Oatmeal Cream Pies

A yummy switch from the usual chocolate treats I make.  I saw this on a friend's facebook page.

Oatmeal Cream Pies
From Blooming on Bainbridge

Oatmeal cookies:
1 1/4 c softened butter
1 c brown sugar, packed
1/2 c sugar
1 egg
2 t vanilla
1 t soda
1/2 t salt
1/4 t cinnamon
1 1/2 c flour
3 c oats

Preheat oven to 375.  Beat butter and sugars until creamy.  Add egg and vanilla, mix well.  Spoon flour into measuring cup and level with a knife.  Combine dry ingredients; mix well.  Add to butt mixture and blend well.  Drop by rounded tablespoon 2 inches apart on cookie sheet lined with parchment.  Bake for 10 min and cool for 2 min in pan.  Finish cooling on rack.

Cream filling:
1/2 c softened butter
2 c powdered sugar
1-2 T whipping cream

Combine all ingredients and beat on low until mixed.  Continue beating on high until light and fluffy.
Spread 1 T of cream between 2 cookies.

*These are quite delicious.  The only thing I did different from the recipe was that I used margarine instead of butter.  Mine didn't seem to spread as much as pictured in the original recipe, but still tasted delicious.  I also used cooking spray instead of parchment paper.
