How to Bake a Cake in a Microwave: A Step-by-Step Guide

If you’re craving cake but don’t have access to a traditional oven, fear not! Baking a cake in a microwave is a quick and easy alternative that can satisfy your sweet tooth in no time. In this article, we’ll guide you through baking a cake in a microwave, step by step.


Before we begin, let’s gather the necessary ingredients:

  • 1 cup all-purpose flour
  • 1/2 teaspoon vanilla extract
  • 1/2 cup granulated sugar
  • 1/4 cup vegetable oil
  • 1/2 cup milk
  • 1 teaspoon baking powder
  • Pinch of salt
  • 1 egg


To bake a cake in a microwave, you’ll need the following equipment:

  • Microwave-safe bowl or dish
  • Microwave oven
  • Measuring cups and spoons
  • Whisk or fork
  • Oven mitts


Now that our ingredients and equipment are ready let’s start baking!

Step 1: Mix the dry ingredients

Whisk the flour, sugar, baking powder, and salt in a medium bowl until well combined.

Step 2: Add the wet ingredients

Whisk together the egg, milk, vegetable oil, and vanilla extract in another bowl until well combined.

Step 3: Combine the dry and wet ingredients

Pour the wet ingredients into the bowl with the dry ingredients and stir until combined. Be careful not to overmix, as this can make the cake challenging.

Step 4: Pour the batter into a microwave-safe dish

Grease a microwave-safe bowl or dish with cooking spray or butter. Pour the cake batter into the dish, leaving room at the top for the cake to rise.

Step 5: Microwave the cake

Place the dish in the microwave and cook on high for 5-6 minutes. Keep an eye on the cake as it cooks, as microwaves can vary in power. You’ll know the cake is made when the top is set and a toothpick inserted into the center comes clean.

Step 6: Let the cake cool

Using oven mitts, carefully remove the dish from the microwave and set it on a heat-safe surface. Let the cake cool for a few minutes before serving.

Tips for Success

Baking a cake in a microwave can be a bit tricky, but with these tips, you’ll be a pro in no time:

  • Use a microwave-safe dish that is the right size for your cake batter. If the dish is too small, the cake may overflow, and if it’s too large, it may not cook evenly.
  • Don’t overmix the batter. It can make the cake tough and rubbery.
  • Check the cake frequently as it cooks. Microwaves can vary in power, so it’s essential to keep an eye on the cake to ensure it doesn’t overcook or undercook.
  • Let the cake cool before serving. It will give it time to set and make it easier to slice and serve.


Baking a cake in a microwave is a quick and easy way to satisfy your sweet tooth. You can quickly whip up a delicious cake with just a few ingredients and essential equipment. Remember to follow the instructions carefully, and don’t be afraid to experiment with different flavors and toppings.
