Start by lightly greasing two small microwave-safe bowls or mugs with cooking spray or a touch of coconut oil. This helps your cake pop right out!
In a separate small bowl, whisk together the melted butter, creamy almond butter, egg yolk, and fragrant vanilla extract until everything is smoothly combined.
Next, gently fold in the unsweetened cocoa powder, almond flour, Swerve Confectioners, stevia drops, and heavy cream. Mix until the ingredients are just combined into a delicious batter – try not to overmix!
Divide this chocolatey batter evenly between your two prepared mugs. Sprinkle the low-carb chocolate chips generously on top.
Pop each mug into the microwave and cook for about 1 to 1.5 minutes. You're looking for the edges to be set, but the center to still be wonderfully soft and fudgy, like a molten lava cake. Enjoy warm for the best experience!
