how to make Peanut Butter Oatmeal Cookies

Ingredients

1 cup quick oats (or rolled oats)
3/4 cup all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup unsalted butter (softened to room temperature)
1/2 cup creamy peanut butter (natural or processed)
1/2 cup brown sugar (packed)
1/4 cup granulated sugar
1 large egg (at room temperature)
1 teaspoon vanilla extract
1/2 cup chocolate chips (optional)
1/4 cup chopped nuts or raisins (optional)

Directions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar until the mixture is light and fluffy.
Add the egg and vanilla extract to the creamed mixture, then mix until fully combined.
In a separate bowl, whisk together the flour, oats, baking soda, and salt.
Gradually mix the dry ingredients into the wet mixture until a soft dough forms. If you want, fold in the chocolate chips or other add-ins.
Use a cookie scoop or tablespoon to form dough balls and place them 2 inches apart on the prepared baking sheet. Gently press them down slightly.
Optional: Chill the dough for 20–30 minutes before baking. This helps prevent spreading and enhances chewiness.
Bake the cookies for 9–11 minutes, until the edges are set but the centers still look slightly soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
