Apple Monster Mouths with Peanut Butter & Marshmallow Teeth – healthy Halloween snack for kids

Alright, friends, you know those moments when you want to feed your kids something fun, festive, but also (bonus!) a little healthy? Enter these Apple Monster Mouths—bite-sized, colorful, and just a little bit silly. When I first made these, the whole kitchen filled with the sweet smell of fresh apples and nutty peanut butter, and my kids couldn’t stop giggling as they “bit” into those marshmallow teeth. They’re perfect for Halloween parties, and honestly, any snack time that needs a little monster magic. Plus, they’re super simple to throw together, which means more time for fun and less time stuck peeling stickers off the counter!

Quick Facts

• Yield: Serves 6
• Prep Time: 15 minutes
• Cook Time: 0 minutes
• Total Time: 15 minutes

Ingredients

For the Main Dish:

• 2 large apples (red or green, your choice), cored and sliced into 1/2-inch thick wedges
• 1/2 cup creamy peanut butter (or any nut/seed butter you prefer)
• 12 large marshmallows
• 12 mini chocolate chips (for the “cavities” on the marshmallow teeth)

How I Make It

Step 1:

Start by slicing your apples into wedges—these will be the “lips” of your monster mouths. Make sure to core them first so they’re easy to bite into and not too seedy. I like using a mix of red and green apples because it makes the mouths look extra spooky and colorful.

Step 2:

Next, grab your peanut butter and spread a generous dollop on one apple wedge. Don’t be shy—this acts as the glue for the marshmallow teeth and adds that nutty flavor that pairs perfectly with the apple crunch.

Step 3:

Press the other apple wedge gently on top of the peanut butter-slathered slice to create a mouth shape. Now it’s time to add the teeth!

Step 4:

Cut each large marshmallow in half lengthwise to create flat “teeth.” Use a dab of peanut butter on the back of each marshmallow half and stick them along the top edge of the bottom apple slice, spacing them like chunky monster teeth.

Step 5:

Carefully press mini chocolate chips onto each marshmallow tooth to resemble little “cavities” or molars—this gives your monsters a fun, silly look.

Step 6:

Serve immediately for the best crunch! If making ahead, keep the apple slices separate and assemble just before serving to avoid browning.

Variations & Tips

• Switch out peanut butter for sunflower seed butter or almond butter for nut-free or flavor changes.
• Try using crunchy peanut butter for added texture.
• Use mini pretzel sticks as “fangs” instead of marshmallows for a less sweet option.
• Add a smear of cream cheese under the peanut butter for a tangy twist.
• Sprinkle a pinch of cinnamon on the apples before assembling for a cozy flavor boost.
• If marshmallows aren’t your thing, small sliced strawberries or banana pieces make great “teeth” too.

How I Like to Serve It

These Apple Monster Mouths are perfect on a Halloween party platter with other festive snacks like pumpkin hummus and veggie sticks. They also make a fantastic after-school treat that feels like a special reward but sneaks in fruit and protein. For a party, line them up on a spooky-themed tray sprinkled with candy eyes and edible glitter for an extra wow factor!

Notes

• To keep apple slices from browning, dip them in lemon water for a couple minutes before assembling.
• Best served fresh—apples get soggy and marshmallows get sticky if left out too long.

Closing: These monster mouths always bring smiles and crunch, making snack time feel festive and fun without any fuss.
