Ingredient Notes

Four images show the process of making chocolate cookie dough: ingredients arranged on a counter, dough forming in a bowl, chocolate chips being added, and the final mixed dough with a spatula.

Butter:Melts down to give the muffins a rich, unmistakable bakery flavor and velvety texture.

Dutch-Processed Unsweetened Cocoa Powder:This cocoa is treated to reduce acidity, resulting in an incredibly dark color and a smoother, deeper chocolate flavor in your muffins.

Granulated Sugar:Balances out the robust, bitter edge to the chocolate powder.

Baking Powder:The leavening agent responsible for giving the muffins those beautiful, high-domed tops.

Salt:Standard baking essential that rounds out the flavor.

Pure Vanilla Extract:Adds additional aromatic flavor to the chocolate.

Eggs:Provide the liquid structure to the muffins.

Milk:When combined with eggs, provides the liquid structure to the muffins and binds the batter together.

Sour Cream:This is the secret weapon to the best chocolate muffins. The acidity softens the gluten bonds, ensuring a tender crumb that stays moist for days.

Whole-Wheat Flour:Used in the flour blend to provide a structurally sound muffin.

All-Purpose Flour:Combined with whole-wheat flour to provide the structure for the muffins.

Chocolate Chips:Semi-sweet or milk chocolate chips give the muffins a sweet bite.

Coarse Sugar:Sprinkled on top right before baking to give them a professional bakery finish.

How to Make Double Chocolate Muffins

A muffin tin with twelve cups, each filled with chocolate muffin batter and topped with chocolate chips, sits on a light-colored countertop.

Preheat the oven to 350°F. Grease a 12-cup muffin tin or line it with paper liners.
In a large mixing bowl, beat together the butter, cocoa powder, sugar, baking powder, salt, and vanilla until well combined and fluffy.
Add the eggs and mix until smooth.
Stir in the milk and sour cream until fully combined.
Add both flours and mix just until incorporated.
Fold in the chocolate chips.
Divide the batter evenly between the muffin cups. The cups will be quite full.
Sprinkle the tops with coarse sugar if desired.
Bake for 25–30 minutes, or until a toothpick inserted into the center comes out mostly clean. Melted chocolate on the toothpick is fine.
Let the muffins cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.

Frequently Asked Questions

Why are my muffins dry?

Muffins can turn out dry if there isn’t enough fat or if they are baked too long. Ensure you use the full amount of butter and sour cream, and start checking them with a toothpick a couple of minutes before the timer goes off.

What is the difference between regular cocoa powder and Dutch-processed cocoa powder?

Dutch-processed cocoa powder has been neutralized, making it darker, more mellow, and less bitter than natural cocoa powder.

Can I use whole-wheat flour only?

Yes, you can use only whole-wheat flour; however, it will make the muffin dense and not as cake-like as the mixture of whole-wheat and all-purpose.

Can I make these into cupcakes?

While these are rich and decadent, muffin batter has a denser crumb than cake batter. If you do want to turn them into cupcakes, add a little bit of chocolate or cream cheese frosting on top.
