Easy Microwave Fudge

1 (14 oz) can sweetened condensed milk
1 (12 oz bag) semi sweet chocolate chips
1 cup milk chocolate chips
1/4 cup butter, cut in pieces
1/2 cup chopped pecans
1 tsp vanilla

• Line a 9×9 inch pan with foil, going in both directions and letting some hang over the edge for easy removal later.  Spray with cooking spray.
• In a large microwave safe bowl put the chocolate, the butter and the condensed milk.
• Microwave on high 1 1/2 minutes.  Remove and stir.
• If the chocolate is not completely melted, put in back in the microwave for another 15 seconds and stir again, letting the residual heat in the bowl finish melting the chocolate.
• When it’s completely smooth, add in the vanilla and nuts and stir to combine.
• Spread into the prepared pan and smooth out the top.
• Refrigerate for 2 hours.
• Remove the foil sling from the pan and carefully peel it off the fudge.  Cut into squares with a sharp knife.
