Copycat Costco Chocolate Muffins taste just like the amazing double chocolate muffins from Costco. Easy chocolate chocolate chip muffin recipe that everyone loves!
We all know that muffins are pretty much just cake, but somehow when you call them muffins, it becomes more acceptable to eat for breakfast instead of having to wait for dessert, right?! These muffins are definitely a favorite around here, because they really do taste very much like chocolate cake and are absolutely incredible. Might have something to do with the fact that you actually use a cake mix in the batter!
What are Copycat Costco Chocolate Muffins?
We love getting muffins at Costco, and the chocolate ones are among our favorites. They are soft, moist and loaded with chocolate chips…double chocolate is always a good idea! This recipe uses chocolate pudding and a cake mix, so they are super easy to make, but really do end up tasting like they came straight from the bakery at Costco.
What to serve with Double Chocolate Muffins?
We love to eat these chocolate muffins for breakfast, but they make a perfect snack or dessert too! Many times I make mini muffins for my kids so that they can just eat one or two along with some eggs and fruit and it’s not quite as much sugar to start off the day as eating a full size muffin. It’s a fun way to give breakfast a little more exciting sometimes!
Ingredients in Copycat Costco Chocolate Muffins
Eggs – 3 eggs might sound like a lot for a muffin recipe, but this recipe makes a lot of muffins!
Milk – You can use any kind of milk. We always use 1% because that’s what we keep in the fridge, but you can use almond milk, 2%, whole milk, skim milk…it all works just fine!
Oil – You can use vegetable or canola oil for the muffins. I like to use coconut oil in baked goods and it works beautifully in this recipe.
Water – Just adds a little bit of extra moisture for the muffin recipe.
Vanilla extract – Just a little bit of vanilla adds that extra richness and flavor to the batter.
Sour Cream: Adding 3/4 cup of sour cream into the batter will thicken it up but help the muffins to turn out light and fluffy. You can swap this out with plain or vanilla Greek yogurt.
Devils Food cake mix – Any chocolate cake mix will work fine, but we like to use the Devil’s Food cake variety.
Chocolate pudding mix -Just a small box of instant chocolate pudding mix adds a lot of moistness and chocolate flavor!
Cinnamon – Seems a little weird to add cinnamon to chocolate, but I promise it’s good! You can leave it out if you prefer, but I really like it in there. It’s very subtle in the muffins – you may not even really notice it!
Semi-sweet chocolate chips – You’ll need 2 cups of semi-sweet chocolate chips for this recipe. Most of them get mixed right into the muffins, but you’ll save some to sprinkle on top as well. Makes the muffins look like they came straight from the bakery!

Can you make mini muffins?
Absolutely! If you want to make mini muffins, this recipe will make about 48 of them. Just scoop into mini muffin tins lined with liners and then bake for about 12-15 minutes or just until a toothpick inserted in the center comes out clean.
CAN YOU FREEZE DOUBLE CHOCOLATE MUFFINS?
Yes, these muffins can be frozen. Simply place them in an airtight container and freeze for up to 3 months. Thaw before eating by placing a muffin (or more) on the counter for about 30 minutes to come to room temperature.
WHAT CAN I USE AS A SUBSTITUTE FOR SOUR CREAM?
I almost always swap out the sour cream with Greek yogurt when baking. Plain Greek yogurt is the closest to sour cream, but I usually have vanilla Greek yogurt on hand so I like to use that because it does add a little more flavor and sweetness as well. You shouldn’t try to use regular yogurts though as those have a much higher sugar and water content that will throw off the wet: dry ratio in this recipe.

Lisalia says
All the flavor of those yummy Costco chocolate muffins – without that HUGE serving size… my kids usually have a couple bites then throw the rest away. Next time I’m going to try your recipe in mini-muffin liners… I think that would be absolutely perfect for my little ones! Thanks for such a yummy recipe!
Marsha says
My absolute favourite chocolate muffins. SO GOOD!
Mayra says
They are good but they are very fluffy and not as dense of the ones from Costco.
Kathy says
Mayra it is the sour cream that makes it fluffy leaving out the sour cream and its dense when I make a chocolate cake I like a dense rich moist cake and I add warm water instead of cold it brings out the cocoa flavor and I add a stick of butter in addition to the oil that the cake box instructs and 3.5 oz choc instant pudding I also discovered if you put the the chips in the food processor and chop them into small pieces when the cake bakes they melt making your cake rich and full of flavor. Then I refrigerate the cake or muffins overnight and oh so good ! I usually go with a choc butter cream frosting. Just a couple tips I learned over time I also discovered if you put a small can of water next to the pans of cake you are baking there will not be any dome or dried crusty edges your cake bakes evenly and no cake to waste.
Andrea Holmes says
Could the recipe be turned into a 9×13 cake? How long to bake?

Is there any substitute for instant pudding mix, as it’s not available in our region
Jessica says
Absolutely. Instead, I’d put in 1 TBSP cornstarch + 1 TBSP cocoa powder + 3 TBSP sugar. : )
