What You’ll Need

Ingredients for Frankenstein Brownies neatly arranged on a table.
Gather your ingredients and get ready to bake these monstrously delicious brownies!

Here’s what you’ll need to create these delightful Frankenstein Brownies:

  • One box of your favorite brownie mix (plus the ingredients called for on the box – usually eggs, oil, and water)
  • 1/2 cup green frosting (you can buy pre-colored or tint it yourself with food coloring)
  • Candy eyes (small and medium sizes work well)
  • Chocolate chips (mini or regular size) – these will be our Frankenstein “bolts”
  • Black gel icing for adding those spooky details

Don’t feel limited by this list. You can always add your own creative touches!

From Start to Finish

Step 1: Bake the Brownies

Preheat your oven according to the instructions on the brownie mix box. Grease a baking pan (the size will depend on the brownie mix you’re using – 8×8 or 9×13 are common). Prepare the brownie batter as directed on the box and pour it into the prepared pan.

Step 2: Bake and Cool

Bake the brownies according to the box instructions. Baking times will vary, so be sure to keep an eye on them and check for doneness with a toothpick. Once baked, remove the brownies from the oven and let them cool completely in the pan before moving on to the next step.

Step 3: Frost the Brownies

Once the brownies are completely cool, frost the entire surface with green frosting. You can spread it evenly with a knife or spatula.

Step 4: Create the Faces

Now for the fun part! Add two candy eyes to each brownie, positioning them towards the top. Use mini chocolate chips for the “bolts” on either side of the face, pressing them gently into the frosting.

Step 5: Draw the Details

With the black gel icing, draw Frankenstein’s signature hairstyle – a few jagged lines across the top of the brownie, above the candy eyes. Then, draw a stitched line for his mouth just below the candy eyes. Your Frankenstein faces are complete!

Better-Than-Grandma Tips

Use black gel icing to draw Frankenstein’s iconic hair and stitched mouth.
  • For extra fudgy brownies, slightly underbake them. Start checking for doneness a few minutes before the box instructions suggest. You want a toothpick inserted into the center to come out with a few moist crumbs attached, not completely clean.
  • Let the brownies cool completely before frosting. This prevents the frosting from melting and helps create a stable base for your decorations. You can speed up the cooling process by placing the pan on a wire rack.
  • Use a piping bag or a zip-top bag with a corner snipped off for precise application of the black gel icing. This will give you better control when drawing Frankenstein’s hair and mouth.
  • If you don’t have black gel icing, you can melt some dark chocolate chips and use a toothpick to draw the details.
  • Don’t be limited to brownies! Apply the same decorating techniques to our pumpkin spice cookies for a whole new Halloween favorite.

Try These Variations

  • Monster Mash-Up: Use different colored frostings and candies to create a variety of monster faces. Think purple frosting with orange sprinkles for a one-eyed monster, or blue frosting with white chocolate chips for a cool ghoul.
  • Spooky Swirls: Instead of frosting the entire brownie, create swirls of green frosting on top and add the candy decorations on top of the swirls. This adds a fun texture and makes the decorations pop.
  • Ghostly White Chocolate: Melt white chocolate chips and drizzle them over the green frosting for a ghostly effect. You can even add mini marshmallows for extra spookiness.

Can I use a different kind of brownie mix?

You can use any type of brownie mix you like for this recipe, from fudgy to cakey. Just be sure to follow the baking instructions on the box for perfect brownies every time.

Can I decorate the brownies differently?

Absolutely! Get creative with your decorating! You could use different colored frosting, sprinkles, or even edible markers to add unique details to your Frankenstein faces.

How should I store the Frankenstein Brownies?

These brownies are best served fresh, but you can store them in an airtight container at room temperature for up to 3 days. If you live in a warm climate, consider keeping them in the fridge to prevent the frosting from melting.

Can you suggest a flavor variation for the frosting?

For a fun twist, try adding a layer of green-tinted cream cheese frosting under the green buttercream. The tangy flavor pairs perfectly with the rich chocolate brownie.
