Preheat oven to 350°F (175°C). Place the butter in a 9×9-inch baking dish and let it melt completely by placing the dish in the oven for 3-4 minutes.
02 -
In a large bowl, whisk together flour, baking powder, salt, and sugar. Add buttermilk, vanilla extract, and lemon extract if using. Stir until the batter is smooth.
03 -
Carefully pour the batter evenly over the melted butter in the baking dish without stirring. Let the butter sit on top of the batter.
04 -
Distribute the lemon pie filling or lemon curd evenly over the batter. The filling will sink during baking, creating a custard-like layer at the bottom.

Bake in the oven for 45-55 minutes until puffed up and golden brown around the edges. The center should be set but slightly soft. A toothpick inserted should come out clean with a few moist crumbs.

Remove the cobbler from the oven and let it cool for 10-15 minutes. This helps the filling firm up, making it easier to serve.

Cut the cobbler into squares and serve warm. Top with whipped cream, ice cream, powdered sugar, or fresh lemon slices if desired.
