What Are Double Chocolate Muffins?
Simply put, double chocolate muffins are chocolate muffins made with two forms of chocolate. Typically, this means cocoa powder in the batter combined with chocolate chips or chunks folded throughout. As a result, the muffins have a rich chocolate base while also delivering melty pockets of chocolate in every bite.
Unlike basic chocolate muffins, double chocolate muffins are deeper in flavor and noticeably more indulgent. Therefore, they are often described as dessert-style muffins, even though many people enjoy them for breakfast.
Moreover, these muffins are incredibly versatile. For example, they can be made with milk chocolate, dark chocolate, or even white chocolate chips. Additionally, you can adjust the sweetness, richness, or texture depending on your preferences.

Ingredients for Double Chocolate Muffins

Before you begin, it is important to gather all your ingredients. Fortunately, everything used in this recipe is simple and easy to find.
Dry Ingredients
- 1¾ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- ¾ cup granulated sugar
- ¼ cup brown sugar
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
Wet Ingredients
- 2 large eggs (room temperature)
- ¾ cup milk
- ½ cup vegetable oil (or melted butter)
- 2 teaspoons vanilla extract
Chocolate
- 1 cup chocolate chips or chocolate chunks
- Extra chocolate chips for topping (optional but recommended)
Because each ingredient plays an important role, it is best not to skip or substitute unless necessary.
Why Oil Makes These Muffins Extra Moist
Many people wonder why oil is used instead of butter in muffin recipes. While butter adds flavor, oil creates a softer, more tender crumb. Therefore, using oil helps ensure these double chocolate muffins stay moist for days.
Moreover, oil keeps muffins soft even after refrigeration or freezing. As a result, these muffins maintain their texture much longer than butter-based versions.
However, if you prefer butter, you can absolutely use it. Just keep in mind that the muffins may be slightly less moist.
How to Make Double Chocolate Muffins (Step-by-Step)


Making these muffins is very straightforward. Nevertheless, following each step carefully will help you achieve perfect results.
Step 1: Preheat the Oven
First, preheat your oven to 375°F (190°C). Meanwhile, line a muffin pan with paper liners or lightly grease it.
Step 2: Mix the Dry Ingredients
Next, in a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt. At this stage, make sure everything is evenly combined.
Step 3: Add the Wet Ingredients
Then, add the eggs, milk, oil, and vanilla extract to the dry ingredients. Gently mix until just combined. However, be careful not to overmix, as this can lead to dense muffins.
Step 4: Fold in the Chocolate Chips
After that, fold in the chocolate chips using a spatula. Additionally, reserve a few chocolate chips to sprinkle on top.
Step 5: Fill the Muffin Pan
Now, divide the batter evenly between the muffin cups, filling each about ¾ full. As a result, the muffins will rise beautifully without overflowing.
Step 6: Bake
Bake for 18–22 minutes. Meanwhile, your kitchen will fill with an amazing chocolate aroma. The muffins are done when a toothpick inserted into the center comes out with moist crumbs.
Step 7: Cool and Serve
Finally, let the muffins cool in the pan for 5 minutes. Then, transfer them to a wire rack to cool completely.
