Ingredients
- 4 oz Sugar-Free Dark Chocolate, chopped
- 1/4 cup Unsalted Butter
- 2 large Eggs
- 2 large Egg Yolks
- 3 tbsp Powdered Erythritol
- 1 tbsp Cocoa Powder
- 1/2 tsp Vanilla Extract
- Pinch of Sea Salt
How to Make
Step 1
Preheat oven to 425°F. Grease four 6-oz ramekins generously with butter and dust lightly with cocoa powder, tapping out the excess.
Step 2
Place the sugar-free dark chocolate and butter in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely smooth and melted. Let cool for 2 minutes.
Step 3
In a separate bowl, whisk together the eggs, egg yolks, powdered erythritol, and vanilla extract until pale and slightly thickened, about 2 minutes of vigorous whisking.
Step 4
Pour the melted chocolate mixture into the egg mixture and fold gently until just combined. Sift in the cocoa powder and sea salt, then fold again until smooth. Do not overmix.
Step 5
Divide the batter evenly among the prepared ramekins. Place them on a baking sheet and bake for exactly 12 to 13 minutes, until the edges are firm but the center still jiggles slightly when gently shaken.
Step 6
Let the cakes rest for 1 minute, then run a thin spatula around the edges. Invert each ramekin onto a plate, wait 10 seconds, and carefully lift the ramekin off. Serve immediately while the centers are still molten.
Helpful Tips
Grease the Ramekins Well
This is probably the most important prep step. If the ramekins are not greased properly, the cake will stick and won’t release cleanly when you flip it over.
Use softened butter and coat every inch of the inside, including the rim. Then dust with cocoa powder instead of flour to keep it low carb, and tap out anything that doesn’t stick to the sides.
Use Powdered Erythritol, Not Granular
Granular erythritol won’t dissolve properly into the batter, and you’ll end up with a gritty texture in the finished cake. Powdered erythritol blends in smoothly, which is exactly what you want here.
If you only have granular on hand, just blend it in a food processor or blender for about 30 seconds until it turns into a fine powder. It works just as well.
Don’t Skip Cooling the Chocolate
After you melt the chocolate and butter together, let it sit for 2 minutes before adding it to the eggs. If the chocolate is too hot when it hits the eggs, it will start to cook them and you’ll get scrambled bits in your batter.
You just need it to cool slightly, not go cold. Two minutes is enough. The bowl should still feel warm but not hot when you touch the outside of it.
Frequently Asked Questions
Can I make these lava cakes ahead of time?
Yes, you can fill the ramekins with batter and refrigerate them for up to 24 hours before baking. Just cover each one with plastic wrap and pop them in the fridge until you’re ready.
When you’re ready to bake, take them out of the fridge about 15 minutes early so they come closer to room temperature. You may need to add 1 extra minute to the bake time since the batter will still be a little cold.
