Introduction & Inspiration
This recipe for Mint OREO® Cookies M&M’s® Brookies is a celebration of all things delicious and over-the-top. It combines the best of three worlds: fudgy brownies, chewy sugar cookies, and the refreshing crunch of mint-flavored OREO® cookies and M&M’s®. I love to combine flavors.
The inspiration came from a desire to create a dessert that was both impressive and relatively easy to make. I wanted something that would be a showstopper at a party or potluck, but that wouldn’t require hours of complicated baking.
The combination of brownies and cookies (brookies!) is always a winner, and the addition of mint OREO®s and green M&M’s® makes these bars perfect for St. Patrick’s Day, or any time you’re craving a mint-chocolate treat.
I’m excited to share this recipe because these brookies are seriously addictive. They’re rich, decadent, and full of different textures and flavors. They’re also a great way to use up leftover brownie mix or cookie mix.
Nostalgic Appeal
Brookies, the combination of brownies and cookies, are a relatively modern invention, but they tap into the nostalgic appeal of both classic desserts. Brownies and cookies are two of the most beloved baked goods, often associated with childhood memories and comforting treats.
The addition of OREO® cookies and M&M’s® adds another layer of nostalgia. These popular candies are often associated with fun, indulgence, and special occasions.
The mint flavor, especially when combined with chocolate, can also evoke memories of holidays and festive treats. It’s a flavor combination that’s both refreshing and comforting.
And that’s the beauty of these brookies – they combine the familiar comfort of classic desserts with the fun and excitement of popular candies, creating a treat that’s both nostalgic and incredibly satisfying.
Homemade Focus
While this recipe uses boxed mixes for both the brownies and the cookies, it still embodies the spirit of homemade baking. It’s about taking simple, readily available ingredients and transforming them into something special with your own hands. Semi-homemade.
It’s a reminder that you don’t have to be a professional baker to create a delicious and impressive dessert. Sometimes, the best treats are the ones that are easy to make and fun to share.
There’s a sense of satisfaction that comes from putting together a dessert that you know your friends and family will enjoy, even if it starts with a few shortcuts.
This recipe is also an invitation to get creative in the kitchen. Don’t be afraid to experiment with different flavors of OREO® cookies, M&M’s®, or even different types of brownie and cookie mixes.
Flavor Goal
The primary flavor goal of these Mint OREO® Cookies M&M’s® Brookies is to create a rich, decadent, and multi-layered dessert with a perfect balance of chocolate, mint, and a hint of sweetness from the sugar cookie layer. We want the fudgy brownie base to be complemented by the chewy sugar cookie, the creamy mint OREO®s, and the crunchy M&M’s®.
The brownie layer provides a deep, dark chocolate flavor and a fudgy texture. The sugar cookie layer adds a touch of sweetness and a slightly crisp, chewy texture.
The mint OREO® cookies contribute a refreshing mint flavor and a creamy, crunchy element. The green M&M’s® add a pop of color and an extra burst of chocolate.
Ultimately, the flavor goal is to create a dessert that’s both indulgent and satisfying, a perfect combination of different flavors and textures that will appeal to everyone. It is a symphony of flavors.
