Oatmeal Chocolate Chip Cookies

I've had really bad luck baking homemade cookies over the last year. They always taste great right out of the oven, but by the next morning, they're either way too soft, or rock hard. (Unless I made these.) Finally, I've found a cookie recipe that maintains its delicious texture day after day... it does not disappoint!

Oatmeal Chocolate Chip Cookies

1 c. butter or margarine
1 c. brown sugar, packed
1 c. sugar
2 eggs
1 tsp. vanilla
1.5 c. flour
1 tsp. baking soda
0.5 tsp. salt
3 c. oatmeal
1 bag chocolate chips

Preheat oven to 375 degrees.
In a large bowl, beat butter/margarine until light.
Add sugars; beat until fluffy.
Add eggs and vanilla, beat well.
Add flour, baking soda, and salt; mix well.
Stir in oatmeal and chocolate chips until thoroughly combined.
Drop by rounded tablespoonfuls onto a cookie sheet.
Bake 10-12 minutes or until cookies are just set. Do not overbake. (I used a silpat, and baked mine to perfection with 10.5 minutes in a 360 degree oven.)
Makes about 5 dozen.
