Cakes in a Jar

"These individual cakes are baked and served right in the jar. Layers of sweet fruit and cobbler-esque cake fill Mason jars for the ultimate portable picnic dessert. Karen came up with this recipe in the summer, but she recommends using whatever fruit is in season; she also says this recipe is a good use for slightly damaged fruit. Game plan: These cakes can be made ahead; stored (with a proper lid and sans whipped cream) in the refrigerator for up to 1 week; and, of course, gifted. Watch Karen demonstrate how to make her single-serving cakes in this CHOW Tip video...."
