Preheat oven to 350* Prepare brownie mix according to package directions; pour into a gallon zip lock bag.
In a 24cnt. mini muffin pan; place paper liners, and drop 1 oreo cookie into each well. Snip off the corner of the zip lock bag, and pipe brownie mix over the cookie filling to almost the top.
Bake 12-15min. While they are baking; unwrap the mint candies and cut each one in half..1 pkg. will do 24 bites exactly. Once the bites are baked remove from oven and place mint candy on top of each bite; place back in the oven for 1 min. 30sec. remove and using the back of a spoon immediately spread the melted candy to make icing on the bites... You will have enough brownie mix and candies to make 2 batches or 48 bites!!! Enjoy!!
