Preheat the Dutch oven using 14 hot coals on top and 7 coals underneath, or preheat a home oven to 350°F.
In a medium bowl, whisk eggs, milk, vanilla, and cinnamon. Dip bread slices into the mixture to soak.
Remove Dutch oven from heat. Melt butter in the pot, then blend in brown sugar until combined.
Once the mixture becomes light brown, place peaches on the bottom of the Dutch oven. Arrange soaked bread slices upright on top of the peaches.
Bake using 14 coals on top and 7 on bottom for 35–45 minutes, checking occasionally to ensure the edges do not burn.
✨ Notes
- For extra sweetness, add 2 tbsp brown sugar to the custard.
- Use fresh or frozen peaches if preferred; adjust cooking time as needed.
- To avoid burning, rotate the Dutch oven every 10 minutes.
- Best served warm straight from the pot.
