Grandma's Sour Cream Cookies

I made these in memory of the two year anniversary of Gramzy's passing. These are probably my favorite cookies ever, and I am so sad that I can't get them to taste the same as Grandma's. I usually mix it all by hand, maybe I should try using a beater. I guess I just need to keep practicing.

Ingredients:

3 cups flour
1 tsp baking powder
1/2 tsp baking soda
1 tsp vanilla
1 cup margarine
1 1/2 cups cugar
2 eggs
1 cup sour cream
chocolate chips

Directions:

Mix dry ingredients, set aside. Beat margarine and sugar, add eggs and beat until light and fluffy. Add sour cream and vanilla, beat until smooth. Gradually add dry ingredients, mix until smooth. Add chocolate chips. Drop 2" apart on lightly greased pan. Bake at 375 for 10-12 minutes.
