In large bowl, stir Cake ingredients until blended. Pour into slow cooker. Place folded, clean dish towel under cover of cooker. This will prevent condensation from dripping down onto cake. Cook on High heat setting 1 hour. Carefully remove slow cooker’s ceramic insert, and rotate insert 180 degrees. Sprinkle topping over cake. Replace cover with dish towel under the cover. Continue to cook on High heat setting 30 minutes to 1 hour or until toothpick inserted in center comes out clean.
