Equipment
Method
- Heat the oven to 350°F and line two rimmed baking sheets with parchment paper.
- In a large bowl, beat the butter, brown sugar, and granulated sugar until creamy, about 2 minutes.
- Beat in the egg and vanilla until combined.
- In a medium bowl, whisk together the flour, oats, cinnamon, baking soda, and salt.
- Mix the dry ingredients into the butter mixture just until combined, then fold in the apple.
- Chill the dough for 30 minutes.
- Scoop the dough into 1 1/2-tablespoon portions onto the prepared sheets, spacing them about 2 inches apart.
- Bake at 350°F for 13 to 16 minutes, swapping the sheets between racks and rotating them front to back halfway through, until the edges are golden and the tops look set.
- Cool the cookies on the sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool completely.
Notes
Chill the dough for the full 30 minutes so the cookies hold their shape, and cut the apple into even 1/4-inch dice. Store airtight at room temperature for up to 3 days or freeze for up to 2 months. For a gluten-free version, use a gluten-free 1:1 flour blend and certified gluten-free oats.
