Making Blueberry Buttermilk Pancake Casserole is easier than you might think. Just follow these steps for a delicious outcome:

1. Preheat the oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with non-stick spray or butter.
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, whisk the buttermilk, eggs, melted butter, and vanilla extract until smooth.
4. Mix Together: Pour the wet ingredients into the dry ingredients. Stir gently until just combined. Be careful not to overmix; small lumps are okay.
5. Add Blueberries: Gently fold in the fresh blueberries into the batter.
6. Pour into Baking Dish: Pour the batter into the prepared baking dish, spreading it evenly.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown, and a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for about 10 minutes before serving.
9. Slice and Serve: Cut into squares, drizzle with maple syrup, and enjoy!

These simple steps will guide you in creating this incredible casserole with ease.
