Marble Fudge

This is my favorite treat to make and give this time of year.  I always send some to work with my husband.  It is THE most smooth and delicious fudge I have ever made.  The secret is the cream cheese!

Quickly stir in marshmallow creme and vanilla

In the large pot with remaining marshmallow mixture stir milk chocolate chips, semisweet chocolate chips and cocoa
Pour half of the white mixture into the bottom of the 9x13 pan, spreading evenly
Quickly pour half of the chocolate mixture over top, spreading evenly then repeat
Swirl a knife through mixtures for marbled design and smooth the top

Turn pan upside down on cutting board to remove fudge
Peel off foil and cut into desired size pieces

*I like to trim the sides to make the pieces square
