This funfetti oreo brownie cake is very RICH, fudgy and dense.

The stuffed hidden Oreos in each bite are such a fun SURPRISE.

Make two or three batches of these brownies and arrange them into a LAYER cake.

That cake would be great for kids birthday parties or even adults birthday parties.

Here are some TIPS for making this perfect fudgy funfetti oreo brownie cake:

  • Use SALTED butter instead of unsalted butter since that helps to cut the sweetness from the Oreos.
  • Use a little bit of espresso powder because it ENHANCES the chocolate flavor and also helps to cut the sweetness.
  • Most importantly, if you want to make fudgy brownies, it is best to UNDER-BAKE rather than over-bake. The brownies are ready when a toothpick is inserted into the center and comes out with some wet crumbs. It should not come out dripping with brownie batter…lol.
  • Use a plastic knife for making clean cuts and slices.
  • Only frost this brownie cake with whipped cream, once it has fully COOLED down or else it will melt and result in a huge mess.

  1. This recipe sounds so amazing and I can’t wait to try it out. However there’s a hitch.
    Where I stay, brown sugar is super expensive and quite hard to get so is there any way I can use white sugar instead?
    I’ve read of molasses being a common substitute but that too is unavailable here.

    • I have not tried it with just granulated sugar so I can’t guarantee your results. I personally think that brown sugar adds more flavor and moisture to brownies, making them more “ooey gooey.” If you try this recipe, using just granulated sugar, plz let me know your results because I am intrigued.
