Vegan Sugar and Spice Muffins

Preheat the oven to 350 degrees F (175 degrees C). Grease a muffin tin with cooking spray.

Mix flour, baking powder, pumpkin pie spice, and salt together in a small bowl.

Whisk sugar, avocado oil, and aquafaba together in a bowl until sugar is dissolved. Pour in flour mixture; mix until evenly incorporated.

Spoon batter into the prepared tin, filling each cup halfway full.

Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes.

Combine sugar and cinnamon in a shallow dish to make the topping. Remove hot muffins from the tin and dip in melted margarine; roll in cinnamon sugar to coat. Serve warm.
