Ingredients
Scale
- 1 loaf of brioche bread, cut into cubes
- 6 large eggs
- 2 cups whole milk
- 1 cup heavy cream
- 1/2 cup granulated sugar
- 1 tablespoon vanilla powder
- 1 teaspoon ground cinnamon
- 1/2 cup rainbow sprinkles (for topping)
Instructions
- Step 1: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla bean paste, and ground cinnamon until well combined.
- Step 2: Place the cubed brioche bread into a greased 9×13 inch baking dish and pour the egg mixture over the bread. Gently toss to ensure all the bread is soaked in the mixture.
- Step 3: Cover the baking dish with plastic wrap or aluminum foil and refrigerate for at least 4 hours or overnight to allow the flavors to meld and the bread to fully absorb the liquid.
- Step 4: Preheat your oven to 350°F (175°C). Once preheated, remove the cover from the baking dish and sprinkle rainbow sprinkles evenly over the top of the casserole.
- Step 5: Bake in the preheated oven for about 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean. Let cool slightly before serving. Enjoy your festive birthday cake French toast casserole!
Notes
- For optimal storage, cover any leftovers tightly with plastic wrap or transfer them to an airtight container and refrigerate for up to 3 days.
- To reheat, simply warm individual portions in the microwave for about 30-60 seconds or pop the whole casserole back in a preheated oven at 350°F (175°C) for about 15 minutes until heated through.
- Serve your Overnight Birthday Cake French Toast Casserole with a drizzle of maple syrup and a dollop of whipped cream for an extra special touch that complements the sweetness of the sprinkles.
- For best results, let the casserole sit overnight in the fridge to allow the brioche to fully absorb the egg mixture, ensuring every bite is rich and flavorful.
