M&M Studded Fudgy Oreo- Chunk Brownies

You’ve gotta love seasonally themed- M&M’s. They can make anything festive. My favorite Oreo-Chunk Brownies are good enough on their own, but the addition of M&M’s gives them a little Halloween Pizzazz.

These brownies are baked on a foil-lined rimmed baking sheet (12 x 18-inches). After an overnight chill, the foil aides in lifting the entire giant brownie out of the pan. The foil is then peeled away and the brownies are firm enough to make nice, clean cuts.

One giant baking sheet turns out a TON of brownies, so be prepared to share. I sent a bunch to school today for Teacher Treat Day and put another bunch of them in the freezer for an upcoming boys’ camping trip.

You may not ever wish to have a boxed brownie again after you try these. They’re really quite easy to make, but you do need to have a secret ingredient (instant espresso powder). It’s really a must. The espresso brings out the flavor of the chocolate in a wonderful way. Sometimes espresso powder is tough to find… but you might have luck at your local market- do ask since they tend to tuck it away in places you wouldn’t think to look for it. I think mine was actually in the ‘international’ aisle.

The oreos are a really nice addition to a fudgy brownie… a tiny bit of crunch to break up the monotony of decadent bite after decadent bite. The orange-filled Halloween oreos would be even better. I’m pretty sure they’re exclusively found at Target this time of year but apparently I was late to the party… they were already sold out.

You’ll want to have a gallon or two of milk nearby. These are some good brownies, but a little goes a long way. And with that added espresso powder you’ll be ready to clean the garage, go rock climbing and hit the gym before you come home to make dinner.

And don’t forget to eat those leftover M&M’s for dessert- they might just give you a little pizzazz too.

This recipe can be found HERE.

    Oh, I think that’s exactly what I need– brownies that go a long way! Somehow I can’t stop putting them in my mouth! (Although I’ve a feeling I’ll still do that with these yummies :)

    Great Halloween treat all kids will love. I think I will make these for my son’s class. (I may eat them before they reach the school though!).

    Oh My! These brownies do look so fudgie good and with oreo to boot! Those are some lucky teachers to get some of these! I do like espresso powder in my chocolate baked goods, you are right it does intensify the chocolate taste. Great pictures! Oh one of my students made your Halloween cake pops for the bake sale we are having today!

    Your brownie edges are so straight! I wish I had the patience to wait for them to chill before I cut into them.

    Thank you for sharing your recipe. I like that this one makes such a large amount. I enjoy bringing treats to my boys’ teams and the parents generally want a piece or two as well! :-)
