In a large bowl, mix in the oil and sugar, using a hand mixer, in medium speed (you can also mix by hand)
Add the eggs one at a time, gently, mixing in low speed
Then, add 1/3 of the dry ingredients mixture to the eggs mixture, and fold by hand with a spatula to combine. Add half of the water, and fold to combine. Add the second third of the dry ingredients, and fold to combine. Add the last of the water, and fold to combine. Add the last third of the dry ingredients, and fold to combine.
Pour the batter into the greased pan, and bake bake until a cake tester/toothpick inserted to the middle comes out lightly crumbly to clean (about 35-40 mins)
Move the cake pan to a cooling rack and let it cool for about 10 mins, then remove the cake from the pan and let it cool in the rack
