Heat oven to 400°F. Separate dough into 10 biscuits; separate each into 2 layers. On ungreased large cookie sheet, arrange biscuit rounds 2 inches apart.
Bake 7 to 11 minutes or until golden brown. Remove biscuit rounds from cookie sheet; place on cooling rack. Cool completely, about 10 minutes.
Top each baked biscuit round with about 1 teaspoon pizza sauce; top each with 2 or 3 slices pepperoni.
With aerosol can of cheese, squeeze cheese faces on top of snacks. Serve immediately, or store in tightly covered container in refrigerator up to 1 hour.
