Before you start

Before you begin, ensure all ingredients are measured and ready. Bring the eggs to room temperature to ensure they incorporate smoothly into the batter. Preheat your oven to exactly 400°F (204°C) at least 20 minutes prior to baking.

Prepare your ramekins by greasing them thoroughly with butter or cooking spray, then dust them with finely crushed cookie crumbs, tapping out any excess to ensure an even coating. Having your workspace organized will make the whisking and assembly process seamless.

Ingredients at a glance (9)
  • 1 cup Biscoff cookie butter
  • 4 tbsp unsalted butter
  • 2 large eggs
  • 2 large egg yolks
  • 1/4 cup brown sugar
  • 1/2 tsp ground cinnamon
  • 1/4 cup all-purpose flour
  • crushed Biscoff cookies for serving
  • vanilla gelato for serving

Instructions

Preparation and Melting

  1. Prepare and Melt
    Preheat the oven to 400°F (204°C). Grease four ramekins and line the bottom and sides with crushed Biscoff cookie crumbs. In a saucepan or microwave-safe bowl, melt the cookie butter with the butter until smooth and combined.
    Look for The mixture should be glossy, smooth, and fully melted without burning.
    Tip Ensure the butter and cookie butter are completely incorporated to create a uniform base for the cake.

The ramekins are evenly coated with crumbs and the cookie butter mixture is completely melted, smooth, and glossy. Ensure there are no lumps in the butter mixture before proceeding to the egg whisking stage, as this ensures a uniform batter texture.

Mixing the Batter

  1. Whisk and Incorporate
    In a mixing bowl, whisk together the eggs, egg yolks, brown sugar, and ground cinnamon until light and frothy. Slowly whisk the melted cookie butter mixture into the egg mixture. Gently fold in the flour until just combined, being careful not to overmix the batter.
    Look for The batter should be thick, uniform in color, and smooth with no streaks of flour.
    Safe temperature 160°F (71°C) internal temperature (egg dishes)
    Tip Use room temperature eggs for better emulsification into the melted butter mixture.

The batter is thick, smooth, and well-combined. The flour is fully incorporated without any visible white streaks. The mixture should be airy from the whisking process, indicating that the cakes will have the correct light structure once baked.

Baking and Serving

  1. Bake and Serve
    Divide the batter evenly among the prepared ramekins. Place the ramekins on a baking sheet and bake for 11 minutes. The edges should be set while the center remains molten. Let rest for 5 minutes before serving topped with vanilla gelato and extra cookie crumbs.
    Look for The edges are firm and cake-like while the center jiggles slightly when the ramekin is nudged.
    Tip Do not overbake, or the center will lose its characteristic molten lava texture.

The cakes have risen slightly and the edges are firm to the touch. The center remains soft and molten. The cakes are ready to be rested briefly before being garnished and served warm with a scoop of vanilla gelato.

Common mistakes

A common mistake is overbaking, which causes the molten center to solidify. Keep a close eye on the oven timer, as even one extra minute can change the texture significantly.

Another error is not whisking the eggs and sugar enough; this mixture needs to be pale and frothy to provide the necessary structure.

Finally, failing to grease and coat the ramekins properly can cause the delicate cake to stick, making it difficult to unmold or serve elegantly.

How to tell it’s done

To determine doneness, observe the edges of the cakes; they should appear set, firm, and slightly pulled away from the sides of the ramekins. The center should still look soft and move slightly when the ramekin is gently shaken.

The cakes will continue to cook slightly from residual heat during the 5-minute resting period. The internal temperature of the cooked parts should reach 160°F (71°C) to ensure the eggs are safely cooked through while maintaining the signature molten center.
