1) Preheat oven to 350°. 2) Mix oil and sugar until well blended. 3)Add eggs and vanilla; stir just until blended. 4) Mix all dry ingredients in a separate bowl. 5) Stir dry ingredients into the oil/sugar mixture. 6) Pour into greased 9 x 9 square pan. 7) Bake for 20 minutes or until sides just start to pull away from the pan. 8) Cool completely before cutting. 9) Note: I usually double the recipe and bake in a 9 x 13 pan. If you double the recipe, you will need to cook longer than 20 minutes.
