Preheat the oven to 350 degrees and grease a 9×13 inch baking pan or 2 round cake pans.
In a large mixing bowl, beat the sugar, eggs, oil and vanilla for 2 minutes until it is creamy.
In a separate large mixing bowl whisk together the remaining dry ingredients.
Add ⅓ of the flour mixture and ⅓ of the water at a time to the sugar mixture and whisk until just combined before adding another ⅓ until all ingredients have been added and combined, don't over whisk mixture.
Pour batter into baking pan and bake for 35-45 minutes, until a tooth pick comes out clean.
Let cake cool in the pans.
Top with your favorite frosting and enjoy your whole grain cake.
