Notes

– For the most intense lemon flavor, use freshly grated zest from organic lemons. – When microwaving, do not overcook; the cake should still be slightly moist in the center when removed, as it will continue to set as it cools. – To store, cover cooled mug cakes tightly and refrigerate for up to 2 days. Reheat gently in the microwave for 15-30 seconds. – I found that if my batter was too thick, adding an extra tablespoon of yogurt or a splash of almond milk helped achieve the perfect consistency for a tender cake.
