Prepare two 8" round cake pans by greasing and inserting a parchment circle into the bottom of each pan. Preheat oven to 350*F.
In a medium bowl, combine flour, baking powder, baking soda and salt. Whisk to combine and set aside.
2 ⅔ Cups All-Purpose Flour, 1 tablespoon Baking Powder, ¼ teaspoon Baking Soda, ¼ teaspoon Kosher Salt
In a large bowl, combine granulated sugar, non-dairy milk, melted vegan butter, vinegar, and vanilla. Whisk well to combine. Then, add the dry ingredients and whisk to form the cake batter.
1 ½ Cup Granulated Sugar, 1 ½ Cup Non-Dairy Milk, 9 tablespoon Vegan Butter, melted, 1 tablespoon White Vinegar, 1 tablespoon Vanilla Extract
Divide the cake batter between the two prepared pans and spread out evenly with a spatula. If you have a kitchen scale, it will be 20 ounces of batter per pan.
Top each pan of batter with 3 tablespoons of strawberry preserves. Try to distribute it evenly across the batter. Then use a knife to gently swirl the preserves into the batter.
6 tablespoon Strawberry Preserves or Jam
Bake in a 350* oven for 31-33 minutes or until a toothpick inserted into the center of the cakes comes out clean. Then, allow the cake layers to cool completely before proceeding. (See Note)
