Ingredients

Why this recipe works

The method starts by melting dark and milk chocolate with butter, creating a rich, smooth base that gives these muffins their intense chocolate flavor.

Whisking the eggs and sugar until pale and ribbony incorporates air, which helps the muffin tops rise and form that beautiful crackly crust. The combination of melted chocolate and whipped eggs ensures a fudgy, moist texture that stays soft even after cooling.

Folding the dry ingredients gently and adding chocolate chunks before baking creates pockets of molten chocolate in the center.

The high ratio of chocolate to flour keeps the batter thick and fudgy, while the short baking time at 350°F (175°C) allows the tops to set without overcooking the centers. The result is a muffin that's crisp on the outside, tender on the inside, and full of gooey chocolate in every bite.

Notes and substitutions

Use good-quality dark and milk chocolate for the best flavor. The dark chocolate provides depth, while the milk chocolate adds creaminess. If you prefer a more intense chocolate taste, use all dark chocolate. The butter should be unsalted to control the salt level. For the chocolate chunks, dark chocolate chunks work well, but you can also use a chopped chocolate bar or chocolate chips.

The eggs and sugar need to be whisked until thick and pale, which takes about 2-3 minutes with an electric whisk. This step is crucial for the crackly top. When folding the dry ingredients, be careful not to overmix, as that can make the muffins tough. The batter will be thick and glossy, similar to a brownie batter. Use paper liners for easy removal and to keep the muffins moist.
