Oatmeal Sandwich Cookies - cooking recipe

Ingredients

1 cup flour
2 cups oatmeal
1 cup margarine
1/4 cup sour cream
1/2 teaspoon baking soda
1/8 teaspoon salt
1/4 teaspoon vanilla
jam

Preparation

Mix the sour cream with the baking soda.
There are no directions as how to mix the dough but I always do this.
Mix the margarine well with the flour, salt and oatmeal. Add the sour cream mixture and vanilla.
The dough will be wet. Refrigerate for 2 hours.
Preheat oven to 350 degrees.
Roll the dough on a floured surface thinly, about 1/3 inch or a bit less. Cut into 2 1/2 to 3 inch rounds and place on cookie sheet.
Bake for 4-5 minutes, more or less, not letting the cookies brown too much. I have a fast cooking oven, you may need to allow 8 minutes.
Let cool on the pan a few minutes, then remove cookies from the sheet onto a rack.
When totally cooled, make sandwiches with a date filling, or jam.
I don't know the serving amounts, so guessing.
