These are the department store blueberry muffins everyone remembers: tender, loaded with berries, and crowned with a thin, shatteringly crisp sugar crust. The batter comes together fast and bakes into bakery-worthy muffins with a sky-high dome.

I love that they use basic staples and a quick cream-the-butter start. No long resting time, no special equipment beyond a hand mixer, and the result tastes like you lined up at a bakery counter.

Why These Muffins Work So Well

The buttermilk keeps the crumb soft and almost cakey, while the real star is that generous sprinkle of granulated sugar on top before baking. It melts just enough to form a glossy, crackly shell that contrasts with the fluffy interior.

Beating the butter and sugar until pale whips air into the batter, which helps the muffins rise tall. Using fresh or frozen blueberries means you can make them year-round, and the amount of berries in the batter is generous without making the muffins wet.

Ingredients

1/2 cup (1 stick) unsalted butter, softened: take it out of the fridge 30 minutes ahead so it creams easily
1 cup granulated sugar: plus about 2 to 3 tablespoons for the tops
2 large eggs: room temperature for smoother mixing
1 teaspoon vanilla extract
2 cups all-purpose flour: spoon flour into the measuring cup and level it off
2 teaspoons baking powder
1/2 teaspoon fine sea salt
1/2 cup buttermilk: well shaken, not thin or watery
1 1/2 cups fresh blueberries: or frozen, do not thaw first

Variations / Substitutions

No buttermilk?: stir 1 1/2 teaspoons lemon juice or white vinegar into 1/2 cup whole milk and let it sit 5 minutes.
Frozen blueberries: use them straight from the freezer and toss them with 1 tablespoon of flour before folding in to reduce sinking.
Lemon boost: rub 1 teaspoon lemon zest into the sugar before creaming for a citrusy note.
Whole wheat option: swap up to half of the all-purpose flour with white whole wheat flour; the muffins will be slightly heartier.

How to Make Jordan Marsh Blueberry Muffins

Step 1: Cream the Butter and Sugar

Heat the oven to 400°F (200°C). Line a standard 12-cup muffin tin with paper liners or butter the cups well. In a large bowl, beat the softened butter and the 1 cup sugar with a hand mixer on medium speed until the mixture looks light and fluffy, about 3 minutes. Scrape down the sides of the bowl once or twice.

The butter and sugar should turn pale yellow and almost mousse-like. That air you just beat in will expand in the oven and give the muffins their high tops.

Step 2: Beat in the Eggs and Vanilla

Add the eggs one at a time, beating each until fully blended before adding the next. Then mix in the vanilla extract. After this step, the batter will be smooth and a little glossy.

Take care not to overbeat here; just combine until the egg disappears. A silky, even texture means the sugar has started to dissolve into the moisture, which helps the muffin crumb stay tender.

Step 3: Alternate the Dry Ingredients and Buttermilk

In a separate medium bowl, whisk the flour, baking powder, and salt together. Add the dry mixture to the butter mixture in three parts, alternating with the buttermilk in two parts. Start and end with the flour. Mix with a spatula or the mixer on low speed just until the streaks of flour disappear after each addition.

The batter will become thick and a bit sticky, not pourable like pancake batter. That density holds the blueberries in place and builds structure for the domed top.

Step 4: Fold in the Blueberries

Scatter the blueberries over the batter. Use a flexible spatula to fold them in gently, turning the batter over on itself until the berries are evenly spaced. A few faint flour streaks are fine; they will hydrate in the oven.

If you are using frozen blueberries, toss them with 1 tablespoon of flour first to keep them from sinking to the bottom. Work quickly so your hands do not warm the berries.

Step 5: Fill, Sugar, and Bake

Divide the batter evenly among the 12 muffin cups. They will be nearly full, which helps them rise tall. Sprinkle about 1 teaspoon of granulated sugar over each muffin. Bake until the tops are deep golden and a toothpick poked in the center of a muffin comes out with a few moist crumbs, 20 to 24 minutes.

Let the muffins cool in the pan for 5 minutes before you carefully lift them out onto a wire rack. Serve them warm, while the sugar tops still have a delicate crackle.

Tips for That Crackly Sugar Top

Use room temperature ingredients: cold butter won’t fluff up properly, so the muffins can turn out dense. Set the butter and eggs on the counter while you preheat the oven.
Don’t overwork the flour: stirring too long develops gluten and makes the crumb tough. Stop the second you no longer see dry flour.
Pack the berries high: a full 1 1/2 cups ensures every bite gets fruit, but more than that can weigh the muffins down.
Stick with granulated sugar for the top: a fine dusting of regular white sugar melts into that shiny crust. Coarse sugars stay grainy rather than creating a shell.

Bake times by muffin size:

Pan or size	Bake time at 400°F (200°C)
Standard 12-cup tin	20 to 24 mins
Jumbo 6-cup tin	25 to 28 mins
Mini muffin tin	12 to 15 mins

Storing Leftover Muffins

Refrigerate: keep muffins in an airtight container at room temperature for up to 2 days. After that, move them to the fridge so the fruit stays fresh, up to 5 days. The sugar top will soften over time.
Reheating: warm a muffin in a 300°F (150°C) oven for 5 to 7 minutes to crisp the top again, or microwave for 15 to 20 seconds if you are in a rush.

Frequently Asked Questions

Can I use oil instead of butter?

Yes, but you will lose the creamed-butter lift and the crisp sugar crust won’t form the same way. The muffins will be softer and more cakelike.

Why did my blueberries all sink to the bottom?

The batter might have been too thin or you stirred too vigorously. Tossing the berries in a little flour and folding them in gently with a spatula solves this.

How do I get a taller dome on my muffins?

Fill the muffin cups nearly to the top and start baking at 400°F (200°C). The high heat gives a quick burst of rise that creates that rounded bakery top.

Can I make these gluten-free?

I have had good results with a 1-to-1 gluten-free flour blend that contains xanthan gum. The texture is slightly more fragile, but the sugar top still works.
