Costco

The real Costco muffins taste great, but they may not be as wholesome as you would like them to be. The dough has been conditioned with gums to thicken, ingredients to emulsify, and to preserve shelf-life the muffins contain no butter. Plus, the flavors you taste—including butter, almond, and vanilla—are all artificial.

I attempted to stay true to the original formula in my first take on the famous muffins with this copycat recipe for Costco’s Blueberry Muffins. In that hack, I chose to avoid butter like the real muffins do, opting instead for margarine. And since the Costco muffins contain no buttermilk, I also stayed away from that ingredient, even though I love its magical properties for baking.

This time, for my Costco Almond Poppy Muffins recipe, I’m taking a different approach to hacking the muffins with more whole egg, real butter, and, yes, buttermilk to bring great flavor and a better crumb to our finished product. Without all the dough conditioners found in the original, these home-cloned muffins are less rubbery and slightly crumblier than Costco’s, and the flavor is better, because it’s real.

Three things make Costco Blueberry Muffins special: they’re huge, they’re moist, and berries are bursting out of the top of each one. Now your home muffins can be just as special using a similar recipe and freshly unlocked tricks from our favorite big-box store.

Obviously, you get huge muffins by using a huge muffin pan, so you’ll need a jumbo or “Texas-size” muffin pan if you want your muffins the same size as the originals. You can certainly make standard muffins with this batter in a standard-size muffin pan, but in this case, bigger is definitely better.

To get muffins that are moist like Kirkland's, you’ll need oil. I noticed many muffin recipes use butter, but I found it made the muffins taste more like butter cake or pound cake than true muffins. Looking at the ingredients listed on the package of Kirkland muffins, you won’t find any butter in there. Just oil. For my Costco Blueberry Muffin copycat recipe, some of that oil comes from margarine (for a mild butter flavor and thicker batter), and the rest is vegetable oil.

As for the blueberries, if you add them straight into the batter the juice frozen on the outside of the berries will streak your batter blue, so be sure to rinse the berries before you add them. And to make your muffins look as irresistible as those at Costco, we’ll use another one of their tasty tricks: press 4 blueberries into the batter in each cup just before the pan goes into the oven so that every baked muffin is sure to have several tantalizing berries popping out of the top.
