These double chocolate chunk muffins are a pretty spot on copy cat of the Kirkland chocolate muffins from Costco. These muffins are ultra rich, chocolatey, and the perfect way for anyone with a sweet tooth to start the day!

I love Costco.

Its selection of ready made bakery items just can’t be beat.

One of my favorites? The chocolate chunk muffins.

They are decadent and rich, studded with chocolate chips.

The one thing I don’t love about Costco?

It’s always crowded.

And when I want those double chocolate chunk muffins without having to battle the crowds, now I can have my ~~cake~~ muffins and eat em too!
