Halloween Apple Monster Mouth
A tray of monster mouthes made from apples and peanut butter. A spooky snack and fun Halloween fruit tray addition.
These festive and tasty Monster Mouth snacks are awesome alongside Zombie Fingers or a Brain Cheeseball for a fun Halloween spread.
One of the things I really wanted to accomplish with the Halloween Food series I am doing is having fun and spending time with my kiddos.
I let them make these, and boy did we ever have a blast.
I even grabbed some cool Wilton Halloween Spider Sprinkles off of Amazon that they could put in the peanut butter so that it looks like these monsters have spiders in their mouth. It was so much fun. I hope you too can have fun making these!
Here are some tips for preventing apple slices from browning:
- Use Lemon Juice:
- Toss the apple slices in a bowl with a few tablespoons of lemon juice. The citric acid in the lemon juice slows down the oxidation process, keeping the slices looking fresh.
- Soak in Salt Water:
- Mix 1/2 teaspoon of salt with a cup of cold water and soak the apple slices for about 5 minutes. Rinse them with fresh water before serving to remove any salty taste. The salt helps to inhibit browning.
- Use Honey Water:
- Combine 2 tablespoons of honey with a cup of water and soak the apple slices for 5-10 minutes. Honey has natural enzymes that prevent browning.
- Coat with Fruit Juice:
- Toss the apple slices in fruit juices like orange, pineapple, or lime juice. These juices not only add flavor but also have acids that slow down browning.
- Wrap in Plastic or Use an Airtight Container:
- If you’re prepping apple slices ahead of time, store them in an airtight container or wrap them tightly in plastic wrap. Limiting their exposure to air helps reduce browning.
- Use an Anti-Browning Product:
- Products likeFruit-Fresh® contain ascorbic acid (vitamin C) and can be sprinkled over the apple slices to keep them fresh.
- Refrigerate Immediately:
- Keep the apple slices cold by refrigerating them right after slicing. The lower temperature slows down the browning process.
- Soak in Club Soda:
- Submerge apple slices in club soda for a few minutes. The carbonation helps prevent browning without affecting the flavor.
How to Make Monster Mouthes with Apple Slices
Here’s how to make monster mouths using apple slices, peanut butter, sesame seeds for teeth, strawberry slices for a tongue, and candy eyes:
Ingredients:
- Apples (any variety)
- Peanut butter
- Sesame seeds
- Strawberries
- Candy eyes
Instructions:
- Prepare the Apples:
- Wash and dry the apples thoroughly.
- Cut the apples into quarters and then into thinner slices. Each quarter should give you two or three slices, depending on the size of the apple. These slices will serve as the “lips” of your monster mouth.
- Add the Peanut Butter:
- Spread a thin layer of peanut butter on one side of each apple slice. This will act as the “glue” to hold everything together.
- Create the Monster Mouth:
- Take two apple slices and place them together, peanut butter side facing inwards, with a gap between them for the “mouth.”
- Press down gently to secure the slices together.
- Add the Teeth:
- Stick sesame seeds into the peanut butter along the edge of the mouth, spacing them out to resemble teeth. You can make them look crooked or uneven for a more monstrous effect.
- Make the Tongue:
- Slice a strawberry into thin, flat pieces.
- Place a slice of strawberry inside the “mouth,” allowing part of it to stick out to resemble a tongue.
- Finish with Eyes:
- Place a small dab of peanut butter on the top of the apple slices and attach the candy eyes. You can add one, two, or even more eyes to create different expressions for your monsters.
Serve:
- Arrange the monster mouths on a plate and enjoy these spooky, healthy, and fun treats! They’re perfect for Halloween or any time you want to add a little creativity to snack time.
This is the book we read:Monster Needs a Costume (Monster & Me)
It is such a cute book. It is about a monster who is trying to decide what to be for Halloween. It perfectly addresses the challenge of choosing a Halloween costume, and is beautifully illustrated. I thoroughly enjoyed it, which is good since my little one wanted to read it a gazillion times.
