Preheat oven to 350* F. Prepare two 8-inch round cake pans by greasing them well with shortening and inserting parchment circles into the bottom of each pan.
In a medium bowl, combine flour, baking powder, baking soda, salt, cinnamon, ginger, and allspice. Whisk to combine.
2 ⅔ Cup All-Purpose Flour, 2 ½ tsp Baking Powder, ½ tsp Kosher Salt, 1 Tbsp Cinnamon, 2 tsp Ginger, ½ tsp Allspice, ¼ tsp Baking Soda
In a large bowl, combine brown sugar, non-dairy milk, melted vegan butter, vinegar and vanilla. Whisk well to combine.
1 ½ Cup Light Brown Sugar, packed, 1 ½ Cup Non-Dairy Milk, 10 Tbsp Vegan Butter, melted and cooled, 1 Tbsp White Vinegar or Lemon Juice, 2 tsp Vanilla Extract
Add the dry ingredients into the wet ingredients and whisk to form the batter. Then, add the chopped apples and use a rubber spatula to fold them into the batter until they are evenly distributed.
1 Medium Apple, peeled, cored, and cut into ½-inch cubes
Portion the batter evenly between the prepared cake pans and spread the batter out evenly. Bake in a 350* F oven for 35-38 minutes or until a toothpick inserted into the center of a cake comes out clean. Allow to cool completely before decorating. See note!
