Make these spooky treats from chocolate and peanut spider sponges for a fun treat this Halloween. Fluffy chocolate sponge laced with crunchy peanut butter and topped with a chocolate, peanut treat and crunchy pretzel legs. Great for kids, these are sure to be a huge hit!

Preparation time: 5 minutes
Cooking time: 25 minutes


  • 120g unsalted butter, plus extra for greasing
  • 120g golden caster sugar
  • 1tsp vanilla extract
  • 100g self raising flour
  • 1tsp baking powder
  • 50g cocoa powder
  • 2 eggs
  • 1tbsp milk

To decorate

  • 300g chocolate spread
  • 6 Reeses cups
  • 12 edible eyes
  • 24 pretzels


Preheat your oven to 180°C/ 160°C Fan/ Gas Mark 4.

  1. In a bowl, cream together the butter, sugar and vanilla extract. In a separate bowl sieve together the flour, baking powder and cocoa powder.
  2. When the butter and sugar mixture is light and fluffy, crack in one of the eggs and add a tablespoon of the flour mixture. Whisk until the egg is well incorporated. Repeat again with the remaining two eggs.
  3. Once all the eggs are added, pour in the remaining flour along with the peanut butter and milk. Whisk until a smooth, thick batter forms.
  4. Take 6 ramekins (or petite casserole dishes) and grease with a little butter. Divide the cake batter between the ramekins, place on a baking tray and bake in the oven for 20-25 minutes until cooked through. Remove from the oven and allow to fully cool.
  5. To decorate, divide the chocolate spread between the cakes and smooth over the top of each using a palette knife. Stick one Reese’s cup in the middle of each iced cake and stick on two edible eyes using a little chocolate spread.
  6. Using pieces of pretzel, add 8 legs (4 either side) to the spider body and serve.

Cook’s Notes For These Spooky Treats

  • The sponges will release effortlessly from the ramekins; if you are making a larger batch of spider sponges but don’t have the number of ramekins, simply bake, turn out when cool to touch, wash and re-grease the ramekins. You can then bake the remaining batter.
  • Ensure you use plain or salted pretzels for these sweet treats.
