Preheat oven to 350* F. Grease two 8-inch round cake pans and insert a parchment circle into the bottom of each pan.
In a medium bowl, combine the flour, baking powder, baking soda, and salt. Whisk to combine.
2 ⅔ Cups All-Purpose Flour, 2 ½ teaspoon Baking Powder, ¼ teaspoon Baking Soda, ½ teaspoon Kosher Salt
Into a large bowl, combine sugar, non-dairy milk, melted non-dairy butter, lemon zest, lemon juice, and vanilla extract. Whisk well to combine.
1 ½ Cups Granulated Sugar, 1 ½ Cup Non-Dairy Milk, 9 tablespoon Non-Dairy Butter, melted and cooled, Zest of 2 Large Lemons, 1 tablespoon Lemon Juice, 2 teaspoon Vanilla Extract
Add the dry ingredients to the wet ingredients and whisk to form the batter. Then, switch to a spatula and fold the batter a couple of times to ensure everything is combined.
Divide the batter between two prepared 8-inch round cake pans. If you have a kitchen scale, it is about 22 ounces per pan. Use a spatula to spread the batter evenly.
Bake the lemon cake layers in a 350* F oven for 30-33 minutes or until a toothpick inserted into the center of a cake comes out clean.
Allow the cakes to cool in their pans for 30 minutes, then turn them out of their pans onto a parchment-lined baking sheet to cool completely before frosting.
