To begin, preheat your oven to 350 degrees F (175 degrees C). Then, grease and flour three 9-inch round or square cake pans. This will ensure that your cake doesn't stick and comes out perfectly.
In a separate bowl, sift together the flour, cinnamon, baking soda, and salt. This will help to evenly distribute the ingredients and ensure that your cake has a consistent texture and flavour.
In another bowl, beat together the sugar, oil, eggs, and vanilla extract until well blended. Gradually add the dry ingredients to the wet mixture until well mixed.
Divide the batter evenly among the prepared cake pans. Bake in the preheated oven for about 35 minutes or until a toothpick inserted into the center of the cake comes out clean. This will ensure that your cake is perfectly baked and ready to be enjoyed.
