Preheat the oven to 350 degrees. Line baking sheets with parchment.
Heat the butter in a saucepan while stirring continuously to prevent splattering until the butter solids begin to foam and brown. Once browned to a caramel or maple syrup color, remove from heat and let cool at room temp or in the fridge.
In a medium bowl, combine the oats, flours, baking soda, cinnamon and salt.
Once the browned butter has cooled at least to room temp (it is fine if it chills completely to fridge temp), combine it with the brown sugar in a large bowl using a hand mixer on a medium-high speed.
Add in the egg and yolk, then the vanilla. Blend with the mixer until fully combined.
With a large spatula, stir the oat mixture in by hand, then stir in any raisins, nuts or chocolate chips.
Using a small cookie scoop or tablespoon, place generous tablespoon-sized mounds of dough on the lined baking sheets approximately 2 inches apart. The cookies will spread quite a bit while cooking. You don’t need to flatten out the mounds of dough. You can roll them to keep the shape more uniform if you’d like.
Bake for 10 minutes, then remove and let cool completely before removing from the baking sheet. They will crumble very easily if you remove them before they have cooled.
