In a large bowl, mix the biscuit mix and milk together until you have a nice sticky dough.
In a separate smaller bowl, mix together the cinnamon and sugar, and set aside.
Spread a little flour or biscuit mix out on a clean surface, and knead your dough just enough so it's not sticky anymore.
Roll out the dough to about 1/4 inch thickness.
Brush the melted butter onto the dough; then sprinkle it with the cinnamon sugar mixture.
Roll the dough tightly into a log. Then cut it into 1-inch slices.
Place each slice upright in a foil pie plate.
Once the pie plate is full, cover it with plastic wrap; then place the whole pie plate down in a plastic gallon bag, seal it, and place it in your cooler.
