This optimized blueprint for a cookie dough mug cake requires exactly three minutes of preparation and sixty seconds of cooking time, yielding a dessert that rivals anything coming out of a traditional oven by relying on precise chemistry instead of eggs.
The goal is to heat the flour/fat matrix just past gelatinization without evaporating the residual moisture. When you pull the mug out, the center should still look slightly damp—this is calculated to resolve during the sixty-second cooling phase. The cooling step is non-negotiable; it allows the starches to set and the chocolate chips to reach a perfect, molten consistency. If using a 700W microwave, start with 90 seconds on 70% power and rest for 90 seconds. For an extra decadent experience, press a single square of chocolate into the very center of the dough before cooking for a lava-cake effect.
