Step 1

Preheat oven to 350°F. Place butter in a 9x9 inch baking dish and melt in preheated oven for 3-4 minutes until fully melted. Remove from oven.

Step 2

In a bowl, whisk together the flour, baking powder, salt, and sugar.

Step 3

Whisk in the buttermilk, vanilla, and lemon extract (if using) until a smooth batter forms.

Step 4

Pour the batter evenly over the melted butter in the baking dish (do not stir).

Step 5

Spoon the lemon pie filling or lemon curd evenly over the batter.

Step 6

Bake for 45-55 minutes until puffed and golden brown around the edges.

Step 7

Remove from oven and let cool slightly. The lemon filling will be a pudding on the bottom!

Step 8

Serve warm, topped with whipped cream, ice cream, lemon slices, powdered sugar, or desired toppings.
