Double Chocolate Muffins Recipe (Moist, Bakery-Style)

These are the chocolate muffins you buy at a good coffee shop: tall, dark and domed, with a tender, moist crumb and pockets of melted chocolate in every bite. They are rich enough to feel like a treat but not as sweet as cupcakes, so they work for breakfast, lunch boxes or an afternoon coffee.

Everything is mixed by hand in one bowl in about fifteen minutes. The two things that make the difference are blooming the cocoa in hot liquid, which brings out a much deeper chocolate flavor, and a short blast of high oven heat, which pushes the batter up into those big bakery tops.

Why this recipe works

• Blooming cocoa powder in hot coffee or water releases its flavor, so the muffins taste of real chocolate rather than dry cocoa.
• Vegetable oil keeps the crumb soft and moist for days, even straight from the refrigerator.
• Sour cream or buttermilk adds tenderness and a little tang that balances the sweetness.
• Starting at 425°F makes the batter rise fast and dome before the crust sets; finishing at 350°F bakes the centers through.

Ingredient notes

Use natural unsweetened cocoa or Dutch-process cocoa; Dutch-process gives a darker color and smoother flavor. The coffee does not make the muffins taste like coffee; it only intensifies the chocolate. Use hot water if you prefer.

Semisweet chocolate chips are classic. Mini chips stay suspended in the batter more evenly, and chopped dark chocolate gives bigger melted pools. Save a couple of tablespoons of chips to press onto the tops before baking, so they look as good as they taste.

How to get tall, domed muffin tops

Fill every cup right to the rim; the batter needs to be heaped to rise above the pan. Let the batter rest for 15 minutes before scooping if you have time, which thickens it so it climbs rather than spreads. Then bake at 425°F for 5 minutes and lower the oven to 350°F without opening the door for the rest of the bake.

How to tell when chocolate muffins are done

Color is no help with chocolate batter, so test instead. A toothpick inserted into the center should come out with a few moist crumbs but no wet batter; melted chocolate from a chip can fool you, so try a second spot. The tops should spring back when pressed lightly. An instant-read thermometer should read about 205°F.

How to store double chocolate muffins

• Store in an airtight container at room temperature for up to 3 days. Place a paper towel under and over them to keep the tops from getting sticky.
• Freeze in a zip-top bag for up to 3 months. Thaw at room temperature or warm for 20 seconds in the microwave.

Variations to try

• Triple chocolate: use a mix of semisweet, white and milk chocolate chips.
• Chocolate banana: replace the sour cream with 3/4 cup mashed ripe banana.
• Mocha: dissolve 1 teaspoon instant espresso in the hot coffee.
• Streusel top: sprinkle with a mix of flour, brown sugar, cocoa and cold butter before baking.

Frequently asked questions

Why are my chocolate muffins dry?

They were over-baked or had too much flour. Spoon the flour into the cup and level it rather than scooping, and pull the muffins as soon as a toothpick shows moist crumbs.

Can I use butter instead of oil?

Yes, use the same amount of melted and slightly cooled butter. The flavor is richer, but the muffins will be firmer once cooled and dry out a little faster.

Can I make these into chocolate cupcakes?

They are denser and less sweet than cupcakes, but they are delicious frosted. Fill the liners three-quarters full and bake at 350°F the whole time for flat tops.

How do I keep chocolate chips from sinking?

This batter is thick enough to hold them. For thinner batters, toss the chips with a tablespoon of the flour mixture before folding them in, or use mini chips.
