S'more Cake

Lightly coat a 6-quart oval slow cooker* with cooking spray. In a large bowl whisk together eggs, sour cream, and water. Add cake mix, flour, and sugar and stir until just combined. Stir in marshmallows. Spoon into prepared cooker. Cover and cook on low for 3 to 4 hours or until internal temperature reaches 165ºF. Cake will be wet just in the center.

Drop spoonfuls of marshmallow creme over hot cake (it will spread to an even layer as it stands). Sprinkle with milk chocolate and graham cracker pieces. Remove crockery liner from cooker. Let stand, covered, for 15 minutes. Uncover and let stand 15 minutes more. Serve with a spoon.
