Conversation Heart Fudge

** Recipe from Family Fun **

Dark Chocolate Layer:
* 1 1/4 c. semisweet chocolate chips
* 1/2 c. sweetened condensed milk
* dash of salt
White Chocolate Layer:
* 1 1/4 c. white chocolate chips
* 1/2 c. sweetened condensed milk
Other ingredients/materials
*  aluminum foil
* 64 conversation hearts

Line an 8" square pan with foil. Set aside.  In a med-size, micro-safe bowl, combine dark chocolate layer ingredients. Microwave mixture on high at 30-sec. intervals until chocolate is melted (about 1 min.), stirring at each interval. When mixture's smooth, use a spatula to spread it evenly into pan.  In another med-size micro-safe bowl, combine white chocolate layer ingredients. Repeat melting process as described in step 2, but stir at 20-sec. intervals, as white chocolate tends to scorch easily. Spread white chocolate evenly over dark chocolate layer.  While fudge is still warm, use a knife to gently score it into 1" squares, then put a candy heart on top of each square.  Chill fudge uncovered in fridge for at least 2 hrs, or until firm. Lift foil to remove fudge from pan & place whole hunk of fudge on a cutting board. Use a large knife to cut apart squares, then peel off foil from bottom.
