1 cup all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 cup milk
Preheat oven to 400 degrees F (200 degrees C). Lightly grease a 9x13 inch baking pan.
In a medium bowl, mix together flour, baking powder, salt, milk and flour mixture. Mix on low speed until smooth, about 7 minutes. Stir in salt and milk as necessary until all flour is used. Transfer batter to prepared baking sheet.
Bake in preheated oven for 50 to 60 minutes, or until a toothpick inserted into center of the cake comes out clean. Allow to cool. Mince roasted bananas and optional brown sugar before serving.
