Pre-heat oven to 350⁰ degrees F, fan forced.
Using a stand mixer or handheld electric mixer, beat the eggs and vanilla until thick and creamy.
Place the chocolate, butter and coffee in a microwave-safe bowl and heat in bursts until melted and smooth.
Add the chocolate mixture to the eggs, beating on low until combined.
Fold the dry ingredients (almond flour and sweetener) through until well incorporated.
Grease two single-serve 1 cup ramekins very well. Pour the batter into the two greased ramekins and bake for 10-15 minutes until the top has set but still jiggles. (Baking time will depend on the size and shape of your ramekin)
Sit aside for five minutes before upturning in a serving plate.
These Lava Cakes will need to be eaten straight away and do not store well. You can refrigerate but you will loose that gooey chocolate center.
