St Patrick’s Day Dessert Idea- Ultimate Mint Oreo Brownies

Who can resist those mint Oreos on the shelves this time of year, especially when the end result is these Ultimate Mint Oreo Brownies? I know that lent is upon us but I am sure you can indulge a little on St. Patrick’s Day, especially if you are Irish.

These brownies were so thick and rich, my kids could not eat a whole one. To be honest, I usually use a Box brownie mix when I create variations of brownie desserts, but I saw this recipe and could not resist trying it from scratch.

There are no surprise ingredients, just unsweetened chocolate, so just be sure you have a box of that around.

Variations to Mint Oreo Brownies

These brownies are perfection but if you are looking for variations try:

  • Make them as Blondies
  • Don’t Make Mint – There are many types of Oreos and you can change the flavor of these brownies simply by changing the Oreos.

Ingredients in Mint Oreo Brownies

  • Butter
  •  unsweetened chocolate,
  • all purpose flour
  •  white sugar
  • baking powder
  •  sugar
  • salt
  • vanilla extract
  •  eggs
  •  Oreo cookies

To make these Mint Oreo Brownies,  start by chopping up the chocolate fairly small and I would recommend either starting with room temperature butter or cutting it into pieces to quicken up the melting process.

Now unlike me the first time, don’t forget to add your flour, oops but it was all good in the end. Add your cooled chocolate, I added a small amount first to allow it to adjust to the egg temperature.

Stop the mixer and stir in half of your Chopped mint Oreos.



Spread into a 9×9 square pan either lined with tin foil that is sprayed or I used pan lining paper which makes cutting your Mint Oreo Brownies a breeze, not to mention the cleanup.

Top with the remainder of your chopped Mint Oreos.
