This is not a bread although baked in a loaf pan. It is a marvelous dessert.
2 cups sweet potatoes, peeled and boiled until tender
2 medium ripe bananas, peeled
2 tablespoons butter, melted
3 medium eggs, beaten
1/4 cup granulated sugar
1/4 cup molasses
1/2 teaspoon vanilla extract
1/2 teaspoon salt
1/4 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
1 cup whole milk
1/4 cup seedless golden raisins
Coarsely mash together sweet potatoes and bananas with a potato masher in a large mixing bowl; blend with an electric mixer until smooth.
Beat butter and eggs into the sweet potato-banana paste with a wire whisk to combine. Add sugar, molasses, vanilla extract, salt, cinnamon and nutmeg; whisk until well blended. Next whisk in the milk until it is incorporated. Stir in the raisins. Pour the batter into a 2-quart loaf pan and bake it in a preheated 350 degrees F oven until the center is firm and the top is golden brown, about 55 minutes.
Remove the "bread" from the oven and let it cool in the pan for 10 minutes before turning it out onto a plate. Serve generous slices of Pain Patate warm or chilled, with whipped cream or a little rum poured over the top, or plain.
Serves 6 or 8.
