This tower cake is perfect for Halloween! Feel free to make this with little ones; they'll have a great time adding the web design made out of the melted vegan marshmallows. Be careful though and wear gloves; the marshmallows are hot!

If you’re a kid, get an adult helper! This is a tricky one.
  1. Firstly, you'll need three 4-inch cake tins. Lightly grease the tins with some vegetable oil. Roll out your baking paper and trace around your cake tins three times.
  2. Cut out squares and place on the bottom of your tins. Cut out 4 other squares that are a little longer for each side of the cake tin and put them on the sides of your cake tin. They should overlap at the top.
  3. Melt your coconut oil in a small bowl in the microwave or in a small pan on the stove and then stir in cocoa powder.
  4. Grab another small bowl, melt chocolate in short bursts in the microwave or on the stove using a double boiler method.
  5. In a large mixing bowl, pour in chocolate and oil and mix together. Add icing sugar and mix well.
  6. Add puffed rice and stir through until all rice bubbles are coated in chocolate.
  7. Fill each cake tin evenly with puffed rice and push down using the flat bottom of a glass. Try and make them as even as possible.
  8. Place in fridge for about 1 hour or until set.
  9. Remove from fridge and pull on the baking paper to release each cake from the tin.
  10. Using a serrated knife, gently level the top of any little bumps so it’s perfectly flat.
  11. Melt a small amount of chocolate and glue each layer together to create a tall tower and place on your cake board or stand.
  12. Put back in the fridge to set.
  13. Once set, remove from the fridge. In a small heatproof bowl, melt 1/2 cup marshmallow in 10-second intervals in the microwave, until it’s very melted and gooey.
  14. Let it set for about a minute.
  15. Make sure you are VERY careful as it’s going to be hot. Make sure you’re wearing food-safe rubber gloves and that you test the temperature of the marshmallow BEFORE you pick up a large amount of it. Press the marshmallow between your hands and then pull it apart to create web strings.
  16. Wrap these strings around your cake to create a spider web. You need to do this quickly before the marshmallow sets. Repeat the process until you have covered your cake in spider webs. It may take a little practice.
  17. Add your toy spiders and you’re finished!
