1. Blitz the oats in a high speed blender until ground to a flour.
2. Tip into a bowl and add the maple syrup, peanut butter, cinnamon, salt and vanilla extract. Mix until the mixture clumps together, adding a little water if needed. Mix in the chocolate pieces.
3. Divide the dough into 8, and roll each portion into a ball. Transfer to a baking paper lined tray, and gently press down to flatten slightly.
4. Melt the dark chocolate melts. Take one of the cookie dough balls and use a spoon to spread melted chocolate over the top and sides. It should set almost immediately. Place back on your tray, chocolate-size down. Repeat with remaining cookie dough balls, then repeat with the other side. These are your spiders’ bodies!
5. To make the legs, fill a zip-lock bag with 3-4 tbsp of melted chocolate (reheat if necessary) and snip a tiny hole at the corner. Pipe 5cm long arches onto a piece of baking paper - you’ll need 8 legs per spider, plus a few extra to allow for breakages.
6. Pipe little dots in the middle of each white chocolate drop to make eyes!
7. Reheat any remaining chocolate. Attach the legs by dipping one end into the melted chocolate, and holding against the side of the spider’s body until the chocolate has set. Attach 4 legs to each side of each spider body.
8. Dip the underside of each white chocolate eye in dark chocolate, before attaching two to the front top side of each spider.
