Ingredients

Dry Ingredients

  • 1½ cups all-purpose flour
  • 1 cup rolled oats
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ¼ teaspoon salt

Wet Ingredients

  • ½ cup unsalted butter (softened)
  • ¾ cup creamy peanut butter
  • ¾ cup brown sugar
  • ½ cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract

Optional Add-ins

  • ½ cup chocolate chips
  • ¼ cup chopped peanuts
  • ½ teaspoon cinnamon

Equipment Needed

  • Large mixing bowl
  • Medium bowl
  • Electric mixer or whisk
  • Baking tray
  • Parchment paper
  • Cookie scoop or spoon
  • Cooling rack

Instructions

Step 1: Prepare the Oven

Preheat your oven to 175°C (350°F).

Line a baking tray with parchment paper to prevent sticking and ensure even baking.

Step 2: Mix the Dry Ingredients

In a medium bowl, combine:

  • Flour
  • Rolled oats
  • Baking soda
  • Baking powder
  • Salt

Whisk everything together until evenly mixed.

Step 3: Cream the Butter and Sugars

In a large mixing bowl, beat together:

  • Softened butter
  • Peanut butter
  • Brown sugar
  • Granulated sugar

Mix for about 2–3 minutes until light, fluffy, and creamy.

Step 4: Add the Egg and Vanilla

Add:

  • Egg
  • Vanilla extract

Beat again until smooth and fully combined.

Step 5: Combine Wet and Dry Mixtures

Slowly add the dry ingredients into the wet mixture.

Mix gently until a soft cookie dough forms. Do not overmix.

If using chocolate chips or nuts, fold them into the dough at this stage.

Step 6: Shape the Cookies

Use a cookie scoop or spoon to form small balls of dough.

Place them on the prepared baking tray, leaving space between each cookie because they spread while baking.

You can gently flatten the tops slightly with your hand or a fork.

Step 7: Bake the Cookies

Bake in the preheated oven for 10–13 minutes or until the edges become golden brown.

The centers may still look soft, but they will continue to set as the cookies cool.

Step 8: Cool the Cookies

Remove the tray from the oven and let the cookies rest for 5 minutes.

Transfer them carefully to a cooling rack and allow them to cool completely.
