Maple Vanilla Swirl Fudge

Line a 10 x 7-inch baking pan with foil.

Coat the foil lightly with nonstick vegetable oil cooking spray.

Melt the chocolate pieces in the top of a double boiler over hot, not boiling, water.

Stir the chocolate constantly until melted.

Add the half and half; stir the mixture until it is smooth and glossy. The mixture may look separated at first, but will become smooth and glossy as you stir.

Stir together 1 generous cup of melted chocolate with maple extract and nuts.

Alternately spoon white chocolate and maple mixtures in prepared pan; swirl together with knife.

Refrigerate until set, 2 to 4 hours.

Cut into 24 squares. Refrigerate up to 1 month.
