Easy coffee cake made with crisp apples and dark chocolate.



  • 5 eggs
  • 1½ cups packed brown sugar
  • 1 cup vegetable oil, plus 1 tablespoon for the baking pan
  • 2 cups unbleached, all-purpose flour
  • 1 tablespoon cinnamon
  • 1 teaspoon baking soda
  • 3½ ounces dark chocolate (about one chocolate bar)
  • 4 cups firm, peeled apples cut into ½-inch cubes (about 2 large or 3 medium apples)
  • Powdered sugar for dusting


  1. Preheat the oven to 350 degrees and brush a rimmed, 9×13-inch baking pan with 1 tablespoon of the vegetable oil.
  2. In a large bowl, beat the eggs and mix in the sugar. Stir in the oil and add the flour, cinnamon, baking soda, chocolate and apples. Mix until combined.
  3. Pour the batter into the baking pan and spread evenly. Bake in the oven until a knife or cake tester inserted in the middle comes out clean, about 35–40 minutes.
  4. Let cool completely in the pan, and then slice. Dust with powdered sugar. The cake will keep in a cool place, tightly wrapped, for up to 3 days.


  • Add 3/4 cup chopped walnuts or pecans to the batter in step 2.
  • I used olive oil instead of vegetable oil a few times and didn’t taste a difference.
