Ingredients
  

For the Pancake Casserole

  • 2 cups all-purpose flour
  • 2 tablespoons sugar or coconut sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 2 cups milk dairy or almond milk
  • 2 large eggs
  • 2 tablespoons melted butter or coconut oil
  • 1 teaspoon vanilla extract
  • 1 ½ cups blueberries fresh or frozen

Optional Topping

  • 2 tablespoons melted butter
  • 2 tablespoons brown sugar
  • ¼ cup sliced almonds or chopped pecans
  • Maple syrup or powdered sugar for serving

Instructions  

1. Mix the Dry Ingredients

  • In a large bowl, whisk together flour, sugar, baking powder, and salt.

2. Mix the Wet Ingredients

  • In another bowl, whisk milk, eggs, melted butter, and vanilla until smooth.

3. Combine Batter

  • Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix—small lumps are fine.

4. Add Blueberries

  • Gently fold in the blueberries. If using frozen berries, do not thaw to prevent bleeding.

5. Pour into Baking Dish

  • Grease a 9×13-inch baking dish and pour the batter evenly into the dish.

6. Cover and Refrigerate Overnight

  • Cover tightly with foil or plastic wrap and refrigerate for at least 6 hours or overnight.

7. Bake in the Morning

  • Preheat oven to 350°F (175°C). Bake uncovered for 35–45 minutes, until golden and set in the center.

8. Add Optional Topping

  • Brush melted butter over the top, sprinkle with brown sugar and nuts, and broil for 2–3 minutes for a caramelized finish.

9. Serve

  • Let cool slightly, slice into squares, and serve with maple syrup, powdered sugar, or whipped cream.
