We might not be able to go back to those times but this Hermione Sweet Sourdough Apple Coffee Cake can at least help you imagine it with each bite you savour.

Hermione Sweet Sourdough Apple Coffee Cake

Time: 45 minutes

Yield: 12 – 15 large squares

Equipment: Stand Mixer, 7×11-inch baking pan


  • For the Cake:
  • ¾ cup sugar
  • ⅓ cup oil
  • 1 egg
  • 1 cup sourdough
  • ½ teaspoon vanilla
  • 1 cup chopped apple
  • 1 cup all-purpose flour
  • 1 teaspoon cinnamon
  • ½ teaspoon salt
  • ¾ teaspoon baking soda
  • For the Topping:
  • 1 teaspoon cinnamon
  • 2 Tablespoons butter
  • 1 Tablespoon flour
  • 1/4 cup brown sugar

  1. Preheat the oven at 350℉ and butter the baking pan.
  2. Place the sugar and oil in the bowl of a stand mixer and beat until light and fluffy. Add the egg and beat again, then add the sourdough and vanilla and beat on low speed just until combined.
  3. Add the flour, cinnamon, salt and baking soda and beat until combined.
  4. Fold in the apple pieces.
  5. Pour into a buttered 7×11-inch baking pan.
  6. Use your hands to combine the cinnamon, butter, flour and brown sugar in a bowl until crumbly. Sprinkle over the cake batter.
  7. Place the cake on the center rack in the oven and bake for 35 minutes or until golden and a toothpick inserted in the center comes out clean. Remove from the oven and cool in the pan on a wire rack.
  8. Enjoy, still warm if you can, with fresh whip cream and coffee (or tea – it’s okay, you can serve coffee cake with tea!)
