Why You’ll Love Easy Overnight Blueberry Pancake Casserole Recipe

This recipe is a great choice when you want a warm, comforting breakfast that feels special but is surprisingly easy to prepare. Since the batter is assembled the night before, all the hard work is already done by morning. Just let the dish sit briefly at room temperature, add the streusel if you like, and bake.

You’ll also love how family-friendly and versatile it is. The blueberries add sweetness and freshness, while the maple syrup and vanilla give the casserole classic pancake flavor. It is ideal for serving a group, and each square comes out soft, tender, and ready to enjoy with extra syrup or a dusting of powdered sugar.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
2 tablespoons granulated sugar
2 large eggs
1 3/4 cups milk
1/4 cup pure maple syrup
1/4 cup unsalted butter, melted
1 teaspoon vanilla extract
1 1/2 cups fresh or frozen blueberries

For the optional streusel topping:

2 tablespoons unsalted butter, melted
1/4 cup brown sugar
1/4 cup all-purpose flour
1/2 teaspoon ground cinnamon

Directions

Grease a 9×13-inch baking dish with butter or nonstick spray.

In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and sugar until evenly combined.

In a separate bowl, whisk together the eggs, milk, maple syrup, melted butter, and vanilla extract until smooth.

Pour the wet ingredients into the dry ingredients and stir gently until just combined. Do not overmix. A few lumps in the batter are perfectly fine.

Fold in the blueberries carefully. If you are using frozen blueberries, add them directly from the freezer so they do not bleed too much into the batter.

Pour the batter evenly into the prepared baking dish and smooth the top if needed.

Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 to 8 hours or overnight.

When ready to bake, remove the dish from the refrigerator and let it sit at room temperature for 20 to 30 minutes. Preheat the oven to 350°F (175°C).

If using the streusel topping, stir together the melted butter, brown sugar, flour, and cinnamon in a small bowl until crumbly. Sprinkle it evenly over the casserole.

Bake for 35 to 45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.

Let the casserole cool for about 10 minutes before slicing and serving. Serve warm with maple syrup or powdered sugar if desired.

Variations

There are plenty of easy ways to make this pancake casserole your own. Swap the blueberries for raspberries, chopped strawberries, or a mix of berries for a different fruit flavor. You can also add lemon zest to the batter for a brighter, fresher taste that pairs especially well with blueberries.

For extra texture, sprinkle chopped pecans or walnuts over the streusel before baking. If you want a richer finish, serve each portion with whipped cream or a spoonful of vanilla yogurt. You can also use chocolate chips in place of some of the berries for a sweeter, dessert-like version.

Storage/Reheating

Store any leftovers covered in the refrigerator for up to 4 days. For best results, let the casserole cool completely before storing so excess moisture does not build up.

To reheat, warm individual portions in the microwave for about 30 to 60 seconds, depending on the size of the slice. You can also reheat larger portions in a 300°F oven until warmed through. If you want to preserve the texture of the topping, the oven is the better choice.

This casserole can also be frozen. Wrap individual portions or the whole baked casserole tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work very well in this recipe. Add them straight from the freezer so they hold their shape better and do not color the batter too much.

Do I have to refrigerate it overnight?

The overnight chill is recommended because it allows the batter to rest and makes this recipe especially convenient for the next morning. A minimum of 6 to 8 hours works best.

Can I make this without the streusel topping?

Yes, the streusel is optional. The casserole is still delicious without it and will have more of a classic baked pancake texture.

What type of milk works best?

Regular whole milk or 2% milk both work well. You can also use a non-dairy milk if needed, though the texture may vary slightly.

How do I know when the casserole is done?

The top should be golden brown, and a toothpick inserted into the center should come out clean or with just a few moist crumbs.

Can I prepare it more than one night in advance?

It is best prepared the night before, but you can assemble it earlier in the day if you plan to bake it the following morning. For the freshest texture, avoid letting it sit too long before baking.

Can I add other mix-ins?

Yes, you can add ingredients like lemon zest, chopped nuts, or chocolate chips. Just avoid overloading the batter so it still bakes evenly.

Why should I not overmix the batter?

Overmixing can make the casserole dense and tough. Stir just until the ingredients are combined to keep the texture soft and fluffy.

Can I serve this for brunch or holidays?

Absolutely. This recipe is ideal for brunch tables, holiday mornings, and special family breakfasts because it feeds several people and is easy to bake all at once.

What should I serve with blueberry pancake casserole?

It pairs well with maple syrup, powdered sugar, fresh fruit, yogurt, breakfast sausage, or crispy bacon for a more complete meal.
