These cookies are inspired by the classic old-fashioned iced oatmeal cookies — but softer, chewier, and even more delicious. The outside has a delicate crisp edge, the inside stays soft and buttery, and the simple vanilla glaze gives them that nostalgic bakery look.

Perfect for holidays, cookie trays, gifting, or any day you want a comforting homemade treat.
