Prep & Cook Time
- Prep Time: 5 minutes
- Cook Time: 35 minutes
- Total Time: 40 minutes
- Servings: 12 muffins
Ingredients
- cooking spray
- 2 ¼ cups all-purpose flour
- 3/4 tsp salt
- 1 tbsp baking powder
- ¼ tsp baking soda
- 1¼ cup granulated sugar
- 1/2 cup unsalted butter (softened)
- 2 large eggs (room temperature)
- 1 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 2 tsp lemon zest
- ⅔ cup full-fat buttermilk* (room temperature (plus 1 tbsp more if needed))
- 1½ cups blueberries (fresh or frozen (see note), washed and dried)
- ¼ cup turbinado sugar (for topping)
Instructions
- Preheat your oven to 375°F (190°C). Prepare a standard 12-cup muffin tin by generously spraying each cup with cooking spray.
- In a medium bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
- In a large bowl, use a hand mixer or stand mixer to cream the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
- Beat in the eggs one at a time, fully incorporating each before adding the next. Then, mix in the vanilla powder (use half this amount if you prefer less rich vanilla flavor) and lemon zest.
- With the mixer on low speed, add about one-third of the dry flour mixture, mixing until just combined. Then, add half of the buttermilk and mix. Repeat with another third of the flour, the remaining buttermilk, and finally the last third of the flour. The batter will be thick. If it seems excessively dry, mix in the optional extra tablespoon of buttermilk.
- Gently fold in the blueberries by hand using a spatula, being careful not to overmix and crush them.
- Divide the batter evenly among the 12 prepared muffin cups. The cups will be very full. Generously sprinkle the top of each muffin with turbinado sugar.
- Bake for 30-35 minutes, or until the tops are golden brown and a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs (but no wet batter).
- Allow the muffins to cool in the pan for 10 minutes before carefully transferring them to a wire rack to cool completely.
Variations
- Lemon Glaze: For extra citrus sweetness, drizzle cooled muffins with a simple glaze made from powdered sugar and fresh lemon juice.
- Crumb Topping: Swap the turbinado sugar for a classic crumb topping by rubbing together a few tablespoons of flour, sugar, and cold butter until crumbly before baking.
- Mini Muffins: Bake as mini muffins for a bite-sized treat, reducing the baking time to about 12-15 minutes.
- Double Berry: Replace half of the blueberries with an equal amount of diced strawberries or raspberries for a mixed berry flavor.
Tips for Success
- For the most tender muffins, ensure your buttermilk, eggs, and butter are truly at room temperature before you begin.
- Toss frozen blueberries in a tablespoon of the measured flour before folding them in to help prevent them from sinking and bleeding too much color.
- Avoid overmixing the batter once the flour is added. Mix only until the ingredients are just combined for a soft, delicate texture.
- Use a cookie scoop or large spoon to transfer the batter easily into the muffin tin, helping to keep things tidy and uniform.
Storage & Reheating
Store completely cooled muffins in an airtight container at room temperature for up to 3 days. For longer storage, freeze them for up to 3 months. To reheat, warm a muffin in the microwave for 15-20 seconds or in a 300°F oven for 5-10 minutes until warm.
FAQ
Can I use frozen blueberries?
Yes. Use them directly from the freezer without thawing to prevent them from turning the entire batter purple. Gently fold them in at the last moment.
What can I use if I don’t have buttermilk?
The recipe relies on buttermilk for the proper texture. You can make a quick substitute by adding 2 teaspoons of white vinegar or lemon juice to ⅔ cup of whole milk. Let it sit for 5-10 minutes before using.
Why are my muffins dense?
This is usually caused by overmixing the batter after adding the flour, which develops the gluten. Mix only until the dry ingredients are just incorporated.
Can I make this as a loaf?
Yes, you can bake this as a blueberry bread. Pour the batter into a greased 9×5-inch loaf pan and bake at 350°F for 50-60 minutes, or until a tester comes out clean.
What is the purpose of the lemon zest?
The lemon zest doesn’t make the muffins taste overtly lemony; instead, it brightens the flavor of the blueberries and cuts through the sweetness beautifully.
Can I reduce the sugar?
The sugar amount is integral to the texture and browning. Reducing it significantly may result in a drier muffin with less of that signature domed top and crisp sugar crust.
