Picture of microwave cake
This is absolutely, 100% the best microwave cake I have eaten in my life.* It takes 5 minutes to throw together and it tastes like sugar cookies and the texture is like REAL CAKE. I was watching Masterchef AU last night and Matt Preston was making a microwave sponge cake that involved passionfruit pulp for the liquid in the recipe. I was instantly excited. It looked great, and I needed it!

But there were problems: how much liquid is one passionfruit? what's the right amount of flour and baking powder if I'm not using self rising flour? how do I convert all the measurements so US readers will find it easy to make?

so I stayed up and experimented and then - PROBLEMS SOLVED

*Full disclosure: I am pretty much an expert in microwave sweets. I swear I've spent about a fourth of my adult life up late and making questionable food decisions.

P.S. Feeling like chocolate cake? Check out my chocolate microwave cake here!


Step 1: Ingredients:

Picture of ingredients:
  • 1/4 cup melted butter (50 g)
  • 1/4 cup sugar (50 g)
  • 1/2 cup flour (50 g)
  • 1/2 teaspoon baking powder
  • 1 egg
  • 2 tablespoons milk

The recipe above will serve two people - double for four cakes. That's what I was making today!

You will also need standard ramekins, cooking spray, plastic wrap and a microwave.

Just tried this
Really cool, thanks for uploading!
I can't upload pictures here so here's an imgur link
On average 40-50 seconds on a 1100 Watt microwave worked for me

can i make a big cake with this batter?
jessyratfink (author)  shamvil1 month ago

Perhaps! I've never tried. If you want to give it a go, I'd suggest doubling the recipe and cooking it in a 8 inch pan. 325 F for 20-30 could work. :)

Honestly, Is there such a thing as a "healthy" cake?

It is 3 in the morning and I needed a snack so I made this. Successfully. I put in about half an egg more in the mix and then whipped it with the teaspoon I had used to measure out the milk. Then put in 3 tablespoons in a cup and microwaved it for 1min. The result was the cake just like in the photo. I did not use any oil to coat / line the cup and as a result there was just a thin layer sticking to the cup. The taste however was not super great. It was spongy but it was just the slightest sweet. Do you add any flavors. Or is it just some base onto which some toppings like whipped cream or fruit need to be added - as you did?
Two more things.
1. A suggestion. Please refrain from using oil spray. They use aerosols for it and it is the same thing (same grade even) that is used in sprays from deodorants to shaving cream spray cans.
2. Thank You for this wonderful recipe. This would act as a base for me and now I shall experiment to get the flavor right for my palate.

Just like isochronous, I can't help but say something about this post. With regards to suggestion 1, why would you want to tell anyone how to act or what to say period. If someone wants to use aerosols, its no one's business but their own. I find busy body's like yourself intrusive and completely unnecessary. Keep it to yourself!!!

Sorry, but I just had to reply to this, because this is a "guilt by association" logical fallacy. Just because an aerosol is used in spray deodorant doesn't mean it's harmful. The four most common aerosol propellants in oil sprays are food-grade alcohol, nitrous oxide, carbon dioxide, and propane, none of which are harmful in any of oil spray's standard applications.

I regret that you did not state how much time to cook it in the microwave or at what power level. I wanted to make this but I couldn't without time and power level.

jessyratfink (author)  WilliamS195 months ago

I did list times - and power doesn't make as big of a difference as you think!

"Cook in the microwave for 50-60 seconds. (At home, it took me 60
seconds in a 600W microwave. In the test kitchen, 55 seconds in a 1000W gave me a good result.) Too
little time, and the cake will be wet on the outside. Too much time, and
it will become really crumbly. Also, cooking them individually is best."

I apologise! I wrote the note before I noticed that I needed to turn the page. I then clicked on delete for the note, but it did not delete. I read the cooking time, but stilll didn't see a power level.

Thanks for your reply.

Since this was a double post, see my above reply for why suggestion #1 is unnecessary.

I made this cake and I'm adding a photo of what I did. I made a mini layer cake out of it and frosted it with butter cream and sprinkled some finely ground walnuts on top! It turned out really good! Moist and delicious! I also added a half teaspoon of vanilla. Thanks for this recipe.

For vegans I guess use water and for egg substitute, use one tablespoon of ground flax seed, let it stoop in one tablespoon of warm water until it gets slimey...Will rise just like an egg I promise

I turned this recipe into a dark chocolate fudge brownie cake. All I did was increase the sugar to 3/4 cup, use half n half instead of milk, added a couple teaspoons of vanilla extract and 3 to 4 tablespoons of Hershey special dark 100% cocoa powder.
3/4 c. Sugar
3-4 tbsp. Cocoa powder
2 tbsp. Half n half
1-2 tsp. Vanilla extract

Make sure you thoroughly mix the cocoa powder in with the dry flour first or it will just clump. And for extra dense gooey brownie like cake, hold the baking powder.
CAKE! that looks and sounds yummy.
I must convince my parents to let me make this tomorrow!
