Preheat a waffle iron on high.
In a medium bowl, mix the almond milk and the apple cider vinegar. Set aside for 5 minutes.
In a large bowl, add the flour, baking powder, ground flaxseed, cinnamon, pumpkin pie spice, and salt. Whisk until well combined.
To the bowl with the almond milk, add the pumpkin puree, coconut oil, maple syrup, and vanilla and whisk together until well combined. Pour the wet ingredients into the bowl with the dry ingredients and stir until just combined. Don’t overmix.
Spray (make sure your spray doesn’t have propellants or it will ruin your non-stick waffle iron) or brush oil on hot waffle iron. Scoop batter onto your waffle iron and cook until golden brown and the edges are crisp (I cook mine for about 5 minutes). Serve hot with pure maple syrup and whatever toppings you like! Enjoy!
