how to make striped rainbow fudge

Here, we use our classic fudge recipe and do the math to divide the combination into six different colors. To make this fudge you will need two 14-ounce cans of sweetened condensed milk and 6 cups of white chocolate chips (or, three 12-ounce bags). For food coloring, I prefer Americolor Soft Gel Pastes. See below for the specific colors!

Line an 8-inch square baking pan with non-stick foil or parchment paper lightly greased with cooking spray.

Divide two 14-ounce cans of sweetened condensed milk into six microwave-safe bowls. Each bowl should have about 1/3 cup plus 1 tablespoon.

Pour 1 cup of white chocolate chips (remember, we have 6 cups total) into one of the bowls with the sweetened condensed milk. Microwave at 70 percent power for 90 seconds. Stir very well, using the residual heat to fully melt the chocolate chips until they are smooth. Add purple food coloring. Spread evenly in the bottom of the prepared baking pan. Place in the freezer.

While the purple layer is in the freezer, repeat the above instructions with blue food coloring. The purple layer should be in the freezer about 10 minutes total. After 10 minutes, spread the blue layer over the purple layer. Return to the freezer.

Repeat with a green food coloring layer, yellow, orange, and red, letting each layer remain in the freezer about 10 minutes.

Return to the refrigerator to fully set the fudge, about 2 hours. Cut into 25 squares.
