These are not the oatmeal cookies you are probably used to.

They are soft and not flat.
You can make these without chocolate chips, but they are a nice addition.

Preheat your oven to 350 degree Fahrenheit oven.
Grease some cookie sheets.

1/2 cup(1 stick) unsalted butter, softened
2 Tablespoons(1/8 cup) vegetable oil
1 cup brown sugar
1 egg
6 Tablespoons(3/8 cup) sour cream
2 teaspoons vanilla extract
2 cups rolled oats
1/2 teaspoon baking soda
1/2 teaspoon cinnamon
1/2 teaspoon salt
1-1/2 cups flour
1 cup chocolate chips
1 cup chopped nuts-optional

In a small bowl whisk the flour, salt, cinnamon,and baking soda.
Set aside.
In a large bowl, cream, the sugar, butter, and oil.
Add the egg and beat well.
Stir in the sour cream and vanilla extract.
Stir in the oats.
Add the flour mixture. Mix well.
Add the chocolate chips.
Let the dough rest for 15-30 minutes. Letting it rest is important. The oats will absorb moisture from the rest of the dough.

Use a tablespoon or large cookie scoop to put cookies on the sheets.
Bake the cookies for 12 minutes or until they are light brown.

Remove to a cooling rack.

Makes 3-4 dozen cookies.
