1cupvegan chocolate chips or dark chocolate chunks
Prepare the flax egg by mixing 1 tablespoon flaxseed meal with 2.5 tbsp water, stir to combine and let sit for 15 minutes to thicken.
Preheat the oven to 375F or 190C. Line a 12-cup muffin pan with paper liners and lightly spray the liners with nonstick cooking spray or brush with melted coconut oil to prevent sticking.
Stir together the soy milk and apple cider vinegar. Set aside for 5 minutes to curdle.
In a medium bowl, whisk together the cake flour, whole spelt or whole wheat flour, cinnamon, ginger, nutmeg, baking powder, and salt.
In a large bowl, add the soy milk mixture, maple syrup, pumpkin purée, coconut oil, vanilla, and tahini and whisk until combined.
Mix the wet ingredients into the dry ingredients, mixing with a wooden spoon until just combined, taking care to not overmix. The batter should be lumpy, not smooth. Fold in the flax egg using a rubber spatula. Gently fold in 3/4 of the chocolate chips.
Spoon the batter into the lined muffin tins until they are filled almost to the top. Top the muffins with the remaining 1/4 of the chocolate chips.
Bake for 20-25 minutes or until the tops are lightly golden and a toothpick in the center comes out clean or with a few moist crumbs. Remove the muffin pan from the oven and let it rest for 10 minutes. Then remove the muffins from the the tin and cool completely on a wire rack.
To make one flax egg, mix 1 tablespoon of ground flax meal with 2 1/2 tablespoons of water. Stir and let sit for 15 minutes to thicken.
