Making 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 mixing bowl, whisk together the flour, baking powder, baking soda, salt, and sugar until well combined.
3. Combine Wet Ingredients: In another bowl, whisk the buttermilk, eggs, melted butter, and vanilla extract until smooth.
4. Combine Mixtures: Pour the wet ingredients into the dry ingredients, stirring gently until just combined. Be careful not to overmix.
5. Add Blueberries: Fold in the blueberries gently to distribute them throughout the batter.
6. Bake: Pour the batter into the prepared baking dish and spread it evenly. Bake in the preheated oven for 30-35 minutes or until golden brown and a toothpick inserted in the center comes out clean.
7. Cool: Remove from the oven and let it cool for about 5-10 minutes before slicing.
8. Serve: Cut into squares and serve warm with maple syrup, if desired.

These straightforward steps make it easy for anyone to create this delightful casserole. The process is quick, and the result is a beautifully baked dish that everyone will enjoy.
