Baking cake in a canning jar might sound like a Pinterest stunt, but this one actually works.

A rich, cocoa-based brownie batter with buttermilk and chopped walnuts gets poured into sterilized wide-mouth pint jars and baked until a pick comes out clean.

Seal the lids on while the cakes are still screaming hot, and the jars vacuum-seal as they cool.

The result is a fudgy, portable brownie cake that makes an incredible homemade gift or a grab-and-go treat for picnics and lunchboxes.

Kitchen Tips

  • Use only straight-sided, wide-mouth canning jars. Tapered jars will trap the cake and make it impossible to remove.
  • Sterilize the jars, lids, and rings in boiling water for a full 10 minutes before filling.
  • Seal the lids immediately after pulling each jar from the oven. The heat creates the vacuum seal, so speed matters.
  • A pinch of cinnamon in the batter is optional but adds a warm depth that plays well with the cocoa.
