Preheat the oven to 350ºF and line two 8-inch cake pans or three 6-inch cake pans with parchment paper and then grease with coconut oil.
In a large mixing bowl, combine the almond flour, tapioca flour, baking soda, baking powder, salt, coconut sugar, and cacao powder. Whisk all dry ingredients together.
2¼ cups (220g) blanched almond flour, 1¼ cups (183g) coconut sugar, ⅔ cup (75g) tapioca flour, 1½ teaspoon kosher salt, 1 teaspoon baking soda, 1 teaspoon baking powder, 1 cup (100g) cacao powder
In a separate mixing bowl or large liquid measuring cup, whisk the almond milk, applesauce, coconut oil, and melted chocolate. If the coconut oil or chocolate firms up at all, warm the mixture for about 20 seconds to re-liquify the mixture. Whisk in the nut butter, eggs, and vanilla extract.
⅔ cup (5.3 oz) non-dairy milk of choice, ½ cup (122g) unsweetened applesauce, ⅓ cup (67g) refined coconut oil, ⅓ cup (2 oz) Hu Kitchen Chocolate Gems, ¼ cup (64g) creamy almond or cashew butter, 2 large eggs, 2 teaspoons pure vanilla extract
Pour the wet ingredients into the mixing bowl with the dry ingredients and stir until fully combined.
Divide the batter between the prepared pans. Bake for 18 to 30 minutes, depending on the size of the cake, or until a toothpick inserted into the center comes out clean and the top springs back when pressed. Let cool completely before removing from the pan.
