Get your 8x8 square baking pan ready by lining it with parchment paper, then give it a light spray with cooking spray. Set up individual bowls for each color you plan to use.
02 -
Combine white chocolate chips and sweetened condensed milk in a large microwave-safe bowl. Heat for 1 minute, then stir. Keep microwaving in 30-second bursts, stirring between each one, until everything melts together into a smooth, thick mixture. Don't let it overcook or it'll seize up on you!
03 -
Divide your melted fudge base evenly between your prepared bowls - just eyeball the portions. Add 3-4 drops of food coloring to each bowl and mix until you get the shade you want. Split the powdered sugar between all the bowls and stir it in thoroughly.
04 -
Drop spoonfuls of each colored fudge randomly into your prepared pan, layering and overlapping the colors. Use the back of a spoon to gently smooth the top into an even surface.
05 -
Cover with plastic wrap and let it chill in the refrigerator for at least 4 hours, or better yet, overnight until it's completely firm.
06 -
Use the parchment paper to lift the fudge out of the pan, then slice it into 16 neat squares in a 4x4 pattern.
07 -
Color your frosting in whatever shades you like and put each color in its own piping bag. Pipe fun shapes, swirls, or lines on top of each square, then press googly eyes randomly on each piece to create adorable monster faces.
