1 box (2-layer size) yellow cake mix
1 box (4-serving size) lemon gelatin
4 large eggs
1/2 cup canola oil
1 cup water
Beat all the ingredients together in a large mixer bowl; beat until well blended.
Grease and flour a 3-lb (metal) coffee can and pour the cake batter into the can. Place the can in the crockpot and place 4 thin or 6 thick paper towels over the top of the can. Put the lid on the cooker and cook on high 3 1/2 to 4 hours. Do Not Lift Lid and Peek until the last 30 minutes to hour of the cooking time.
Note: If using the larger 4 1/2-quart crockpot, cook 4 to 5 1/2 hours.
