December 23…we are almost to Christmas, but I couldn’t resist sharing just one more Christmas cookie recipe!

These old fashioned iced oatmeal cookies are everything you want in a Christmas cookie. They’re easy to make, they are sweet, cinnamon-y, and perfectly crisp. Sweet icing in a crackly pattern on top is the finishing touch.

These easy iced oatmeal cookies are gluten free and vegan, and they remind me of cookies that I had when I was a kid. They’re like the cookies you might have packed in your lunch or eaten as an after school snack.

The secret to the crisp, perfect texture of these cookies is in the oats. Rather than just adding oats to the cookie dough, you need to pulse them in the food processor first.

You don’t want to create a super fine flour – just a coarse oat flour will do the trick. Using fresh ground oat flour will give these cookies the perfect crisp texture.

What kind of icing is on these oatmeal cookies?

This is the simplest icing ever! Take a cup of powdered sugar and add a tablespoon of water, then mix. Add a tiny bit of water at a time until the icing is like a thick glaze. This will create the perfect crackly top on the cookies.

How do you get the icing to look crackled?

Once the cookies are fully cool, dip just the tops into the icing. Don’t fully submerge them, just lightly dip the cookies so that the icing doesn’t get into all the cracks and crevices on the surface of the cookies.

Yes, you can freeze this dough! Just use a cookie scoop to scoop the dough onto a cookie sheet, and freeze the dough balls until firm. Once frozen, place the cookie dough in a freezer bag. It should stay fresh in the freezer for up to three months.

Can I use oil instead of vegan buttery spread?

I haven’t tried that, but I don’t recommend it. I think it would change the texture of these cookies. Use whatever buttery spread works for your diet, or if you can have dairy, regular butter is also a great choice.
