This recipe may seem absurd, but it's definitely worth a bite (at least). The rich nougat and caramel filling coated in chocolate that makes a Mars bar takes on a whole new meaning when dredged in a sweetened crust.
In a large bowl, mix the flour, baking powder, sugar, and salt together. In a small bowl, whisk the milk and the egg together and add to the dry ingredients. Stir until smooth.
Heat the canola oil to 370 degrees.
Dip the bars in the batter and carefully place in the hot oil (work in batches 3-4 at a time). Cook until lightly browned and then flip and brown the other side, 3-4 minutes in total. Remove to a paper towel-lined plate. Repeat with remaining bars. Dust very lightly with powdered sugar.
