- ½ cup creamy peanut butter
- 1 large egg
- 1 tsp vanilla extract
- 1 ½ cups all-purpose flour
- ¾ tsp baking soda
- ¼ tsp baking powder
- ¼ tsp salt
Spider Decoration
- 24 chocolate truffles (Lindt or similar) for spider bodies
- ½ cup semi-sweet chocolate chips (for legs)

Instructions
1. Make the Dough
- Preheat oven to 350°F (175°C).

2. Shape and Bake
- Scoop dough into 1-inch balls and roll lightly in sugar.
- Place on parchment-lined baking sheet, spaced 2 inches apart.
- Bake 10–12 minutes, until edges are golden and centers puffed but soft.
- Remove and cool 3 minutes — they’ll firm up as they cool.
💡 Tip: Don’t overbake! You want a soft, chewy center for the perfect bite.
3. Add the Spider Bodies
- While cookies are still warm, press a chocolate truffle into the center of each.
- Let cookies cool completely so the truffles set.
4. Create the Spider Legs
- Melt chocolate chips in the microwave (20-second bursts).
- Transfer melted chocolate to a piping bag or zip-top bag with tip cut off.
- Pipe 4 legs on each side of the truffle — thin, curved lines.

FAQs (PAA Section)
How to know if peanut butter cookies are ready?
They’re ready when the edges are slightly golden and the tops start to crack but still look soft. They’ll continue to firm as they cool. Overbaking makes them dry.
What is a fun fact about peanut butter cookies?
The famous crisscross fork pattern was first published in 1932 to help peanut butter cookies bake evenly. In this version, we skip it — our “spiders” take the spotlight!

How to store spider cookies?
Keep in an airtight container layered with parchment. For parties, refrigerate them and bring to room temp before serving. Avoid stacking until chocolate legs are fully set.
Do peanut butter cookies need to be refrigerated?
Not required, but recommended for longer freshness. Store at room temp up to 4 days, or refrigerate for 7. Chilling also helps preserve chocolate decorations.
