Making your Blueberry Buttermilk Pancake Casserole is simple. Just follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, mix the buttermilk, eggs, melted butter, and vanilla extract until fully combined.
4. Combine Mixtures: Gradually pour the wet ingredients into the dry ingredients, stirring gently until just combined. Be careful not to overmix.
5. Add Blueberries: Gently fold in the blueberries, ensuring they are evenly distributed throughout the batter.
6. Pour into Baking Dish: Transfer the batter to the prepared baking dish, spreading it evenly.
7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the casserole is golden brown and a toothpick comes out clean.
8. Cool: Once baked, remove the casserole from the oven and let it cool for about 5 minutes before cutting.
9. Serve: Cut into squares, serve warm, and drizzle with maple syrup, if desired.

With these straightforward instructions, you’ll have a beautiful Blueberry Buttermilk Pancake Casserole ready to impress.
