I posted this on SS too but thought some of you that don't visit over there might like to try it. It is very good. I thought it would be great for lunchboxes or taking camping etc. My DH found the recipe in a Camp Cookbook. When they are done they are about the size of an individual cake or cup cake. 14 Step Canned Cake 1. Clean and ready your wide mouth half pint canning jars, lids, and rings. 2. Mix up any cake mix as per the instructions on the box. 3. Mix in something like M&M's or Mini Chocolate Chips to give the cake a little something extra. 4. Mix up a good icing- something gooey and sticky that will seep down the cake. 5. Fill jars about 1/3 to 1/2 full with the cake batter, it will rise as it bakes. 6. Place jars on a cookie sheet and bake 350 for 20-25 minutes. 7. Test cake with toothpick. 8. Remove from oven poke with a skewer or chop stick and frost immediately. Icing will seep into hole in cake. 9. If your cake has rose above the lip of the jar, just take a knife and trim the top leaving room for icing. 10. Carefully wipe the jar rims to be sure they are clean, be careful, they are very hot. 11. Place a lid and ring on each jar, tighten. Once again - be careful they are still very hot! 12. Allow jars to cool. You will hear them seal. 13. If any do not seal, set aside and have them after dinner tonight! 14. Make a cup of coffee or tea, sit in a comfy chair, and sample the cake! I could post a pic if anyone wants to see them.
