Full Ingredients

Blueberry Muffin Batter

• 2 cups (240 g) all-purpose flour, spooned and leveled
• 2 tsp baking powder
• 1/4 tsp baking soda
• 1/2 tsp fine sea salt (or table salt)
• 1 cup (200 g) granulated sugar
• 1/2 cup (113 g) unsalted butter, melted and cooled until just warm
• 1/2 cup (120 ml) sour cream or full-fat plain yogurt, room temperature
• 1/2 cup (120 ml) whole milk, room temperature
• 2 large eggs, room temperature
• 2 tsp pure vanilla extract
• 1 3/4 cups (about 260 g) blueberries, fresh or frozen (do not thaw frozen berries)
• 2 tsp all-purpose flour (for tossing with frozen blueberries only)

Sugar-Crusted Tops

• 2–3 tbsp coarse sugar (turbinado or demerara) for sprinkling on top

Step-by-Step Instructions

Step 1: Prep your pan and preheat the oven

Position a rack in the center of your oven. Preheat to 425°F (220°C). This initial high heat helps create tall, high-domed muffins.

Line a standard 12-cup muffin pan with paper liners. If you prefer not to use liners, generously grease each cup with butter or nonstick spray, making sure to coat the top surface of the pan as well (this prevents the muffin tops from sticking as they rise and spread slightly over the edges).

Set the prepared pan aside while you mix the batter.

Step 2: Combine the dry ingredients

In a medium bowl, whisk together the 2 cups flour, 2 tsp baking powder, 1/4 tsp baking soda, and 1/2 tsp salt until everything is evenly distributed and lump-free. This ensures the leaveners are spread throughout the batter so your muffins rise evenly.

If you are using frozen blueberries, place them in a small bowl and toss with 2 tsp flour. This light coating helps keep them from bleeding too much into the batter and sinking to the bottom. If you are using fresh berries, you can skip this step.

Step 3: Whisk the wet ingredients

In a large mixing bowl, add the 1 cup sugar and 2 eggs. Whisk vigorously until the mixture looks slightly thickened and lightened in color, about 30–45 seconds by hand. This step helps create structure and a tender crumb.

Whisk in the melted and cooled butter until fully combined. Then add the sour cream, milk, and vanilla extract. Whisk until the mixture is smooth and creamy, with no streaks of sour cream remaining. Scrape down the sides of the bowl as needed so everything is well blended.

Step 4: Gently bring the batter together

Add the dry ingredient mixture to the wet ingredients in the large bowl. Using a silicone spatula or wooden spoon, fold the dry ingredients into the wet using gentle, sweeping motions. Turn the bowl as you go.

Stop as soon as you no longer see dry flour. A few small lumps in the batter are fine. Avoid overmixing, which can make the muffins tough and dense. The batter should be fairly thick, not runny.

Step 5: Fold in the blueberries and rest the batter

Add the blueberries to the batter. If using frozen berries, add them straight from the freezer (they should already be lightly floured). Gently fold them in with just a few strokes, trying not to break them up too much. The batter will thicken slightly as the berries are incorporated.

For the best high-domed muffins, let the batter rest in the bowl at room temperature for 10–15 minutes. This short rest allows the flour to hydrate and the leaveners to start working, which encourages a taller rise in the oven.

Step 6: Fill the muffin cups and add the sugar crust

After the batter has rested, give it one very gentle stir. Using a large spoon or scoop, divide the batter evenly among the 12 muffin cups. For bakery-style domes, fill each cup almost to the top, about 3/4 to slightly more full.

Sprinkle the tops generously with 2–3 tbsp coarse sugar, dividing it evenly. The sugar will melt slightly and bake into a crisp, golden crust that contrasts beautifully with the soft muffin interior.

Step 7: Bake, cool, and enjoy

Place the muffin pan into the preheated 425°F (220°C) oven and bake for 5–7 minutes. Without opening the oven door, reduce the oven temperature to 350°F (175°C) and continue baking for an additional 13–15 minutes, or until the muffins are well domed, the tops are golden, and a toothpick inserted into the center of a muffin comes out with just a few moist crumbs.

Remove the pan from the oven and let the muffins cool in the pan for 5–10 minutes. Carefully transfer them to a wire rack to finish cooling, or enjoy warm while the tops are still extra crisp and the blueberries are juicy and tender.

Pro Tips

• Room-temperature ingredients rise better: Let your eggs, sour cream, and milk sit out for 20–30 minutes before baking so they blend smoothly into the batter.
• Do not overmix: Mix just until the flour disappears, then stop. Overmixing develops gluten and can lead to tough, peaked muffins instead of tender, domed ones.
• High heat for high domes: Starting at 425°F then lowering the temperature creates a quick burst of steam that lifts the muffin tops for that bakery look.
• Frozen vs. fresh blueberries: Frozen berries work beautifully; just do not thaw them. Toss in a little flour and fold in gently to limit color streaking.
• Adjust sweetness on top: For a thicker, crunchier crust, be generous with the coarse sugar; for a lighter finish, use just a light sprinkle.

Variations

• Lemon Blueberry Muffins: Add 1–2 tbsp finely grated lemon zest to the wet ingredients and replace 2 tbsp of the milk with freshly squeezed lemon juice. Garnish the baked muffins with a light lemon glaze if you like.
• Streusel-Topped Muffins: Instead of coarse sugar, top each muffin with a simple streusel made from 1/3 cup flour, 1/3 cup brown sugar, 1/4 tsp cinnamon, and 3 tbsp cold butter rubbed together until crumbly.
• Mini Muffins: Use a mini muffin pan and bake at 400°F (200°C) for 9–12 minutes, or until golden and set. Reduce the coarse sugar topping slightly so it does not overpower the smaller muffins.

Storage & Make-Ahead

Allow muffins to cool completely before storing. Keep them in an airtight container at room temperature for up to 3 days. To maintain the crisp sugar tops, line the container with a paper towel and leave the lid slightly ajar for the first few hours to let excess steam escape.

For longer storage, freeze the cooled muffins in a single layer until solid, then transfer to a freezer bag or container for up to 2 months. Thaw at room temperature or warm in a 300°F (150°C) oven for 8–10 minutes. If you want to bake ahead, you can also refrigerate the unbaked batter in the muffin pan (already portioned) for up to 12 hours; bake straight from the fridge, adding 1–2 extra minutes to the baking time.
