A fast and easy 5-minute mug cake featuring tart rhubarb balanced with sweet batter, perfect for a quick dessert or solo treat.
Do not overcook to avoid dryness; start checking at 90 seconds and add 10-second increments if needed. Use room temperature milk and oil for best results. Toss rhubarb with sugar before mixing to soften and reduce tartness. Let the cake rest briefly after microwaving to finish cooking and settle flavors.
