Triple Layer Fudgy Mint Oreo Brownies Ingredients

For the Brownie Base

Baking Chocolate (Dark) – A rich chocolate flavor is key; opt for high-quality chocolate for the best results.
Unsalted Butter – This increases richness; margarine can be used as a substitute, though it may alter flavor slightly.
Granulated Sugar – Sweetens the brownies; consider reducing the amount for a less sweet dessert.
Eggs – They bind the mixture and give structure; no substitutes recommended for optimal results.
Vanilla Extract – Enhances flavors; feel free to swap with another extract for a fun twist.
All-Purpose Flour – Provides structure; for a gluten-free version, substitute with a gluten-free flour blend.
Cool Mint Oreos – Adds texture and vibrant minty flavor; regular Oreos can work but will change the mint profile.

For the Mint Marshmallow Filling

Marshmallow Fluff – Contributes to sweetness and fluff; homemade marshmallow can be an excellent alternative.
Mint Extract – Essential for that refreshing mint flavor; use sparingly to avoid overpowering the other flavors.
Green Food Coloring – Adds a festive green hue; adjust the number of drops to achieve your desired shade.

For the Topping

Creamy White Chocolate – Provides a luscious topping; melting good quality chocolate ensures a smooth finish.
Crumbled Mint Oreos – Extra crunch and flavor; feel free to use any cookie variation you prefer.

How to Make Triple Layer Fudgy Mint Oreo Brownies

Preheat the oven to 350°F (175°C) and prepare a 9×13 inch pan by lining it with foil and spraying it with cooking spray. This ensures easy removal and cleanup.
Mix together the Marshmallow Fluff, mint extract, and a few drops of green food coloring in a medium bowl until well combined. Set aside to make the filling fluffy and vibrant.
Melt the baking chocolate and unsalted butter together in a microwave-safe bowl, heating in 30-second intervals. Stir until smooth, ensuring no bits remain, then blend in the granulated sugar, eggs, and vanilla extract.
Fold in the all-purpose flour and crumbled Mint Oreos gently into the chocolate mixture until just combined. Be careful not to overmix; you want to keep it fudgy!
Pour half of the brownie batter into the bottom of the prepared pan. Swirl in half of the mint mixture on top, creating a delightful marbled effect.
Bake for 23-30 minutes, or until the edges are set and a toothpick inserted in the center comes out with moist crumbs. Allow to cool completely in the pan.
Prepare the frosting by whisking together softened butter, powdered sugar, and melted white chocolate until creamy and smooth.
Spread the frosting evenly over the cooled brownies and top with more crumbled Mint Oreos. Allow the brownies to set before slicing into squares.

Optional: Serve with a dollop of whipped cream for an extra indulgent touch.

Triple Layer Fudgy Mint Oreo Brownies Recipe FAQs

How do I select the best Mint Oreos for this recipe?
Absolutely! Look for Mint Oreos that are fresh—no broken or crushed cookies. Check the expiration date, and avoid cookies with dark spots or a stale smell. Fresh cookies will contribute to both the flavor and texture of your brownies.

What is the best way to store leftover brownies?
The more the merrier! Store your brownies in an airtight container in the refrigerator for up to 10 days. For optimal freshness, place a piece of parchment paper between layers of brownies. This helps maintain their fudgy texture while preventing them from sticking together.

Can I freeze the brownies for later?
Definitely! To freeze your Triple Layer Fudgy Mint Oreo Brownies, wrap each piece individually in plastic wrap and place them in a freezer-safe bag. They will stay fresh for up to 6 months. When you’re ready to indulge, simply let them thaw at room temperature or pop them in the microwave for a quick warm-up!

What should I do if my brownies come out too dry?
If your brownies turn out dry, it may be due to over-baking or too much flour. Next time, consider checking for doneness around the 23-minute mark. A toothpick should have moist crumbs, not dry ones. Also, be gentle when folding in the flour; aim for a silky batter to lock in moisture.

Are these brownies suitable for special diets, like gluten-free?
Absolutely! To make these Triple Layer Fudgy Mint Oreo Brownies gluten-free, simply substitute regular all-purpose flour with a gluten-free flour blend.
