Ingredients
Scale
- 2 and 3/4 cups (330g) all-purpose flour
- 1 tablespoon (14g) baking powder
- 1/2 teaspoon salt
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground cinnamon
- 1 cup (227g) unsalted butter, melted and slightly cooled
- 1/2 cup (106g) light brown sugar, packed
- 1/2 cup (99g) granulated sugar
- 3 large eggs, room temperature
- 2 teaspoons pure vanilla extract
- 3/4 cup (170g) full-fat sour cream
- 1 cup (227g) mashed ripe banana
- 1 pint (292g) fresh blueberries
- 1/2 cup toasted walnuts, finely chopped
- 2 tablespoons sparkling sugar, optional
Instructions
- Preheat the oven to 400 degrees F and line a 12-cup muffin tin with paper liners.
- In a large bowl, sift together the flour, baking powder, nutmeg, cinnamon, and salt; set aside.
- In another large bowl, whisk together the melted butter, both sugars, eggs, vanilla extract, sour cream, and mashed bananas until smooth.
- Combine the dry ingredients with the wet ingredients using a rubber spatula until just mixed. Avoid over-mixing to keep muffins moist.
- Gently fold in the blueberries and walnuts until just combined.
- Spoon the batter into the muffin tins, filling each cup to the top.
- Add a few extra blueberries on top of each muffin and sprinkle with sparkling sugar if desired.
- Bake in the center of the middle rack for 24 to 26 minutes, until puffed and golden brown. A toothpick inserted should come out clean or with a few moist crumbs.
- Let the muffins cool in the pan for at least 15 minutes before enjoying or transferring to a cooling rack.
Notes
For best results, use ripe bananas for sweetness and moisture.
You can substitute walnuts with your favorite nuts or omit them for a nut-free version.
Store leftover muffins in an airtight container for up to 3 days.
