Oatmeal-Chocolate Chip Cookies

Here's a cookie recipe from Marianne/from her friend Deborah.

1 c. margarine (soft)
1.5 c. brown sugar
2 eggs
1 tsp. vanilla
1.5 c. flour
2.5 c. Quaker Old Fashioned Oatmeal
1.5 tsp. baking soda
½ tsp. of baking powder
12 oz. semi-sweet chocolate chips
1.5 c. chopped nuts (optional)

Preheat oven to 350. Use an electric mixer to beat the butter and sugar together; add in eggs and vanilla and continue to beat until creamy. Add the flour, baking soda, and baking powder and beat until well blended. Add the oatmeal and chocolate chips (you can keep using the electric mixer or do this last part by hand if you prefer). Drop by the spoonful onto cookie sheet. Bake at 350 for 12-15 minutes or until edges brown lightly. Cool on pans and transfer to racks to cool thoroughly.
