- Prep: First, prep the base. Grease the crock pot and set it aside. In a large bowl (or directly in the crock pot), combine the chocolate cake mix, sour cream, vanilla, butter, eggs, and 1 ¼ cups milk. Mix well, then transfer the batter to the slow cooker.
- Layer: Next, layer on the pudding. In a separate bowl, whisk together the pudding mix and the remaining 2 cups of milk as directed. Gently pour the pudding mixture over the cake batter without stirring.
- Cook: Then, cook until molten. Secure the lid and cook on High for 2 hours or Low for 4 hours, until the edges are set and the center is glossy.
- Top: Finally, finish with toppings. Remove the lid and sprinkle mini marshmallows and chocolate chips over the top. Replace the lid and cook for 15 more minutes, just until the toppings melt and soften.
Prep Ahead Suggestions for Slow Cooker Lava Cake
- Mix the batter early: You can whisk together the cake batter (cake mix, sour cream, vanilla, butter, eggs, and 1 ¼ cups milk) up to 24 hours in advance. Store it covered in the fridge, then bring it to room temperature before adding it to the slow cooker.
- Prep the pudding mixture: The pudding thickens as it sits, so it’s best to whisk it right before cooking. If you must make it ahead, mix it up to 4 hours in advance, press plastic wrap directly onto the surface, and refrigerate.
- Measure toppings: Portion out the mini marshmallows and chocolate chips in a small airtight container. They’ll be ready to sprinkle the moment the cake finishes cooking.
- Grease the slow cooker insert: If you’re hosting or cooking later in the day, grease the insert in the morning and pop the lid back on. It saves a step when you’re ready to assemble.

- Oven Method (Classic Lava Cake Style): If you don’t want to use a slow cooker, the oven gives you a more traditional molten‑center texture. Bake at 350°F for 35–45 minutes, or until the edges are set and the center still looks glossy and slightly jiggly.
- Individual Ramekins (Restaurant‑Style): Perfect for date nights, dinner parties, or when you want a more elevated presentation.
- Air Fryer Method (Small‑Batch) Ideal for 2–4 servings or when you don’t want to heat the kitchen. Use small ramekins or a 6‑inch cake pan that fits your air fryer. Air fry at 325°F for 10–14 minutes, checking for set edges and a molten center. Add toppings and air fry for 1–2 minutes more until softened.
