Oatmeal Sandwich Cookies

This recipe makes a huge batch, about 3 dozen to be exact. That might be enough to feed the whole neighborhood.

Or just me.  🙂

If you generously fill the sandwich cookies with filling, you may run a little short, but the cookies are quite good eaten plain.

The cookies are just a little soft and chewy and flavored with cinnamon and nutmeg. They are made with shortening instead of butter which really helps them hold their shape and gives them a wonderful soft texture. I find they taste just like Little Debbie Oatmeal Cream Pies which were one of my favorite treats as a child.

I love to pile them high on a plate and watch them disappear.
