Apple Butter Cinnamon French Toast Sticks

1. Preheat the oven to 350° F. Line a baking sheet with parchment paper.2. Cut each slice of bread into 1-inch wide "sticks". 3. Add the butter to a skillet set over medium heat. Cook until the butter begins to brown, about 3-4 minutes. Remove from the heat and transfer to a heatproof bowl. Whisk in the milk, eggs, apple butter, and vanilla. Dunk each breadstick into the batter. Remove, allowing any excess to drip off back into the bowl. Place on the prepared baking sheet. Repeat with the remaining bread, try to use most of the batter.4. Mix the sugar and cinnamon together. Sprinkle half of the cinnamon sugar over the sticks. Bake for 10 minutes, flip, and sprinkle with the remaining sugar. Bake 10-15 minutes more, or until lightly golden. This step is optional if you'd prefer a less sweet option. 5. Serve warm with maple syrup for dipping and dunking.
