Preheat oven to 350 degrees and grease an 8 X 8 baking pan. (I used cooking spray).

Beat sugar, eggs, vanilla and butter on medium speed until well mixed.

Add in remaining ingredients, mix until all ingredients are well mixed in, but do not over mix. I mixed them with a wood spoon at this point to avoid over mixing.

Spread into prepared pan and bake until tooth pick comes out almost clean, about 22 minutes in my oven. Use middle rack.

Cool completely, and cut into 16 squares.
