This creates a smooth, rich, and incredibly decadent topping that perfectly balances the intensity of the chocolate brownie. To complete the festive look and add another layer of texture, a sprinkle of extra chopped Oreos and bright red hots candies provide that iconic Grinch aesthetic – a heart that’s ready to burst with holiday cheer!

Simple Yet Impressive: Baking Grinch Brownies
Don’t let the decadent appearance fool you; making these Grinch Brownies is simpler than you might think. We start with a high-quality brownie mix, which saves time without compromising on flavor or texture. The magic happens with the additions: the mint Oreos baked into the batter and the homemade white chocolate ganache. Even if you’re new to making ganache, our clear, step-by-step instructions will guide you to a perfectly smooth and luscious frosting every time. It’s a recipe designed for success, ensuring you can enjoy the baking process as much as the eating!
Tips for Perfect Grinch Brownies Every Time
- Don’t Overmix the Brownie Batter: Overmixing develops gluten, leading to tougher brownies. Mix just until the ingredients are combined.
- Cool Completely: Resist the urge to frost warm brownies! The ganache will melt. Patience is key for a beautifully set top.
- Quality Ingredients: While a boxed mix is a great shortcut, using good quality white chocolate chips and heavy cream for your ganache will make a noticeable difference in flavor and texture.
- Adjust Peppermint to Taste: Some prefer a subtle hint of mint, while others love a strong burst. Start with 1/4 teaspoon of peppermint extract and add more incrementally until you reach your desired flavor.
- Gel Food Coloring for Best Color: Gel food coloring provides a much more vibrant and concentrated color than liquid food coloring, which is perfect for achieving that iconic Grinch green without adding too much moisture.
- Clean Cuts: For perfectly neat squares, use a sharp knife. For even cleaner cuts, run your knife under hot water and wipe it dry before each slice.
Storage Suggestions
These Grinch Brownies can be stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. If refrigerated, allow them to come to room temperature for about 30 minutes before serving to ensure the best fudgy texture and creamy ganache. They also freeze beautifully for longer storage; wrap individual brownies tightly in plastic wrap, then place them in a freezer-safe bag or container for up to 2-3 months. Thaw at room temperature when ready to enjoy.
These enchanting Grinch Brownies are more than just a dessert; they’re an experience! They embody the festive spirit of the holidays, bringing smiles and delicious memories. So gather your ingredients, put on some festive tunes, and get ready to bake a batch of holiday magic that will make everyone’s heart grow three sizes!

Grinch Brownies Recipe
Ingredients
- 1 (9×13 inch) box of brownie mix (and ingredients required on package, e.g., eggs, oil, water)
- 26 Mint Oreo cookies , chopped (approx. 1 ½ sleeves)
- 2 C white chocolate chips
- 1/2 C heavy cream
- 1/4 – 1/2 teaspoon peppermint extract
- 4-6 drops of leaf green food coloring (gel food coloring provides a richer color)
- red hots candies (for Grinch heart decoration)
Instructions
-
Prepare Your Workspace: Preheat your oven to a precise 350 degrees Fahrenheit (175°C). Ensuring your oven is at the correct temperature is crucial for evenly baked brownies.
-
Prep the Baking Dish: Line a 9×13 inch baking dish with parchment paper, leaving an overhang on the sides. This “sling” will make it incredibly easy to lift the cooled brownies out of the pan for clean cutting. Set the prepared dish aside.
-
Mix the Brownie Batter: Prepare the brownie mix according to the package directions. Typically, this involves combining the mix with eggs, oil, and water. Mix until just combined; be careful not to overmix, as this can lead to tough brownies.
-
Add the First Layer of Mint Oreos: Take 16 of your Mint Oreo cookies and chop them into quarters. Gently fold these chopped cookies into the prepared brownie batter. These will bake directly into your brownies, adding pockets of minty-chocolate crunch.
-
Prepare Remaining Topping: Chop the remaining 10 Mint Oreo cookies into quarters and place them in a separate small bowl. These will be used for sprinkling on top of the ganache later, providing a delightful visual and textural contrast. Set aside.
-
Bake the Brownies: Pour the brownie batter evenly into your prepared 9×13 inch pan. Use an offset spatula or the back of a spoon to ensure a smooth, level surface.
-
Bake to Perfection: Bake in the preheated oven at 350 degrees Fahrenheit (175°C) for 30-35 minutes. Baking times can vary slightly depending on your oven, so keep an eye on them.
-
Check for Doneness: To check if your brownies are perfectly cooked, insert a wooden skewer or toothpick into the center. It should come out with moist crumbs attached, but not wet batter. Avoid over-baking for that signature fudgy texture.
-
Cool Completely: Once baked, remove the baking pan from the oven and place it on a wire rack. Allow the brownies to cool completely in the pan before proceeding. This step is crucial for the ganache to set properly without melting.
-
Prepare for Ganache (Double Boiler Method): While the brownies are cooling, begin preparing your luscious ganache. Fill a saucepan with about an inch or two of water and bring it to a gentle simmer over medium heat.
-
Melt White Chocolate & Cream: Place a heat-safe bowl (preferably glass or stainless steel) on top of the simmering saucepan, ensuring the bottom of the bowl does not touch the water. Pour the white chocolate chips and heavy cream into this bowl. Stir constantly with a silicone spatula or whisk until the white chocolate is completely melted and the mixture is smooth and glossy. Remove the bowl from the heat once combined.
-
Infuse with Peppermint: Stir the peppermint extract into the warm white chocolate and heavy cream mixture. Start with 1/4 teaspoon and taste. If you desire a stronger mint flavor, you can add up to 1/2 teaspoon total.
-
Achieve Grinch Green: Now, add 4-6 drops of leaf green food coloring to the ganache. Stir very well to fully combine and achieve that iconic, vibrant Grinch green color. Add more drops if a deeper shade is desired. Gel food coloring typically provides a more intense color with fewer drops.
-
Frost the Brownies: Once the brownies are completely cool, quickly pour the warm, green ganache evenly over the top. Work relatively fast as the ganache will start to set.
-
Decorate with Toppings: Immediately sprinkle the reserved chopped Mint Oreos evenly over the ganache. Then, strategically place the red hots candies to resemble the Grinch’s growing heart, or simply sprinkle them for a pop of festive color.
-
Chill to Set: Transfer the brownie pan to the refrigerator and chill for at least an hour. This allows the ganache to firm up beautifully, making the brownies easier to cut and handle, and ensuring a clean finish.
-
Cut and Serve: Once the ganache is set, use the parchment paper overhang to lift the entire brownie slab out of the pan. Place it on a cutting board. Using a sharp knife warmed under hot water (and wiped dry between cuts), cut the brownies into neat bars or squares.
-
Indulge & Enjoy: Serve your magnificent Grinch Brownies and watch them disappear! These are best enjoyed at room temperature for the ultimate fudgy texture and ganache creaminess, but are also delicious chilled.
