Preheat oven to 350 degrees F.
In a bowl, combine dry ingredients - flour, baking soda, baking powder, cocoa powder, and salt. Whisk together until evenly combined.
Add in wet ingredients - olive oil, vanilla extract, almond milk, and apple cider vinegar. Stir until batter is evenly mixed.
Spray two 6-inch cake tins with coconut oil, then fill with batter. (If you don't have that size, feel free to make muffins or a larger cake! Just keep your eye on the cooking time - smaller portions will cook faster.)
Bake in the middle rack of the oven for 20-25 minutes. The best way to check doneness is to stick a toothpick in the cake - if it comes out dry, it's good to go.
Be sure to let cakes cool before frosting.
