How to make spooky spider cookies
Making those cute little spooky spiders is super easy. First you have to bake the cookie and then you simply decorate it.
Make the cookie
Preheat your oven to 180°C (150°F).
Bake the cookies according to the instructions in my peanut butter cookie recipe.
Once you removed them from the oven let them cool for 5 minutes.
While they cool you can unwrap your Reese's.
Press 1 peanut butter cup upside-down into the center of each cookie.
Quickly move your cookies to a cold space. I usually put them in the fridge. If you do have the option then transfer them into your freezer and freeze them for about 15 minutes. The cooling process will avoid the Reese's from completely melting.
Decorate the cookie
Melt your chocolate in a water bath or as instructed on the package.
Add the melted chocolate to a piping bag and pipe little legs onto your Reese's starting at the peanut butter cup.
Next pipe some chocolate onto the Reese's and push the eyes in.
Let the chocolate set by putting the cookies into your fridge.
Make your own spider eyes
Candy eyes are not available everywhere. I myself could not find any in my area. As a solution I simply made my own spider eyes using simple ingredients.
To make your own eyes you will need:
- White chocolate
- Dark chocolate
- Piping bag (if possible one specifically made for chocolate like this one)
- Small nozzle
- Toothpick
Recipe notes
Double Batches: You can easily double this recipe. However, as it is much more cookie dough you will have to chill it longer (I recommend an extra 30 minutes).
Make Ahead Instructions: If you ask yourself if you can make the cookies ahead of time then I am happy to tell you you can! Here is how:
Make the cookie dough and let it rest in the fridge covered for up to 4 days. Once you are ready to bake the cookies remove the dough 30 minutes before hand.
Chefs tip: Form the cookie balls and freeze them. It is always great having cookie dough ready! There is no need to thaw the cookie dough. Bake the frozen cookies for an extra minute in the oven. The cookie dough can be frozen for up to 3 months.
Storage
Keep the finished and decorated cookies in a closed container for up to one week. After one week they start to get dry. It is recommended to keep them in the fridge if it is rather warm in your house as the chocolate might melt.
You can also freeze your cookies and simply let them thaw once you want to eat them.
Frequently asked questions
Q: Can I use other peanut butter cups instead of Reese's?
A: Yes, you absolutely can use other peanut butter cups. Just choose your favorite one. Make sure you get the mini version tough.
