In a stand mixer, beat together the butter, the brown sugar, and the granulated sugar for about 30 seconds. Add baking powder, baking soda, and cinnamon. Beat until combined.

Add eggs and vanilla, beating until combined and scraping down the sides.

Beat in as much flour as you can with the mixer, using a wooden spoon to mix in the rest.

Stir in the oats, rolos, chocolate chips, and pecans.

Drop by rounded tablespoons onto a parchment lined baking sheet. Bake at 375° for 8-10 minutes, until edges are golden. Let cool on baking sheet for a few minutes before transferring to wire rack.
