Hannah’s Most Dangerous Cake

Hannah in TallitAt Wimbledon Synagogue, there are great bakers and foodies of all ages, and we are really pleased to feature a cookbook written by Hannah O’Keeffe, aged 13, who had her batmitzvah in October at Wimbledon Synagogue. For her tzedakah project (carried out as part of her batmitzvah preparations focusing on the mitzvah of charity), she decided to write a cookbook called Baking with Hannah to raise money for her chosen charity. Here is why Hannah did it:

“I decided to put together a book with all the yummy things I love to make and to eat so that I could raise funds to support research into PANS/PANDAS.  Those are paediatric neurological syndromes that cause acute and debilitating symptoms and are extremely disruptive to the health and lives of children and their families, especially as they are often misdiagnosed and treatment is costly and frequently not covered by insurance.  My first cousin has PANS and it is really difficult for her, so I wanted to do something to help her and other children with this illness.  I am hoping lots of people will buy this cookbook and support my efforts on their behalf.  If you would like to find out more about PANS/PANDAS, or get an idea of the ongoing research, please have a look at http://pandasnetwork.org, which also serves the PANS community.”

Hannah has already sold a lot of copies of the book, but will be selling more at the Hanukkah Fair at the synagogue on 24th November (12-2pm) so please come along and find her. Or, if you can’t make the fair, you can order a copy (£10) by emailing wimshulcooks@gmail.com.

Hannah has kindly agreed to share one of the recipes from her cookbook: her “most dangerous cake”.

Most Dangerous Cake

Makes one chocolate mug cakeMost Dangerous cake (c) O'Keeffe


  • 4 tablespoons flour
  • 4 tablespoons sugar
  • 2 tablespoons cocoa
  • 1 egg
  • 3 tablespoons milk
  • 3 tablespoons oil
  • 3 tablespoons chocolate chips (optional)
  • a small splash of vanilla extract

1 large coffee mug (the bigger the better)


  1. Add the dry ingredients into the mug and mix well.
  2. Add the egg and mix thoroughly.
  3. Pour in the milk and oil and mix once again.
  4. Add the chocolate chips (if using) and vanilla extract and keep mixing.


  1. Place the mug into the microwave and cook for 3 minutes on high.
  2. The cake will probably rise over the top of the mug but don’t be too alarmed
  3. Allow to cool and tip on to plate if desired, then…eat!

Note from Hannah: “The reason for this being called the most dangerous cake recipe in the world is because now we are only ever 5 minutes away from chocolate cake at any time of day!  The recipe is from my Aunt and I tried it as soon as I saw it!”
