Melt your chocolate chips. You can either use the microwave to do this or the stove top. If you do it over a burner make sure it is set to low and you are stirring constantly. If you do it in the microwave go in 30 second increments so you don't burn the chocolate.
Mix your condensed milk, melted chocolate and melted butter.
Add in as much of your food coloring as you want to make it as pink as you want. I added about 10 drops. Mix thoroughly so the color isn't streaky.
Pour the mixture into a baking dish that's lined with wax paper or parchment paper.
Even out the top and add your sprinkles! As a tip, add any chunky sprinkles first. If you add the crystallized color sugar sprinkles first the others won't stick as well.
Refrigerate for at least one hour then cut and enjoy!
