01 -
Heat your oven to 350°F and prepare three baking sheets with parchment paper or silicone mats.
02 -
Beat together the butter, peanut butter, brown sugar, and granulated sugar until the mixture becomes fluffy and well-combined (about 30 seconds to 1 minute).
03 -
Mix in the eggs and vanilla until everything is completely incorporated.
04 -
Add the flour, oats, baking soda, and salt. Gently mix until just combined to form a sticky dough.
05 -
Form golf-ball-sized portions of dough and place them on the baking sheets, with 8 cookies per sheet, spaced well apart as these cookies spread considerably.
06 -
Bake for 12 to 15 minutes until the edges brown and the tops look mostly set. For crispier cookies, bake until the tops look completely set.
07 -
Let the cookies cool directly on the baking sheet before enjoying.
