Can I bake a cake in my microwave?

Baking a cake in the microwave may seem like an unusual idea, but it is possible if done correctly. Microwaves can be used to make mug cakes, small individual cakes, and even full-size cakes. With some adaptations to ingredients and cooking times, cakes baked in the microwave can turn out moist and delicious.

What You Need to Know About Microwave Cakes

When baking a cake in the microwave, there are some key things to keep in mind:

  • Use microwave-safe cookware – Glass, ceramic, or high heat-resistant plastic containers work best.
  • Adjust cooking times – Microwaves cook much faster than conventional ovens, so recipes need shorter cooking times.
  • Use less sugar – Sugar absorbs microwave energy, so cut back on the amount of sugar in recipes.
  • Use oil instead of butter – Solid fats don’t melt well in the microwave, so substitute vegetable or canola oil for butter.
  • Stir partway through – Stop and stir batters halfway through cooking to prevent uneven cooking.
  • Allow standing time – Microwave cakes will be very hot initially, so allow time to cool and set after cooking.

With the right techniques, tools, and adapted recipe, moist microwave mug cakes, individual cakes, and even layer cakes can be made successfully.

Microwave Mug Cakes

Mug cakes are ideal for the microwave as they are made with just a few ingredients cooked in a mug for 1-2 minutes. Basic mug cake ingredients include:

  • All-purpose flour
  • Sugar
  • Oil
  • Eggs
  • Milk
  • Cocoa powder or chocolate chips (for chocolate cakes)
  • Leavening like baking powder or soda
  • Vanilla or other extracts

To make a basic microwave mug cake:

  1. Spray a large microwave-safe mug with nonstick spray.
  2. Add 2-3 tablespoons flour, 2 tablespoons sugar, 2 tablespoons oil, 1 egg, 2 tablespoons milk, and a dash of vanilla to the mug.
  3. Mix until just combined, trying not to overmix.
  4. Cook in the microwave on high for 1 minute. Check cake and cook for 10-30 more seconds if needed until set.
  5. Let cool for 1-2 minutes before eating.

The batter can also be customized with additions like cocoa powder, chocolate chips, peanut butter, or fruit. Reduce cooking time to 45 seconds for chunkier batters.

Tips for Microwave Mug Cakes

  • Use fresh eggs – Old eggs won’t rise properly.
  • Don’t overmix – Overbeating adds too much air to the batter.
  • Spray the mug – Grease it well so the cake releases after cooking.
  • Don’t overbake – Start checking after 45 seconds to prevent drying out.
  • Allow standing time – Let rest 1-2 minutes before eating so it sets up.

With the right timing and a well-greased mug, mug cakes can come out perfectly moist after just a minute or so in the microwave.

Microwave Individual Cakes

In addition to mug cakes, small individual sized cakes can be made in the microwave using ramekins or custard cups. These work well for making individual desserts like molten lava cakes. To make microwave individual cakes:

  1. Grease 1-2 ramekins or custard cups with butter or nonstick spray.
  2. Fill cups about 2/3 full with cake batter, like vanilla, chocolate, or spice cake batter.
  3. Microwave each ramekin on high for 1 1/2 to 2 1/2 minutes, until a toothpick inserted comes out clean.
  4. Cool for 2 minutes before inverting onto a plate.

Microwaved individual cakes will be fully cooked through but may be slightly domed on top. Use recipes designed for microwave cakes rather than oven-baked cakes. Reducing sugar, using oil instead of butter, and liquid ingredients like sour cream help cakes bake up moist.

Tips for Microwaved Individual Cakes

  • Grease ramekins well – Coat thoroughly with butter or nonstick spray.
  • Don’t overfill – Fill cups only 2/3 full to allow rising room.
  • Rotate cups – If microwaving two ramekins, swap their positions halfway through cooking.
  • Test for doneness – Use a toothpick to check if cake is fully cooked through.
  • Cool before removing – Let cakes cool a few minutes before unmolding to avoid crumbling.

