Ingredients
Method
Preheat and Prep Your Pan
- Preheat your oven to 350°F (175°C). Pour the melted butter directly into a 9x13-inch baking dish and tilt it gently so the butter coats the entire bottom. Do not skip this step or wipe it out. The pan should look glossy and richly coated.
Toss the Blueberries
- In a medium bowl, combine the blueberries with ¼ cup of the sugar, the lemon juice, and lemon zest. Stir gently so you do not crush the berries. Set this aside while you make the batter.
Make the Batter
- In a separate bowl, whisk together the flour, remaining ½ cup of sugar, baking powder, and salt. Add the milk and vanilla extract and stir until just combined. A few small lumps are perfectly fine. Do not overmix.
Layer It Up
- Pour the batter evenly over the melted butter in the baking dish. Do not stir. Next, spoon the blueberry mixture evenly over the top of the batter. Again, resist the urge to stir. Everything will find its place in the oven.
Bake Until Golden and Bubbling
- Slide the dish into the center of your preheated oven and bake for 40 to 45 minutes. Look for a deep golden-brown crust on top with the blueberry filling bubbling up around the edges and through the crust. A toothpick inserted into the batter portion should come out clean.
- Let the cobbler rest for 10 minutes before serving so the filling can set up slightly. Serve warm topped with vanilla ice cream, whipped cream, or a drizzle of cold heavy cream.
Notes
Substitution Tips: Swap whole milk for oat milk or almond milk for a dairy-free batter. Use a gluten-free 1:1 baking flour if needed. Brown sugar in place of granulated sugar adds a lovely caramel depth. You can mix the dry ingredients the night before and store them in a zip-lock bag on the counter. Do not stir the layers once assembled in the pan. Make sure butter is fully melted and warm. Bake until genuinely golden, not pale. Let the cobbler rest 10 minutes before serving so the filling sets. Store leftovers covered in the refrigerator for up to four days. To freeze, wrap individual portions in plastic wrap and store in a freezer-safe bag for up to two months. Reheat in a 325°F oven for 15 minutes to bring back the crispy top. If using frozen blueberries, no need to thaw — just add 2 to 3 extra minutes of baking time.
