Note: For each layer combine ingredients in a 2-cup pyrex measuring cup and microwave for 70 seconds on high. Remember that chocolate chips maintain their shape even after they're melted so don't go by appearance. You have to stir them to be sure.

   Melt the following together - 1 cup semisweet chocolate chips, scant half-cup sweetened condensed milk, 2 tablespoons butter.

   Stir to make sure everything's melted and then spread it out in the bottom of the 8-inch square pan you've prepared. Let it sit on the counter until it's cool and slightly hard to the touch.

   Melt together - 1 cup white chocolate chips, scant half-cup sweetened condensed milk, 2 tablespoons butter.
