Maple Bar Doughnut

Maple bar is an unusual American doughnut originating from the West coast and usually associated with California. The doughnut is rectangular in shape and topped with a maple glaze. Inside, it can be left as it is or filled with cream or custard.

The dough is often made with a mix of flour, egg yolks, vanilla, shortening, baking powder, salt, sugar, water, and yeast, while the maple icing contains powdered sugar, salt, vanilla, and maple extract. These doughnuts have many variations, so they're often topped with nuts or bits of bacon.
