Ingredients

Scale

Wet Ingredients

  • 1/2 cup unsalted butter (112 grams), softened
  • 1/2 cup packed brown sugar (100 grams)
  • 1/3 cup granulated sugar (66 grams)
  • 1/2 cup peanut butter (120 grams)
  • 1 large egg
  • 1 tsp vanilla extract

Dry Ingredients

  • 3/4 cup all-purpose flour (94 grams)
  • 3/4 tsp baking soda
  • 1/4 tsp salt
  • 3/4 cup quick oats
  • 1/2 cup old-fashioned oats

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (180°C or 170°C fan forced). Prepare baking sheets by lining them with parchment paper or silicone baking mats for easy non-stick baking.
  2. Cream Butter, Sugars, and Peanut Butter: In a large mixing bowl, beat together the softened butter, brown sugar, granulated sugar, and peanut butter until the mixture is creamy and free of lumps, ensuring a smooth base for the cookies.
  3. Add Egg and Vanilla: Mix in the egg and vanilla extract thoroughly to incorporate moisture and flavor into the dough.
  4. Combine Dry Ingredients: Add the all-purpose flour, baking soda, and salt to the wet mixture. Start by stirring a few times by hand, then use a mixer on low speed to fully combine the ingredients until just mixed.
  5. Incorporate Oats: Turn off the mixer and gently fold in both the quick oats and old-fashioned oats by hand, evenly distributing them in the dough without overmixing.
  6. Form Dough Balls: Scoop the dough into balls about 1 to 1.5 tablespoons each, roughly the size of a ping pong ball. Place the dough balls about 2 inches apart on the prepared cookie sheets, leaving them unflattened as they will spread during baking.
  7. Bake Cookies: Bake one cookie sheet at a time in the center of the preheated oven for 9 to 12 minutes, or until the cookie tops are just set. Avoid overbaking to keep them soft and chewy inside.
  8. Cool Cookies: Remove the cookies from the oven and let them cool on the baking sheet for 5 to 10 minutes. Then transfer them to a wire rack to cool completely, ensuring they firm up and hold their shape.

Notes

  • Do not flatten the cookie dough balls before baking; this keeps the texture chewy.
  • Baking one sheet at a time ensures even cooking and better texture.
  • For extra crunch, consider folding in chopped peanuts or chocolate chips.
  • Store cookies in an airtight container at room temperature for up to one week.
  • To keep cookies soft longer, place a slice of bread in the container to maintain moisture.
