Ingredients

  • 3/4 cup milk
  • 6 tablespoons (85g) butter
  • 2/3 cup sugar
  • 1 egg room temperature
  • 1 teaspoon vanilla extract
  • 2 tablespoons rye sourdough starter wheat starter works fine too
  • 1 1/4 cups (150g) whole ground rye flour
  • 1/2 cup (50g) hazelnut flour or almond flour slightly toasted is best
  • 1/2 cup raw cacao powder sifted
  • 1/2 teaspoon fine sea salt

Instructions

  • Combine 3/4 cup milk, 6 tablespoons butter and 2/3 cup sugar in a small sauce pan. Simmer until sugar melts. Allow to cool.
  • Whisk in an egg and 1 teaspoon vanilla extract.
  • Add 2 tablespoons rye sourdough starter, whisk until starter dissolves.
  • Add the rest of the ingredients, mix until no dry spots remain. The batter will be thick.
  • Cover and leave at room temperature for 8-10 hours. The batter doesn't change or rise much, the signs are airy and lighter look, and pockets of air when you scoop it.
  • When ready to bake, place batter into a greased pan (I'm using 6-cup small bundt pan). Preheat oven to 400ºF (in that order).
  • Bake for 30-35 minutes, or until internal temperature registers at 190ºF.

Notes

  • You can use 1.5 teaspoons of baking powder, if you want to make this cake but don't have a sourdough starter.
  • If you are wondering about milk and egg sitting out at room temperature, my take on it is there is a lot of enzymatic activity taking place during fermentation so I'm not worried about spoiling.
  • I think it's good enough on its own and doesn't really need a glaze. I used one for the photo, because well, it just looks cool, but normally we eat our rye sourdough cake without one.
