This recipe was originally posted December 2013. It was updated November 2019.
On day 8 of the 25 Days of Baking, I watched The Santa Clause where Judy the elf took her time perfecting her hot chocolate recipe. “My own recipe. Took me 1,200 years to get it right.” I didn’t spend quite as many years working on this hot chocolate brownie recipe, but it is just as delicious.
If you like moist, fudgy brownies this is your recipe. When you bite into this treat, you first feel the smooth, rich texture, and then taste the sweet, chocolate flavor. Topped with mini marshmallows, these brownies will surely put you in the mood for winter.
Overview: How to make hot chocolate brownies
So what’s the difference between hot chocolate brownies and regular brownies? Well, obviously there are the marshmallows, but then there’s also the increase of cocoa powder and use of melted chocolate. You really have to get the cocoa flavor in there to mimic the wintry drink.
To make hot chocolate brownies, you’ll need flour, sugar, butter, eggs and vanilla in addition to the cocoa powder, chocolate and mini marshmallows. Melt the chocolate and stir in the cocoa powder first so it has time to cool slightly. Beat the eggs, sugar and vanilla in a large bowl, then whisk in the melted chocolate. Finish off the batter with flour, a bit of salt and marshmallows folded in. Then top it off with more mini marshmallows on top!
How to melt chocolate
There are two ways to melt chocolate: in a makeshift double boiler or in the microwave. I prefer the makeshift double boiler because I have more control over how evenly the chocolate melts. Fill a medium sauce pan with about a cup of water and bring to a simmer. Place a larger heat safe glass bowl on top of the pan so it doesn’t submerge into the water. Put chocolate chips and butter in the glass bowl and allow them both to melt. Stir occasionally and once smooth remove from heat.
Alternatively, you can melt the chocolate and butter in the microwave. Place both ingredients in a microwave-safe glass bowl. Heat for 1 minute at 50% power level. Stir and repeat in 30 second intervals at 50% power level until chocolate is melted. Never add water to melted chocolate as it will seize up.
Can you make brownies with hot chocolate mix
Yes, technically you can make brownies using hot chocolate mix. However, hot chocolate or hot cocoa mix contains added sugar and sometimes artificial flavors and preservatives. To keep this recipe more wholesome, I chose to use unsweetened cocoa powder instead. If you do choose to use hot chocolate mix, decrease the amount of sugar by 1/4 cup for this recipe.
In my opinion, unsweetened cocoa powder provides more of that cocoa taste hot chocolate is known for. This is essential in these brownies since they are going in the oven! It’s also nice to have control in how much sugar is going in to your brownies.
