Instructions
Prepare the peanut‑butter base (both versions)
In a large mixing bowl, add the chunky peanut butter. Using the hand mixer on low speed, beat until smooth.
Time: PT2M
Add wet ingredients
Add the egg, vanilla extract, brown sugar, and baking powder to the bowl. Mix on medium speed until the mixture becomes a compact, homogeneous dough.
Time: PT3M
Form simple‑version cookie balls
For the easy version, scoop about 18 g (≈1 tablespoon) of dough, roll between your palms into smooth balls, and place on a parchment‑lined baking sheet, spacing them 2‑3 cm apart.
Time: PT5M
First bake (both versions)
Pre‑heat the oven to 160 °C (fan‑forced). Bake the cookies for 10‑12 minutes until the edges are set but the centers are still slightly soft.
Time: PT12M
Temperature: 160°C
Create a central well
Immediately after removing the cookies from the oven, use a small round piping tip or the back of a teaspoon to press a shallow well in the centre of each warm cookie. This will hold the chocolate “body” later.
Time: PT3M
Cool simple cookies
Transfer the cookies to a cooling rack and let them reach room temperature (about 15 minutes).
Time: PT15M
Prepare the sandier dough (second version)
In a clean bowl, cream together softened butter and peanut butter until light and fluffy. Add white sugar, brown sugar, and continue beating until the mixture turns pale and mousse‑like.
Time: PT5M
Add dry ingredients and egg
Add all‑purpose flour, baking powder, baking soda, salt, vanilla extract, and the egg. Mix on low speed until just combined, then finish with a spatula to form a compact dough.
Time: PT5M
Portion and chill
Divide the dough into 25‑gram portions (about 1 ½ tablespoons). Roll each portion into a smooth ball and place on a parchment‑lined sheet. Chill the balls in the refrigerator for 30 minutes.
Time: PT30M
Second bake – first round
Pre‑heat the oven to 175 °C (fan‑forced). Bake the chilled balls for 10‑12 minutes until the edges are lightly golden.
Time: PT12M
Temperature: 175°C
Create wells for spider bodies
While the cookies are still warm, press a shallow well in the centre of each using a rounded tip. Set aside to cool.
Time: PT3M
Second bake – finish
Lower the oven to 170 °C and bake the cookies an additional 4‑5 minutes to firm the edges and ensure the wells stay open.
Time: PT5M
Temperature: 170°C
Cool second‑version cookies
Transfer to a cooling rack and let cool completely (about 15 minutes).
Time: PT15M
Melt chocolates
Place dark chocolate pieces in a microwave‑safe bowl. Heat in 30‑second bursts, stirring between each, until smooth. Repeat with white chocolate. Let both meltings cool to room temperature (they should be fluid but not hot).
Time: PT5M
Fill piping bags
Transfer the dark chocolate to a piping bag fitted with a small round tip; do the same with white chocolate in a separate bag.
Time: PT2M
Assemble spider bodies (simple version)
Drop a small dollop of dark chocolate into the well of each simple cookie to form the spider’s abdomen. Place a Kit Kat piece (or chocolate wafer) on top as the head.
Time: PT5M
Add legs (simple version)
Using the dark‑chocolate piping bag, draw three short, parallel lines from each side of the cookie outward to create spider legs. For a sturdier look, draw a second set of lines slightly offset.
Time: PT5M
Assemble spider bodies (sandier version)
Fill each well with a small ball of dark chocolate (or a chocolate bar piece) for the abdomen, then place a Kit Kat piece on top as the head.
Time: PT5M
Add legs (sandier version)
Pipe dark chocolate lines from each side of the cookie to form eight legs (four per side). Let the chocolate set.
Time: PT5M
Finish eyes
Pipe tiny dots of white chocolate at the top of each head for eyes, then add a single dot of dark chocolate in the centre of each white dot to create pupils.
Time: PT5M
Set the decorations
Allow the cookies to sit at room temperature until the chocolate hardens (about 10 minutes) or place them briefly in the refrigerator to speed up setting.
Time: PT10M

Critical Steps — Do Not Skip
- Mixing the dough to a homogeneous, compact texture.
- Creating the central well while the cookie is still warm.
- Chilling the sandier dough for at least 30 minutes.
- Melted chocolate must be cooled to a workable temperature before piping.
Chef Tips from the Video
- Use a kitchen scale for precise dough portions; it ensures uniform cookie size.
- For extra crunch, sprinkle a pinch of sea salt on top of the dark‑chocolate abdomen before it sets.
- If you prefer a sweeter cookie, increase the brown sugar by 1‑2 tablespoons.
Troubleshooting
Cookies spread too much and become flat.
Chill the dough longer (at least 45 minutes) and use parchment paper to prevent sticking.
Chocolate legs sag or run.
Allow melted chocolate to cool to room temperature before piping; refrigerate cookies briefly before adding legs.
Wells close up before filling.
Create the well immediately after baking while the cookie is still warm; work quickly.
Storage
Refrigerator: Up to 5 days in an airtight container.
Freezer: Up to 2 months; thaw at room temperature before serving.
Room temperature: Best consumed within 2 days; keep in a sealed tin.
Make-Ahead Tips
- Bake the cookies up to step 6 and store them in an airtight container; add the chocolate decorations the day of serving.
- Chocolate can be melted in advance and kept in a warm water bath for easier piping.
