Molten Biscoff Skillet Lava Cake

This Molten Biscoff Skillet Lava Cake is the ultimate cookie butter indulgence. A tender, spiced cake bakes around a hidden core of frozen Biscoff spread that turns into a warm, flowing lava when you cut into it.

Topped with cold vanilla ice cream and crunchy cookie crumbs, every spoonful is a contrast of textures and temperatures. It's a dramatic dessert that comes together in under 30 minutes, perfect for impressing guests or satisfying a serious sweet tooth.

Biscoff lovers, this is the dessert of your dreams. A rich, brown-sugar batter is baked in a cast iron skillet until the edges are set and the center is still soft, hiding a molten core of cookie butter.

The secret is freezing the spread before baking so it stays intact until the heat releases it as a warm, spiced lava. With a scoop of vanilla ice cream on top, it's a dessert that feels both nostalgic and exciting. Serve it straight from the skillet for maximum wow factor.

Ingredients

Why this recipe works

The method of freezing the Biscoff spread is the key to the molten center. As the cake bakes, the batter cooks and sets around the frozen dollop, which slowly melts into a thick, flowing lava.

This creates a distinct contrast between the tender cake and the gooey center, ensuring every bite has that dramatic, molten moment.

Baking in a cast iron skillet isn't just for looks. The heavy pan distributes heat evenly, helping the edges cook and puff while the center remains moist.

The high oven temperature and short baking time further ensure the outside is set while the inside stays soft, giving you that perfect lava effect without overbaking.

Notes and substitutions

Use a high-quality Biscoff spread for the best flavor. The batter uses the spread in two ways: melted into the mixture for a deep cookie butter taste, and frozen as a solid dollop for the lava center. If you can't find Biscoff, any speculoos-style cookie butter will work.

The eggs and egg yolks add richness and help the cake set just enough. Be sure to whisk them into the melted butter mixture until the mixture is pale and thick, which incorporates air and contributes to a lighter texture. The crushed cookies in the batter add a pleasant crunch and extra spice.

• Biscoff spread: Any cookie butter spread, such as speculoos or other brands.
• Unsalted butter: Salted butter works, but reduce added salt if any.
• Vanilla extract: Vanilla bean paste or the seeds from one vanilla bean.
