Ingredients

Batter Ingredients

1 1/2 loaves baguette bread
15 large eggs
2 3/4 cups milk
1/2 cups buttermilk
3/4 cups heavy cream
1 tbsp espresso powder (optional – but it’s a nice kick!)
2 tbsp pure vanilla
3/4 cup turbinado sugar
1 tbsp cinnamon

Topping

8 tbsp cold unsalted butter (blender optional – we cube the cold butter and mix with our hands)
2 1/4 cups turbinado sugar
1 cup flour
1/4 tsp sea salt

Instructions

Cut bread into cubes and spread evenly into a greased 9 x 13″ pan and 8 x 8″ pan. It’s important not to overload the bread in layers or the egg mixture will not be enough.
In a bowl, whisk together eggs, buttermilk, milk, cream, espresso powder, turbinado sugar, and cinnamon.
Pour the egg mixture over the baguette bread, covering the top slightly. Cover and refrigerate overnight, at least 7 hours.
Combine the butter, sugar, flour and sea salt. Mix with your hands until crumbly. Put in a ziplock bag and store in the refrigerator until the morning.
In the morning, set the oven to 350 degrees. Take out the casserole and top evenly with the crumb topping.
Bake for 40-50 minutes until all egg is cooked and it’s as crunchy as you like it.
