Growing up, if there was a chocolate chip muffin as an option, it was my first choice. But as adults, we typically think of a chocolate chip muffin as boring. Enter these chocolate chunk muffins!

When you choose to make this muffin, you’re choosing anything but boring! They’re full of chocolate chunks and a soft and buttery texture. The profile of the chocolate can be customized with darker chocolate for more intensity or lighter chocolate for more sweetness.

To amp up the texture and give these a bakery-style finish, the muffins are sprinkled with turbinado sugar. During baking, the sugar maintains texture and creates a beautiful crackly crust.

The ingredients in these chocolate chunk muffins

  • Sugar is aerated with butter to achieve a light and airy texture. The amount of sugar is reduced slightly from other muffin recipes to achieve a muffin that’s not too sweet, which allows the chocolate to really shine through.
  • Butter adds flavor and moisture to the muffin. Use an unsalted butter to control the overall salt level of the recipe.
  • Sour cream lends a rich density to the muffins while retaining a light texture.
  • Vanilla extract amplifies the chocolate and also gives the batter a light flavor, complementing the chocolate.
  • Chocolate is what will cause someone choose this muffin over others. Make sure to choose a good quality chocolate as that really does impact the resulting flavor. Any chocolate from milk to bittersweet will work, depending on the intensity you desire.

Tips regarding chocolate

Chocolate chunks are what make this muffin stand out against other muffins that only use only chocolate chips. Chocolate chips have added stabilizers that help them hold their shape even after baking. That’s why I always recommend using chocolate bars.

Cutting up bars of chocolate will provide thick, rich ribbons of chocolate throughout the muffin with even more flavor. Trust me: cut the chocolate into large irregular pieces and the result will make you wonder why you ever used chips.

    Wonderful recipe! Very fluffy and moist. My 11 year old son (not a big sweets eater) was so sad when they were gone. Making another batch tonight!
