First, gently melt the peanut butter and butter together in a microwave-safe bowl. Heat in short bursts (15-30 seconds), stirring after each, until smooth and well combined.
In a separate medium bowl, whisk together the almond flour, Swerve Sweetener, and baking powder until there are no clumps.
Now, stir in the eggs, vanilla extract, your melted peanut butter mixture, and water into the dry ingredients. Mix until everything is wonderfully combined and smooth.
Gently fold in the sugar-free dark chocolate chips.
Divide the batter evenly among 6 ramekins or mugs. Microwave each mug cake for about 1 minute. They’re ready when they look puffed up and set.
