Ingredients
- Ingredients
- 3 cups (360 grams) all-purpose flour
- 1 Tablespoon (14 grams) baking powder
- 1/2 teaspoon salt
- 1/4 teaspoon freshly grated nutmeg
- 1/4 teaspoon ground cinnamon
- 1/2 cup (113 grams) unsalted butter, melted and slightly cooled
- 1/2 cup (106 grams) light brown sugar, packed
- 1/2 cup (99 grams) granulated sugar
- 2 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 3/4 cup (170 grams) full-fat sour cream
- 1 cup (227 grams) mashed ripe banana
- 1 pint (292 grams) fresh blueberries
- 1/2 cup toasted walnuts, finely chopped
- 2 Tablespoons sparkling sugar, optional
- Instructions
-
- Preheat oven to 400 degrees (F). Line a 12 cup muffin tin with paper liners and it set aside.
- In a large bowl, sift together the flour, baking powder, nutmeg, cinnamon, and salt; set aside.
- In a separate large bowl, whisk together the melted butter, both sugars, eggs, vanilla extract, sour cream, and mashed bananas, mixing until ingredients are fully incorporated
- Add the dry mixture of ingredients to the wet mixture of ingredients and, using a rubber spatula, mix until just combined. Do not over mix or your muffins will be dry!
- Fold in the blueberries and walnuts, mixing just until combined.
- Divide the batter evenly among prepared muffin tins, filling each tin all the way to the top.
- Press a few extra blueberries into the top of each muffin and then add sprinkle with sparkling sugar, if using.
- Bake, in the center of the middle rack, for 24 to 26 minutes, or until the tops are puffed up and richly golden brown, and a toothpick inserted in the middle comes out clean, or with a just a few moist crumbs attached.
- Cool muffins at least 15 minutes in the pan before serving warm or transferring to a cooling rack.
- NOTES
- If your oven runs hot, bake at 375, for 25 to 26 minutes, or until golden brown and bake though.
- Bake muffins on a rack, positioned in the middle of your oven.
- If you frequently have burnt muffin bottoms, I suggest placing your muffin tin on baking sheet before baking. The baking sheet will help prevent this!
