Once it is open, transfer the all-purpose baking mix to an airtight container, and store in a cool, dry place such as the pantry.
Whisk together first 3 ingredients until smooth. Stir in baking mix until well blended. Divide dough into 12 equal portions, and arrange on a lightly greased baking sheet. Brush tops of dough with melted butter.
Bake at 450° for 7 to 8 minutes or until lightly golden. Let stand 5 minutes before serving. Garnish, if desired.
Note: For testing purposes, we used Bisquick All-Purpose Baking Mix.
