Ingredients for Monster Mouth Apple Slices
Here’s all you need to make these adorable monster mouths come to life:
- 2 medium apples (I prefer crisp varieties like Honeycrisp or Fuji), thinly sliced
- 1/4 cup creamy peanut butter (or almond butter for nut-free versions)
- 1/4 cup mini marshmallows (the tiny ones work best for cute little teeth!)
That’s it! Just three simple ingredients transform into the most fun snack ever. Pro tip: If your apples aren’t super fresh, give them a quick soak in lemon water to prevent browning.
How to Make Monster Mouth Apple Slices
Ready to turn ordinary apples into monster magic? Here’s how we do it in my kitchen (usually while dodging tiny hands trying to “help”):
- Slice your apples into about 8 wedges per apple—not too thin or they’ll break, not too thick or they won’t hold the toppings well. Remove seeds but leave the peel on for extra crunch!
- Spread peanut butter along the curved edge of each slice—this is your “glue.” I use about 1/2 teaspoon per slice and smush it slightly toward the center to make a lip-like shape.
- Press marshmallows into the peanut butter at staggered intervals to create jagged monster teeth. The mini ones work perfectly—just push gently until they stick but don’t flatten them completely.
- Chill (optional) for 10 minutes if you want the peanut butter to set, but honestly, we never wait that long before gobbling them up!
Tips for Perfect Monster Mouths
My trial-and-error lessons for flawless monster mouths:
- Lemon water soak (1 tbsp lemon juice + 1 cup water) keeps apples from browning if prepping ahead
- Dry apple slices well before spreading peanut butter—moisture makes the toppings slide off
- Press marshmallows firmly but not too deep—you want them to peek out like real teeth!
Ingredient Substitutions & Variations
The beauty of these monster mouths? You can totally customize them based on what you’ve got handy or dietary needs! Here’s how we mix it up:
- Nut-free? Sunflower seed butter or yogurt work beautifully as “glue” (though the marshmallows won’t stick quite as well—still delicious!)
- Extra spooky? Swap marshmallows for raisins or chocolate chips to create different monster expressions
- More crunch? Add slivered almonds along the edges for jagged “scary” teeth
My kids love when we make “monster families” with different toppings—gets them way more excited about eating their apples!
Serving & Storing Monster Mouth Apple Slices
These monster mouths are happiest when served right away—those marshmallow teeth start losing their crunch if they sit too long! If you must prep ahead (I get it—parent life), chill them for 10 minutes max to set the peanut butter. Just know leftovers get a little soggy, but my kids still devour them with zero complaints!
Nutritional Information for Monster Mouth Apple Slices
Here’s the tasty truth about these monster mouths (per serving):
- 120 calories
- 12g sugar (natural from apples + marshmallows)
- 3g protein (thanks to peanut butter power!)
Nutritional values are estimates and vary by ingredients. But honestly—when snacks are this fun AND wholesome, who’s counting?
Frequently Asked Questions
Can I make monster mouth apple slices ahead of time?
Yes, but they’re best fresh! If you must prep early, soak apple slices in lemon water (1 tbsp lemon juice + 1 cup water) for 5 minutes first to delay browning. Store assembled slices in an airtight container with paper towels to absorb moisture—they’ll last about 2 hours before getting soggy.
What if my kids can’t have nuts?
No problem! Sunflower seed butter works great, or try Greek yogurt (though marshmallows won’t stick as well). For school-safe versions, WowButter (soy-based) fools even my picky nephew!
Mini marshmallows too big?
Snip them in half with kitchen shears or use those tiny nonpareil sprinkles as “fangs.” Raisins make awesome creepy teeth too—my kids call those “vampire apples!”
