M&M cookie bars

February 17, 2016

These M&M blondie cookie bars are filled with chocolatey M&Ms. They are like having brownies but with a vanilla flavor profile as a base instead.

Instead of making them like cookies where you would drop the dough by the spoonful, all you need to do is spread the batter onto a baking pan and you’re good to go!


The thing about this recipe is that you need to follow every single step to the T otherwise they won’t turn out the way they’re intended to.

Trust me, I’ve tried.


On the note of not following the recipe properly, “back in the day” when I took Food Studies in high school, I would barely ever read my recipe the whole way through before carrying it out.

That’s what happens when you’re a real go-getter and have a passion for food so you can’t blame me for doing so.


Most of the time I would get into trouble for it because “it’s essential to read all the instructions first otherwise it won’t turn out properly.”

And after a while, my teacher finally got to me and I started following the recipe again since things weren’t tasting too stellar so I figured I should make the change.


For the most part sticking to the recipe made all the difference but there was this one instance where we were making bar cookies and even after 35 mins in the oven, ours wouldn’t set.

So what did I do? I shook them and banged my baking pan on the table. My teacher came over asking what I was doing and I told her “I’m checking to make sure it’s ready.” She then told me to put them back in the oven and let them be.

I’m not sure if I learned anything from that instance though because to be honest, shaking our baking pan actually made our bars turn out chewier and fudgier than our friend’s batch….which made them all the more delicious.


Have any of your baking “mishaps” turn into winners?

Have a great week,
