Instructions
Prepare the Baking Dish
- Grease a 9x13-inch baking dish with butter or nonstick spray.
Mix the Dry Ingredients
- In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
Mix the Wet Ingredients
- In a separate bowl, whisk together the eggs, milk, maple syrup, melted butter, and vanilla extract until smooth.
Combine Wet and Dry Ingredients
- Pour the wet ingredients into the dry ingredients. Stir gently until just combined. Do not overmix; a few lumps are fine.
Add the Blueberries

Assemble the Casserole

Cover and Refrigerate
- Cover tightly with plastic wrap or foil and refrigerate for at least 6–8 hours or overnight.
Prepare for Baking
- Remove the casserole from the refrigerator and let it sit at room temperature for 20–30 minutes. Preheat oven to 350°F (175°C).
Add Optional Streusel (If Using)
- In a small bowl, mix melted butter, brown sugar, flour, and cinnamon until crumbly. Sprinkle evenly over the top.
Bake
- Bake for 35–45 minutes, or until golden brown and a toothpick inserted in the center comes out clean.
Cool and Serve
- Let cool for 10 minutes before slicing. Serve warm with maple syrup or powdered sugar.
