. Preheat your oven to 425°F (220°C) and line your muffin tin with cupcake/muffin liners.
Make vegan buttermilk by adding two tablespoons of lemon juice to 1 ¼ cups of plant-based milk. Set aside for ten minutes, it should appear lumpy.
In a medium-sized bowl, whisk together vegan buttermilk, arrowroot starch, pumpkin puree, mashed bananas, agave, vanilla extract, and oil. Set aside.
In a separate, large bowl, whisk together sifted spelt flour, salt, baking soda and pumpkin spice.
Slowly incorporate the wet ingredients into the dry ingredients. Gently fold mix ins into your batter if you so desire.
Scoop the batter into your lined muffin tin, filling them almost all the way up.
Bake the muffins in your oven for 7 minutes at 425°F (220°C) and then reduce the temperature to 350°F (180°C ) and bake for 20-23 minutes or until a toothpick placed in the center comes out clean.
Remove your muffin tin from the oven, allow the muffins to stay in the muffin tin for 10 minutes then place them on a wire rack to cool completely. Enjoy!
