Preheat oven to 350 degrees.
Grease a 9" baking pan with coconut oil or butter. Add 1 Tbsp. white vinegar to 1 cup of organic milk (set aside for 5 minutes).
Combine all dry ingredients in a stand mixer (this one is what I use) and mix for 30 seconds, until all are combined.
Add wet ingredients and blend for 2 minutes.
Spoon the batter on a greased pan and smooth out with a spatula.
Bake at 350 for 45-55 minutes or until a toothpick comes out clean and the cake has risen a bit. While cake is baking prepare cream cheese frosting.
Dust with cocoa powder (optional).
