Slow-Cooker Biscoff Cookie Butter Lava Cake Tips, FAQ & printable recipe

Tips for success

For an enhanced flavor profile, consider adding a pinch of sea salt to the cake batter to balance the sweetness of the Biscoff.

If you prefer a more pronounced spiced flavor, you can add an additional half-teaspoon of ground cinnamon or a quarter-teaspoon of ground ginger to the dry cake mix before combining it with the cookies.

When serving, ensure the vanilla bean ice cream is slightly softened so it melts into the warm cake. The temperature contrast between the hot, gooey lava cake and the cold, creamy ice cream is the signature of this dessert.

Garnish each bowl generously with the remaining crushed cookies for an added textural crunch that complements the soft cake.

Variations

• Chocolate Biscoff Twist: Substitute the spice cake mix with a chocolate fudge cake mix. The combination of cocoa and caramelized cookie butter creates a deep, intense flavor profile that pairs exceptionally well with a scoop of vanilla ice cream.
• Nutty Biscoff Crunch: Fold in a half-cup of chopped toasted pecans or walnuts into the cake batter. The added crunch provides a sophisticated texture that complements the smooth, molten cookie butter filling and the tender spiced cake.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Freezer

The cake can be frozen for up to 1 month in a sealed container; thaw overnight in the refrigerator before reheating.

Reheat

Reheat individual portions in the microwave for 30 to 45 seconds until warm and the center is gooey again.

Transfer any leftover cake to an airtight container once it has cooled completely. Keep the container in the refrigerator to maintain the best quality. The cake can be kept for up to three days, though it is best enjoyed within the first twenty-four hours to ensure the texture remains moist and the flavors stay vibrant.

The dry cake mix and crushed cookies can be combined in an airtight container ahead of time. However, the wet ingredients and the layering process should be done immediately before cooking. This ensures the cake does not become dense or gummy, which can happen if the batter sits for too long before being exposed to heat.

Serving ideas

Serve the cake immediately while it is warm, scooping large portions into individual bowls. Ensure each serving includes a generous amount of the molten Biscoff center.

The addition of vanilla bean ice cream is essential for providing a creamy, cool balance to the intense, caramelized notes of the spiced cookie butter and cake base.

For a refined presentation, garnish each bowl with a whole Biscoff cookie placed vertically in the center.

An extra drizzle of melted cookie butter over the ice cream adds a professional touch, creating a beautiful contrast of colors and textures that makes this simple slow-cooker dessert feel like a decadent restaurant-quality treat.

Slow-Cooker Biscoff Cookie Butter Lava Cake

Prep 10 minCook 2 h 15 minRest 10 minTotal 2 h 35 minServes 8

Ingredients

• 1 box spice cake mix
• 1 cup crushed Biscoff cookies
• 1 cup creamy Lotus Biscoff cookie butter
• 1 cup warm spiced milk
• vanilla bean ice cream, for serving
• 1/4 cup melted Biscoff cookie butter, for serving
• 8 whole Lotus Biscoff cookies, for serving

Instructions

1. Combine the spice cake mix with the crushed Biscoff cookies in a large mixing bowl. Stir until the cookies are evenly distributed throughout the dry cake mix base. Prepare the slow cooker by lightly greasing the interior to ensure the cake releases easily after the long cooking time.
2. Spread the cake batter mixture into the bottom of the 6-quart slow cooker. Carefully dollop the creamy cookie butter into the center of the batter. Pour the warm spiced milk over the top of the mixture. Gently swirl the cookie butter slightly into the batter to create a marbled effect, but avoid over-mixing.
3. Cover the slow cooker with the lid. Cook on the HIGH setting for 2 hours and 15 minutes. The cake is finished when the edges are set and bubbling with the caramelized cookie butter lava. Turn off the heat and allow the cake to rest for 10 minutes before scooping into bowls. Serve warm topped with a scoop of vanilla ice cream, a drizzle of melted cookie butter, and a whole Biscoff cookie.
