Rich, gooey slow cooker chocolate lava cake with a molten center — easy, decadent, and perfect for chocolate lovers.

Prep Time 15 minutes

Cook Time 2 hours

Additional Time 10 minutes

Total Time 2 hours 25 minutes

Ingredients

• ¾ cup (1½ sticks) unsalted butter, melted
• 1 cup semi-sweet chocolate chips
• ¾ cup unsweetened cocoa powder
• 1 cup all-purpose flour
• ¾ cup granulated sugar
• ½ cup brown sugar, packed
• ½ teaspoon salt
• 4 large eggs, room temperature
• 2 teaspoons vanilla extract
• ¾ cup hot water
• Optional: ½ cup extra chocolate chips for extra molten pockets

Instructions

1. Prepare your slow cooker — Generously spray a 6-quart or larger slow cooker insert with non-stick cooking spray, or line it with parchment paper (with overhang for easy removal). This is your insurance against sticking!
2. Melt the chocolate & butter — In a large microwave-safe bowl, combine the butter and 1 cup semi-sweet chocolate chips. Microwave in 30-second bursts, stirring well after each, until completely smooth and glossy.
3. Bloom the cocoa — Sift the cocoa powder directly into the melted chocolate mixture. Pour the hot water over the cocoa and whisk vigorously until silky-smooth and shiny. This step unlocks maximum chocolate flavor!
4. Add the sugars & vanilla — Stir in both granulated sugar, brown sugar, salt, and vanilla extract. Mix until everything looks uniform and glossy.
5. Mix in the eggs — Add the eggs one at a time, whisking well after each addition. The batter should become thick, shiny, and slightly lighter in color.
6. Fold in the flour — Gently fold in the flour with a spatula or whisk just until no dry streaks remain. Do not overmix — a few small lumps are fine. Overmixing can make the cake tough.
7. Optional extra chocolate — If you want an even more dramatic lava experience, scatter the extra ½ cup chocolate chips evenly over the surface of the batter now.
8. Transfer to slow cooker — Pour the batter into your prepared slow cooker. Smooth the top lightly with a spatula so it cooks evenly.
9. Cook low & slow — Place a double layer of paper towels under the lid to catch condensation. Cover and cook on LOW for 2 to 2½ hours. Check at 2 hours — edges should be set, center should still look soft and slightly jiggly (that’s the lava!).
10. Rest, serve & enjoy — Turn off the slow cooker and let the cake rest for 10 minutes. Then scoop warm portions into bowls (it won’t slice cleanly — that’s part of the charm!). Serve with vanilla ice cream, whipped cream, fresh berries, or a dusting of powdered sugar. Pure chocolate heaven!

Notes

• Cooking time varies depending on your slow cooker model — newer ones tend to run hotter.
• The cake is best served warm when the center is at its gooiest.
• If the top looks too wet after cooking, leave the lid off for 10 minutes on warm setting to set the surface.
• This dessert is very rich — small portions go a long way!

Recipe Tips and Tricks

• Use a 6-quart or larger oval slow cooker for the best texture and even cooking.
• Line the slow cooker insert with parchment paper or grease very generously — this cake is sticky and can be difficult to remove otherwise.
• Resist lifting the lid during cooking — every peek adds 15–20 minutes to the cooking time.
• Check doneness around the 2-hour mark: the edges should be set, center should still look very soft and slightly jiggly.
• For a stronger lava effect, serve within 20–30 minutes after turning off the slow cooker.
• Place a double layer of paper towels under the lid to absorb excess moisture and prevent a soggy top.
• Use good-quality cocoa powder — it makes a noticeable difference in depth of flavor.
• Let the cake rest 10 minutes before scooping to allow the structure to set slightly for cleaner servings.

Ingredients Notes

• Unsalted butter — Provides richness and moisture. Unsalted lets you control the salt level. Melted butter incorporates more easily into the batter.
• Semi-sweet chocolate chips — These melt into the batter and create pockets of molten chocolate. Use good-quality chips (45–60% cocoa) for the best flavor and gooey texture.
• Unsweetened cocoa powder — Gives deep chocolate flavor without extra sweetness. Dutch-processed cocoa creates a darker, smoother taste, while natural cocoa gives a brighter chocolate note.
• All-purpose flour — Provides just enough structure so the cake holds its shape while staying soft. Too much flour = dry cake.
• Granulated sugar & brown sugar — The combination adds sweetness and moisture. Brown sugar contributes a subtle caramel note that pairs beautifully with chocolate.
• Eggs — Bind the batter and help create that signature fudgy-lava texture. Room temperature eggs mix more evenly.
• Vanilla extract — Enhances all the chocolate flavors — don’t skip it.
• Salt — A small amount balances sweetness and intensifies chocolate flavor.
• Hot water — Blooming the cocoa in hot water unlocks deeper flavor and creates a smoother batter.

Variations and Substitutions

• Dark Chocolate Lava Cake — Swap semi-sweet chips for 60–70% dark chocolate chips for a more intense, bittersweet experience.
• Peanut Butter Chocolate Lava — Drop 4–6 tablespoons of peanut butter in spoonfuls over the batter before cooking — it creates delicious molten peanut butter pockets.
• Mocha Lava Cake — Add 2–3 tsp instant espresso powder to the hot water for a rich coffee-chocolate flavor.
• Raspberry Chocolate — Scatter fresh or frozen raspberries over the batter before cooking for bright, tangy bursts.
• Gluten-Free Version — Replace all-purpose flour with a 1:1 gluten-free flour blend (with xanthan gum). Texture remains very close to the original.
• Dairy-Free — Use plant-based butter, dairy-free chocolate chips, and almond or oat milk instead of regular milk.
• Double Chocolate — Stir in ½ cup extra chocolate chips or chopped chocolate pieces for even more gooey pockets.
• Spiced Mexican Chocolate — Add 1 tsp cinnamon and a pinch of cayenne pepper for a warm, spicy twist.
• Brownie-Like Texture — Reduce hot water by 2 tbsp and increase flour by 2 tbsp for a denser, more brownie-style result.

Storage Options

• Room temperature — Best enjoyed fresh the same day. Store leftovers covered for up to 1 day.
• Refrigerator — Keep in an airtight container for 3–4 days. Reheat individual portions gently in the microwave (20–30 seconds) to revive the gooey center.
• Freezer — Freeze tightly wrapped portions for up to 2 months. Thaw overnight in the refrigerator and reheat slowly. Note: the molten center will be less dramatic after freezing.
