First, preheat oven to 350°F. Afterward, grease bottom and sides of all the pans you are going to use with butter or shortening. Do not forget to add a little flour as well. You can also use cooking spray with four in it, which we love!
In a small bowl, mix all dry ingredients for the cake batter: flour, baking soda, baking powder, and salt. Set it aside.
Grab your stand mixer and put the butter and granulated sugar inside the bowl. You could also use a hand mixer, or you could even do it by hand but it will take forever! Beat it well until it becomes a fluffy mixture of goodness.
In a small container, mix the milk and vanilla extract together.
Stop the mixer a moment and sift in a ⅓ of your dry ingredients, followed by a ⅓ of your liquids and an egg at a time. Incorporate in between on medium speed. Do not forget to add the final fourth egg!
Once everything is well incorporated, beat two more minutes on high and pour the same amount into all pans. You could measure this in order to make it as accurate as possible.
Bake for 25 minutes and check the center with a toothpick. If it comes out clean, then they are done! Take them out before they burn! But if not, leave them for another 5 to 10 minutes.
Allow 10 minutes for them to cool outside the oven and take them out of the mold to place them into cooling racks. Leave them be for a good full hour before attempting assembly. If they are still warm, your cake will not be as stable.
To speed this up, you could place them inside the fridge!
