Separate the prepackaged dough into 8 (or 10, depending on package) biscuits.

Mix the sugar and cinnamon together.

Using a 1-inch circle cutter, cut out the center of each biscuit.

Coat each biscuit and each center in the melted butter, then coat in the cinnamon-sugar mix.

Cook both biscuits and centers in oven according to package directions (i.e. 350°F for 12 minutes).
