Leftover Oatmeal Cookies

Oatmeal is one of my favorite things for breakfast.  I especially love to fancy it up with dried fruit, honey, peanut butter, you name it!  I made a bunch of oatmeal for myself and the kids, but found myself with about a cup’s worth of leftover oatmeal.  I figured there had to be a way I could turn that into cookies.  After a few rounds of testing, I am excited to share with you the recipe for Leftover Oatmeal Cookies.

These have a soft, fluffy texture on the inside. But, the crispy outside confirms their placement in the world of cookies.  You can see I used fresh blueberries since that’s what I had on hand from the morning’s breakfast.

But, if you wanted to use dried berries or some other fruit, it’s totally up to you.  But, whatever you do, don’t skip the lemon glaze! I am a huge fan of anything lemon and it adds a little zip of sweet/tart to make these extra crave-worthy.  Too, it’s just an added touch of sweetness that these little nuggets need.

I also added some lemon zest to finish them off because it’s winter and we’ve got a ton of lemons coming off our tree in the backyard.

What’s your favorite oatmeal combo?  I hope you enjoy these cookies and making them with your own oatmeal flair <3
