Ingredients
- Cornflake cereal: Classic, crunchy, and perfect for holding the caramel mixture—don’t swap for frosted flakes unless you want super sweet cookies.
- Peanut butter: Creamy peanut butter works best here for that smooth, gooey texture. Natural peanut butter can separate, so stir well or stick with the regular kind.
- Syrup: Light corn syrup keeps everything smooth and chewy. Maple syrup works in a pinch, but it’ll change the flavor (still delicious, just different).
- Salt: Just a little salt to balance the sweet and bring out that peanut butter goodness.
- Vanilla extract: Adds warm, cozy depth—don’t skip it!
For the decoration:
- White chocolate, melted: This is your “glue” and ghost base. Use white chocolate chips or bars—just melt gently.
- Dark chocolate (for eyes and mouth): A little goes a long way! Melt and use a toothpick or skewer to dot on spooky little ghost faces.
- Marshmallows: The heads of your ghosts! Standard size marshmallows work perfectly—slice the bottoms flat if they won’t sit upright.
How To Make Halloween Ghost Cornflake Cookies
- Make the caramel base: Add the sugar, corn syrup, and peanut butter to a saucepan and warm it over medium heat. Stir the whole time so it doesn’t burn—it’ll start to melt down into a smooth, caramel-like mixture. Once it’s nice and silky, take it off the heat and stir in the vanilla and salt.
- Shape the cookies: Pour that warm mixture over the cornflakes in a large bowl. Stir gently with a spatula until everything is coated.
- Then, use a cookie scoop (a size 20 works great) to scoop little mounds onto parchment paper or a lined baking sheet. Press each one down just slightly so they hold their shape. Let them cool at room temp until they’re set.
- Decorate for Halloween: Melt your white chocolate and spoon a little bit on top of each cookie. Dip a marshmallow into the melted chocolate, tap off the excess, and set it right on top of each cookie to make your ghost. Let everything set (you can pop them in the fridge to speed this up).
- Then, grab a toothpick, dip it into melted dark chocolate, and carefully draw on spooky little eyes and mouths.
Recipe Notes
-
Add some color – Want to get creative with your ghost squad? Stir a few drops of food coloring into the white chocolate for spooky shades like green, purple, or orange.
-
Storage tips – These hold up great! Store in an airtight container at room temperature for up to 4 days. Or pop them in the fridge and they’ll last closer to a week (if they’re not devoured first).
-
Fun extras – Want to jazz them up even more? Try mini chocolate chips for extra eyes, crushed peanuts for crunch, or Halloween sprinkles to match your party vibe.
