You need to know, right off the bat, that I feel slightly guilty calling these muffins. If you’ve ever had a Costco chocolate muffin, you know what I mean. They aren’t fooling anybody. Because these so-called “muffins” are actually rich, moist, chocolate cupcakes….without frosting. And of course, there’s the fact that they’re made with a chocolate cake mix. It’s a dead giveaway. But if we call them muffins, we can eat them for breakfast, and I’m good with that.
Costco muffins are enormous, so I elected to make mine in a regular sized muffin tin. I will say–and my family agreed–that these do taste very much like the Costco variety. I like to use mini chocolate chips, but the regular size will work too. Either way, these are some of the tastiest chocolate “muffins” you’ll ever try!
