Double Chocolate Chip Muffins
Rich, fudgy muffins loaded with chocolate in two forms: cocoa powder mixed into the batter for deep chocolate flavor, and chocolate chips throughout for pockets of melted chocolate. These are tender, moist, and perfect for breakfast or a snack.
Steps
Before you start
- Preheat oven to 375°F (190°C)
- Line a 12-cup muffin tin with paper liners or grease it well
- Bring eggs to room temperature for better mixing
- Have all ingredients measured and ready before you start
Mix dry ingredients
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
- Set aside.

Ready when: Cocoa powder is evenly distributed with no lumps
Tip: Sift the cocoa powder first if it's lumpy, or whisk vigorously to break up clumps
Cream butter and sugar
- In a large bowl, beat the softened butter and granulated sugar together with a wooden spoon or hand mixer for 2–3 minutes until light, pale, and fluffy.
- Scrape down the bowl frequently.

Ready when: Mixture is noticeably lighter in color and fluffy
Tip: This step aerates the batter, making the muffins tender; don't skip it
Add eggs and vanilla
- Add the room-temperature eggs one at a time, beating well after each addition until fully incorporated.
- Pour in the vanilla extract and mix until smooth.

Ready when: Mixture is smooth and homogeneous with no streaks of egg
Tip: Room-temperature eggs blend in more smoothly and prevent the batter from looking curdled
Combine wet and dry
- Alternate adding the dry ingredient mixture and sour cream to the butter mixture, starting and ending with the dry ingredients.
- Add one-third of the dry mix, fold gently with a rubber spatula until almost combined, then add half the sour cream and fold until just combined.
- Repeat with another third of dry, the remaining sour cream, and finish with the last third of dry ingredients.
- Stop folding as soon as no flour streaks remain.

Ready when: No white flour streaks visible; batter is thick and lumpy rather than smooth
Tip: Overmixing develops gluten and makes muffins tough; a few lumps are fine and desirable
Fold in chocolate
- Gently fold the semi-sweet or dark chocolate chips (and milk chocolate chips if using) into the batter with a rubber spatula until evenly distributed, using only 3–4 folds.

Ready when: Chocolate chips are distributed throughout with no dry batter visible
Tip: Don't overmix; fold just until the chips are evenly scattered
Fill muffin cups
- Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
- Use an ice cream scoop or ¼-cup measure for consistency.
- If using paper liners, fill those; if greasing the tin, place a small amount of batter in each cup first to prevent sticking.

Ready when: All 12 cups filled evenly
Tip: Consistent fill levels ensure even baking and similarly sized muffins
Bake muffinsOven 375°F / 190°C
- Place the muffin tin in the preheated 375°F (190°C) oven.
- Bake for 20–22 minutes, until a wooden toothpick inserted in the center of a muffin comes out with a few moist chocolate crumbs (not wet batter, but not completely clean either).
- The tops should be slightly domed and spring back when lightly pressed.

Ready when: Toothpick comes out with moist crumbs, tops spring back when pressed, and they smell chocolatey and fragrant
Tip: Don't overbake; muffins continue cooking slightly as they cool. A few moist crumbs indicate perfect doneness
Cool in tin
- Remove the muffin tin from the oven and let the muffins rest in the tin for 10 minutes.
- This allows them to firm up so they release cleanly without breaking apart.

Ready when: Muffins have pulled away slightly from the sides of the cups
Tip: Trying to remove them immediately will cause them to crumble; patience pays off here
Remove and cool
- Turn the muffins out onto a wire rack to cool completely, or serve warm.
- They taste delicious either way.

Ready when: Muffins are released from the tin
Tip: For the fluffiest crumb, let them cool to room temperature before eating, though warm is irresistible
Good to know
Tips
- Room-temperature ingredients (especially butter, eggs, and sour cream) mix smoothly and create a more tender crumb than cold ingredients
- Don't skip the 3-minute creaming step; it aerates the batter and makes the muffins light and fluffy
- Fold the dry ingredients in three additions with sour cream in between to prevent overmixing, which toughens muffins
- For extra-fudgy centers, slightly underbake and let residual heat finish cooking as they cool
Make ahead
Muffin batter can be prepared up to 2 hours ahead and refrigerated in an airtight container; bake just before serving. Baked muffins can be made 1 day ahead and stored at room temperature.
Storage & reheating
Room temperature: Keep in an airtight container or wrapped loosely for up to 3 days. Refrigerator: Up to 5 days in an airtight container. Freezer: Wrap individual muffins in plastic wrap and foil; freeze for up to 3 months. Thaw at room temperature or reheat gently in a 300°F (150°C) oven for 8–10 minutes until warmed through.
Substitutions
- sour cream → Greek yogurt or full-fat plain yogurt. Use the same amount; the crumb will be slightly denser but still moist and tender
- semi-sweet or dark chocolate chips → Chopped dark chocolate or chocolate chunks. Use the same weight; larger chunks give a more indulgent texture
- granulated sugar → Brown sugar (packed). Use the same amount; muffins will be slightly more moist and have a deeper flavor
- all-purpose flour → Whole wheat flour or whole wheat pastry flour. Use the same amount for a nuttier flavor, though crumb will be slightly denser; add 2 tsp extra liquid if batter looks dry
