You won’t believe how simple it is to make a moist, flavorful German chocolate cake right in your slow cooker. With minimal prep and no fuss, this method yields a rich, tender cake every time.

Using a crockpot to bake a cake is a great shortcut, and starting with a boxed mix makes it even easier. A standard 13.25-oz cake mix fits nicely in a 6-quart oval slow cooker, producing a consistently moist cake with classic flavor.

German chocolate cake is beloved for its combination of chocolate cake and the signature coconut-pecan topping. The cake itself has a gentle chocolate note, while the coconut pecan frosting provides the rich, gooey contrast that makes this dessert so memorable. Using a good store-bought frosting saves time without sacrificing taste.

What you Need:

Ingredients for slow cooker German chocolate cake on a table.
  • Cake mix: 13.25-oz German chocolate cake mix (or any chocolate cake mix if preferred).
  • Standard mix-ins: Ingredients called for on the box—typically eggs, oil, and water. Add 1 tsp vanilla extract to boost flavor.
  • Coconut pecan frosting: A 15.25-oz tub of coconut-pecan frosting (store-bought or homemade) for that classic finish.

Variations

  • Swap in any chocolate cake mix if you don’t have German chocolate mix on hand.
  • Fold chopped pecans into the batter or sprinkle them on the frosting for extra texture.
  • Make your own coconut-pecan frosting if you prefer a homemade topping.

  1. In a medium bowl, combine the cake mix with the water, oil, eggs, and vanilla. Stir until the batter is smooth.
  2. Spray a 6‑quart oval slow cooker with nonstick spray and pour in the batter, spreading it evenly.
  3. Cover and cook on HIGH for 2 hours and 15 minutes. Keep the lid on for the entire cooking time; check near the end by looking through the lid. The cake is done when the center no longer jiggles.
  4. Carefully remove the stoneware insert and place it on a cooling rack. Let the cake cool for at least 2 hours.
  5. When the cake is completely cool, spread the coconut‑pecan frosting over the top. Slice and serve.

How to Serve

  • Serve the cake at room temperature or chilled; avoid serving it warm so the frosting stays set.
  • This cake pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream.

Recipe FAQs

Can I use a slow cooker liner?

Yes. A liner makes it easy to lift the cooled cake from the insert for quick serving and cleanup.

Can I double this recipe?

No. Doubling the batter in the same slow cooker will likely result in an undercooked center while the edges overcook. Use a larger cooker or make two batches instead.
