Jumbo Chocolate Chunk Muffins

I don’t know if you have ever had a Costco Chocolate Muffin before but they are so delicious and they’re huge! The “secret” ingredient for their muffins is really just cake mix! So much for thinking they were nutritious, huh? I always thought they were too delicious to really be a breakfast food. My kids enjoy these muffins and I will be making more varieties soon! I’m thinking blueberry and cinnamon struesel!

When I made these muffins I filled them almost full. If you want muffins with the huge muffin tops I would suggest to only make about 6 muffins and fill the liners a little more to achieve the muffin top you desire. These muffins came out really well and I think next time I make them I may double my batch and have larger and more muffins! It’s not even 24 hours later and these muffins are gone! They’re that good!

 


When these Jumbo Chocolate Chunk Muffins came out of the oven my house filled with the smell of chocolate. It was so wonderful and my son couldn’t wait to try one. The chocolate chunks melting into the muffin only made the wait even harder for him!

  1. I was explaining to the fella how awesome the chocolate Costco muffins were when you warmed them up and ate them with a glass of milk. This recipe looks like a killer copycat. Love it!

  2. I think these jumbo muffins would be a perfect surprise for my chocoholic hubby, who probably has never seen bigger muffins. In combination with the raspberries they look almost healthy;)

  3. Dana, I love that the recipe doesn’t require a bunch ingredients! I LOVE chocolate. I can not wait to make these and watch them go quickly because the kids have eaten them all.
