Ingredients
Method
- Prep the Oven & Pan: Preheat your oven to 175°C (350°F). Place the butter cubes in your 20x20 cm baking dish (or a 10-inch cast-iron skillet). Pop it into the oven for 2–3 minutes until the butter is completely melted and just starting to bubble.
- Prepare the Berries: Carefully remove the hot pan from the oven. Add the blueberries, sugar, lemon zest, and the cornstarch slurry directly into the melted butter.
- Pro Tip: If using fresh berries, gently mash a few of them with a fork to release their juices. Stir everything together right in the pan.
- Mix the Batter: In a separate medium bowl, whisk together the flour, sugar, baking powder, and cinnamon. Pour in the milk and whisk until you have a smooth, consistent batter.
- Assemble: Pour the batter evenly over the berry mixture. Important: Do not stir! The batter will naturally rise to the top and create those beautiful "cobblestones" during baking.
- Bake: Place in the oven for approximately 40 minutes, or until the top is a deep golden brown and the edges are crispy.

Notes
The "Doneness" Hack: Before taking it out, use a spoon to slightly "break" the crust in one spot to ensure the batter is fully cooked on the underside (where it touches the fruit). If it looks too wet, give it another 5 minutes.
