Prep the Bread:
Cut brioche or challah into 1-inch cubes. Set aside to let them dry out slightly, which helps them soak up the batter without falling apart.

Make the Batter:
In a medium bowl, whisk together the eggs, milk, vanilla, cinnamon, sugar, and a pinch of salt until fully combined.

Dip the Bread:
Working in batches, gently toss the bread cubes in the batter to coat. Let excess drip off—don’t soak them too long.

Heat and Fry:
Heat a large non-stick skillet or griddle over medium heat. Add 1 tbsp of butter and swirl to coat. Add a batch of coated bread cubes in a single layer. Cook 2–3 minutes per side, turning occasionally, until all sides are golden and crispy.

Repeat:
Remove finished bites and place on a paper towel–lined plate or a baking sheet kept warm in a 200°F oven. Repeat the frying process with the remaining bread, adding more butter as needed.

Serve:
Pile the warm bites on a platter, dust with powdered sugar, and serve with maple syrup, whipped cream, or fresh fruit on the side.
