These Poison Apple Caramel Apples are fun and spooky treats for any party! Juicy apples are dipped in creamy caramel and covered with green chocolate for that creepy touch.
They look just like a witch’s favorite snack! I love making these with the kids—they are so excited to help dip and decorate. Plus, they make great Halloween gifts!
Key Ingredients & Substitutions
Granny Smith Apples: These tart apples are ideal for caramel apples, providing a nice tartness that balances the sweetness of the caramel. If you don’t have them, any tart apple like Fuji or Honeycrisp works as well!
Granulated Sugar: This is crucial for making the caramel. If you want to reduce sweetness, you could try using coconut sugar, but the texture might change slightly. Brown sugar can also add a rich flavor but will change the color and sweetness.
Corn Syrup: Corn syrup helps prevent the sugar from crystallizing, giving a smooth caramel. If you’re avoiding corn syrup, you can replace it with golden syrup or a mix of honey and water, but the texture could be a bit different.
Food Coloring: The food coloring gives the apples that spooky, poison touch. If you prefer natural ingredients, use beet juice for red or activated charcoal for black, though the shades may vary slightly.
Rock Candy or Edible Glitter: For decoration, crushed rock candy adds a fun crunch. Edible glitter can elevate the presentation. You can use crushed nuts or sesame seeds if you’re looking for alternatives!
How Can I Make Sure My Caramel is Perfectly Cooked?
Getting the caramel to the right temperature is key for a good texture. Using a candy thermometer is the best way to ensure you’re hitting that hard crack stage at 300°F. Here’s how to do it right:
- Combine sugar, corn syrup, and water in a medium saucepan over medium heat, stirring until dissolved.
- Once dissolved, let it boil without stirring. It’s essential not to mix once it starts boiling, as this can cause crystallization.
- Keep an eye on the thermometer and remove it from heat immediately once it reaches 300°F. It can burn quickly if left too long!
- Add in the apple cider vinegar and vanilla extract right away after taking it off the heat; this adds flavor and helps with the consistency.
With these tips in hand, you’ll have perfectly caramel-coated apples ready to impress! Enjoy the festive treat!

How to Make Poison Apple Caramel Apples
Ingredients You’ll Need:
For the Apples:
- 6 medium Granny Smith apples (or other tart green apples), washed and dried
- 6 wooden sticks or decorative straws for handles
For the Caramel Coating:
- 2 cups granulated sugar
- 1 cup light corn syrup
- 3/4 cup water
- 1/2 teaspoon cream of tartar
- 1/2 teaspoon red or black food coloring (optional, for a dark “poison” color)
- 1 teaspoon apple cider vinegar
- 1 teaspoon vanilla extract
For Decoration:
- Crushed green rock candy or edible glitter
Time Needed:
This treat will take about 15-20 minutes to prepare, plus an additional 30 minutes to let the caramel harden. Just grab your ingredients and let’s get started making these spooky treats!
Step-by-Step Instructions:
1. Prepare the Apples:
Start by firmly inserting a wooden stick into the stem end of each apple. This will serve as your handle, so make sure it’s secure. Once done, set the apples aside on a baking sheet lined with parchment paper, ready for dipping.
2. Combine Ingredients for Caramel:
In a medium saucepan, combine the granulated sugar, corn syrup, water, and cream of tartar. Stir gently over medium heat until the sugar is fully dissolved. Be patient—you want it to mix well!
3. Boil the Mixture:
Attach a candy thermometer to the side of the saucepan. Allow the mixture to boil without stirring until it reaches 300°F (this is called the hard crack stage). Keep an eye on it and don’t leave it unattended; it can burn quickly!
4. Add Flavor and Color:
As soon as the caramel reaches 300°F, remove it from the heat. Carefully stir in the apple cider vinegar and vanilla extract. If you want that eerie poison color, add in the food coloring a few drops at a time until you reach your desired shade.
5. Dip the Apples:
Working quickly but carefully, dip each apple into the caramel, swirling to coat it completely. Allow the excess caramel to drip back into the pan. The coating should be thick and glossy!
6. Decorate and Cool:
Place the caramel-dipped apples onto the parchment-lined tray. While they are still sticky, sprinkle crushed green rock candy or edible glitter around the top edges to give them that magical, toxic look. Let the apples sit at room temperature for about 30 minutes to harden.
7. Serve and Enjoy!
If you’d like, chill the apples briefly for a firmer candy shell before serving. Present them on a platter for a fun and spooky treat! Perfect for Halloween parties or any eerie occasion!
Enjoy your deliciously spooky Poison Apple Caramel Apples! They’re sure to be a hit!

Can I Use Different Types of Apples?
Yes, while Granny Smith apples work best due to their tartness balancing the sweetness of the caramel, you can use other tart apples like Fuji or Honeycrisp as well!
What Can I Use Instead of Corn Syrup?
If you want to avoid corn syrup, you can try using golden syrup or a mix of honey and water. Just note that this may slightly alter the texture and flavor.
How Do I Store Leftover Caramel Apples?
Store any leftover apples in an airtight container at room temperature for up to 3 days. Avoid refrigerating as this may cause the caramel to become sticky!
Can I Make These Ahead of Time?
Absolutely! You can prepare the apples and caramel in advance. Just be sure to decorate them right before serving for the best presentation and texture.
