Preheat oven to 400 degrees
Lightly grease a doughnut baking tray (I used coconut oil to grease it)
Mix the all-purpose four, brown sugar, salt, cinnamon together
Make a well in the dry mixture and add the egg, melted butter, milk, and vanilla extract, and mix well with the dry mix
Fold in the bacon crumbles
Spoon into Doughnut baking tray and bake for 10 minutes
Make the drizzle by combining milk, confectioners sugar, cinnamon, and vanilla together
Drizzle on top of doughnuts - and sprinkle bacon crumbles on top and enjoy!
