These Double Chocolate Muffins are so moist (thanks to buttermilk, canola oil, and applesauce) and loaded with chocolate flavor. Make them with whole wheat flour for extra fiber. The perfect sweet treat or lunch box snack, you’ll love this Carnival copycat recipe!

Super Moist Double Chocolate Muffins
It’s not often that I experiment with muffin recipes. I have a few favorites that I make over and over (and over and over), like these Banana Chocolate Chip Muffins and these Double Chocolate Banana Bran Muffins.
But on a Carnival cruise last December, I became obsessed with the moist and perfectly sweet chocolate muffins at the breakfast buffet. I ate my fair share every morning and even snuck a few back to my room for snacks 🤫.
Reasonably healthy, these double chocolate muffins are packed with unsweetened applesauce and buttermilk for moisture, and whole-wheat flour for protein and fiber. And, of course, just enough chocolate chips to make them a treat!
They don’t puff up big and tall like some bakery muffins, but the texture is so much better! I hope you enjoy them as much as we have!
How many calories are these muffins?
These double chocolate muffins are quite large, yet only 214 calories each! If you want a smaller muffin, you can likely get away with making 14 for only 184 calories each.

Ingredients for Double Chocolate Muffins
- Cooking oil: I use canola oil, but any neutral-flavored oil will work.
- Brown sugar: Light or dark brown sugar both work great here.
- Applesauce: Make sure to grab the unsweetened kind.
- Buttermilk: If you don’t have any, you can make your own by adding a teaspoon of lemon juice or white vinegar to regular milk!
- Flour: Whole wheat flour is what I used for this recipe.
- Cocoa powder: You’ll need the unsweetened kind for baking.
- Mini chocolate chips: I like using mini ones, but regular-sized chocolate chips are fine too!

Tips for the Perfect Double Chocolate Muffins
- Let the muffins cool in the pan for a few minutes before moving them to a wire rack. This helps them firm up so they don’t fall apart.
- Want a richer chocolate flavor? “Bloom” your cocoa powder by whisking it with a bit of hot water or coffee before adding it to the mix.
- To prevent the chocolate chips from sinking to the bottom of the muffins, toss them in a tablespoon of flour before folding them into the batter.
- Be careful not to overmix! Once you add the dry ingredients, stir just until you no longer see any streaks of flour. This will give you the softest, most tender muffins.

How to Store
You can store your muffins in an airtight container at room temperature for up to 3 days. If you want them to last longer, you can store them in the refrigerator for up to a week.
To reheat, I like to just microwave them for about 30 seconds. Easy!

Can I use all purpose flour instead? If yes, would it still be 1 cup?
