Ingredients
Method
Preheat Oven:
- Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish.
Mix Dry Ingredients:
- In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
Mix Wet Ingredients:
- In another bowl, whisk together buttermilk, eggs, melted butter, and vanilla extract.
Combine:
- Pour wet ingredients into dry ingredients and stir until just combined. Gently fold in blueberries.
Bake:
- Pour batter into prepared baking dish. Bake for 35–40 minutes, until a toothpick inserted in the center comes out clean and the top is lightly golden.
Serve:
- Sprinkle with powdered sugar or drizzle with maple syrup before serving.
Notes
Use frozen blueberries directly in the batter — no need to thaw; just toss in a little flour to prevent them from sinking.
Let the casserole rest 5 minutes before slicing for cleaner pieces.
For extra flavor, add a pinch of cinnamon or lemon zest to the batter.
Can be made ahead and reheated in the oven or microwave for an easy breakfast.
