Preheat
oven to 350 degrees.
Stir together flour, baking powder, baking soda, and cinnamon. Set aside.
In a large bowl, cream together the butter and 1 cup of white sugar until
light and fluffy. Beat in the egg and maple syrup. Gradually blend in dry
ingredients until just mixed. In a small dish, mix together the remaining
white sugar and the maple (or brown) sugar. Roll dough into 1-inch balls and
roll the balls in the sugar mixture. Place cookies 2 inches apart on
ungreased cookie sheets. Bake 8-10 minutes; cookies will be crackly on top
and look wet in the middle. Remove from oven and cool on wire racks.
