This is an awesome gift to give... Please read all instructions carefully. Prewash 8 pint-sized wide mouth canning jars (be sure to use the kind that have no shoulders) in hot, soapy water. Rinse well, dry and let them come to room temperature. Grease insides of jar well.Only use shortening, no sprays. Pour one cup of batter into each jar and carefully remove any batter from the rims. Place jars in a preheated 325-degree oven and bake for 40 minutes. While cakes are baking, bring a saucepan of water to a boil and carefully add jar lids. Remove pan from heat and keep lids hot until ready to use. When the cakes have finished baking, remove jars from oven. Make sure jar rims are clean. (If they're not, jars will not seal correctly) Place lids on jars, and screw rings on tightly. Jars will seal as they cool. Cakes will slide right out when ready to serve. **you can remove the rings after cooled/sealed and add decorations and labels.
