Double Chocolate Muffins
This Double Chocolate Muffin Recipe makes the fudgiest breakfast for chocolate lovers. A copycat of Costco double chocolate muffins with whole wheat flour and chocolate chips.

Eating chocolate muffins for breakfast feels a little decadent, but baking them with whole wheat flour makes me feel a little better about treating my family to these Whole Wheat Chocolate Chip Muffins.
❤️ Why You’ll Love This Recipe: These big, fluffy, rich double chocolate muffins are always a crowd-pleaser for breakfast or brunch. They have a soft, tender texture and plenty of chocolate chips throughout.
Update: We’ve been making these double chocolate muffins for years. They’re a favorite of my husband, so I’ve updated this post with new tips and photos!
How to Make Double Chocolate Muffins
This recipe is adapted from King Arthur Flour’s Golden Chocolate Chip Muffins Recipe.
Before you get started, all of the ingredients should be at room temperature so they blend properly. This way, the muffins will bake to be big beautiful bakery style muffins.
As with any muffin, only mix the batter until it’s just combined. It should not be over-mixed, and leaving a few lumps in the batter is totally fine.
Then, gently fold the chocolate chips into the batter.
This batter is thick! I use a cookie scoop to fill the muffin cups. You’ll fill the muffins cups right up to the top.
Ingredient Notes
Look for whole wheat flour in the same aisle where you find your traditional all-purpose flour.
This is the King Arthur cocoa I prefer to use. It works for all types of recipes, Dutch-process as well as regular cocoa. It includes black cocoa for a dark rich color.
Decorating Ideas
My husband prefers the chocolate muffins with coarse sugar on top. If you like some extra crunch, go ahead and add a sprinkle before baking.
Looks-wise, it’s hard to be certain that chocolate chips will be on the surface of your muffin when you scoop the batter into the muffin cups. For a little garnish, you can sprinkle a few chips onto the surface of each muffin before you bake them.
Storage Suggestions
Store leftover muffins in an airtight container at room temperature for up to four days. For longer storage, keep the muffins in the freezer for up to six months. Defrost on the counter for a few hours to serve.

They look so decadent chocolately that yes, knowing they are made with whole wheat flour does sort of help me convince myself that they are in fact healthy. Which is why I would do the sugar on top! 🙂
