Step 1 – Prepare the Bread: If your bread is fresh, preheat your oven to 300°F (150°C). Spread the bread cubes in a single layer on a baking sheet and bake for 10–15 minutes until firm and slightly dry. Remove and let cool completely.
Step 2 – Make the Custard: In a large mixing bowl, whisk together the eggs, milk or heavy cream, granulated sugar, vanilla extract, nutmeg, and salt. Whisk until fully combined and smooth.
Step 3 – Combine Bread and Custard: Add the dried bread cubes to the custard mixture. Using a rubber spatula, gently fold until every piece is well coated. Allow the bread to soak for at least 10 minutes, or cover and refrigerate overnight for deeper flavor.
Step 4 – Prepare the Cinnamon Sugar Coating: In a small bowl, mix together the granulated sugar and ground cinnamon. Set aside.
Step 5 – Prep the Muffin Tin: Preheat your oven to 350°F (175°C). Brush each cup of a 12-cup muffin tin generously with melted butter. Sprinkle a small amount of the cinnamon sugar mixture into each cup to coat the bottom.
Step 6 – Fill the Muffin Cups: Using an ice cream scoop, evenly portion the soaked bread mixture into each muffin cup, filling them about three-quarters full. Sprinkle the remaining cinnamon sugar generously over the top of each muffin.
Step 7 – Bake: Place the muffin tin in the center rack of your preheated oven and bake for 22–25 minutes, or until the tops are golden brown and the edges pull away from the pan. If the tops brown too quickly, loosely tent with aluminum foil.
Step 8 – Cool and Serve: Remove from the oven and allow the muffins to cool in the tin for 5 minutes before transferring to a wire rack. Serve warm with maple syrup, fresh berries, or whipped cream.
