Proper Mixing Technique: Ensure thorough mixing of the cake batter to achieve a smooth and consistent texture. Pay attention to incorporating the softened butter evenly into the dry ingredients before adding the liquids. This prevents lumps in the batter and ensures a uniform rise during microwaving.
Microwaving Time: Microwave ovens vary in power, so adjust the cooking time accordingly. Start with the lower end of the suggested time range (60 seconds) and check the cake's doneness by inserting a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready. If not, continue microwaving in short intervals until fully cooked to avoid overcooking and drying out the cake.
Topping Application: For the perfect finishing touch, generously sprinkle the cinnamon sugar over the warm cake just after removing it from the microwave. The residual heat helps the cinnamon sugar adhere to the cake, creating a deliciously sweet and aromatic crust. If transferring the cake onto a plate, do so gently to preserve its shape, and then immediately sprinkle with cinnamon sugar for maximum flavor.
