Oreo Stuffed M&M Cookie Cake

I made an Oreo Stuffed M&M Cookie Cake this past weekend. This is not a drill.

My inner fat kid is on full display here. I tweaked my M&M Cookie recipe, made it into a cookie cake and stuffed it with Oreos. I don’t know what I was thinking.  That’s a lie. I was thinking, “Damn, I bet that would be amazing.” And it was. This Oreo Stuffed M&M Cookie Cake is 100% indulgence, but it’s worth every calorie.

I would probably eat anything if it was stuffed with Oreos. It’s one of those foods that I rarely have in my pantry, because I simply can’t control myself around them. The only self control that I had when making this was using original Oreos rather than reaching for the Double Stuffed. Maybe next time though…

As insane as this dessert looks, it’s so easy to make. It’s just a giant cookie recipe pressed into an 8×8 baking pan with whole Oreos in the middle. Alternatively, you could crush the Oreos and sprinkle them in.  Both would be delicious, but I think leaving the Oreos whole has a higher oh-my-good-gracious factor. 

Don’t be alarmed when you pick up the pan and it’s roughly the weight of a newborn. I told you this was pure indulgence. 

Happy Sifting!

  • 3 cups flour
  • 1 ½ tsp salt
  • 1 ½ tsp baking soda

Press the remaining half of the dough over top of the Oreos, making sure to cover them completely. Sprinkle a handful of M&Ms on top and lightly press them into the dough for presentation points.
  7. Bake for 20-25 minutes or until the top is golden brown and a knife inserted into the center of the cake comes out clean.
