Ingredients:
- 3 large over-ripe bananas (approx. 450g)
- 1/2 cup (115g) unsalted butter, melted and cooled
- 3/4 cup (150g) light brown sugar, packed
- 1 large egg, room temperature
- 1 tsp (5ml) pure vanilla extract
- 1 1/2 cups (190g) all-purpose flour, sifted
- 1 tsp (5g) baking soda
- 1 tsp (5g) baking powder
- 1/2 tsp (3g) sea salt
- 1 tsp (2.6g) ground cinnamon
- 1 cup (120g) chopped walnuts, divided
- 1 tbsp (12g) turbinado sugar for topping
Instructions:
- Preheat your oven to 350°F (175°C). Toast the chopped walnuts in a dry pan or on a baking sheet for 5 minutes until fragrant and slightly darkened to release essential oils.
- In a large mixing bowl, mash the 3 large bananas with a fork or potato masher until velvety and liquid.
- Whisk the melted unsalted butter and packed light brown sugar into the mashed bananas until thoroughly combined.
- Add the room temperature egg and vanilla extract to the wet mixture, whisking vigorously until the mixture is emulsified.
- In a separate bowl, sift together the all-purpose flour, baking soda, baking powder, sea salt, and ground cinnamon.
- Gently fold the dry ingredients into the wet ingredients using the 'muffin method'—mix only until just combined to avoid a dense crumb.
- Fold in 90g of the toasted walnuts, reserving the remaining 30g for the topping.
- Line a 12-cup standard muffin tin with paper liners. Distribute the batter evenly among the cups until three quarters full.
- Sprinkle the tops with the remaining toasted walnuts and the turbinado sugar for a crunchy, shattering crust.
- Bake for 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Transfer to a wire cooling rack after 5 minutes.
