These 3-ingredient monster mouth apples are the kind of playful no-cook party snack that earns a spot in the October rotation year after year. Crisp green apple wedges become silly little “mouths” with a swipe of peanut butter and mini marshmallows for teeth, creating a treat that is equal parts spooky, sweet, and kid-friendly. They are especially handy when you want something festive that comes together fast and doesn’t require baking, special equipment, or much cleanup.
Serve these monster mouths on a platter with other easy Halloween snacks like clementine pumpkins, pretzel sticks, popcorn, or cheese cubes. They also pair nicely with caramel dip, chocolate milk, apple cider, or a bowl of grapes and berries if you want to round out a party table with a few fresher options.
3-Ingredient Monster Mouth Apples
Servings: 6
Ingredients
3 green apples, cored and cut into wedges
1/2 cup peanut butter
1 cup mini marshmallows
Directions
1. Wash and dry the apples, then core them and cut them into wedges that are thick enough to hold their shape.
2. Spread a small layer of peanut butter on one cut side of an apple wedge and another small layer on a second wedge.
3. Press mini marshmallows into the peanut butter on one wedge to make the teeth, then top with the second wedge to form a monster mouth.
4. Repeat with the remaining apple wedges, then arrange the monster mouths on a plate and serve right away.
Variations & Tips
Use lemon water: If you are prepping the apples a little ahead, toss or brush the cut sides lightly with lemon water to slow browning. Dry them well before adding the peanut butter so the filling sticks properly.
Nut-free version: Swap the peanut butter for sunflower seed butter if you need a school-safe or nut-free option. It gives the same sticky effect and still holds the marshmallow “teeth” nicely.
Add candy eyes: For a more animated look, press a couple of candy eyes into the peanut butter near the top edge or set them on the plate beside each mouth. It takes only a minute and makes the tray even more party-ready.
Cut for easier eating: If serving younger kids, make slightly smaller wedges so each monster mouth is easier to bite into. Firm, tart green apples work best because they stay crisp and provide a nice contrast to the sweet filling.
