Ingredients

Cake Batter

  • 90g (3 oz) sugar-free dark chocolate (85% or keto chocolate chips)

  • 4 tablespoons unsalted butter

  • 2 large eggs

  • 2 tablespoons powdered erythritol or monk fruit sweetener

  • 2 tablespoons almond flour

  • 1 tablespoon unsweetened cocoa powder

  • ½ teaspoon vanilla extract

  • pinch of salt


Molten Chocolate Center

  • 30g sugar-free chocolate pieces


Optional Toppings

  • fresh raspberries

  • whipped cream

  • powdered erythritol (for dusting)

  • keto vanilla ice cream


Step-by-Step Instructions

Step 1 – Prepare the Ramekins

Preheat oven to 180°C (350°F).

Grease two small ramekins with butter.

Lightly dust the inside with cocoa powder to prevent sticking.


Step 2 – Melt Chocolate and Butter

In a heatproof bowl combine:

  • dark chocolate

  • butter

Melt using either:

• microwave in 20-second intervals
or
• double boiler method

Stir until the mixture becomes smooth and glossy.

Let it cool slightly.


Step 3 – Prepare the Egg Mixture

In another bowl whisk together:

  • eggs

  • powdered sweetener

  • vanilla extract

Whisk for about 1–2 minutes until slightly fluffy.


Step 4 – Combine Ingredients

Slowly pour the melted chocolate mixture into the egg mixture while whisking.

Then add:

  • almond flour

  • cocoa powder

  • pinch of salt

Mix until a smooth batter forms.


Step 5 – Fill the Ramekins

Pour half the batter into the ramekins.

Add a few pieces of chocolate in the center.

Then cover with the remaining batter.

This creates the lava center when baked.


Step 6 – Bake

Bake for 10–12 minutes.

Important:

• The edges should be firm
• The center should still be soft

Do not overbake or the lava center will disappear.


Step 7 – Serve

Let the cakes cool for 1 minute.

Run a knife around the edge and flip onto a plate.

Cut into the cake and enjoy the molten chocolate lava flowing out.

Top with:

• raspberries
• whipped cream
• powdered erythritol
