Follow these simple steps to create your very own Blueberry Buttermilk Pancake Casserole:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt until well mixed.
3. Mix Wet Ingredients: In another bowl, combine the buttermilk, sugar, eggs, melted butter, and vanilla extract. Whisk until fully incorporated.
4. Combine Mixtures: Slowly pour the wet ingredients into the dry ingredients, stirring gently until just combined. Avoid overmixing to keep the pancakes light and fluffy.
5. Fold in Blueberries: Gently fold in the blueberries, ensuring they’re evenly distributed throughout the batter.
6. Pour into Baking Dish: Transfer the batter into the prepared baking dish, smoothing the top with a spatula.
7. Bake: Place the baking dish in the preheated oven and bake for 35-40 minutes or until the casserole is set and lightly golden on top.
8. Cool Slightly: Once baked, remove the casserole from the oven and allow it to cool for about 5-10 minutes before serving.
9. Optional Toppings: Before serving, you may dust the top with powdered sugar or drizzle with maple syrup, if desired.
