Preheat the waffle iron according to the manufacturer's instructions, about 5 minutes.

In a large mixing bowl, combine all-purpose flour, granulated sugar, baking powder, pumpkin pie spice, and salt. Whisk until evenly mixed, about 1 minute.

In a separate bowl, whisk together non-dairy milk, mild vegetable oil, light molasses, apple cider vinegar, and vanilla extract until smooth and fully combined, taking around 2-3 minutes.

Pour the wet mixture into the bowl with the dry ingredients. Gently fold together with a spatula, mixing until just combined. A few lumps are okay.

Lightly grease the preheated waffle iron with a small amount of oil or cooking spray to prevent sticking.

Pour about one-fourth of the batter onto the center of the heated waffle iron. Spread slightly if needed, being careful not to overfill.

Close the waffle iron and cook for 3-5 minutes until the waffles turn golden brown. Gently remove the waffles once finished.

Repeat with the remaining batter. Serve with your favorite toppings, such as maple syrup, berries, or vegan whipped cream.
