Preheat the oven to 325 degrees F (165 degrees C). Grease two 5x9 inch loaf pans; sprinkle bottoms with cinnamon sugar.
Combine flour, sugar, pudding mix, cinnamon, baking powder, baking soda, and salt in a large bowl. Combine milk, oil, applesauce, eggs, and vanilla in a separate bowl; stir into flour mixture until smooth. Divide batter between the prepared pans.
Bake in the preheated oven until a toothpick inserted into centers comes out clean, about 1 hour.
