Let your cut pieces sit out on a lined baking tray, uncovered, for about a day so they set up. When they're dry to the touch, toss them in a sealed box in your fridge. They'll be good for weeks, or you can stash them in the freezer for a couple of months.

Grab a piece of colored dough, about the size of a big marble (30 grams). Roll it into a rope using your hands on a cutting board. Use a sharp knife or pizza cutter to chop it into tiny bites.

Break the dough up into three or four chunks. Drop a few dabs of food coloring onto each and use your hands to mix until the color is how you want it. Swirly or one solid color—whatever you feel like.

Dump in your powdered sugar, condensed milk, vanilla, and peppermint (or whatever flavor) into the butter. Mix it up until you’ve got a soft dough. If it’s sticking all over, knead in up to 30 grams powdered sugar until it firms up.

In a big bowl, whip up the soft butter with your electric mixer. Give it about half a minute, just until it turns nice and creamy.
