Preheat oven to 350° F. Oil an 8x8-inch pan with almond oil, and set aside.
In a food processor, grind the pecans to the consistency of meal. Transfer to a medium bowl and add the almond oil, maple syrup, eggs, cocoa, and arrowroot power. Stir to blend. Pour into the oiled baking pan.
Bake for 20 minutes or until a toothpick inserted in the center comes out clean. Let cool, then cut into 12 bars.
