Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
In a bowl, combine oil, sugar, and maple syrup. Stir in egg.
Add all dry ingredients. Finally, stir in pecans.
Scoop cookie dough onto prepared baking sheets. Bake for 7-8 minutes, until center is just set. Cookies will firm up slightly as they cool, but they will retain a soft, chewy texture. Let cool.
Meanwhile, in a small bowl, combine all glaze ingredients. Add to a piping bag, snip off the tip, and drizzle over cooled cookies. Let set.
