Preheat oven to 350 degrees. Line 8x8 pan with parchment paper.
In a medium bowl, mix almond butter, maple syrup, brown sugar, egg, and vanilla extract.
In a small bowl, combine flour, oats, baking soda, and salt. Add this to the almond butter bowl. Mix well
Save 1/2 cup of dough for the topping. Press the remaining dough into the prepared 8x8 pan. Press evenly - it will be thin.
Top with chocolate chips.
Crumble remaining dough over the top. Press down slightly.
Bake for 16 - 18 minutes, or until slightly brown around the edges.
