Macadamia Nut Fudge

1 (7 ounce) jar macadamia nuts, coarsely chopped
1 (7 1/2 ounce) jar Marshmallow Cr?me
1 cup granulated sugar
1/2 cup heavy or whipping cream
4 tablespoons butter
1 (12 ounce) package semisweet chocolate chips
1 teaspoon vanilla extract

Lightly butter an 8-inch square baking pan.

In heavy 3-quart saucepan over medium heat, heat Marshmallow Cr?me, sugar, heavy or whipping cream and butter to boiling, stirring occasionally. Boil 5 minutes, stirring constantly.

Remove saucepan from heat; stir in chocolate chips and vanilla extract until chocolate melts.

Set aside 1/2 cup macadamia nuts; stir remaining nuts into chocolate mixture. Pour fudge into pan. Sprinkle reserved macadamia nuts over fudge, pressing firmly into fudge. Cover pan and refrigerate fudge until firm, about 2 hours.
