All about Old-Fashioned Iced Oatmeal Cookies

You know the packaged Iced Oatmeal Cookies you can buy at the store?  Well, you can quickly and easily make them yourself and will be pleased with the outcome.  These cookies with their old fashioned style and cozy spice flavor.  They’re topped with a light coating of vanilla icing that sets overtime, making them perfect for stacking and gift giving. 

One trick to making the perfect Old-Fashioned Iced Oatmeal Cookies is to pulse the oats.  This is an extra step but does completely transform your cookies.  By pulsing them just a few times, it results in an excellent texture and perfect cookie crumble.  But if you really don’t have time for this step, just use part quick oats about ½ cup and then the remaining 1 cup use old-fashioned oats and to achieve similar results to having pulsed the oats.

This is a soft cookie dough and will over-spread in the oven unless you chill it.  Chill the cookie dough for about 45 minutes in the refrigerator before baking.  Another trick is to use a cookie scoop.  A cookie scoop prevents mess and helps ensure all cookies are the same size and shape.  For these cookies and most cookies, we recommend the medium cookie scoop which hold about 1 ½ tablespoons of cookie dough.  The cookies do spread nicely when baking so we do recommend only 8-9 cookies per baking sheet.
