Preheat Oven:
Preheat your oven to 350°F (175°C).
Pour melted butter into the bottom of a 9x9-inch baking dish or similar size.
Make the Batter:
In a medium bowl, whisk together flour, sugar, lemon zest, baking powder, and salt.
Stir in milk and vanilla until a smooth batter forms.
Assemble the Cobbler (No Stirring!):
Carefully pour the batter over the melted butter in the baking dish. Do not stir.
Spoon the lemon pie filling evenly over the batter. Again, do not stir—the magic happens as it bakes!
Bake:
Bake for 45–50 minutes, or until the top is golden brown and the center is set.
Cool & Serve:
Let cool for 10–15 minutes before serving.
Dust with powdered sugar or top with whipped cream, if desired.
