Preheat oven to 350°F (175°C). Grease a 9 x 5-inch loaf pan.

In a large mixing bowl, combine flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.

In a blender, puree the extra-ripe bananas until you have 1 1/2 cups of banana puree.

Add the banana puree, melted margarine, lightly beaten eggs, and vanilla extract to the dry ingredients.

Mix until just blended. Do not overmix.

Stir in the semi-sweet chocolate pieces and chopped almonds.

Pour the batter into the prepared loaf pan.

Bake in the preheated oven for 60 to 65 minutes, or until a wooden pick inserted into the center comes out clean.

Remove the loaf from the pan and place it on a wire rack to cool completely before slicing and serving.
