Incorporate Dry Ingredients: Add almond flour, baking powder, and protein powder (if using). Mix gently until combined.

Adjust Texture: If batter seems too thick, stir in milk 1 tablespoon at a time.

Fold in Blueberries: Gently fold in blueberries to avoid breaking them.

Transfer to Dish: Pour mixture into prepared baking dish and smooth the top evenly.

Top with Almonds: Sprinkle sliced almonds over the surface for crunch.

Bake: Bake for 35–40 minutes, or until center is set and lightly golden.

Cool & Serve: Let cool 10–15 minutes before slicing. Serve warm or chilled.

Let casserole rest before cutting for clean slices.

Store leftovers in airtight container in refrigerator.

Reheat gently to prevent drying out.

Add a dollop of Greek yogurt before serving for extra protein.
