Slow Cooker Chocolate Lava Cake – Gooey Crockpot Dessert for 8

Slow Cooker Chocolate Lava Cake is the ultimate no-fuss dessert for busy nights when you want something rich, warm, and effortlessly gooey.

I remember the first time I tried this in my own crockpot. I wanted a dessert that felt special but didn’t eat up the evening after work. I tossed the batter together in 10 minutes, poured the hot water over the top, and let the slow cooker do the rest. When I lifted the lid, the kitchen smelled like a bakery and the sauce pooled under a tender chocolate cake. I served it with scoops of vanilla ice cream and watched everyone dig in. That easy win is exactly why I keep this recipe in my weeknight dessert rotation.

How to Make Slow Cooker Chocolate Lava Cake

This section walks you through the simple method so you can get perfect results every time. I’ll explain the tools, timing, and what to look for so you feel confident using your slow cooker.

What You’ll Need (Ingredients and Tools)

Below are the exact ingredients you need, plus a quick note on tools. This is a classic easy chocolate lava cake you can make with pantry staples. I list the measurements the same way the recipe card will, so nothing gets lost between the post and the recipe box.

• 1 cup all-purpose flour
• 3/4 cup granulated sugar
• 3 tablespoons cocoa powder (see note 1)
• 2 teaspoons baking powder
• 1/4 teaspoon salt
• 1/2 cup milk
• 1/3 cup butter melted
• 2 teaspoons vanilla extract
• 3/4 cup granulated sugar (for the topping)
• 3/4 cup brown sugar firmly packed
• 1/4 cup plus 2 tablespoons cocoa powder
• 2 1/4 cups hot water
• Vanilla ice cream or whipped cream, for serving
• Maraschino cherries, optional

Tools: 4- to 6-quart slow cooker (crockpot), mixing bowls, whisk, measuring cups, and a ladle or large spoon. Nonstick spray helps remove the cake easily.

Step-by-Step Slow Cooker Chocolate Lava Cake Instructions

Keep it simple and trust the slow cooker. Below I break the process into clear steps and include the cooking settings I use. I also give troubleshooting cues so you know when the cake is done.

1. Prep the slow cooker: Coat your slow cooker insert with nonstick spray so the cake lifts out easily. I usually give the insert a quick spray, then set it aside while I mix.
2. Mix the dry cake ingredients: In a large bowl, whisk together the flour, sugar, and cocoa powder along with the baking powder and salt. Make sure the cocoa is lump-free so the batter is smooth.
3. Mix the wet ingredients: In a separate bowl, whisk the milk, melted butter, and vanilla. The melted butter should be warm but not hot so it doesn’t cook the milk or eggs (there are no eggs here, but warm butter helps mix everything evenly).
4. Combine batter: Make a well in the dry ingredients, pour the wet ingredients into that well, and whisk until smooth. Scrape the bowl so you get all the flour mixed in. Then pour this batter into the bottom of the prepared slow cooker.
5. Prepare the topping: In a small bowl, whisk together the granulated sugar, brown sugar, and the extra cocoa powder. Evenly sprinkle this mixture over the top of the batter in the slow cooker. The sugars and cocoa will form the chocolate sauce as it cooks.
6. Add the hot water: Carefully pour the 2 1/4 cups of hot water evenly over the top. Don’t stir. The water will sink through and create that rich sauce under the cake while the batter rises above it.
7. Cook: Cover and cook on HIGH for 3 to 4 hours or LOW for 5 hours. I usually cook on HIGH for about 3 1/2 hours so the top is set and a toothpick comes out clean with a few crumbs attached. If you like a firmer cake, lean toward the 4-hour mark.
8. Check for doneness: Use a toothpick in the center. It should come out clean with a few moist crumbs stuck to it. The cake will be set on top but soft and tender. The sauce collects on the bottom and is ready to spoon over each serving.
9. Serve: Spoon slices into bowls or on plates, top with vanilla ice cream or whipped cream, and spoon the hot chocolate sauce from the slow cooker over the top. Add a maraschino cherry if you want a classic diner touch.

Jake’s Tips for Perfect Slow Cooker Chocolate Lava Cake

Here are the short, practical tips I use every time to make this dessert better and easier.

• Room temperature milk and warm melted butter mix together faster and give a smoother batter. I don’t overheat the butter—just warm enough to melt.
• Use hot water straight from the kettle. It helps dissolve the sugars and makes that deep, glossy sauce under the cake. No stirring.
• If your slow cooker runs hot, check at 3 hours. Not all slow cookers heat the same, and you want the top set but not dry.
• For easy cleanup, line the slow cooker insert with a circle of parchment before spraying. The cake lifts out faster and the insert cleans with one wipe.

Slow Cooker Chocolate Lava Cake FAQs

I get a few common questions about this recipe. I’ll answer them the way I would if you asked me in the kitchen.

• Can I make this ahead?
  

  Yes. You can bake it, let it cool, then cover and store at room temperature for 2 to 3 days. Reheat gently in the slow cooker on LOW with the lid slightly askew or microwave individual servings for 20-30 seconds so the sauce warms up but the cake doesn’t dry out.
• Can I use a different cocoa?
  

  Either natural or Dutch-process unsweetened cocoa powder works. Don’t use hot chocolate mix. The note in the recipe reminds you to use baking cocoa for the best flavor.

• Is this the best slow cooker dessert for a crowd?
  

  It’s one of my favorites because it’s simple to scale and tastes homemade and decadent. If you want more desserts like this, check other slow cooker desserts that pair well with ice cream.

• Can I convert this to a crockpot lava cake recipe for a smaller cooker?
  

  Yes. Reduce the quantities proportionally and use a small insert. Cooking time will likely be shorter, so start checking at about 2 hours for a small 2- to 3-quart cooker.
• What about serving suggestions?
  

  Top it with vanilla ice cream, fresh berries, or a sprinkle of flaky sea salt. A spoonful of whipped cream also makes for a classic pairing for chocolate lava cake with ice cream.
