Preheat oven to 400 degrees
Combine mix and milk and beat until smooth. If dough feels too sticky, add more mix-up to 1/4 c.
Turn dough out onto a surface dusted with baking mix or plain flour, roll dough into a ball to coat, and knead gently 20 times. Roll dough out to 1/2" thickness and cut int 2" circles or squares. Mixture will be a bit looser than the dough for regular biscuits. Drop by spoonfuls onto an ungreased cookie sheet and bake for 8 to 10 minutes.
Just before baking brush tops with melted butter and dust with cinnamon sugar.
