What is Lava Cake?
A lava cake is a chocolate dessert known for its soft, tender cake exterior and warm, gooey chocolate center. Traditionally baked in small ramekins, the middle stays molten while the edges form a light cake layer. It is indulgent, rich, and perfect for chocolate lovers.
This slow cooker version works a little differently. Instead of ramekins, the cake cooks in a crockpot and is topped with a luscious chocolate sauce. When you scoop it out, you get a warm, fluffy cake with minimal effort and no need to watch the oven.
Tim's Tip: Don't lift the lid while it cooking so that the heat doesnt escape and it cooks evenly.

Tim's Top Expert Tips
- Don't overcook - some slow cookers cook hotter than others, so check your cake at the 2-hour mark. Overcooking can dry out the cake.
- Let it rest for 10 minutes before serving so the sauce thickens slightly.
- Serve warm for the best lava-like texture.
- If your sauce gets too thick, add a splash of milk to keep it silky and lava-like.

Helpful Tools and Equipment
- Slow Cooker - The key to this recipe! A standard 6-quart slow cooker works perfectly.
- Measuring Cups - Accurate measuring is important.
- Whisk - To blend the batter smoothly and prevent lumps.
- Glass Mixing Bowl - This 3 set will give you plenty of room to combine the cake batter without making a mess.
Storage
If you have leftovers, store the cake covered and the sauce separately for the best texture.
Allow the cake to cool completely, then place it in an airtight container and refrigerate for up to 3 days. Store the chocolate sauce in a separate airtight container in the refrigerator as well.
Reheat individual portions of cake in the microwave for 20-30 seconds or until warm. Warm the chocolate sauce in the microwave for 15-second intervals, stirring between each until smooth and pourable. Then simply pour the warm sauce over the cake before serving.
FAQs
No. Let the slow cooker work its magic without opening the lid.
This dessert is best served fresh and warm. Leftovers can reheat well if needed.
The cake is done when the edges are set, but the center seems jiggly.
