How do you Celebrate Saint Patrick's Day?
There is nothing that I love more than freckled folks, Jameson Irish Whiskey and green food coloring in my food during Saint Patrick's Day celebrations throughout the month of March.
This year, I will be spending Saint Patrick's Day in Manhattan with my gal pal. We will most likely spend the day stuffing our face with mint Oreo cookies and watching whatever madness unfolds at the New York City Saint Patrick's Day parade.
I am quite certain that there will be shots of Jameson involved. I may even wear a "Kiss me, I'm Irish" button on my jacket!
This recipe was inspired by my Saint Patrick's Day Irish Cream Fudge recipe that I think you will also love!

They say that everyone is Irish on Saint Patrick's Day, but some of us are a little more Irish than others...according to my 23andMe DNA report, I am about 42.7% English/Irish.
This may explain why I feel such an affinity for the Irish culture and folklore - and amazingly flavorful Irish food!

Mint Oreo Dessert Ingredients you will need to begin gathering
- A box of your favorite Brownie mix - and of course, the ingredients to make the brownies, which is usually just vegetable oil and eggs
- Oreo cookies - it is perfectly fine to use mint Oreo cookies or regular Oreo cookies
- Mini marshmallows - I like to keep a bag of mini marshmallows in the freezer, you know, just in case I want to throw some on a dessert I am making
- Mint M&Ms candies - this is a newer flavor of M&Ms and we absolutely LOVE it!
- Peppermint oil or mint extract - we like LorAnn Bakery Emulsions for cooking, but you can also use regular peppermint extract in this recipe
Equipment you will need to make this mint Oreo recipe
We used a Wilton 9" tart and quiche pan. I love this pan because the bottom is separate from the sides, so it is easy to remove from the pan. If you do not have one of these pans, I would suggest you cover whichever pan you use very tightly with foil so that you can remove the brownie easily. You can buy the pan we use on Amazon here.
How to Make This Mint Oreo Dessert Recipe
You will begin making this recipe by greasing your tart pan or baking dish and setting it aside.
Crush 10 Oreos in a bowl with a tart shaper or place in a Ziplock bag and crush with a rolling pin. Set aside. Crush remaining 5 cookies and set aside.
In a large mixing bowl, prepare brownies as directed on box and stir in the ½ tsp mint extract or peppermint oil and 10 crushed Oreos.
Pour the Oreo dessert mixture into your prepared tart pan and then we are going to bake dessert recipe for 18-20 minutes or until the center of our brownie is done. Sprinkle with marshmallows and bake for an additional 1-2 minutes or until marshmallows double in size.
Remove from oven and sprinkle with crushed Oreos and M&Ms. Let cool completely before cutting.
