I didn't really think these tasted much like Costco muffins...they were a little more cupcake-y than costco's are...I might try them with a touch more oil to try to get closer. BUT I am definitely going to keep this recipe around for the fact that it's EASY and VERSATILE!

My kids really liked these. I added 2 tsp. of vanilla and milk chocolate chips to the batter. Everyone said they tasted more like a cupcake than a muffin. Thanks for an easy recipe.

The muffins came out good, but they didn't taste anything like Costco muffins to me. I used a Duncan Heinz Spice Cake mix, and cut up an apple to put in the batter, to simulate Costco's apple-cinnamon muffins. Not even close. Definitely not the best cupcake I've made either, but not bad. I think without the apples, it would have been really dry.
