These take about ten minutes of actual work and one bowl more than I’d like. High heat for the first five minutes is what gives you the tall bakery dome, and that’s basically the whole secret, so let’s get to it.
If you want the longer explanation of muffin method — why the wet and dry stay apart until the last moment, what overmixing does to the crumb — I went through all of that in the banana nut muffins post. No point repeating it here.
Ingredients
- 2 cups all-purpose flour
- 3/4 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 2 large eggs, room temperature
- 1/2 cup whole milk
- 1/2 cup sour cream or plain yogurt
- 1/3 cup melted butter, slightly cooled
- 1/4 cup neutral oil
- 2 teaspoons vanilla extract
- 1 1/2 cups chocolate chips, plus more for topping
Instructions
- Preheat your oven to 425 degrees F and line a 12-cup muffin tin with paper liners or grease it well.
- In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly combined.
- In a separate bowl, whisk the eggs, milk, sour cream, melted butter, oil, and vanilla until smooth.
- Pour the wet ingredients into the dry and fold gently with a spatula, stopping while the batter is still lumpy. Overmixing makes tough muffins.
- Fold in the chocolate chips with just a few strokes, distributing them without deflating the batter.
- Divide the batter among the cups, filling each nearly to the top. Sprinkle extra chocolate chips over each one.
- Bake at 425 degrees F for 5 minutes, then, without opening the oven, reduce the heat to 375 degrees F and bake for another 13 to 15 minutes.
- The muffins are done when the tops are golden and a toothpick inserted in the center comes out with a few moist crumbs.
- Let them cool in the pan for 5 minutes, then transfer to a wire rack.
The Two-Temperature Trick, Briefly
That blast at 425F sets the outer edge of each muffin fast while the middle is still liquid, so the only direction the rising batter can go is up. Drop to 375F and the inside cooks through without the crown scorching. If you bake the whole thing at 375F you get perfectly nice muffins with flat tops. I’ve done it by accident more than once and nobody complained, but the domes are the reason to bother.
Two things break it. Opening the oven during those first five minutes, which dumps the heat you’re relying on. And underfilling the cups: these want to be filled nearly level with the rim, not two-thirds, or there isn’t enough batter to push a dome. Twelve cups, right to the top. A standard 1/3-cup scoop gets you there in one go.
Why Your Chips End Up at the Bottom
Because they’re denser than the batter and the batter is thin enough to let them travel. Two fixes, both quick.
Take a tablespoon out of the measured flour before you whisk the dry ingredients, and toss the chips in it until they’re dusty. The coating grabs the batter and slows the sink. Second, use mini chips if you have them — less mass each, and you get chocolate in more bites, which I prefer anyway. The extra handful scattered on top before baking is not decoration; it guarantees the first bite has chocolate in it regardless of what happened underneath.
Sour cream is doing real work here too. It thickens the batter, and a thicker batter holds the chips in suspension. Swapping it for milk makes the whole thing looser and the chips drop.
Tomorrow, and Three Weeks From Now
Airtight box, one sheet of kitchen paper underneath and one on top, room temperature. They stay good for 2 days. The paper matters more than the box — muffins sweat as they cool and that moisture makes the liner slide off and the tops go tacky, so cool them completely on the rack first, at least 40 minutes.
For the freezer: bag them whole once fully cold, up to 3 months. From frozen, 25 to 30 seconds in the microwave brings one back convincingly, and the chips go molten again, which fresh ones don’t do after the first hour. That’s the one way a frozen muffin beats a fresh one.
For a version with fruit and a crunchy top instead, the blueberry streusel muffins use the same tin and the same folding rule. And if what you actually wanted was chocolate chips in something chewier, go and make brown butter chocolate chip cookies instead.
