Birthday Cake Fudge

** Recipe from Mrs. Bettie Rocker **

* 3 c. sugar

* 1 1/2 sticks margarine
* 5 oz. can (2/3 c.) evaporated milk
* 12 oz. chopped white chocolate chips
* 7 oz.  jar marshmallow creme
* 3-4 Tbl. yellow cake mix (just the powdered MIX, not batter)
* 1 tsp. vanilla
* blue food coloring
* rainbow sprinkles

Line an 8 or 9" square pan with foil, leaving the ends hanging over the edges of the pan. Spray foil thoroughly with nonstick spray.  Place sugar, margarine, & evaporated milk in a heavy saucepan over med. heat. Bring to a full rolling boil, stirring constantly, and let boil 4 min. Remove from heat.  Add chocolate chips, marshmallow creme, & cake mix, stirring until chocolate chips are melted. Add vanilla & mix well.  Working quickly, pour about 1/3 of the fudge in a bowl and add a few drops of blue food coloring, mixing and adding until you achieve the desired shade. Pour white fudge into prepared pan, spreading evenly. Spoon blue fudge over the top, spacing it out. Using a sharp knife, draw swirls through the blue and white to create a marbled effect. Sprinkle the top generously with rainbow sprinkles before the top sets up.  Let store at room temperature until cool, then place in the refrigerator until firm.
