Preheat the oven to 350 F.
Place diced butter into an 8 1/2 x 11 baking dish or deep dish pie plate.
Put the dish into the oven and let butter melt.
In a separate bowl, combine the flour, sugar, buttermilk, and extracts. Stir to make a batter.
When butter is melted, carefully remove the pan from the oven.
Pour the batter over the melted butter. Do not stir. (I know you will want to, LOL)
Using a spoon, scoop lemon pie filling over the batter and butter mixture in dollops.
Return the dish to the oven.
Bake for 45-55 minutes or until the crust is a golden brown.
Remove and let cool for a few minutes.
Serve with ice cream or whipped cream.
