  • Add the vanilla, beat for 30 seconds to combine.
  • Alternately add the flour and milk to the bowl in two batches and mix until just combined. Do the last little bit with a spatula to avoid over mixing.

Ganache (Optional)

  • Heat the cream until simmering, pour over the chocolate and mix well. If it doesn't melt the chocolate after a little stirring then microwave for 20 seconds to help the process along.

Notes

  • I use dutch cocoa because that's what is commonly available in Canada, but this works with regular too 
  • reducing the sugar will reduce the moisture in the cake so please check on it a little earlier if you choose to do so!
  • this cake doesn't need a ganache, but I often get asked for how to make it so I've included that here as optional
