Crockpot White Chocolate Raspberry Lava Cake Tips, FAQ & printable recipe

Tips for success

For the best texture, use a slow cooker that is 6 quarts or larger. If using a smaller slow cooker, the cake may be thicker and require a longer cooking time.

Always grease the insert well to ensure easy serving. Let the cake rest for 5 minutes after turning off the slow cooker to allow the sauce to settle slightly.

To achieve a more pronounced lava effect, add an extra 1/2 cup of white chocolate wafers and 1/4 cup of cream. If you prefer a less sweet dessert, reduce the jam to 3/4 cup. The almond extract is subtle but enhances the raspberry flavor; if you don't have it, use an additional 1/2 teaspoon of vanilla extract.

Variations

• Chocolate Raspberry Lava Cake: Swap the white cake mix for a chocolate cake mix and use semisweet chocolate chips instead of white chocolate. The raspberry jam and berries still provide a tart contrast to the rich chocolate.
• Strawberry White Chocolate: Replace raspberry jam with strawberry preserves and use fresh sliced strawberries instead of raspberries. The flavor is sweeter and more mellow, perfect for spring.
• Lemon Blueberry: Use a lemon cake mix, add 1 tablespoon of lemon zest to the batter, and substitute blueberry jam and fresh blueberries for the raspberry. Omit the almond extract and use vanilla only.
• Caramel Apple: Use a spice cake mix, add 1 teaspoon of cinnamon to the batter, and layer with apple pie filling and caramel sauce instead of raspberry. Top with white chocolate or butterscotch chips.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days. The sauce may thicken; stir in a splash of milk when reheating.

Freezer

Freeze the cooled cake in an airtight container for up to 2 months. Thaw overnight in the refrigerator and reheat in the microwave or oven.

Reheat

Reheat individual servings in the microwave for 30-60 seconds, or in a 350°F oven for 10-15 minutes until warmed through.

Store leftover cake in an airtight container in the refrigerator for up to 3 days. The sauce will thicken when chilled. Reheat individual portions in the microwave for 30-45 seconds or in a 350°F oven for 10 minutes until warm. Stir before serving to redistribute the sauce.

The batter can be prepared up to 1 day ahead and stored in the refrigerator in an airtight container. When ready to cook, pour the batter into the greased slow cooker and proceed with the recipe.

You may need to add 15-20 minutes to the cooking time if the batter is cold. The cooked cake can also be made a day ahead and reheated.

Serving ideas

Serve the lava cake warm, straight from the slow cooker. Scoop generous portions into bowls, making sure to include the molten sauce from the bottom.

A scoop of vanilla ice cream is the classic accompaniment, but whipped cream or a drizzle of raspberry sauce also work beautifully. Garnish with fresh raspberries for a pop of color and tartness.

This dessert is perfect for casual gatherings or holiday dinners. Set up a self-serve station with bowls, spoons, and toppings like crushed nuts or chocolate shavings.

The slow cooker keeps the cake warm for hours, so guests can help themselves. For a more elegant presentation, spoon the cake into individual ramekins and top with a mint leaf.

Crockpot White Chocolate Raspberry Lava Cake

Prep 15 minCook 2 h 15 minTotal 2 h 30 minServes 8

Ingredients

• 2 tbsp unsalted butter, melted (for greasing the Crockpot)
• 1 box white cake mix (15.25 oz)
• 3 large eggs
• 1/2 cup vegetable oil
• 1 cup water
• 1 tsp vanilla extract
• 1/2 tsp almond extract
• 1 cup seedless raspberry jam
• 2 cups fresh raspberries
• 1 1/2 cups white chocolate wafers or chips
• 1/2 cup heavy cream
• Vanilla ice cream, for serving
• Fresh raspberries, for garnish, to taste

Instructions

1. Grease the inside of a 6-quart slow cooker with the melted butter, covering the bottom and about 2 inches up the sides. In a large bowl, whisk the white cake mix, eggs, vegetable oil, water, vanilla extract, and almond extract until smooth and no lumps remain. The batter will be thin.
2. Pour the batter into the prepared slow cooker and spread it evenly. Drop spoonfuls of raspberry jam over the batter, then scatter the fresh raspberries on top. Use a knife or spatula to gently swirl the jam and berries into the batter, creating ribbons without fully mixing.
3. Sprinkle the white chocolate wafers evenly over the top of the batter. Pour the heavy cream over the white chocolate, covering as much of the surface as possible. Do not stir; the cream will help melt the chocolate into a sauce as the cake bakes.
4. Cover the slow cooker with the lid and cook on HIGH for 2 hours and 15 minutes, without opening the lid during cooking. The cake will rise and turn golden around the edges, while the center remains moist and saucy. The white chocolate and raspberry mixture will bubble around the edges.
5. After 2 hours and 15 minutes, carefully remove the lid. The cake should be golden around the edges and the center should be moist and tender, not raw. To check, insert a toothpick into the center; it should come out with moist crumbs, not wet batter. The internal temperature of the cake should reach 160°F (71°C) to ensure the eggs are fully cooked.
6. Turn off the slow cooker. Scoop the warm cake into bowls, making sure to include the molten white chocolate raspberry sauce from the bottom. Top with a scoop of vanilla ice cream and garnish with fresh raspberries. Serve immediately.
