Iced Mint Oreo Brownies

Are you ready for some rich, decadent, sinfully good treats for your St. Paddy’s Day? Or really any other day of the year for that matter! These delicious frosted brownies have a lot of my favorite ingredients in them including brownies, white chocolate, Oreos and icing! Mmmmm, all you dessert lovers out there rejoice! All the ingredients you should need are pictured above.

By the time you’re done, you’ll be staring at brownies that are just as rich and beckoning as the pan pictured above. To get started here’s what you need to do.


Aluminum foil
Cooking spray
7 oz jar marshmallow fluff
1/8 t mint extract
10 drops green food coloring
1 box brownie mix
Vegetable oil (amount depends on the brownie mix)
Eggs (amount depends on the brownie mix)
17 oz package cool mint Oreo cookies
3/4 c white chocolate chips
1/4 t vanilla extract
1 canister vanilla frosting


Preheat oven to 350. Line a 9×13 pan with foil & spray it with cooking spray.

In medium bowl, stir marshmallow fluff, mint extract, & 5 drops of food coloring (or more) until light green color is achieved.

In a large bowl, prepare the brownie mix as directed on the box, using water, oil, eggs, & fold in 12 hand crumbled Oreos at the end.

Spread brownie batter in prepared pan. Place random dollops (about 1/2 c) of the green marshmallow mixture on top of  brownie batter & save the rest for later. Gently pull a table knife through batter in S-shaped curves for a swirled looking top to your brownies. Bake until brownies are set, being careful not to overbake. I originally set my timer for 25 minutes but ended up having to bake them for around 40 minutes until they were done in the center.

Cool brownies completely before icing.

In another small microwave-safe bowl, melt the white chocolate chips for 30 second intervals.  Take out the chips and stir in between each 30 second intervals until they are completely melted and smooth.

Add the melted white chocolate chips, vanilla extract, & the vanilla frosting to the reserved marshmallow mixture. Stir in 5 drops of food coloring or until your desired level of green is achieved. Once the ingredients are blended, spread over cooled brownies. Crumble Oreos by hand and sprinkle them over the brownies, pressing them in lightly. Let it set before slicing and serving.
