Make the streusel first: combine the flour, brown sugar, cinnamon, and salt in a bowl. Then cut in the butter (I usually just use my fingers for this part) and mix/press into the dry ingredients until it’s crumbly. Cover and place in the fridge.
¼ cup all-purpose flour, ¼ cup light brown sugar, packed, ¼ tsp. ground cinnamon, pinch salt, ¼ cup unsalted butter
In a large bowl, whisk together the eggs, milk, vanilla, cinnamon, salt, and sugar.
8 large eggs, 2 ½ cups whole milk, 1 tbsp. vanilla, ¾ tsp. ground cinnamon, ½ tsp. salt, ½ cup granulated sugar
Grease a 9x13 pan with baking spray. Tear the French bread into pieces and place in the prepared 9x13 pan. Pour this over the French bread. Pour evenly so no bread pieces are left dry.
1 loaf French bread
Add the diced strawberries and blueberries over the top.
1 cup strawberries, 1 cup blueberries
Cover tightly and refrigerate for 4 hours or overnight.
Preheat the oven to 350°F.
Sprinkle the streusel all over the top.
Bake for 45-55 minutes, or until set. Allow to rest for 10-15 minutes before serving. Enjoy with more fresh berries, powdered sugar, or maple syrup.
