1 cup butter
1/2 cup granulated sugar
1 cup firmly packed brown sugar
1 cup peanut butter
2 large eggs
2 Tbsp vanilla
2 cups quick-cooking rolled oats
2 1/2 cups flour
1 tsp baking soda
12 oz chocolate chips

Preheat oven to 350 degrees. In a medium bowl with a mixer on medium speed, cream butter and sugars until smooth. Add peanut butter and mix until combined; then add eggs and vanilla, scraping down sides of bowl as needed.

In another bowl, whisk together oats, flour and baking soda. Add to butter mixture and mix on low until well blended. Stir in chocolate chips.

Drop dough by rounded tablespoons 1inch apart onto ungreased baking sheets. Bake 10-12 minutes or until lightly browned but still soft in the center. Note: I flattened the dough balls slightly before baking.
