How to Make Grandma's Old Fashioned Oatmeal Cookies

  1. Preheat oven to 350°F (175°C). Line three baking sheets with parchment paper.
  2. In a medium bowl, whisk together 2 1/2 cups all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.
  3. In a large bowl, cream together 1 cup (2 sticks) unsalted butter and 1 1/2 cups granulated sugar with an electric mixer on low speed until the sugar is evenly distributed.
  4. Increase mixer speed to medium and beat for 1 minute, scraping down the sides of the bowl as needed. Add 1 large egg and beat for another 30 seconds.
  5. Gradually add the dry ingredients to the wet ingredients, one-third at a time, mixing on medium speed until just combined. Do not overmix.
  6. Stir in 3 cups rolled oats using a rubber spatula until evenly distributed.
  7. Using a cookie scoop or spoon, portion the dough into 24 equal-sized balls. Place 8 cookies on each prepared baking sheet, leaving some space between each cookie.
  8. Bake for 13-16 minutes, one baking sheet at a time, rotating halfway through for even baking. Cookies are done when the edges are golden brown.
  9. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
