Step-by-Step Instructions for Monster Brownies
Making these brownies feels like a craft project you can eat afterward.
Bake the Brownie Base
Mix and bake the brownie mix as directed on the box. Let them cool fully before cutting. Warm brownies can fall apart, so chilling them until firm makes decorating much easier.

Add the Green Face
Mix a few drops of green food coloring into the chocolate frosting. Spread it over each brownie square to create Frankenstein’s “skin.”
Decorate the Monsters
Place candy eyes on each brownie. Use black gel to draw hair, scars, and mouths. Stick pretzels into the sides as bolts. Add M&M’s for noses or funny details. Each monster can look different—grumpy, spooky, or silly.
Fun Variations and Creative Twists
The classic version is always popular, but you can make it your own.
Vegan Option
Swap the brownie mix for a vegan recipe. Use flax eggs, non-dairy milk, and vegan butter. Choose dairy-free frosting and vegan candy eyes. Everyone at the party can enjoy them.
Kid-Friendly Decorating
Set up bowls of candy eyes, pretzels, and gels. Let kids design their own monsters. The fun is in the creativity, not perfection.
Extra Candy Details
Add licorice strings for hair, sprinkles for scars, or red candies for stitches. These little touches make your brownies photo-ready.
If you love bold Halloween colors, you’ll also enjoy Candy Corn Swirl Brownies. They look amazing next to Frankenstein’s Monster Brownies.
The Story Behind Frankenstein’s Monster
Frankenstein’s monster first appeared in Mary Shelley’s novel Frankenstein in 1818. In the book, Victor Frankenstein creates life in his lab but fears what he has made. Movies later gave the monster its famous look—green skin, scars, and bolts in the neck.
That iconic image inspired these brownies. Decorating them is a fun way to honor a classic Halloween character.
Serving and Storing Monster Brownies
Keeping Them Fresh
Store brownies in an airtight container at room temperature for 2 days. For longer storage, keep them in the fridge for up to 4 days. Use parchment paper between layers to protect the frosting.
Fun Ways to Serve
Line the brownies up on a tray like a little monster army. Place them in cupcake liners for easy serving. Add props like pumpkins, spiders, or a Halloween tablecloth to set the scene.
