Creating Blueberry Buttermilk Pancake Casserole is simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, sugar, and salt until well combined.
3. Combine Wet Ingredients: In another bowl, whisk the buttermilk, eggs, melted butter, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet mixture to the dry ingredients, stirring until just combined. Do not overmix; a few lumps are okay.
5. Fold in Blueberries: Gently fold in the blueberries, making sure they are evenly distributed throughout the batter.
6. Pour into Baking Dish: Pour the batter into the prepared baking dish, spreading it out evenly.
7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
8. Cool: Remove the casserole from the oven and allow it to cool for about 10 minutes before serving.
9. Cut and Serve: Slice the casserole into squares and serve warm with maple syrup drizzled on top, if desired.