With the right recipes and techniques, microwave individual cakes can be just as moist, tender and delicious as their oven-baked counterparts.

Full-size Microwave Layer Cakes

While it may seem surprising, it is actually possible to bake an entire layer cake in a microwave oven. This takes a little more finessing but can be done with adapted recipes and the right cookware.

To bake a full size microwave cake:

  1. Use microwave-safe bakeware like a glass cake dish or silicone mold.
  2. Make a cake batter recipe designed for microwave baking, reducing sugar.
  3. Pour into prepared pan and smooth the top.
  4. Microwave on high for 4-6 minutes, checking frequently.
  5. When done, a toothpick inserted should come out clean.
  6. Let cool completely before frosting and assembling.

Special microwave cake recipes using ingredients like sour cream, oil and extra eggs rather than butter produce moist, tender cakes. Reducing mixing time and stirring the batter halfway through prevents tunneling.

Tips for Full-Size Microwave Cakes

  • Use the right pan – Glass and silicone pans conduct heat evenly.
  • Adapt ingredients – Substitute oil for butter and use extra eggs for rise.
  • Don’t overmix – Gently mix just until combined to avoid toughness.
  • Stir midway – Pausing to stir helps prevent tunneling and hotspots.
  • Test doneness – Check frequently and miccook just until a toothpick comes out clean.
  • Cool completely – Allow at least 1-2 hours before frosting for easier handling.

With moist adapted recipes and the right microwave techniques, full layered cakes can be baked successfully.

  • Use microwave-safe cookware made of materials that heat evenly like glass or silicone.
  • Grease cookware well with butter, oil or nonstick spray so cakes release easily.
  • Adjust recipes by using less sugar, oil instead of butter, and extra eggs or liquids.
  • Mix batters very gently to avoid overmixing and dense cakes.
  • Microwave in short intervals to avoid overcooking, testing frequently with a toothpick.
  • Stop and stir or rotate items midway through cooking for even heating.
  • Always allow microwave cakes to cool before handling to finish setting up.
  • Start with mug cakes or individual cakes before attempting full layer cakes.

With the right adapted recipes, tools and techniques, microwave cakes can come out just as moist and delicious as traditionally baked cakes.

Frequently Asked Questions

Can any cake recipe be made in the microwave?

No, traditional cake recipes designed for oven baking likely won’t work well microwaved without adjustments. Microwave cake recipes are adapted using less sugar, extra liquids, and ingredients like oil instead of butter. Some oven-baked recipes may work if sugars are reduced and cooking times decreased.

How long does it take to microwave a cake?

Cooking times depend on the size of the cake. A mug cake takes 1 minute or less, individual cakes take 1 1⁄2 – 3 minutes, while a full 9-inch round cake takes 4-6 minutes to microwave. Always cook cakes in short intervals and check frequently for doneness.

Why do microwave cakes sink in the middle?

Overmixing, overcooking, or using too much sugar can all cause dense microwave cakes that sink in the center. Use less sugar, mix gently, and cook just until done to get cakes that rise properly without sinking.

Can I use a metal pan to microwave a cake?

No, only microwave-safe pans like glass, ceramic, high-heat plastic, or silicone should be used. Metal pans can damage the microwave or cause sparks. For best results, use containers made specifically for microwave baking.

Do microwave cakes taste the same as oven cakes?

Adapted microwave cake recipes can taste just as moist and delicious as oven versions. Because they cook faster at higher heat, flavorings may taste slightly different. Cool completely before frosting for the best flavor.


With the right tools, ingredients, recipes and techniques, delicious cakes can absolutely be baked in the microwave. Mini mug cakes cook up in under a minute, while individual sized cakes or layers take just a few minutes. Adapting traditional recipes is key for microwave success. Greasing pans well, cutting back on sugar, and not overmixing or overcooking results in tender, moist microwave cakes. Give microwave baking a try for speedy cake satisfaction any time.
