    These cute Monster Bash Brownies are one of my favorite and cutest treats I like to make during Halloween! They’re surprisingly easy to make and it’s the perfect treat to pair with one of my family’s favorite Halloween-time traditions that we are sharing!

    It’s a Monster Bash! Make your monsters your own—change the color, change the decorations, and have fun!

    First up, these cute Monster Bash brownies! You’ll see I did two different versions—the purple monsters and the white ghosts!

    Feel free to get creative, change the ganache color, give them multiple eyes, get a little crazy with the frosting decorations. You can use sprinkles, gel frosting, edible glitter—they’re monsters, so just about anything goes!

    Do I need to follow this brownie recipe? Can I use a box mix?

    The brownie recipe I’ve used is an adaptation from King Arthur Flour. It’s a great recipe to have on hand, it’s the perfect combination of a chewy and fudgy brownie. This recipe reminds me of the brownies you’d pick up in a bakery, they make a great sturdy base for these monster bash brownies!

    But, if you’re not feeling like whipping up brownies, you can always use a box mix. We’re actually big fans of box mix brownies at our house, shhhhhh! If you do use a box mix, the one thing you really want from these brownies is to make them thick so they have a sturdy base for your monsters to sit on and for you to decorate. So either make them in a small pan (like an 8x8 or 9x9) or double the recipe or box mix for a 9x13.

    Our favorite Halloween tradition and FREE printable!

    Next up, I want to explain our favorite Halloween tradition. Now, I’m sure many of you guys have already done this before or maybe it’s even a favorite tradition of your family too! We call it “BOOing” someone! Basically, what you’ll do is whip up two plates of treats (like these Monster Bash brownies!), print off two copies of this cute poem I wrote and designed for you, and sneakily dingdong ditch them at two of your neighbors’ or friends’ homes. If and when you get BOOed you will tape the poem to your door or in a window where it can be seen so that everyone knows you’ve already been BOOed. It’s a super fun thing to do with your family and gets everyone into the Halloween spirit!

    How to Make the Ganache

    The white chocolate ganache is a simple mixture of hot cream, white chocolate, and a touch of salt, mixed together until smooth. Its thin enough to pour over your marshmallows but thick enough to coat the marshmallows.

    If you do decide to color your ganahce, like how mine are purple in the pictures, make sure you use a gel based food coloring. A water-based one could make your chocolate seize (get thick and difficult to mix).

    How to substitute cream in this recipe

    The white chocolate ganache in this recipe calls for 2 ½ tablespoons of cream, but if you don’t want to buy a whole pint of cream for 2 ½ tablespoons, I’ve got a simple substitution for you!

    • 2 ½ tablespoons of cream = with 1 ¾ tablespoons of milk + ½ tablespoon melted butter

    Enjoy!

    Instructions

    • Preheat oven to 350 degrees Fahrenheit. In a large bowl mix together eggs and cocoa powder, set aside. In a microwave safe bowl add butter and both sugars. Microwave for 90 seconds, stirring every 30 seconds. Cool until warm, but not hot. Slowly mix in egg and cocoa powder mixture.
    • Stir in baking powder, salt, vanilla, and flour. Let cool slightly, then stir in chocolate chips.
    • Line a 9x9 inch pan with foil. Grease foil or spray with cooking spray. Evenly spread batter in pan. Bake for 25 minutes. Remove and cool completely before decorating.
    • In a microwave safe bowl, heat cream for 30 seconds. Add white chocolate chips let sit with cream for 1 minute. Keep stirring until smooth. If necessary, microwave in 15 second increments until smooth. Stir in salt and food coloring if desired.
    • Cut brownies into 9 equal pieces. Add a little bit of ganache mixture to the bottom of each marshmallow and stick on top of brownies. Stick in the fridge for 5 minutes.
    • Drop a spoonful of ganache on top of the marshmallow, using your spoon coax the ganache down the marshmallow and onto the brownie. If needed, add more ganache to the top of the marshmallow. Repeat for all brownies. If adding candy eyes add now. Chill until solid before decorating the rest. Use gel decorating icing to draw faces. Serve and enjoy!
