Why You'll Love This Recipe

- Soft marshmallow topping. Mini marshmallows are added while the brownies are hot, then briefly returned to the oven so they become soft and puffy.
- Rich chocolate flavor. Chocolate brownies, marshmallows, and chocolate ganache make these an extra-decadent holiday treat.
- Perfect bite-size portions. Baking the brownies in a mini muffin pan creates individual brownie bites that are easy to serve and package.

Tips and Tricks
- Use a medium cookie scoop. A 2-tablespoon scoop makes portioning the brownie batter quick and gives you evenly sized brownie bites.
- Don't overfill the muffin pan. The brownie batter will rise as it bakes, so leave room at the top of each cup.
- Don't overcook the marshmallows. You're only trying to soften and puff them up. If you leave them in the oven too long, they'll become hard and chewy instead of soft.
- Let the brownies cool before removing them. Don't try to pull the brownie bites out of the pan while they're hot. Let them cool for 15-20 minutes first, then carefully run a sharp knife around the edges.
- Make the ganache in short intervals. Chocolate can easily overheat in the microwave. Heat it for 30 seconds, stir, then continue in 15-20 second intervals until smooth.
- Add sprinkles before the glaze sets. If you're using Christmas sprinkles, add them immediately after drizzling the ganache so they stick.
Ingredients

Brownie Bites
- Brownie mix: A standard 18-ounce box of brownie mix makes this recipe quick and easy. You'll also need the eggs, water, and oil called for on the package.
- Mini marshmallows: Mini marshmallows are placed on the hot brownies and briefly returned to the oven so they become soft and puffy.
Ganache
- Chocolate chips: I prefer semisweet chocolate chips because they balance the sweetness of the marshmallows. Milk chocolate can also be used if you prefer a sweeter glaze.
- Butter: Butter adds richness and helps keep the chocolate glaze smooth and pourable.
- Milk: You don't need heavy cream for this ganache. Milk creates a smooth, pourable glaze while keeping the ingredient list simple.
- Honey: Honey helps give the chocolate glaze a smooth texture and keeps it soft enough to drizzle.
- Christmas sprinkles: Sprinkles are optional but make these brownie bites especially festive for Christmas.

How To Make Hot Cocoa Brownies

Step 1: Mix brownie mix according to the directions on the box.
Grease a mini muffin pan with nonstick cooking spray. Use a medium cookie scoop (2 Tbsp. size) to scoop batter into the muffin pan.
Bake brownies at 350 degrees for 13-15 minutes.

Step 2: Immediately top each brownie bite with 4 mini marshmallows as soon as they come out of the oven.
Place brownie bites BACK INTO THE OVEN and bake for another 2-3 minutes until marshmallows look slightly puffy. DO NOT OVERCOOK MARSHMALLOWS.

Step 3: Allow brownies to cool in the pan for 15-20 minutes, then transfer to a wire cooling rack.
Use a sharp knife around the edges of each brownie. This will make them easy to remove from the pan.
NOTE: DO NOT try to remove the brownies from the pan while still hot. If you allow them to cool they are much easier to remove.

Step 4: Melt glaze ingredients together in the microwave for 30 seconds. Stir. Heat for an additional 15-20 seconds and stir until melted and smooth. Drizzle the ganache over brownies or add a small spoonful on the top of each one (about a teaspoon).
Add sprinkles, if desired.
How to Store Hot Cocoa Brownie Bites
Store the brownie bites in an airtight container at room temperature for 3-5 days.
For the best texture, let the chocolate glaze set completely before stacking them. If you need to stack them, place parchment paper between the layers.
Hot Cocoa Brownies FAQs
You can use a boxed mix or homemade brownies for this recipe. If using my homemade brownie bites recipe, it will make 36 bites, so you will need 144 mini marshmallows and an extra half batch of ganache.
The brownies are topped with marshmallows as they come out of the oven, then returned to the oven for a couple more minutes. This allows the marshmallows to get nice and soft.
A chocolate ganache glaze is drizzled over the brownies, and sprinkles are added to make them fun and festive. The ganache says soft, but sets up enough to easily store the brownies in a container.
The marshmallows were probably baked too long. You only need to heat them until they're slightly puffy and soft. There's no need to brown them.
Absolutely. I prefer semisweet chocolate because the marshmallows and brownie mix are already sweet, but milk chocolate works if you prefer a sweeter dessert.
You can, but the mini muffin pan is what gives you the individual brownie bites. You could bake the brownies in another pan and cut them into small squares, then add the marshmallows and glaze.
They're best within 3-5 days when stored in an airtight container at room temperature.
