This recipe is absolutely fantastic! It's incredibly easy to make and has quickly become my top choice for desserts when I host meals with friends or bring treats to work. Everyone always asks for more and then jokingly accuses me of being the reason for their addiction to these delicious treats :-)

Baked in a 9-inch square pan, I decided to elevate the brownie recipe by mixing in decadent bittersweet chocolate chips. To top it off, I generously spread a layer of rich chocolate fudge icing. The result? An absolute chocolate delight.

Baked in a 9-inch square pan and enhanced with bittersweet chocolate chips mixed into the brownie batter, topped off with a rich chocolate fudge icing. A true chocolate delight.

I absolutely adored this recipe! It was incredibly fast and simple to make. We tried it with vanilla Oreos for a zebra brownie variation, and also with the limited edition marshmallow Oreos. We made 16 brownies using cupcake liners, but I prefer mine thinner on both edges to achieve that crispy outer layer and delectable interior. Baking them for 23 minutes was spot on, and allowing them to cool in the pan worked perfectly.

First of all, this treat is fantastic on its own, but I took it up a notch by placing cookie dough at the base of each muffin cup before layering on the brownie and sandwich cookies. This simple addition really elevates all the flavors, creating a delightful dessert that appeals to both children and adults.

My family definitely enjoyed them, but, as another reviewer mentioned, the Oreos tend to rise to the top, making them look a bit odd and resulting in uneven distribution of Oreos. I am not sure how to fix this issue – perhaps placing the Oreos at the very bottom would help?

I thought it was fantastic! But if you have a sweet tooth like me, I suggest adding 2 Oreos per brownie instead of just 1.

I baked these using a mini muffin tin and mini sandwich cookies, and they were a hit with everyone! Definitely making them again!

Absolutely delicious! The addition of Oreos took these brownies to the next level. It was incredibly easy to make too.

I followed the recipe exactly but made one change - I used a mint patty candy instead of an Oreo. I baked them according to the same instructions and they turned out beautifully. I highly recommend trying these mint patty stuffed brownies!

Easy and delicious! Just a couple of things to note... If you use 2 eggs, you'll get a cake-like brownie. Also, the Oreos tend to rise up! Our brownies turned out looking like chocolate popovers with cute little hats!

I didn't have vegetable oil on hand, so I substituted coconut oil in this recipe. I greased the pan but skipped using liners, which made it difficult to remove the muffins from the tin as they turned out very soft. I resorted to eating a few with a spoon straight from the tin since they didn't stick but were too delicate to hold their shape. Despite the texture mishap, the muffins were delicious!
