Ingredients for Lemon Oatmeal Cookies

Gather these items:

1 cup (2 sticks) unsalted butter, softened
3/4 cup light brown sugar, packed
1/4 cup granulated sugar
2 large eggs
2 tablespoons lemon juice (freshly squeezed)
Zest of 2 lemons
1 teaspoon vanilla extract
1 3/4 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
2 1/2 cups old-fashioned oats
1 cup white chocolate chips (optional but highly recommended)
1 1/4 cups powdered sugar (for glaze)
2–3 tablespoons lemon juice (for glaze)
1 teaspoon lemon zest (for glaze)

How to Make Lemon Oatmeal Cookies Step-by-Step

Step 1: Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone baking mats. Set aside.
Step 2: In a large mixing bowl or stand mixer, cream the softened butter, light brown sugar, and granulated sugar together until light and fluffy, about 2 to 3 minutes.
Step 3: Beat in the eggs one at a time, then mix in the lemon juice, lemon zest, and vanilla extract. The batter may look slightly curdled due to the lemon juice, but this is normal.
Step 4: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add to the wet mixture.
Step 5: Fold in the old-fashioned oats and white chocolate chips, if using. The cookie dough will be thick and slightly sticky.
Step 6: Drop about 2 tablespoons of dough per cookie onto prepared baking sheets, spacing them 2 inches apart. Gently flatten the tops.
Step 7: Bake for 10 to 12 minutes, or until the edges are golden and the centers are just set. Let cool on the baking sheet for a few minutes before transferring to a wire rack.
Step 8: While the cookies are cooling, whisk together the powdered sugar, lemon juice, and lemon zest in a small bowl until smooth.
Step 9: Once the cookies are completely cool, spoon or drizzle the glaze over the tops of each cookie. Allow to set before serving.
