Get out and measure all of your ingredients.
Stir together white chocolate chips and condensed milk over low heat, until melted and smooth, for around 10 minutes.
Stir in cake mix or flour until blended, around 5 minutes.
Mixture must be smooth.
Remove from heat, and immediately divide into two bowls.
Add a couple of drops of gel color using toothpicks to each bowl and blend.

Take a fork and marble your fudge.
Sprinkle with candy eggs and sprinkles, then refrigerate overnight.
Cut into squares, serve, and enjoy!
