Banana Cake with Caramel Sauce

In a blender, process the bananas, eggs, sugar, and oil until you achieve a smooth mixture.

In a separate bowl, sift the all-purpose flour with the baking powder (and cinnamon, if using).

Gently fold the blender mixture into the dry ingredients, stirring just until the batter is uniform.

Pour the batter into a greased and floured pan.

Bake the cake in a preheated oven at 350°F (180°C) for about 40 minutes, or until golden brown and firm to the touch.

After removing from the oven and letting it cool slightly, top the cake with a generous layer of dulce de leche.
