These Iced Oatmeal Cookies contain a tasty spice combo and remind me of Christmas with snowy white icing that pops against the brown oatmeal base.

Iced oatmeal cookies are one of my most beloved cookies. They remind me of the fall and Christmas holiday seasons. As a little girl, I ate these cookies by the handful, first licking off the icing before enjoying the chewy oatmeal base. Growing up, they were my favorite homemade cookie even though we had the store-bought variety, too. It’s been a minute since I had one last, but I’m glad to see them come full circle. These iced oatmeal delights can easily be enjoyed year-round and in the comfort of your own home with this tasty recipe.
The idea of baking with old-fashioned oats became popularized when Quaker Oats first published an old-fashioned oatmeal cookie recipe on its packaging. Their goal was to encourage and inspire customers to bake using their oats. Since then, this cookie has become a perennial favorite. The cookies made from this recipe have soft centers, with crisp, chewy edges, and offer a cozy spice flavor balanced with a creamy vanilla icing that will melt on your tongue.
Are Iced Oatmeal Cookies Healthy?
These homemade iced oatmeal cookies are considered healthier than store-bought alternatives since they are free from the chemicals and preservatives used to extend the shelf life of store-bought varieties. Plus, the oats are a great source of fiber and protein.
This recipe can be easily modified to fit specific dietary needs, too. For example, you can replace the all-purpose flour with a gluten-free flour (King Arthur makes a great one), or almond flour. For a dairy-free option, you can opt for a lactose-free dairy substitute. Kite Hill and Miyoko’s make great vegan dairy products, using high-quality organic ingredients. To make an egg-free recipe, mix 1 tablespoon of chia seeds with 2 1/2 tablespoons of water to create one egg replacement.
variations
You can always mix in more goodies, creating plenty of variations for these cookies! Try adding raisins or toasted walnuts for added flavor and texture, or mix in some creamy cashew or peanut butter for a nutty twist. You can also add a few semi-sweet or dark chocolate chips, or shredded apples. Whatever you decide to do, have fun with it! Cooking is a creative outlet for many and experimenting is all part of the process.

FAQs & Tips
After baking, you can store your iced oatmeal delights in an airtight container or zip-top bag in the refrigerator for 5 to 7 days. You can also spoon or scoop the unbaked cookie dough onto a lined sheet pan and freeze, and then transfer the frozen cookies to a zip-lock bag. These will keep in the freezer for up to 3 months.
Ensure the icing is mixed to perfection and free from clumps by first sifting your powdered sugar. This extra step is one you don’t want to skip.
Avoid fully dunking the cookies in icing. You want to kiss the cookies with the icing to get a crackly top as the icing sets. Also, allow enough time for the icing to dry for an extra delicious bite.
