Make delicate, buttery oatmeal lace cookies that spread thin and develop a beautiful caramelized flavor. This recipe yields cookies with satisfyingly crispy edges and a slightly chewy center.

Ingredients

Scale
  • 1/2 cup unsalted butter, softened
  • 1/2 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1 cup old-fashioned rolled oats
  • 1/2 cup finely chopped pecans or walnuts (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats. Do not use wax paper.
  2. In a medium bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
  3. Beat in the egg and vanilla extract until just combined.
  4. In a separate small bowl, whisk together the flour and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just incorporated.
  5. Stir in the rolled oats and any optional chopped nuts. The dough will be soft.
  6. Drop rounded teaspoons of dough onto the prepared baking sheets, spacing them at least 3 inches apart, as they will spread significantly.
  7. Bake for 6 to 8 minutes, watching closely. The edges should be deep golden brown and lacy. For crispier cookies, bake closer to 8 minutes. For a slightly chewier center, pull them out closer to 6 minutes.
  8. Remove the sheets from the oven. Let the cookies cool on the baking sheet for 2 minutes to set their shape.
  9. Carefully transfer the cookies to a wire rack to cool completely. They will crisp up as they cool.

Notes

  • For maximum crispiness, flatten the dough balls slightly with the bottom of a glass before baking.
  • If you prefer a chewier texture, reduce the baking time by 1 minute and allow them to cool on the pan for 3 minutes before moving them.
  • These cookies are excellent dipped halfway in melted dark chocolate once fully cooled.
  • This recipe works well for holiday oatmeal treats and afternoon tea cookies.
