M&M Chocolate Cookie Cake Bars Recipe (1)

What's a cookie cake bar? It's a cake that you can hold in your hand and eat and it's a little cookie-like but more moist and softer like a cake. I'm terrible at describing this. Let's just say you'll love it, okay? I know you will!

Instead of yellow cake mix, I used devil's food cake mix and used mini M&Ms that I bought recently. It has a nice balance of chocolate and as Curtis' co-workers said not too overly sweet. And I would say, if you like a more cake-like brownie, I think you'll like this recipe.

This recipe is super easy – I know some will say it's not homemade but it was made with my hands even if it's not from scratch. Just dump all of the ingredients into the bowl except for the M&Ms and mix but don't overmix. Then, slowly fold in the M&Ms and you're almost done!

Dump it into your greased or foiled & greased 9×13 pan and using an angled spatula that's also greased, spread the batter mixture and smooth off the top.

    I can’t make stuff like this…I mean, I can, but I can’t keep stuff like this. I become brain dead when chocolate is anywhere nearby and before I know it I’ve eaten 14 brownies and my heart suddenly starts working overtime because my blood is now chocolate. True story.

    I love the portability of this! Although having a huge cake wouldn’t stop me from its portability – sad I know. I’m seeing some food blogger friends tomorrow so maybe I’ll surprise them with this amazingness!
