2. Pour 80.89ml of intrusive thoughts in and mix well.
3. Add a teaspoon of checking behaviours and a tablespoon of paranoia and stir.
4. Pour into a baking tin and heat at 10,003 degrees Celsius in an oven.

For the icing:

1. Combine four heaped teaspoons of guilt with 103.5ml of anxiety.
2. Once cooled, spread the icing evenly across the OCD cake.
