Ingredients

Ingredient Notes

• Chocolate Chips – you’ll need both white chocolate chips and semi-sweet chocolate chips for this recipe. I always recommend high-quality chocolate chips like Nestle or Ghirardelli but anything works.
• Green food coloring – I used the green from this McCormick Neon food coloring to get a good Grinch green color.
• Butter – you’ll want to use unsalted butter in this recipe. If you don’t have unsalted, I recommend reducing the amount of added salt to just 1/4 tsp instead of 1/2 tsp. You can either melt your butter before adding to the double boiler or just let them melt together.
• Heart Sprinkles – I used these Wilton Jumbo Heart Sprinkles in the video in this post because I liked the larger size. You can really use any red heart sprinkles you want. There are a ton of options available on Amazon or at places like Michaels or Hobby Lobby.
• Mint Oreos – these are one of the best parts of these brownies so don’t skip them! You can also use regular like I used in my brownies with cookie dough and Oreos.

How to Make Grinch Brownies

While these brownies are a little more difficult than making a box of brownies, they’re still not tough. It’s just a matter of adding ingredients together then baking.

And the end result is totally worth a little more added effort!

Start by preheating the oven to 350 degrees.

Then line a 9×13 baking dish with parchment paper or foil, making sure the parchment paper is long enough to go over the ends of the baking dish. This will make cleanup and perfect cutting so much easier!

I also recommend spraying the parchment paper but it’s not absolutely necessary – just guarantees they won’t stick!

Make the Brownies

The first thing you need to do is make the homemade brownies. We’ll talk about that pretty green ganache a bit later on.

Add your butter and semi-sweet chocolate chips to a double boiler on the stove and let them melt together. Once melted, whisk together to combine completely.

After they’re combined, add your vegetable oil to the chocolate mixture and mix it in well.

While the chocolate mixture is melting (it takes a few minutes), combine the sugar, brown sugar, vanilla, salt, eggs, and egg yolks in a large bowl and mix. You can either do this in a stand mixer, with a hand mixer, or just by hand. It comes together pretty easily.

Add the finished chocolate mixture to your sugar mixture and whisk until everything is well combined. I feel like I say that phrase a lot but that’s really what you’re doing – combining them until it’s just one mixture.

Gently fold in the flour and cocoa powder into the mixture.

Keep folding gently with a silicone spatula until the dry ingredients are just mixed into the wet ingredients. You don’t want to over mix or you may end up with tougher brownies than you want.

Pour the brownie batter into the baking pan you prepped earlier then place 12 Mint Oreos on top of the batter, then gently press down so they are engulfed into the brownie batter.

I like to space the Oreos out so that if you cut the brownies into 12 bars, everyone would get a brownie in their piece.

Place the brownies in the oven and bake for 30 to 35 minutes or until you can put a toothpick in and it comes out cleanly. A little cooked brownie on it is fine, but you don’t want it to still have gooey brownie batter on it.

Remove from the oven and let the brownies cool while you make your ganache.

Make the grinch Ganache

Put your white chocolate chips in a medium bowl that’s heat safe. You’ll see why in a minute.

Then heat your heavy cream on the stove over medium heat until it comes to a simmer, don’t let it boil.

As soon as it’s simmering, pour the hot cream all over the chocolate and let it sit for three minutes before stirring.

Stir the chocolate and cream to combine, keep stirring until you get a nice creamy ganache.

Add a few drops of the food coloring and stir. Add more food coloring if necessary and stir in completely until you get the color you want. I added about five total drops but it’s all dependent on how much you get out in each drop, etc.

Finish the Grinch Brownies

Pour the melted ganache over top of the baked brownies and spread them out with a knife.

Sprinkle the heart sprinkles over the brownies, making sure each bar will have some hearts when cut.

Let the brownies sit for at least an hour before cutting to allow the ganache to set on top. It will never harden, but it will set enough to allow you to cut them.

Remove the parchment paper from the baking dish, peel the parchment away from the brownies, and cut into your desired amount of squares to serve.

Expert Tips

Use a silicone spatula to spread out the brownies in the pan and again to spread out the ganache. It spreads things out smoother and doesn’t stick as much as a knife.

Make sure to push the Mint Oreos down into the brownie batter. If you bake them right at the top, they’ll be visible through the green ganache on top. If you forget, you can always lightly press them down once the brownies are baked as well, or even after the ganache is on top (when you see them popping through).

Double up on the sprinkles by adding red holiday sprinkles and the red sprinkle hearts. Or if you want to make these just Christmas brownies, you can skip the hearts altogether and just make them red and green brownies.

Store the brownies in an airtight container or back in the pan topped with plastic wrap for up to five days.
