Let’s Make it Together
Prepare Your Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or nonstick spray to ensure easy serving later.
Slice the Bread: Cut your bread into cubes or slices depending on your preference. Aim for about 1-inch pieces for even soaking and cooking.
Make the Custard Mixture: In a large bowl, whisk together eggs, milk, cinnamon, vanilla extract, and maple syrup until fully combined. The mixture should be creamy and fragrant.
Add Bread to Custard: Gently fold your bread pieces into the custard mixture until they are fully coated. Allow them to soak for at least 15 minutes—this step is crucial for soft centers!
Bake the Casserole: Pour everything into your prepared baking dish and spread evenly. Bake in your preheated oven for about 40-45 minutes until golden brown on top and set in the middle.
Serve and Enjoy!: Remove from oven and let cool slightly before dusting with powdered sugar. Serve warm with fresh fruit or additional maple syrup.
With each step, you’ll be enveloped by delightful aromas that will have everyone eagerly anticipating the first bite!
