Creating your Double Chocolate Keto Mug Cake is incredibly simple. Follow these easy steps:

1. Combine Dry Ingredients: In a microwave-safe mug, mix the almond flour, cocoa powder, erythritol, baking powder, and salt until well combined.
2. Add Wet Ingredients: Crack the egg into the mug and add the almond milk, melted butter, and vanilla extract. Stir until the mixture is smooth and free of lumps.
3. Incorporate Chocolate Chips: If desired, fold in the sugar-free chocolate chips for an extra chocolatey experience.
4. Microwave: Place the mug in the microwave and cook on high for 60-90 seconds. Start with 60 seconds, then check for doneness. The cake should be set but still moist.
5. Cool Slightly: Allow the mug cake to cool for a minute or two before enjoying. This will help set the texture and enhance the flavor.
6. Optional Toppings: Top with whipped cream, a sprinkle of cocoa powder, or more chocolate chips, if desired.
