Apple Monster Mouths have turned every Halloween at our house into a giggle-filled celebration,my kids adore building these bright,“bitey” smiles together.These snacks offer up fruity crunch,creamy peanut butter,and sweet marshmallow“teeth” in every silly bite.Whether you set out a platter for a party or serve at after-school playdates,the monsters always disappear fast.
I first discovered this snack when trying to make something festive but not loaded with sugar for a classroom party.Now it is a requested tradition every October and I love seeing little hands create their own monster mouths.
Ingredients
- Red apples: Crisp and sweet with eye-catching color Choose firm fruit without bruises for best results
- Creamy peanut butter: Adds rich flavor and holds the “mouth” together Sunflower seed butter works well for nut-free families
- Mini marshmallows: Create the “teeth” Soy or gelatin-free options are available
- Sunflower seeds: Transform into spooky fangs Use raw unsalted seeds if possible
- Chocolate chips: Give goofy “eyes” Choose high-quality chocolate for best taste
- Fresh lemon juice: Optional to keep apple slices bright and prevent browning
Instructions
- Wash and Prep Apples:
- Rinse your apples under cool water and dry thoroughly with a clean towel This ensures no wax residue or dirt gets into your snack.Using a sturdy knife and cutting board,slice each apple into eight even wedges Pat dry again if the slices are slick with juice,this helps the peanut butter stick later
- Spread Peanut Butter:
- Use a small spatula or butter knife to gently spread about half a tablespoon of peanut butter onto the white flesh side of each wedge.Try to make an even layer but do not overload,the peanut butter acts as edible glue for the teeth.
- Add Marshmallow Teeth:
- Align four mini marshmallows in a row on eight apple wedges Press each gently into the peanut butter so they stick securely.These become the monster’s teeth,space them out for crooked grins or line up neatly for a classic smile.
- Form the Monster Mouth:
- Take the remaining apple wedges and gently press them peanut butter side down onto the marshmallow row.Do not squeeze too hard or the peanut butter and marshmallows may squish out.You should now see the shape of a silly open mouth with marshmallow teeth inside.
- Decorate with Fangs and Eyes:
- If you like extra detail add sunflower seeds for pointy fangs by gently pressing into the apple’s “lip” edge To create eyes blob a tiny bit of peanut butter on top and affix one chocolate chip to each monster mouth.You can make single or double-eyed creatures.Have fun and let your imagination go wild.
- Serve and Enjoy:
- Arrange the monster mouths on a platter and serve immediately for crisp texture If you want to chill refrigerate for 10 minutes first so the peanut butter firms up and the apples stay fresh.

I always request my kids to pick out their favorite “eyes” using big chocolate chips or tiny ones.One year my youngest lined up spooky fangs on every mouth,we laughed for days about how our monsters all had braces.
Storage Tips
If you want to prep ahead dip apple wedges in lemon juice and wrap tightly to prevent browning.Once assembled store the mouths in a sealed container lined with parchment to keep them fresh up to 15 hours.These snacks are best eaten the same day for crisp apples and soft marshmallows.
Ingredient Substitutions
Trade red apples for granny smith if you like tartness.Sunflower seed butter is a great nut-free swap and works well for school or allergy-sensitive settings.Marshmallow teeth can be replaced with banana slices or dairy-free white chocolate morsels depending on your dietary needs.
Serving Suggestions
Lay monster mouths on a green lettuce bed or serve alongside orange segments for a Halloween color burst.For party platters add a variety,make some with “fangs” and others with “smiling” faces.Try serving with caramel dip for older kids or adults.

Apple Monster Mouths are guaranteed to spark giggles and creativity with every bite.Make these playful treats for your next party or holiday and let everyone build a monster masterpiece.
