One-Bowl Low-Carb Chocolate Lava Cake

A rich molten chocolate cake ready in minutes. This single-bowl treat delivers a gooey center with no added sugar, perfect for a quick low-carb dessert.

  • Total Time7 minutes
  • Yield3 1x

Ingredients

Scale
  • ½ cup 60 g Dutch-processed cocoa powder
  • ½ cup 96 g powdered monk fruit-erythritol blend
  • ¼ tsp fine sea salt
  • 3 tbsp 42 g unsalted butter, melted and cooled slightly
  • 3 large eggs (at room temperature)
  • 3 tbsp 45 ml heavy whipping cream
  • 1 tsp vanilla extract
  • About 3 oz (85 g high-quality sugar-free dark chocolate, roughly chopped)
  • Butter or nonstick spray (for greasing)

Instructions

  1. Grease the ramekins or mugs. In a microwave-safe bowl, melt the butter 30 to 40 seconds on high, then let it cool 1 minute.
  2. Whisk in the cocoa powder, powdered sweetener, and salt until a thick glossy paste forms.
  3. Add the eggs one at a time, whisking well after each. Whisk in the cream and vanilla until smooth and slightly aerated.
  4. Divide the batter evenly among the three ramekins, filling each half to two thirds full.
  5. Press one third of the chopped chocolate into the center of each portion, just below the surface.
  6. Microwave one at a time on full power 60 to 100 seconds in a 1000 W microwave, starting at 60 seconds. The cake should pull from the sides and the center should look soft and slightly glossy. If needed, continue in 10 to 15 second bursts.
  7. Rest 1 minute. Serve immediately. Optionally invert onto a small plate.

Notes

  • For deeper flavor, add ½ tsp instant espresso powder with the cocoa.
  • Choose sugar-free chocolate without maltitol when possible.
  • Ideal doneness: edges set, center jiggly not liquid.
  • Food safety: for a molten center use pasteurized eggs. If using regular eggs, cook until the center reaches 71°C which will reduce fluidity.
  • Best enjoyed fresh. Refrigerate leftovers up to 2 days. Reheat 20 to 30 seconds.
  • Serve with unsweetened whipped cream, a few berries, or a light dusting of powdered sweetener.
