Soft, chewy lemon oatmeal cookies made with fresh lemon zest and topped with a creamy vanilla bean glaze. These cookies come together in one bowl and are ready in about 30 minutes, perfect for spring baking. If you love a classic oatmeal cookie with real citrus lift, this is the one to bake.
Preheat oven to 350℉ and line a cookie baking sheet with parchment paper.
Beat butter on medium-high speed until light and fluffy. Add both sugars and beat for another minute.
Add eggs, one at a time, mixing well after each addition. Scrape sides and bottom of the bowl.
Add vanilla extract, flour, baking soda and salt. Mix it in on low speed just until incorporated.
Add oats, while still on low speed, just until incorporated.
Add lemon zest and mix until evenly mixed throughout.
Scoop cookie dough and roll about an inch sized balls. Place cookies on parchment paper, about two inches apart. Press very lightly to flatten cookies just a little bit.
Bake for 9-11 minutes.
While cookies are baking, prepare the glaze. Scrape vanilla bean seeds into heavy cream and mix well. Warm up heavy cream but not too hot. Add powder sugar to a shallow bowl and add lemon zest. Whisk in heavy cream mixture slowly, until all smooth. Drizzle warm cookies.
Notes
No whole vanilla bean on hand? Use 1 tsp vanilla bean paste or just 1 tsp pure vanilla extract in the glaze instead.
Old-fashioned oats are best here. Quick oats or instant oats will work in a pinch, but the texture will be changed, finer and less chewy.
Make sure butter is fully at room temperature before creaming, not melted, so the dough doesn't spread too much.
Drizzle the glaze while the cookies are still warm for the smoothest, glossiest finish.
