Ingredients
Scale
- 2 cups (250 g) all-purpose flour 🌾
- 1 1/2 teaspoons baking powder 🥄
- 1/2 teaspoon baking soda 🥄
- 1/2 teaspoon kosher salt 🧂
- 3 ripe bananas, mashed (about 1 1/4 cups) 🍌
- 6 tablespoons unsalted butter, softened 🧈
- 3/4 cup (150 g) granulated sugar 🍚
- 1 large egg, room temperature 🥚
- 1/4 cup (61 g) buttermilk, room temperature 🥛
- 1 teaspoon vanilla extract 🍦
- 1 1/2 cups (approx. 260 g) mini chocolate chips, divided 🍫
- Paper liners for a 12-cup muffin tin 🧁
Instructions
- Preheat the oven to 425°F (220°C). Line a standard 12-cup muffin tin with paper liners and set aside.
- In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and kosher salt until evenly combined.
- In a small bowl, mash the ripe bananas with a fork until mostly smooth with a few small chunks remaining.
- In a stand mixer fitted with the paddle attachment (or using a hand mixer), cream the softened butter and granulated sugar on medium-high speed until light and fluffy, about 2 minutes. Scrape down the bowl as needed.
- Add the egg and mix until fully incorporated.
- Mix in the mashed bananas, buttermilk, and vanilla extract on low speed until just combined.
- Gradually add the dry ingredients to the wet ingredients and mix on low speed until just combined. Do not overmix — a few lumps are fine.
- Fold in 1 cup of the mini chocolate chips, reserving the remaining chips for topping.
- Scoop the batter evenly into the prepared muffin cups, filling each about 3/4 full. Sprinkle the reserved chocolate chips over the tops.
- Bake at 425°F (220°C) for 5 minutes. Without opening the oven door, reduce the temperature to 350°F (175°C) and continue baking for 13–16 more minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
- Serve warm or at room temperature. Store leftovers in an airtight container for up to 3 days, or freeze for longer storage.
