Step 1

Line a baking sheet with parchment or wax paper. Draw a 13 x 9-inch rectangle and then flip the parchment over.

Step 2

Microwave half of the morsels in a medium, uncovered, microwave-safe bowl for 1 minute; stir. Add two drops of pastel food coloring and mix until combined (adjust coloring to your liking, adding more if needed). Microwave second half of morsels in a medium, uncovered, microwave-safe bowl for 1 minute; stir until very smooth.

Step 3

Add a few tablespoons of the melted white morsels to the edge of the rectangle on the parchment. Spread the melted white morsels into a vertical line that is an inch wide. Next, spread a few tablespoons of the pastel-colored melted white morsels in a vertical line that is an inch wide. Repeat, alternating between the two. Using a butter knife, draw diagonal lines through the melted white morsels stripes. Repeat in the opposite direction. Transfer to the refrigerator to set for 20 minutes.

Step 4

Break into small pieces.
