Ingredients
Wet Ingredients:
- 100g room temp butter
- 150g dark brown sugar
- 100g Sourdough discard or active starter
- 2 large eggs
- 2 tsp vanilla extract or vanilla paste
- 300–350g (3 large) ripe bananas, smashed
Dry Ingredients:
- 190g all-purpose flour
- 50g unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp salt
- 1 tsp espresso powder
- 240g chocolate chips and chopped chocolate
Instructions
Step 1: Prep Your Ingredients
Preheat your oven to 350°F (175°C). Grease or line a standard 9×5 loaf pan with parchment paper for easy removal.
Step 2: Cream Butter and Sugar
In a stand mixer or large mixing bowl, beat the softened butter and dark brown sugar together until light and fluffy. This step helps create a tender crumb.
Step 3: Add the Wet Ingredients
Mix in the sourdough discard, eggs, vanilla extract, and smashed bananas. Blend until well combined. The mixture may look a little lumpy from the bananas, and that’s okay.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, baking soda, salt, espresso powder, and 200g of the chocolate chips. Reserving some chocolate chips ensures a chocolate-studded top for your loaf.
Step 5: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can make your bread dense.
Step 6: Prepare for Baking
Pour the batter into your prepared loaf pan, smoothing the top with a spatula. Sprinkle the remaining 40g of chocolate chips over the top for a bakery-worthy finish.
Step 7: Bake
Bake in the preheated oven for 60–75 minutes, or until a toothpick inserted into the center comes out clean. The exact baking time may vary depending on your oven and pan size, so start checking around the 60-minute mark.
Step 8: Cool and Enjoy
Let the banana bread cool in the pan for 10–15 minutes before transferring it to a wire rack to cool completely. Slice, serve, and enjoy the rich chocolatey goodness!
