Better Than Grandma’s!

What do you get when you take my favorite oatmeal Cookie recipe and add a sugary glaze on top? Just about one of the best holiday cookies that certainly rival any of the frosted cookies up on the blog! 

Any of them would be the perfect addition to a Christmas dessert board but there’s something nostalgic about old-fashioned Iced Oatmeal Cookies that just brings an extra dose of warmth this time of year. 

Iced Oatmeal Cookies are made with chunks of oats and butter for a buttery, thick and chewy texture and flavored with brown sugar and cinnamon for the ultimate bite. They are then smothered in a simple 2-ingredient icing that sets up nicely making them stackable for gifts, potlucks, or a cookie exchange party.

Why This Recipe Works

• Quick and easy. An entire batch of homemade cookies from scratch made in 1 hour! 
• Double the batch. Easily make two or three batches and freeze half for another day!
• Taste and texture. Warm spices, sweet brown sugary goodness, and a buttery texture full of chunky oats.  
• Great for special occasions. There’s nothing wrong with naming a simple iced oatmeal cookie one of the best holiday desserts. We always come back to the classic recipes!

• Old-fashioned rolled oats: Love the texture of these oats. You won’t get the same from quick oats or instant oats because they absorb liquid differently. 
• Unsalted butter: Bring it to room temperature early enough so that it is nice and soft by the time you need to cream it. We’re using unsalted so we can control the amount added to the dough. Learn tips for how to soften butter quickly.
• Molasses: This is an optional ingredient used to give the iced oatmeal cookies an extra level of flavor. You can also do this with maple syrup if you prefer. If going with molasses, stick with dark molasses rather than the more intense blackstrap molasses. 
• All-purpose flour: For amazing texture, be sure to measure the flour accurately using a scale or the spoon and level method which I go through in detail for you. It’s a great tool to have for any baking recipe that uses flour.

Variations

There are a lot of ways to get creative with this simple concept! All you need to do is add the icing to any one of the following cookie recipes:

You can even sandwich the ice cream between two cookies and make a version of these oatmeal cream pie cookies!

• Pulse the oats. First things first, we want textural cookies so we’re pulsing only a cup of the oats until they are broken. The rest we leave whole. We don’t want to turn it into flour so be careful not to pulse it too long.
• Mix the wet ingredients. In the bowl of a stand mixer using the paddle attachment, or a large mixing bowl with an electric mixer, cream the butter, brown sugar, and granulated sugar until pale and smooth. Mix in the eggs, vanilla extract, and molasses until combined. 
• Add the dry ingredients. To the same bowl, add 1/2 of the flour, salt, baking soda, baking powder, and cinnamon. Mix until just combined and then add in the remaining flour, pulsed oats, and the rest of the whole rolled oats to the mixture. 
• Scoop and bake. Use a medium cookie scoop to scoop the dough onto prepared baking sheets. I like to use parchment paper or a silicon mat for this. Bake for 10 minutes in a preheated 350°F oven until the edges are just lightly golden brown. For softer cookies take them out a little early, and for crispier cookies, let them bake a little longer.
• Make the icing. While the cookies are cooling on the wire rack, whisk together the powdered sugar and milk in a bowl. Set it aside until the cookies are completely cooled. Adding the glaze too soon will make it runny.
• Add the glaze. Add about 1 teaspoon of glaze to each cookie and then use a knife or the back of a spoon to spread it on top. Allow it to set until the icing has hardened. Enjoy!

Expert Tips

• Easy cleanup. Icing one cookie at a time and working over parchment paper will help with the cleanup. Whether you’re drizzling the frosting or using the cookie to dip it right in there, you’ll want something to catch any excess drips. 
• Instant oats. I know I said they’re not the same (and they’re not) but you can use them if that’s what you have. You’ll still want to pulse them a little bit too!
• Icing consistency. The thicker your icing, the easier it sets. Adjust the amount of powdered sugar (or milk) if necessary. This gingerbread icing will work too!
• Make ahead. There are a few ways you can do this. One is to make the cookie dough and chill it in the fridge for up to 4 days then bring it to room temperature just before baking. You can also freeze the cookie dough and if you aren’t experienced in how to freeze cookie dough, I’ve got the best tips for you.

Storing

Keep iced oatmeal cookies covered in an airtight container at room temperature for up to 3 days. If not covered, they will dry out!
