Impossiable Pie

This was a fun pie recipe my family found years ago, but lost and have never been able to find it. I ran into in online by accident while looking for a different recipe. I wanted to share it with them, and any of you out there wanting to try. It is the easiest pie you will ever make. You put all the ingredients in the blender, mix, put in pie pan, cook. It is really that simple. While it is cooking it seperates into layers. Its crazy, but true.

Ingredients
Cooking spray
1 1/3 cups sugar
1 cup buttermilk
1/2 cup biscuit mix (bisquick)
1/3 cup unsalted butter, melted
1 teaspoon vanilla extract
3 large eggs
Confectioners' sugar (optional)
Directions
Preheat the oven to 350 degrees F. Coat a 9-inch pie plate with cooking spray.
Combine the sugar, buttermilk, biscuit mix, melted butter, vanilla, and eggs in a blender and process until smooth. Pour into prepared pie plate and bake until browned and still a little jiggly (the pie will set as it cools), 30 to 40 minutes.
Let cool for 10 minutes before slicing into wedges. If desired, sift confectioners' sugar or cocoa (or a combo) over the wedges before serving.
I hope you all enjoy!
