Preheat your oven to 350°F (175°C) and line a loaf pan with parchment paper.

In a large mixing bowl, combine the melted creamy peanut butter, sugar, and mashed bananas. Beat in the vegetable oil and eggs until the mixture is smooth.

Sift together cocoa powder, baking soda, and salt, then gently fold the dry ingredients into the wet mixture.

Carefully fold in the all-purpose flour until just combined.

Pour the batter into your prepared loaf pan and layer sliced bananas on top.

Bake for approximately 55 minutes or until a knife inserted into the center comes out clean.

Let cool in the pan for about 20 minutes, then drizzle with additional melted peanut butter before serving.
