These homemade blueberry muffins are impossibly moist, bursting with fresh blueberries, and topped with a golden sugar crust. The easiest quick blueberry muffin recipe you will ever make.

If you have been searching for the best blueberry muffin recipe, the search ends right here. These homemade blueberry muffins have everything you want: a sky-high domed top, a sparkling sugar crust that crackles when you bite into it, a tender and impossibly moist crumb, and pockets of sweet-tart blueberries in every single bite. Whether you are a seasoned baker or making muffins from scratch for the very first time, this easy blueberry muffin recipe is completely foolproof.
These are the kind of muffins that make your kitchen smell like a proper bakery on a slow weekend morning. The kind people ask you to bring to every brunch, bake sale, and family gathering. Once you learn how to make homemade blueberry muffins this way, the boxed mix versions will never tempt you again.
Most quick blueberry muffin recipes use only butter or only oil. This recipe uses both, and that is the first secret to their incredible texture. Butter delivers rich, unmistakable flavor. Oil keeps the crumb moist for days, long after a butter-only muffin would have turned dry and crumbly.
The second secret is sour cream. It adds a subtle tang that balances the sweetness of the blueberries, and its thick, creamy fat content makes the interior of each muffin almost custardy. Greek yogurt works as a straight swap if that is what you have on hand.
The third secret is a two-temperature bake. Starting the muffins at a higher heat, 425 degrees F, causes them to rise rapidly in the first few minutes, creating that gorgeous bakery-style dome. Then you drop the temperature to finish baking them through gently without drying them out. It is a simple trick that makes a dramatic difference.
Chef's Tip: Never skip the step of tossing your blueberries in a little flour before folding them into the batter. This coating prevents them from sinking straight to the bottom of your muffins during baking.
Both work wonderfully here, which is great news because this can be your go-to easy blueberry muffins recipe year-round. When fresh blueberries are in season, use them without hesitation. Rinse them and dry them very thoroughly on paper towels before adding them to the batter.
For frozen blueberries, the rules are a little different:
Thawing frozen berries releases their juices into the batter, which turns everything an unappetizing grayish-purple and makes the muffins gummy. Keep them frozen and you will get perfectly defined, jewel-like pockets of blueberry in every bite.
For consistently tall, evenly baked muffins, a good heavy-gauge muffin tin is worth every penny. A flimsy pan warps in a hot oven and creates uneven heat distribution. Using quality paper liners also prevents the muffins from sticking and makes cleanup effortless.
Before you dive in, a few things that will guarantee your muffins come out perfect every single time:
Use room temperature ingredients. Cold eggs and cold sour cream do not emulsify properly with the butter and oil, which leads to a dense, uneven batter. Pull your dairy items out of the fridge about 30 minutes before you start.
Do not overmix. This is the golden rule of muffin baking. Once the wet and dry ingredients meet, stir only until the last streak of flour disappears. Overmixing develops the gluten in the flour and turns muffins tough and rubbery.
Fill the cups generously. Unlike cupcakes, muffins are meant to be filled nearly to the top. A full cup is what gives you that beautiful dome.
Do not skip the coarse sugar topping. That simple sprinkle of turbinado or demerara sugar creates a crunchy, sparkling crust on top that takes these from homemade to bakery-worthy in one small step.
Chef's Tip: For extra-tall muffin tops, let the filled muffin tin rest at room temperature for 10 to 15 minutes before it goes into the oven. This short rest gives the leavening a head start.
Ready to bake the most moist, golden, blueberry-packed muffins of your life? Here is the full step-by-step recipe:

These homemade blueberry muffins are impossibly moist, bursting with fresh blueberries, and topped with a golden sugar crust. The easiest quick blueberry muffin recipe you will ever make.
Preheat your oven to 425 degrees F (220 degrees C). Line a standard 12-cup muffin tin with paper liners or grease it generously with nonstick spray.
In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
In a separate medium bowl, whisk the granulated sugar, melted butter, and oil together until well combined. Add the eggs one at a time, whisking after each addition, then whisk in the sour cream, milk, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula until just combined. A few streaks of flour are perfectly fine. Do not overmix.
Toss the blueberries with 1 teaspoon of the flour mixture to coat them lightly, then fold them gently into the batter.
Divide the batter evenly among the 12 muffin cups, filling each nearly to the top. Sprinkle coarse sugar generously over each muffin.
Bake at 425 degrees F for 5 minutes, then, without opening the oven, reduce the temperature to 375 degrees F (190 degrees C) and continue baking for 15 to 17 minutes, until the tops are golden and a toothpick inserted in the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes before transferring to a wire rack. Serve warm or at room temperature.
These muffins are at their absolute peak about 20 minutes out of the oven, when the tops are still slightly crisp and the blueberries are warm and jammy inside. Serve them as-is, or split one open and spread with a little salted butter for pure breakfast heaven.
Storing: Keep in an airtight container at room temperature for up to 3 days. To revive a day-old muffin, pop it in the microwave for 15 to 20 seconds and it will taste freshly baked.
Freezing: These freeze exceptionally well. Cool completely, then store in a zip-lock freezer bag for up to 3 months. Thaw at room temperature or microwave straight from frozen for about 45 to 60 seconds.
Make-Ahead Morning Hack: Mix your dry ingredients in one bowl and your wet ingredients in another the night before. Cover and refrigerate the wet mixture. In the morning, combine, fold in the berries, and bake. Fresh muffins in under 30 minutes with barely any morning effort.
