Blueberry Buttermilk Pancake Casserole
Blueberry buttermilk pancake casserole is a simple, comforting bake that tastes like a skillet pancake stretched across an entire 9×13 pan. I first made this when I wanted the flavor of fluffy blueberry pancakes without standing over a hot griddle—perfect for weekend brunches, school mornings, or when you need an easy dish to feed a crowd. If you enjoy baked breakfast casseroles, you’ll also like the texture and ease of this baked French-toast-style option like a quick blueberry French toast casserole that delivers similar weekend-brunch vibes.
Why you’ll love this dish
This casserole turns pancake batter into an effortless one-pan bake. It’s:
- Fast to mix and hands-off while it bakes.
- Great for serving a group—no flipping individual pancakes.
- Kid-friendly and easy to customize.
"We served this at a family brunch and everyone loved how it tasted like pancakes without the waiting." — a happy taste-tester
It’s also forgiving: swap berries, add lemon zest, or make it ahead. For a protein-forward breakfast that borrows the same baked pancake idea, consider baked protein pancake bowls for mornings when you want to press pause on sugar and boost protein.
How this recipe comes together
The method is straightforward and friendly to cooks of any level. First you mix dry ingredients, whisk wet ingredients separately, then fold them together without overmixing. Fresh blueberries get folded in and the batter is poured into a greased 9×13 pan. In the oven the batter puffs and sets, producing a tender interior and a lightly golden top. The baking step converts pancake batter into a sliceable casserole—think of it as sheet-pan pancakes that you can cut into squares.

What you’ll need
- 2 cups all-purpose flour
- 1/4 cup granulated sugar
- 1 tablespoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine salt
- 2 cups buttermilk (see substitutions below)
- 4 large eggs
- 1/2 cup melted butter (plus a little for greasing)
- 2 cups fresh blueberries (or frozen, see notes)
- 1 teaspoon vanilla extract
Notes and substitutions:
- Buttermilk: If you don’t have it, make a quick substitute by adding 2 tablespoons lemon juice or white vinegar to a 2-cup measuring cup, then fill to 2 cups with milk and let sit 5 minutes.
- Blueberries: Frozen berries work fine—no need to thaw. Toss frozen berries lightly in a tablespoon of flour to reduce bleeding.
- Butter: Use melted and slightly cooled. For dairy-free, substitute melted coconut oil but expect a subtle flavor change.

Directions to follow
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
- In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly combined.
- In a separate bowl, whisk the buttermilk, eggs, melted butter, and vanilla until smooth.
- Pour the wet mixture into the dry ingredients. Stir gently until just combined—stop when you no longer see dry streaks. A few lumps are okay.
- Fold in the blueberries gently, taking care not to crush them.
- Pour the batter into the prepared baking dish and smooth the top with a spatula.
- Bake for 30–35 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
- Let the casserole rest for 5–10 minutes before slicing into squares. Serve warm.
How to plate and pair
Serve warm squares on a platter for easy family-style brunch. Top individual pieces with:
- A dusting of powdered sugar and a drizzle of maple syrup.
- A spoonful of whipped cream or Greek yogurt and extra berries.
- A lemon curd smear for bright contrast.
Pair the casserole with crispy bacon or sausage for savory balance. If you want a portable option to serve alongside, try bakery-style blueberry muffins to give guests a handheld choice.
How to store & freeze
- Refrigerate: Cool completely, cover tightly with foil or an airtight container, and refrigerate up to 3–4 days.
- Reheat: Microwave single portions for 20–40 seconds or rewarm in a 350°F oven for 8–10 minutes until heated through.
- Freeze: Wrap individual squares in plastic wrap and place in a freezer bag. Freeze up to 2 months. Thaw overnight in the refrigerator or reheat from frozen in a low oven.
Always cool the casserole to room temperature before sealing to avoid condensation and sogginess.
Tricks for success
- Don’t overmix: Overworking the batter develops gluten and makes the casserole dense. Mix until mostly combined.
- Use room-temperature eggs: They incorporate better and help a lighter texture.
- Distribute berries: Toss berries with a teaspoon of flour so they stay suspended in the batter.
- Test doneness: A toothpick in the center should come out clean or with a few moist crumbs—not wet batter.
- Browning: If the top is browning too quickly, tent with foil for the last 10 minutes.
Creative twists
- Lemon-blueberry: Add 1 tablespoon lemon zest to the batter for a bright lift.
- Streusel topping: Mix 1/2 cup flour, 1/4 cup brown sugar, and 3 tablespoons cold butter; crumble over the top before baking.
- Apple-cinnamon swap: Replace blueberries with chopped apples and add 1 teaspoon cinnamon.
- Vegan: Use a plant-based buttermilk (soy or oat milk + acid), 4 flax eggs (4 tbsp ground flax + 12 tbsp water), and coconut oil for butter.
Common questions
Q: Can I use frozen blueberries instead of fresh?
A: Yes. You don’t need to thaw them; toss frozen berries with a tablespoon of flour and fold in gently so they don’t sink or bleed excessively.
Q: Can this be made ahead for a brunch?
A: Make it the night before and refrigerate covered. Rewarm in a 350°F oven for 15–20 minutes before serving. For best texture, bake fresh if possible.
Q: How do I make a dairy-free version?
A: Use plant-based milk plus 2 tablespoons vinegar to mimic buttermilk, replace butter with melted coconut or vegan butter, and use flax eggs if you need an egg-free option.
Q: Why is the baking soda in the recipe?
A: Baking soda reacts with the acidity of buttermilk to give lift and a light crumb. The small amount keeps texture tender without soapy off-flavors.
Q: What’s the best way to reheat leftovers without drying them out?
A: Reheat covered in a 325–350°F oven for 8–12 minutes or microwave briefly with a damp paper towel over the slice to retain moisture.
