Preheat your oven to 325 degrees Fahrenheit (165 degrees Celsius). Grease two to three smaller bread pans with cooking spray.
In a small bowl, combine 1 teaspoon cinnamon and 1/2 cup sugar to make the cinnamon-sugar mixture. This is optional, you can just grease loaf pans and skip the cinnamon sugar mix.
Sprinkle the prepared greased loaf pans with the cinnamon-sugar mixture.
In a separate large mixing bowl, mix together oil, sugar, eggs, milk, and vanilla until well combined.
Stir in dry ingredients, cinnamon, baking powder, box of butterscotch pudding mix (or caramel whichever flavor you are using), baking soda, flour, and salt until the batter is smooth.
Divide the batter evenly between the prepared bread pans.
If any remaining cinnamon and sugar mixture remaining, feel free to sprinkle some over the tops of the batter in the pans.
Bake in the preheated oven for 45 to 60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
