Preheat the oven to 350 degrees. Combine first five ingredients in a bowl then add the lemon juice, oil, and vanilla, stir and the add water. Batter may be lumpy so stir until you have most of the lumps out. Grease and flour an 8-inch round cake pan or 9-inch square pan. Pour in batter. Bake for 30 minutes. Stick a toothpick in center of cake to test for doneness. When it comes out clean it is done. Take it out and cool. When it is cool you can frost it. Enjoy! This recipe can easily be doubled for a 9x13-inch cake.
Tip: If you need to turn your cake out of the pan make sure you grease and flour the pan then cut a piece of wax paper the same size as the bottom of the pan. Grease and flour the wax paper also and place in the pan with the flour side up. After the cake comes out of the oven let it cool about 10 minutes. Place a clean piece of wax paper on top of the cake then a wire cooling rack on top. Using oven mitts turn the cake over. It should come easily out of the pan. Let this cool completely. If you want to frost it as is then place a plate on top and tip the cake over. Remove the wax paper. (The sticky stuff on the wax paper is the best to eat. Do it right away!) Or you can cut the cake, for a themed or shaped cake, then frost.
