This recipe transforms classic French toast into individual, portable muffins with a wonderfully crunchy, sweet exterior and a soft, custardy interior. The key is starting with day-old bread—challah, brioche, or even sourdough work beautifully because slightly stale bread soaks up the custard without turning mushy. You will need about four cups of cubed bread, and you can cut the cubes into roughly half-inch to one-inch pieces so they fit neatly into the muffin cups.
Begin by preheating your oven to 350 degrees Fahrenheit and generously greasing a twelve-cup muffin tin with butter or non-stick spray, or line it with paper liners for easier cleanup. In a large mixing bowl, whisk together three or four large eggs with one cup of milk—whole milk gives the richest texture, but almond milk works perfectly well too. Add a quarter cup of granulated sugar, one teaspoon of vanilla extract, one teaspoon of ground cinnamon, and a pinch each of nutmeg and salt if you like that classic French toast warmth. Whisk everything until the custard is completely smooth and the sugar has dissolved.
Now add your cubed bread to the bowl and gently fold and toss it with a spatula or your hands until every single piece is thoroughly coated in the custard mixture. Let the mixture rest for about ten to fifteen minutes right there in the bowl, stirring once or twice, so the bread has time to absorb all that liquid goodness. This resting period is what gives you that perfect French toast texture—soft and eggy in the center, not dry or bready.
Once the bread has soaked, divide the mixture evenly among the twelve muffin cups, pressing each portion down lightly with the back of a spoon so the cubes pack together snugly and hold their shape during baking. Slide the pan into the oven and bake for twenty-five to thirty minutes, until the muffins are puffed up, golden brown on top, and a toothpick inserted into the center comes out clean or with just a few moist crumbs. You will know they are ready when the kitchen fills with that warm, sweet cinnamon aroma.
While the muffins are still warm from the oven, prepare the cinnamon-sugar coating. In a small bowl, stir together half a cup of granulated sugar with two teaspoons of ground cinnamon. In another small bowl, melt four tablespoons of unsalted butter. Take each warm muffin and brush the top generously with the melted butter, then immediately dip the buttered top into the cinnamon-sugar mixture, turning it gently to coat evenly. The butter helps the sugar cling and creates that irresistible crunchy crust that makes these muffins so special.
Serve the muffins warm, right after coating, when the sugar is still slightly crackly and the centers are soft and custardy. They are wonderful on their own, but you can also offer maple syrup, honey, or a dusting of powdered sugar on the side for extra indulgence.
These muffins are wonderfully versatile. If you want to get creative, fold in half a cup of chocolate chips, fresh blueberries, or chopped pecans along with the bread and custard before baking for an extra layer of flavor and texture. You can also assemble the entire dish the night before: fill the muffin tin, cover it tightly with plastic wrap, and refrigerate overnight; in the morning, simply pop the pan straight into the oven, adding about five extra minutes to the baking time since the mixture will be cold.
Leftovers keep well in an airtight container in the refrigerator for up to three days. To bring back that freshly baked texture, reheat them in a toaster oven or regular oven at 350 degrees for five to seven minutes rather than using the microwave, which can make them soggy. For longer storage, you can freeze the baked, uncoated muffins in a freezer bag for up to a month; when you are ready to enjoy them, thaw overnight in the fridge, then brush with butter and roll in cinnamon sugar right before reheating and serving.
Whether you are making these for a lazy weekend breakfast, a holiday brunch, or a grab-and-go weekday treat, these Cinnamon Sugar French Toast Muffins deliver all the cozy comfort of classic French toast in a fun, handheld form that everyone will love.
