Prepare the flax egg first. Mix ground flaxseed with 6 tablespoons of water in a small bowl, stir well, and let sit for 5 minutes to thicken.
Combine all dry ingredients in a large mixing bowl—whole wheat flour, baking powder, baking soda, pumpkin pie spice, and salt. Whisk thoroughly to ensure even distribution of the leavening agents.
In a separate bowl, mix the wet ingredients. Combine pumpkin puree, plant milk, maple syrup, vanilla extract, apple cider vinegar, and the thickened flax egg. Stir until smooth and well incorporated.
Pour the wet mixture into the dry ingredients and gently fold together until just combined. It’s crucial not to overmix—a few small lumps are perfectly fine and will give you fluffier pancakes.
Heat a non-stick skillet or griddle over medium heat. Test it’s hot enough by sprinkling a few drops of water—they should sizzle and dance.
Scoop about ¼ cup of batter for each pancake onto the heated surface. The batter will be thicker than traditional pancake batter—this is normal!
Cook until bubbles form on the surface and the edges look set, about 2-3 minutes. These pancakes take slightly longer than regular ones due to the moisture from the pumpkin.
Flip carefully with a spatula and cook for another 2 minutes on the other side until golden brown and cooked through.
Transfer to a plate and continue with remaining batter. If making a large batch, keep finished pancakes warm in a 200°F oven.
Serve immediately with your favorite WFPB toppings like fresh fruit, a drizzle of maple syrup, or a sprinkle of chopped nuts.
