Heat the olive oil in a large skillet over medium-high heat. Add oats then cook and stir until starting to brown and crisp, about 5 minutes. Remove from heat and spread out on a cookie sheet to cool.

Melt the butter in the same pan over medium heat. Stir in the honey and brown sugar; cook, stirring constantly, until bubbly. Return the oats to the pan. Cook and stir for another 5 minutes or so. Pour out onto the cookie sheet and spread to cool.
