I made this recipe from Homesick Texan and it was great!
Pinto Bean Pie
1 1/2 cups of unseasoned cooked pinto beans (can use a one 15oz. can if you prefer)
1 cup of light brown sugar
1/2 cup (1 stick) of butter at room temperature
1 teaspoon vanilla
1 teaspoon cinnamon
1/4 teaspoon nutmeg
1/4 teaspoon allspice
1/4 teaspoon clove
A pinch of salt
1 unbaked 9-inch pie shell
Preheat the oven to 350 degrees.
In a blender, cream the sugar, butter and eggs.
Add the beans, and blend until it’s thick and smooth.
Add the spices and vanilla.
Pour pie filling into an unbaked pie shell, and bake for one hour or until an inserted knife comes out clean.
