FAQ:

It’s a personal preference. I prefer quick oats for a softer texture. Using old-fashioned oats will give the cookies a heartier texture with more crunch and chew.

It depends on the recipe. I wouldn’t consider this recipe healthy because there is a good amount of butter and sugar in it (that’s why it tastes so good) but it’s healthier than your average chocolate chip cookie.

Yes, oatmeal cookies freeze well and can be frozen for up to 3 months if properly stored in an airtight freezer-friendly container or ziplock bag.

No, the oatmeal texture will not be apparent. It’s best to use quick or old-fashioned oats.

Old-Fashioned Oatmeal Cookies


  • Author: Lily Ernst
  • Total Time: 25 minutes
  • Yield: 2 dozen

Description

These simple oatmeal cookies are soft and chewy with crispy outer edges. They have warm notes of brown sugar and a hint of cinnamon spice.


Ingredients

  • 3/4 cup (170g) unsalted butter, softened
  • 1 cup (200g) packed brown sugar
  • 1/2 cup (100g) granulated sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • 1 ½ cups (190g) all-purpose flour
  • 1 tsp baking soda
  • 1 tsp ground cinnamon
  • 1/2 tsp salt
  • 3 cups (270g) quick rolled oats

Instructions

  1. Preheat oven to 350F. Line 2-3 baking sheets with parchment paper or silicone baking mats.
  2. Using an electric mixer or stand mixer with paddle attachment, beat the butter, brown sugar and granulated sugar until fluffy, about 2-3 minutes. Add in the eggs and vanilla, beat again until thoroughly mixed.
  3. In a separate bowl, toss together the flour, baking soda, cinnamon and salt. Add to the wet ingredients and mix until just combined. Gently stir in the oats by hand with a wooden spoon until just combined.
  4. Roll the dough into rounded golfball-sized balls (about 2 tablespoons each) and place about 2 1/2″ apart, so you’ll only get about 8 or 9 cookies on each baking sheet. Flatten slightly with your hands.
  5. Bake for 9-11 minutes or until the edges just start to turn golden brown and center still looks moist. Let cool on baking sheet for 5 minutes before transferring to wire rack to cool completely.
