Instructions

Tips & Notes

  • Toast the hazelnuts at 350°F for 10-12 minutes and rub off the skins in a towel before grinding. Toasting is what gives the hazelnut chocolate cake its deep, nutty flavor.
  • Take the cake out while a toothpick still shows a few moist crumbs. A fully clean toothpick means the hazelnut chocolate cake will be dry.
  • Store the cake covered at room temperature for up to 3 days. The ground hazelnuts keep it moist, and it slices more cleanly on the second day.
