Lightly grease a 9x13 inch pan with butter

Place the torn bread pieces into the pan and set aside

In a medium size bowl, whisk the 8 eggs together

To the eggs, mix in the sugar, milk, half & half, heavy cream, 1 teaspoon cinnamon, 1/2 teaspoon nutmeg, and 1/2 teaspoon salt. Whisk until well combined.

Pour the milk-egg mixture over the bread pieces

Cover with plastic wrap and place in the refrigerator for 8 hours or overnight

To make the streusel topping, add the butter, flour, brown sugar, and remaining spices to a food processor

Pulse 5-6 times until crumbly

Add in the nuts and pulse once or twice more until combined

Cover the streusel mixture and refrigerate until ready to bake

When ready to bake, pre-heat the oven to 350*
