Make It
Step 1
Line 8-inch-square baking pan with foil.
Step 2
Combine morsels and sweetened condensed milk in large, microwave-safe dish. Microwave on HIGH (100%) power for 1 minute; stir until smooth.
Step 3
Spread into prepared baking pan. Place preserves in a small, microwave-safe dish. Microwave at 10 second intervals until slightly warm and easy to stir. Pour evenly over fudge. Use a knife to create a marble effect, being careful to not cut foil. Refrigerate for 4 hours or overnight. Lift from pan. Cut into 36 pieces. Store in refrigerator.
