Place cupcake liners in 12 muffin cups. With kitchen shears, cut each biscuit into 4 pieces. In a small bowl, combine the maple syrup and melted butter. In a separate bowl, mix the sugar, cinnamon, and chopped pecans. Dip each biscuit piece into the maple butter, and roll in the sugar mixture. Place 3 or 4 coated pieces in each muffin cup, pressing to compact (see Note). Bake the muffins for 15 to 17 minutes. Allow to cool in the pan for 5 minutes before removing to wire racks. Serve warm.
