White Chocolate M&M Cookie Bars

White Chocolate M&M Cookie Bars

At my work Christmas party we do a gift exchange.  It’s always a hoot and by far the best part of the party.  But each year I struggle with what to buy. I want it to be perfect and highly “steal-able”.  (It’s one of those gift exchanges.)  The booze and the coffee are always big hits with my drunk co-workers…

This year I did a “Dessert of the Month Club” gift.  It entitled the winner to receive a homemade dessert each month for 3 months.  That’s cool, right?  Well, this was this months dessert for the winner – White Chocolate M&M Cookie Bars.  YUM!

As if it couldn’t get any better than just this.

Then we added sweetened condensed milk.  Heaven!

When the edges are brown and the top is bubbly and gooey looking, it’s done.  Don’t worry about it looking too gooey.  It’ll be great once it cools.  (And P.S., can anything be too gooey???)

Allow to cool before you gently lift them out of the pan and onto a cutting board.  I’m warning you – they are gooey and sticky and amazing but make sure you spray your parchment paper and your pan with non-stick cooking spray!

The edges are my favorite.  The are a little crunchy and a lot gooey and even more amazing.

We made two batches of these bars.  The original white chocolate recipe and then one batch with milk chocolate chips instead of white chocolate chips.  They were delicious as well.  How could they not be???!!!

The milk chocolate might have been my favorite.

I think if you’re going for a Valentine look, the white chocolate chips were perfect.
