Thick and chewy peanut butter oatmeal chocolate chip cookies with creamy peanut butter, old-fashioned oats, all brown sugar, and semisweet chocolate chips.
Preheat your oven to 350°F. Line your baking sheets with parchment paper and set aside.
In a large bowl, cream together the softened butter, creamy peanut butter, and brown sugar until smooth and creamy.
Next, beat in the large eggs and vanilla extract just until combined.
In a separate bowl, mix together the dry ingredients: all-purpose flour, old-fashioned oats, baking soda, baking powder, and salt.
Gradually mix the oat and flour mixture into the peanut butter mixture until a dough is formed.
Fold in your chocolate chips with a spatula or wooden spoon to evenly distribute them through the cookie dough.
Using a #40 cookie scoop (1.5 tablespoon cookie scoop) or tablespoon, drop the cookie dough balls onto your prepared baking sheets.
Bake the cookies in the preheated oven for 9-12 minutes, or until the edges are golden brown.
Remove your peanut butter oatmeal chocolate chip cookies from the oven and allow them to cool on the cookie sheet for 5 minutes before transferring them to a wire rack to cool completely.
Notes
All brown sugar, no granulated. This keeps the cookies soft and chewy.
Use creamy peanut butter. The oats add enough texture.
Cool baking sheets between batches. Warm sheets flatten the cookies.
