Prepare your flax egg and place it in the fridge to set before gathering your other ingredients.
In a large bowl mix together your dry ingredients: flour, coconut sugar, pumpkin spice, baking soda, baking powder, and a pinch of salt. Mix to combine.
In a smaller bowl, you want to mix together your wet ingredients until combined: pumpkin puree, vanilla essence, melted coconut oil, oat milk, and flax egg.
Add your wet mixture to your dry mixture. Mix until combined but do not go overmix.
Your mixture will look thick but this will help make them nice and thick.
Place a non-stick pan on the stove at medium heat. Let it get nice and hot. Add some coconut oil to the pan and add roughly 1/2 cup of batter to the pan.
Use the back of the measuring cup to smooth out your mixture into the roundest shape possible.
Because your pancakes will be thick, you need to let them cook properly, a good 3-4 minutes per side on low-medium heat.
