Preheat the oven to 350°F. Lightly grease two or more donut pans.
In a large bowl, mix together pumpkin purée, vegetable oil, eggs, vanilla extract and sugar. In a medium bowl, whisk together pumpkin pie spice*, salt, baking powder and all purpose flour.
Add the flour mixture into the pumpkin mixture and mix until just combined.
Fill your donut pan, each well being ¾ full. The easiest and cleanest way to do this is by placing your batter into a pastry bag and piping it into each donut well.
Bake the donuts for 14-17 minutes until a cake tester or toothpick comes out clean.
Cool in the pan for 10 minutes before removing and placing on a cooling rack. Top once cooled.
To make the topping:
Heat Cookie Butter in the microwave for 30 seconds. Dip the top of the donuts in one by one and dry on cooling rack. Sprinkle on crushed Lotus Biscoff Cookies.
