Ultimate 5-Minute Microwave Oatmeal Cookie: The Quickest Single-Serving Treat (Eggless!)
Do you ever get that intense craving for a warm, freshly baked oatmeal cookie, but the thought of preheating the oven, mixing a whole batch, and waiting for it to bake feels like too much effort? What if we told you that delicious, chewy goodness could be yours in under 5 minutes? Yes, you read that right!

If oatmeal chocolate chip cookies are your absolute favorite, but your schedule (or energy levels) rarely allow for a full baking session, then this incredible Microwave Oatmeal Cookie is about to become your new best friend. It’s a game-changer for anyone who loves instant gratification when it comes to dessert.
This recipe delivers an utterly delicious, eggless oatmeal cookie for one, ready from the first stir to the first bite in truly less than 5 minutes. Imagine: a mere two minutes of prep and less than a minute of cook time in your microwave! Whether you prefer the classic sweetness of chocolate chips, the fruity chewiness of raisins, or even the delightful combination of chocolate-covered raisins, this cookie is perfectly adaptable to your cravings.
It’s the quintessential single-serving dessert for those moments when you desire something nutty, wonderfully comforting, and deeply satisfying without the hassle of turning on the oven. This is especially true on hot days when the last thing you want is more heat in your kitchen, or when you live in a smaller space where a full baking spree isn’t always practical.
This delightful oatmeal mug cookie shares some similarities with my popular Microwave Chocolate Chip Cookie, but with the added wholesome texture and flavor of quick oats. To compensate for the oats’ liquid absorption and to ensure a tender, moist cookie (rather than a dry, crumbly one), I’ve carefully adjusted the milk content. This subtle tweak helps maintain a perfect balance, resulting in a cookie that’s wonderfully chewy, yet still satisfyingly tender—a characteristic often sought after in traditional oatmeal cookies.
For those who love a bit of a twist, you can even venture into making Peanut Butter Oatmeal Chocolate Chip Cookies. Simply use my beloved Microwave Peanut Butter Cookie as your foundational base, then incorporate quick oats and your preferred chocolate chips. The possibilities for customizing your instant cookie are endless!
