  • 1 box Betty Crocker™ Delights Super Moist™ German Chocolate Cake Mix
  • 1 1/4 cups water
  • 1/2 cup vegetable oil
  • 3 eggs
  • 6 tablespoons unsalted butter, softened
  • 2/3 of a 14 oz can of sweetened condensed milk, divided
  • 1 (11 ounce) package caramel bits
  • 1 tub (16 oz) Betty Crocker™ Rich & Creamy Milk Chocolate Frosting
  • 1/2 cup storebought caramel sauce
  • 1 cup pecan halves


  • 1
    Spray the inside of a slow cooker with cooking spray. Line the inside with foil, then spray the foil.
  • 2
    In a large bowl, beat together cake mix, water, oil, eggs, butter and 1/3 can of sweetened condensed milk on low speed 30 seconds, then on medium speed for 2 minutes, scraping bowl occasionally.
  • 3
    Pour half of the cake batter into the bottom of prepared slow cooker. Cover and turn on HIGH. Bake 1 1/2 hours or until cake is just set.
  • 4
    In a medium bowl, combine caramel bits and another 1/3 can of sweetened condensed milk. (Reserve remaining 1/3 of the can for another use.) Microwave for 2 to 3 minutes, then stir to melt caramel bits. Pour about 2/3 of the caramel mixture on top of the cake in the slow cooker, then pour remaining cake batter on top. Cover and cook on HIGH another 1 to 1 1/2 hours, or until a toothpick inserted in the top cake comes out mostly clean.
  • 5
    Remove stoneware insert and transfer to a cooling rack; cool cake 15 minutes in insert.
  • 6
    Carefully lift cake from the insert using foil as handles and place on cooling rack. Carefully remove foil from sides of cake.

    Place a serving plate upside-down on top of cake. Carefully and quickly invert cake onto serving plate. Cool completely.
