Fudgy Double Chocolate Muffins Recipe (Ready in 30 Minutes)
These double chocolate muffins are rich, tender, and packed with chocolate chips that melt into gooey pockets.
They come together in one bowl and bake up tall, with crackly tops and a fudgy center that stays soft for days.
What Makes These Double Chocolate Muffins So Good
Cocoa powder and melted dark chocolate give them a deep cocoa backbone, while a generous handful of chocolate chips melts into little fudge puddles as they bake.
A mix of oil and buttermilk keeps the crumb soft without being greasy. I often make a batch on Sunday and they’re still tender in Tuesday’s lunchbox.
Ingredients
- 1 3/4 cups all-purpose flour: spooned and leveled, or weigh 210 g
- 1/2 cup Dutch-process cocoa powder: for deep chocolate flavor
- 1 cup granulated sugar
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp fine sea salt
- 2 large eggs, room temperature
- 1/2 cup neutral oil: vegetable or canola
- 1 cup buttermilk, room temperature: makes them extra tender
- 2 tsp vanilla extract
- 4 oz dark chocolate (60 to 70%), melted and slightly cooled
- 1 cup semisweet chocolate chips, plus extra for tops
Variations / Substitutions
- No buttermilk?: Stir 1 tablespoon lemon juice or white vinegar into 1 cup whole milk and let it sit 5 minutes.
- Oil swap: Melted unsalted butter works for a richer flavor; the muffins will firm up more as they cool.
- Gluten-free: Use a 1:1 gluten-free all-purpose flour blend that contains xanthan gum; the texture will be a touch more tender.
- Add crunch: Fold in 1/2 cup toasted chopped walnuts or pecans with the chocolate chips.
- White chocolate twist: Replace the semisweet chips with white chocolate chips for a sweeter, creamy contrast.

How to Make Fudgy Double Chocolate Muffins
Step 1: Mix the Dry Ingredients
Preheat the oven to 425°F (220°C) and line a 12-cup muffin tin with paper liners. In a large bowl, whisk together the 1 3/4 cups flour, 1/2 cup cocoa powder, 1 cup sugar, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.
The mixture should look uniform and free of lumps. If your cocoa is clumpy, push the dry mix through a fine-mesh strainer for a smooth batter later.
Step 2: Whisk the Wet Ingredients
In a medium bowl, whisk the 2 eggs, 1/2 cup oil, 1 cup buttermilk, 2 teaspoons vanilla, and the 4 oz of melted chocolate until the batter is glossy and thick.
Make sure the melted chocolate is just warm, not hot. If it’s too hot, it can scramble the eggs when they hit the bowl.
Step 3: Fold in the Dry Mix and Chocolate Chips
Pour the dry ingredients into the wet mixture and fold with a rubber spatula until you barely see a few streaks of flour. Then gently fold in the 1 cup of chocolate chips just until they’re distributed.
Stop folding as soon as no flour streaks remain. A few small lumps are fine; overmixing develops gluten and makes the muffins dense instead of tender.
Step 4: Bake the Muffins
Divide the thick batter evenly among the liners, filling them right to the top — this gives you tall domes. Sprinkle the extra chocolate chips over each muffin, then slide the pan into the oven. Bake at 425°F for 5 minutes, then without opening the door reduce the temperature to 350°F (175°C) and bake another 13 to 15 minutes, until a toothpick inserted in the center comes out with moist crumbs.
The initial blast of high heat forces the muffins up fast, creating that bakery-style dome. The tops will be set and crackly.
Step 5: Unmold and Serve
Let the muffins cool in the pan for 5 minutes so the structure sets, then lift them out and set them on a wire rack. Serve while they’re still warm — the crust will be slightly crisp and the inside fudgy with pockets of molten chocolate.
Tips for Tall, Fudgy Muffins
- Use room-temperature eggs and buttermilk. Cold ingredients don’t blend as smoothly and can weigh the batter down.
- An ice cream scoop divides the thick batter evenly and keeps your hands clean. One heaping scoop per liner is about right.
- Fold by hand, not with a mixer. Even a few extra stirs can toughen the crumb.
- For extra-crackly tops, sprinkle turbinado or demerara sugar over the batter just before baking.
Keeping Them Fresh
Room temperature: Store muffins in an airtight container at room temperature for up to 3 days. They stay moist thanks to the oil and buttermilk. Freeze: Wrap each muffin in plastic wrap and place in a zip-top bag. Freeze up to 2 months. Thaw overnight at room temperature or microwave for 30 seconds for a warm treat.
Frequently Asked Questions
Why didn’t my muffins rise tall?
If your muffins spread instead of domed, the batter was likely overmixed or the oven temperature ran low. Start at a true 425°F for the full 5 minutes to give them that initial spring.
Why are my muffins dry?
Dry muffins usually come from too much flour or overbaking. Spoon flour into the cup and level it, or better yet, use a scale. Check for doneness a minute or two early and look for moist crumbs on the toothpick.
Can I use natural cocoa powder instead of Dutch-process?
Yes, natural cocoa works, but the muffins will be lighter in color and less fudgy. Natural cocoa is also more acidic, so the batter may react slightly differently — the result is still good, just not as dark and rich.
