Ingredients:
- 3 large overripe bananas (approx. 450g)
- 1/2 cup (125g) creamy peanut butter
- 1/3 cup (75g) unsalted butter, melted
- 3/4 cup (150g) brown sugar, packed
- 1 large egg, room temperature
- 1 tsp vanilla extract
- 1.5 cups (190g) all-purpose flour
- 1/2 cup (45g) unsweetened Dutch-processed cocoa powder
- 1 tsp baking soda
- 1/2 tsp fine sea salt
- 3/4 cup (130g) semi-sweet chocolate chips
Instructions:
- Prepare the environment. Preheat your oven to 350°F (175°C). Line your 9x5 inch loaf pan with parchment paper. Note: This ensures even heat and an easy release.
- Liquefy the fruit. In a large mixing bowl, mash the 3 large bananas until they are completely smooth and liquid.
- Emulsify the wet base. Whisk in the 75g melted butter, 125g peanut butter, 150g brown sugar, egg, and vanilla. Whisk until the mixture looks glossy and smooth.
- Sift the dry goods. In a separate bowl, whisk together the 190g flour, 45g cocoa, baking soda, and salt. Note: Cocoa clumps are stubborn; make sure they are gone.
- The Wet Fold. Gently fold the dry ingredients into the wet mixture using a spatula. Stop as soon as you see the last streak of white flour disappear.
- Add the texture. Fold in the 130g chocolate chips. The batter should be thick, dark, and smell intensely of cocoa.
- Fill the pan. Pour the batter into the prepared loaf pan, smoothing the top with your spatula.
- Create the swirl. Dollop the remaining 32g of peanut butter on top. Use a butter knife to swirl it in a figure eight pattern.
- Bake for 60 minutes. Bake until a skewer inserted into the center comes out with only a few moist crumbs.
- The Rest. Let the loaf cool in the pan for 15 minutes. This allows the structure to set so it doesn't fall apart when you lift it out. Smell Checkpoint 1: At 20 minutes, you’ll start to smell the sweet, fruity aroma of the bananas. Smell Checkpoint 2: At 45 minutes, the cocoa scent will deepen, and you'll catch the distinct toasted smell of the peanut butter swirl on top.
