"Heavenly Delight" -- a wonderful fudge recipe

Fudge always makes a nice kitchen gift all by itself, in combination with other homemade candies, or as an addition to a cookie tray. Here is our family's top favorite in the fudge department:

HEAVENLY DELIGHT
1 cup peanut butter chips
1 cup semisweet chocolate chips
2 1/2 cups sugar
7-ounce jar marshmallow fluff
3/4 cup evaporated milk
1/4 cup butter (1/2 stick)
1 tsp. vanilla

Line an 8-inch square pan with foil, extending the foil over the edges
of the pan. Measure the peanut butter chips into a small bowl, and
measure the chocolate chips into a second small bowl. Set aside.
In a heavy 3-quart saucepan, combine the sugar, fluff, evaporated milk,
and butter. Cook over medium heat, stirring constantly, until the
mixture boils. Boil and stir 5 minutes. Remove from the heat and stir
in the vanilla.

Immediately pour half of the hot mixture into the peanut butter chips.
Stir until the chips are completely melted and incorporated into the hot
mixture. Quickly pour the peanut butter mixture into the prepared pan.
Stir the remaining hot mixture into the chocolate chips until they melt
and are completely blended in. Quickly spread this mixture over the
peanut butter layer.

Cool the fudge completely before removing it from the pan. Lift the
fudge out of the pan by the foil, put it face down on a plastic cutting
board and peel off the foil. Cut the fudge into 1-inch pieces.

This terrific recipe is also from Cook & Tell, my favorite cooking newsletter. The actual name of the fudge is "Double-Decker Peanut Butter Fudge". But when Esther, my daughters'
college roommate and friend, tasted this, she promptly named it "Heavenly Delight". And so it has been, ever since.
