Simple, but definitely delicious.

Ok, before we get to today’s recipe, let’s talk about something important for a minute.

Are you a chewy or crispy cookie person? Don’t answer right away, take a minute and think about it.

I’m usually happily a chewy cookie lover, but today’s cookies changed my mind and they might change yours too. I think you know where this is headed.

For all of my crispy cookie-loving friends, do I have a treat for you today!

These cookies are thin and crispy, full of butter, sugar, and lots of oatmeal. We are using more regular white sugar than brown sugar to keep the cookies from getting too soft. We want the flavor from the brown sugar, but not the extra moisture. All of these ingredients combine to make some delicious cookies.

I’ve been making these cookies for several years and we think they are pretty great. But a couple months ago I realized they were missing something…icing. They needed icing.

Mr. Sam was more than a little skeptical when I told him I was going to ice these cookies, but once he tried the final product he was a fan of these Old Fashioned Iced Oatmeal Cookies.
