Ingredients
Dry Ingredients
- 3 cups all-purpose flour (measured properly, see notes)
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon fine sea salt
Wet Ingredients
- 1 1/4 cups buttermilk (room temperature)
- 1 1/4 cups granulated sugar
- 1/2 cup unsalted butter (melted)
- 2 large eggs (room temperature)
- 1/3 cup sour cream (room temperature)
- 1/3 cup vegetable oil
- 1 tablespoon vanilla bean paste or vanilla extract
Additional Ingredients
- 1 1/2 cups frozen wild Maine blueberries (do not thaw)
- 1/8 cup granulated sugar (for topping)
- Zest of 1/2 lemon (for topping)
Instructions
- Preheat the oven: Set the oven to 425°F (220°C). Line a 12-cup muffin pan with 6 liners and plan to bake in two batches to achieve perfect domed muffins.
- Mix dry ingredients: In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, and fine sea salt. Set aside for later use.
- Combine wet ingredients: In a separate large bowl, whisk together the buttermilk, granulated sugar, melted butter, eggs, sour cream, vegetable oil, and vanilla until the mixture is smooth and well blended.
- Combine wet and dry: Gradually add the wet ingredient mixture to the dry ingredients, mixing gently using a spatula or spoon until just combined. Avoid over-mixing to ensure tender muffins.
- Fold in blueberries: Carefully fold in the frozen wild Maine blueberries without thawing, distributing them evenly throughout the batter.
- Fill muffin liners: Fill each muffin liner to the top with batter to encourage a signature muffin top with a nice dome.
- Add topping: Mix the 1/8 cup granulated sugar with the lemon zest, then sprinkle this mixture evenly over the tops of the muffins for added flavor and sweetness.
- Bake: Bake initially at 425°F (220°C) for 5 minutes to set the muffin tops, then reduce the oven temperature to 350°F (175°C) and continue baking for an additional 15–18 minutes, or until the muffins turn golden brown and a toothpick inserted into the center comes out clean.
- Cool: Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. This prevents sogginess and preserves the texture.
Notes
- Measure flour properly by spooning it into the measuring cup and leveling it off to avoid dense muffins.
- Using frozen blueberries straight from the freezer prevents them from bleeding too much into the batter during mixing.
- Room temperature ingredients blend better and produce a more uniform batter.
- To make 12 muffins, bake in two batches if using only 6 liners at a time to ensure perfect domes for each muffin.
- For extra lemon flavor, you can add a teaspoon of lemon juice to the batter.
