This pie is truly miraculous—simply mix all the ingredients together, pour into a pan and bake, and it forms its own topping and crust around a creamy coconut filling. This recipe was shared by Walt Hanson, who said, “The Impossible Pie is a coveted recipe from my Grandma. She used to make this for me on my birthday growing up. I love recreating those memories and attempting to bake it—it will never quite be the same, but I try!”
Preheat oven to 350°F. Add all ingredients to a blender and mix on high until smooth (or mix by hand in a large bowl). Pour into a greased 10-inch pie plate and bake for 40 minutes, until the top is nicely browned.
Let cool to room temperature on a wire rack, then chill in the refrigerator until cold, at least 1 hour. Serve with whipped cream or ice cream and additional toasted coconut, if desired.
