This decadent double chocolate muffin recipe transforms ordinary mornings into special occasions with its rich cocoa flavor and melty chocolate chunks. The brown sugar adds moisture while the sour cream creates a tender crumb that stays fresh for days.
I created these muffins during a rainy weekend when my chocolate cravings hit hard. After several test batches playing with different ratios of cocoa to chocolate chunks, this version consistently disappears fastest when I bring them to family gatherings.
Ingredients
- All purpose flour: Provides the perfect structure without becoming too dense
- Brown sugar: Adds moisture and a subtle caramel undertone that enhances the chocolate
- Granulated sugar: Balances the sweetness and helps create that beautiful domed top
- Unsweetened cocoa powder: Is the foundation of the chocolate flavor; sift it to avoid lumps
- Baking powder and baking soda: Work together for the perfect rise and tender texture
- Sea salt: Enhances all the flavors especially the chocolate; use fine salt for even distribution
- Melted butter: Adds richness and flavor; use unsalted to control the salt level
- Sour cream: Provides moisture and tanginess that makes these muffins extra tender
- Whole milk: Adds necessary liquid while the fat content contributes to a richer muffin
- Large eggs: Bind everything together and add structure
- Vanilla extract: Enhances the chocolate flavor significantly
- Semisweet chocolate chunks: Create pockets of melty goodness throughout each bite
Step-by-Step Instructions
- Prepare Your Equipment:
- Heat your oven to 375°F exactly. Too hot and the muffins will peak too quickly and crack. Too cool and they won't develop that beautiful dome. Line your muffin tin with paper liners to prevent sticking and make cleanup easier.
- Mix Dry Ingredients:
- Whisk together flour, both sugars, cocoa powder, baking powder, baking soda, and salt in a large bowl. This thorough mixing ensures even distribution of the leavening agents and prevents bitter pockets of baking soda or powder. Take your time with this step for consistently flavored muffins.
- Combine Wet Ingredients:
- In a separate bowl, mix melted butter that has cooled slightly, sour cream, milk, eggs, and vanilla until completely smooth. The melted butter should be warm but not hot to avoid cooking the eggs. This wet mixture should be uniform in color with no streaks of egg visible.
- Create The Batter:
- Pour the wet ingredients into the dry ingredients all at once and stir just until the flour disappears. The batter will be quite thick which is exactly what you want. Avoid the temptation to keep mixing as this develops gluten and results in tough muffins. Gently fold in the chocolate chunks saving a few to press into the tops if desired.
- Fill And Bake:
- Use a cookie scoop or large spoon to divide the batter evenly among muffin cups filling them about three quarters full. Bake for exactly 20 minutes or until a toothpick inserted comes out with a few moist crumbs but no wet batter. Allow to cool in the pan for 5 minutes before transferring to a wire rack.

The chocolate chunks are truly the star ingredient in this recipe. I discovered that using chunks rather than chips creates magical pockets of melted chocolate that stay gooey even after cooling. My daughter calls these "chocolate treasure muffins" because finding those melty chocolate pieces feels like discovering hidden gems.
Storage Tips
These muffins stay fresh at room temperature in an airtight container for up to 3 days. The flavor actually improves on the second day as the chocolate notes deepen. For longer storage, freeze completely cooled muffins individually wrapped in plastic then placed in a freezer bag. Thaw overnight at room temperature or microwave for 20 seconds for a fresh from the oven taste.
Ingredient Variations
You can customize these muffins to suit your preferences or pantry. Greek yogurt works perfectly in place of sour cream with no noticeable difference. For a dairy free version, substitute plant based milk, vegan butter, and dairy free yogurt. Add a tablespoon of instant espresso powder to intensify the chocolate flavor without adding coffee taste. Mix in half a cup of toasted nuts or dried cherries for interesting texture and flavor combinations.
Serving Suggestions
These muffins are wonderful on their own but turn truly decadent when split and warmed for 10 seconds in the microwave. Serve them with fresh berries and whipped cream for an elegant dessert, or alongside a glass of cold milk for an afterschool treat. For special occasions, drizzle slightly warm muffins with a simple ganache made from equal parts heavy cream and chocolate for an extra special touch.
