Microwave cake

Featured
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.

Step 2: Mixing

In a medium bowl, melt your butter. Then add in the sugar and whisk until well combined.

Add in the baking powder, flour, eggs, and milk and whisk like mad. You want the mixture to be smooth and creamy. 

Step 3: Fill and cover

Spray your ramekins with cooking spray, and then fill them a little over halfway.

Tap the ramekins on the counter to knock out any air bubbles.

Cover them with a piece of saran wrap, leaving a small part of the edge unsealed so steam can escape.

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

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.

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.

Great recipe!

I just tried it. Using silicone muffin forms the basic recipe (1 egg) resulted in 6 muffins (6cm or 2 1/2 inch diameter).

Bake time was 1min 20s for all 6 together at 850W.

Cool recipe. I tried once creating a microwave cake but couln't get the timming right. You say 60 seconds, but at what power ? 700W ? 1000W ?
jessyratfink (author)  karlus1 year ago
My microwave at home is 600W, and the one in the test kitchen is 1000W - and there was only a five second difference in cooking time. And even five seconds under, they're still cooked through. :)
I don't like soy milk. But you taught me soy milk is the best for pies and cakes!! DELICIOUS!!!!! :-)
I didn't know that! Why is soy better than milk?
jessyratfink (author)  kazmataz1 year ago
I really couldn't tell you. I am sure there is some SCIENCE! happening somewhere, haha. But it is especially true with the chocolate pie I make - my mom and I substituted soy milk a few years ago while making it, and it came out ten times better than milk. Which is a big deal because we'd been religiously using 2% milk in the recipe for over a decade. :P
I'm about to try this (wish me luck). Where is the recipe for the chocolate pie (using soy milk) that you refer to? It sounds delicious - and I'd love to try it (with soy milk) as I too am lactose intolerant. Thanks!

Okay, I found the chocolate pie recipe (here: http://www.instructables.com/id/Chocolate-cream-pie/), and I just made the microwave cakes - the recipe was incredibly easy and fast, and the cakes came out just like in your gorgeous photo! Do you think it would it be okay to add some vanilla extract, just to give it a bit of a flavour boost? I will try adding some vanilla next time and see how that works. Thanks again for this great recipe. :)
jessyratfink (author)  irmab1 year ago
I think vanilla would be a good addition, but I'd put in very little. Maybe 1/4 teaspoon!

And I can't recommend that pie enough - it really might be the best recipe my family's got. :D
I don't know. I have only three kitchen instructables (one of them is a robot), so I think is magic. But Wednesday's chocolate pie was the best EVER, and Jessy told us the secret was the soy milk.

That looks awesome! I might even be able to handle this recipe. Now if you can come up withe a carrot or upside down pineapple version I would be even more tempted!

If you dont have Ramekins, you can use a coffee mug!

This intrigues me but let's get one thing straight here. I can burn salads and over boil toast. The kitchen is something I would love to get involved in but looks like a war zone as soon as I set foot in there. This however looks great and I figured maybe I could make something for my kids and not rely solely on my long suffering wife to provide the treats. I have one question though - what is cooking spray? I am in the Czech Republic and can't say I ever heard of such a thing. What is it for and is there an alternative? Sorry for what I am sure is as basic question as anyone could ask!
It's basically aerosolized oil. You could just wipe the sides of your ramekins with butter - it's just faster to spray them is all. Be sure to get the corners at the bottom and you'll be golden.
OK thanks. I shall definitely give this a whirl.

I don't have baking powder. Is there something I can replace it with, or could it possibly be left out?
jessyratfink (author)  GraceV961 year ago
You could try 1/4 teaspoon of baking soda instead - or do 1/4 teaspoon baking soda and 1/4 teaspoon cream of tartar if you've got that around.

Leaving it out won't hurt toooo much, it will just be flatter. :)

13 years ago my wife and I ended up without a stove or oven. The electric wok did not seem like an ideal method for some things, like cake. We enjoyed figuring out to make a quick cake ready in 15 minutes from a cake mix box was wonderful. I look forward to using your recipe. Caio for now.

Good morning from Laguna Beach, CA. Does anyone have any recipies for microwaving apples? I saw one once where you core the apple, add butter and cinimon and put in the microwave...but don't know amounts / time/ etc? Thanks. LagunaBeachMark@gmail.com
I used to do that for my kids all the time. We'd use the apple corer/slicer then lay out the slices on a plate. Sprinkle with cinnamon and a little sugar (their kids remember) and nuke for about a minute or two. (Who cares if they aren't cooked as long as they are hot) Seems like it was a 600-750 microwave. YMMV
