Prepare either 3 6" cake pans or 2 8" cake pans by greasing them well and inserting parchment circles into the bottom of the pans.
Preheat Oven to 375* F.
In a medium bowl, combine flour, baking powder, baking soda and salt. Whisk to combine.
1 ½ Cups All Purpose Flour, 2 teaspoon Baking Powder, ¼ teaspoon Baking Soda, ½ teaspoon Kosher Salt
In a large bowl, combine non dairy milk, sugar, canola oil, lemon juice and salt. Whisk well.
1 Cup Non Dairy Milk, 1 Cup Granulated Sugar, ⅓ Cup Canola Oil, 2 teaspoon Lemon Juice, 2 teaspoon Vanilla Extract
Add the dry ingredients into the wet ingredients and whisk to form the batter.
Divide the batter into prepared cake pans and spread evenly to the edges.
Bake in a 375*F oven for 16-19 minutes or until a toothpick inserted into the center of the cake comes out clean.
Allow to cool for 30 minutes, then line a baking sheet with parchment and turn the cakes out onto the baking sheet.
Place the baking sheet with the cakes on it into the freezer to chill for 1 hour.
