Ingredients

• Brownies: One 8x8 pan of baked brownies (homemade or boxed), cooled completely
• Hot cocoa mix: 1/3 cup (regular or dark chocolate)
• Mini marshmallows: 1 cup (or dehydrated marshmallows for extra chew)
• Chocolate for coating: 12–16 oz semisweet or milk chocolate chips, melts, or chopped bars
• Coconut oil or shortening: 1–2 teaspoons (optional, for smoother melting)

• Pinch of salt: To balance sweetness
• Optional toppings: Crushed candy canes, cocoa powder, sprinkles, flaky sea salt, or white chocolate drizzle

Instructions

• Bake and cool the brownies: Prepare an 8x8 pan of brownies and let them cool fully. Chilling for 30 minutes helps them firm up.

• Form the brownie balls: Crumble the brownies into a mixing bowl. Add a pinch of salt and vanilla if using. Squeeze and roll into 1.5-inch balls.Flatten each ball slightly, add a teaspoon of cocoa mix and a few marshmallows, then wrap the brownie around to seal. Roll smooth.
• Chill: Place the filled balls on a parchment-lined sheet and chill for 20–30 minutes. This helps them hold together when dipped.
• Melt the chocolate: Microwave chocolate with 1–2 teaspoons coconut oil in 20–30 second bursts, stirring between each, until smooth.Or melt in a double boiler.
• Dip and coat: Using a fork, dip each chilled brownie ball into the melted chocolate, letting excess drip off. Place back on the parchment.
• Decorate: While the coating is wet, sprinkle with crushed candy canes, sprinkles, or flaky salt. For a white chocolate drizzle, wait until the coating sets, then drizzle.
• Set and serve: Let the chocolate harden at room temperature or chill for 10–15 minutes.Serve slightly chilled or at room temp.

FAQ

Can I use box mix brownies?

Yes.

Bake them a little fudgier by slightly underbaking, then chill before shaping. They roll better and taste ultra rich.

Do I need to temper the chocolate?

No. For home baking, melting with a bit of oil works fine.

If you want extra shine and snap, you can temper, but it’s optional.

Why are my brownie balls cracking?

They’re either too dry or too cold. Warm them in your hands for a few seconds, or mix in a teaspoon of chocolate ganache or frosting to help bind.

What if my marshmallows melt into the brownie?

That’s normal and delicious. For a more distinct marshmallow bite, use dehydrated marshmallows or add them right before chilling.

How big should each bomb be?

Aim for 1.5-inch balls, about 1.5–2 tablespoons of brownie mixture each.

This size coats easily and gives a balanced bite.

Can I make them dairy-free?

Yes. Use dairy-free brownie mix, dairy-free chocolate, and a cocoa mix without milk powder. Many brands offer vegan options.

In Conclusion

Hot Cocoa Brownie Bombs bring everything you love about winter desserts into one bite: fudgy brownie, cozy cocoa, and a crisp chocolate shell.

They’re simple, flexible, and guaranteed to impress. Make a batch for your next gathering or gift box, and watch them disappear fast. Cozy season or not, these little bombs hit the spot.
