Ingredients
For the Chocolate Cake
- 1½ cups all-purpose flour
- ¾ cup granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 2 large eggs, at room temperature
- ½ cup unsalted butter, melted and slightly cooled
- 2 teaspoons vanilla extract
- ½ cup hot water or hot brewed coffee
- ½ cup semisweet chocolate chips, optional
For the Optional Chocolate Ganache
- ½ cup semisweet chocolate chips
- ¼ cup heavy cream
Instructions
- Lightly grease the inside of your slow cooker with butter or nonstick cooking spray. If your appliance allows it, line the base with parchment paper for easier removal. Keep the paper clear of the heating elements and away from the lid seal.
- In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Break up any cocoa lumps so the dry ingredients are evenly distributed.
- In another bowl, whisk the eggs, milk, melted butter, and vanilla extract until smooth. Make sure the butter is not too hot before adding the eggs.
- Pour the wet mixture into the dry ingredients. Stir gently until the flour is incorporated and no large dry patches remain. Avoid overmixing, which can make the cake dense.
- Gradually stir in the hot water or hot brewed coffee. The batter will become thinner than conventional cake batter; this is normal and helps create a moist cake.If desired, fold in the chocolate chips for extra chocolate flavor.
- Pour the batter into the prepared slow cooker and spread it evenly with a spatula. Avoid filling the appliance more than halfway to two-thirds full, allowing room for the cake to rise.
- Cover the slow cooker with its lid and cook on HIGH for approximately 2–3 hours or on LOW for 3–4 hours.Cooking time varies by appliance, cake thickness, and temperature. Begin checking toward the earlier end of the range. Avoid lifting the lid frequently because this releases heat and extends cooking time.
- Insert a toothpick into the center of the cake. It should come out clean or with a few moist crumbs, but no wet batter. If the center is still undercooked, cover the slow cooker and continue cooking in 15–20-minute intervals.The top may remain lighter in color than an oven-baked cake because slow cookers do not brown the surface as effectively.
- If you want a richer finish, place the chocolate chips and heavy cream in a heat-safe bowl. Warm them gently in short microwave intervals, stirring between each interval, until the chocolate melts and the mixture becomes smooth.Let the ganache cool slightly until it reaches a pourable consistency.
- Turn off the slow cooker and remove the lid. Allow the cake to rest for 15–20 minutes before carefully removing or slicing it.Drizzle the chocolate ganache over the cake and garnish with chocolate shavings, berries, or a light dusting of cocoa powder. Serve warm or at room temperature.
Notes
- Measure accurately: Use the correct quantities of flour, cocoa powder, and leavening agents for a balanced cake texture.
- Use unsweetened cocoa powder: This provides a deep chocolate flavor without adding unnecessary sweetness.
- Avoid overmixing: Stir the batter only until the ingredients are combined to help keep the cake tender.
- Expect thin batter: Adding hot water or coffee creates a thinner batter that helps produce a moist chocolate cake.
- Choose the right slow cooker: A 5- to 6-quart appliance works well for this recipe, although cooking time varies by model.
- Keep the lid closed: Opening the lid repeatedly releases heat and can delay cooking.
- Check the center carefully: The middle may need more time than the outer edges, so test with a toothpick before serving.
- Cool before storing: Allow the cake to cool before transferring leftovers to a covered container.
