Preheat oven to 350°F and lightly grease donut pans.
In a small bowl combine the all-purpose flour, baking powder, baking soda, salt, cinnamon and nutmeg.
In a medium bowl whisk the milk, melted Biscoff cookie butter, melted butter, granulated sugar, brown sugar, eggs and vanilla extract until well combined.
Gently fold the dry ingredients into the wet mixture until just combined. The batter will be thick and lumpy. Do not over mix!
Use a piping bag or a zip-top bag to pipe each donut ring 2/3 full. Do not fill to the top, the donuts will rise as they bake.
Bake the donuts for 10 minutes. Allow to cool in donut pans for 5 minutes then unmold and finish cooling on a wire rack.
Biscoff Glaze
Melt the Biscoff cookie butter in the microwave in 10-15 second intervals.
Dip cooled donuts into the melted cookie butter then top with Biscoff cookie crumbs. Allow glaze to set before eating.
Notes
Weigh your ingredients using a kitchen scale! Measuring ingredients by volume is not accurate.
Butter: I recommend using unsalted butter. You can use salted butter, just be sure to omit the 1/2 tsp salt.
These Biscoff Donuts are best enjoyed the day that they're made but can be stored in an airtight container for up to 2 days at room temperature or up to a week in the fridge.
