Instructions
1. Preheat oven to 350°F. Place butter in a 9×9 inch baking dish and melt in preheated oven for 3-4 minutes until fully melted. Remove from oven.
2. In a bowl, whisk together the flour, baking powder, salt, and sugar.
3. Whisk in the buttermilk, vanilla, and lemon extract (if using) until a smooth batter forms.
4. Pour the batter evenly over the melted butter in the baking dish (do not stir).
5. Spoon the lemon pie filling or lemon curd evenly over the batter.
6. Bake for 45-55 minutes until puffed and golden brown around the edges.
7. Remove from oven and let cool slightly. The lemon filling will be a pudding on the bottom!
8. Serve warm, topped with whipped cream, ice cream, lemon slices, powdered sugar, or desired toppings.
