About This Recipe

Oatmeal Cookies needs the right balance of sweetness, structure, and cooling time.

Mix carefully and let it cool or set fully before serving.

Ingredients

  • 1 cup all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon baking powder
  • ½ teaspoon fine sea salt
  • ½ teaspoon ground cinnamon
  • ½ cup salted butter ((softened))
  • ½ cup granulated sugar
  • ½ cup light brown sugar ((packed))
  • 1 egg
  • 1 teaspoon pure vanilla extract
  • 1 ½ cup old-fashioned oatmeal
  • 1 cup mix-ins ((chocolate chips, raisins, cinnamon chips, etc.))

Ingredient Notes

  • Flour or structure: Measure carefully so the dessert sets with the right texture.
  • Sugar: Sugar affects both sweetness and browning.
  • Fat: Butter, oil, or cream adds richness and tenderness.
  • Cooling time: Let the dessert cool before slicing or storing.

Instructions

  1. 1

    Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius). Line two large baking sheets with silicone baking mats or parchment paper. Set aside.

  2. 2

    Combine the flour, baking soda, baking powder, salt and cinnamon in a small bowl. Set aside.

  3. 3

    Put softened butter, granulated sugar and brown sugar in the bowl of a standing mixer and beat on medium-high speed for 1 minute, or until light and fluffy.

  4. 4

    Add egg and vanilla and beat on medium-high speed for 1 minute.

  5. 5

    Add the dry ingredient mixture and beat on medium speed until combined.

  6. 6

    Then, beat in the oatmeal on low speed.

  7. 7

    If desired, beat in mix ins until evenly distributed in the dough.

  8. 8

    Use a 1 ½ to 2 Tablespoon cookie scoop to measure out portions of dough.

  9. 9

    Roll the dough into balls and place evenly spaced on the prepared cookie sheet - about 1 ½ inches apart.

  10. 10

    Gently press down the tops of the oatmeal cookies until they are slightly flattened.

Katy’s Kitchen Note: Cool fully before slicing so the texture has time to set.

Storage and Reheating

Store covered in the refrigerator if the dessert is creamy or contains dairy.

Keep tightly wrapped so it does not dry out or absorb odors.

Common Mistakes to Avoid

  • Wrong pan size: A different pan changes thickness and timing.
  • Slicing hot: Many desserts need cooling time to set.
  • Loose storage: Uncovered desserts dry out quickly.
