The Perfect Recipe for Microwave Sponge Cake

Are you craving a delicious homemade cake but don’t have the time or patience to bake it in the oven? Look no further! In this article, we will share with you a simple and quick recipe for a mouthwatering sponge cake that can be made in the microwave. With just a few ingredients and minimal effort, you can enjoy a fluffy and moist cake in no time. So, let’s get started!


Before we dive into the recipe, let’s gather all the necessary ingredients:

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup milk
  • 1/4 cup vegetable oil
  • 3 eggs
  • 1 teaspoon baking powder
  • 1 teaspoon vanilla extract
  • A pinch of salt


Now that we have everything we need, let’s proceed with the step-by-step instructions:

  1. Prepare the batter: In a large mixing bowl, combine the flour, sugar, baking powder, and salt. Mix well to ensure all the dry ingredients are evenly distributed.
  2. Add the wet ingredients: In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract until well combined.
  3. Combine the mixtures: Gradually pour the wet ingredients into the dry ingredients while stirring continuously. Mix until you have a smooth and lump-free batter.
  4. Microwave the cake: Pour the batter into a microwave-safe dish or a silicone cake mold. Make sure to leave some space at the top for the cake to rise. Place the dish in the microwave and cook on high power for 5 minutes.
  5. Check for doneness: After 5 minutes, insert a toothpick or a skewer into the center of the cake. If it comes out clean, the cake is ready. If not, microwave for an additional 1-2 minutes until fully cooked.
  6. Cool and serve: Once the cake is cooked, remove it from the microwave and let it cool for a few minutes. Gently remove the cake from the dish or mold and transfer it to a serving plate. You can enjoy it as is or add your favorite frosting or toppings.

Tips for Success

To ensure your microwave sponge cake turns out perfect every time, here are some helpful tips:

  • Use a microwave-safe dish or silicone cake mold to prevent any unwanted reactions or melting.
  • Make sure your microwave is clean and free from any food debris to avoid any unwanted flavors or odors.
  • Do not overmix the batter. Mix until the ingredients are just combined to avoid a dense cake.
  • Adjust the cooking time based on the wattage of your microwave. If your microwave has a higher wattage, you may need to reduce the cooking time slightly.
  • Allow the cake to cool before removing it from the dish or mold to prevent it from breaking apart.
