Makes 2 pint-sized jar cakes
Author Wendy Sondov


  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • ½ teaspoon baking soda
  • ¼ teaspoon cinnamon
  • 1 teaspoon espresso powder optional
  • 1/3 cup unsalted butter
  • ¼ cup water
  • 3 tablespoons cocoa I prefer Dutch processed for richer chocolate flavor
  • ¼ cup buttermilk
  • 1 egg
  • ½ teaspoon vanilla extract
  • 2 tablespoons mini chocolate chips


  1. Preheat the oven to 325 degrees F.
  2. Place two 1 pint canning jars (preferably wide mouth), lids, and rings in large sauce pan filled with water. Boil for 10 minutes. Carefully remove jars and dry thoroughly. Leave the lids and rings in the water to keep warm until needed.
  3. Coat the inside of each jar with non-stick spray. Place on a baking pan with sides. ( I used my jelly roll pan but a cake pan would be fine.)
  4. In a bowl, whisk together the flour, sugar, baking, soda, cinnamon, and espresso powder (if using).
  5. Combine butter, water and cocoa powder in a medium saucepan over medium heat. Stir constantly until the butter is melted and blended with the water and cocoa. Pour into a large bowl.
  6. Add the flour mixture to the cocoa mixture and stir to combine.
  7. Stir in the buttermilk, egg, and vanilla until blended. Mix in the mini chips.
  8. Divide the batter between the two prepared jars (approximately 1 cup in each). Wipe off any batter that gets on the sides or rim of the jars.
  9. Replace the jars on the baking pan (not touching each other). Bake for 35-40 minutes. Top of cake should spring back when touched. A wooden skewer can be used to test for doneness.
  10. Remove the pan with jars from the oven. Carefully (the jars are HOT) wipe off any baked-on batter or crumbs from the rims of the jars. Place a lid and ring on each jar and screw on firmly. Lids should “click” sealed in about 15 minutes.

Packing Tips

Make sure to wrap each jar individually in bubble wrap and place inside a well padded box. Pay special attention to padding the top, bottom and sides of the mailing carton
