Microwave Golden Syrup Sponge Pudding (vegan mug cake)

My family are mad for mug cakes. They love them.

Of course, I'm always happy to oblige as they are so easy and quick to make and perfect if you have a sweet tooth.

Microwave sponge cakes are perfect for a late night craving too.

This is my best mug cake yet!

It makes a really generous portion size for one.

And a really easy recipe.

Microwave Golden Syrup Sponge Pudding with Vanilla Ice Cream

2 Minute sponge pudding

This crazy good sponge pudding bakes in the microwave in 2 minutes.

Just look at it!

The sponge is so fluffy and that sticky, syrupy sauce sinks right through the pudding to the bottom, so you get some toffee syrup with every spoonful.

It takes a couple of minutes to make the batter and syrup, then a couple of minutes to bake.

This vegan mug cake recipe is like magic!

And it's lighter than a treacle sponge pudding, but just as luxurious and gorgeous with a scoop of ice cream.

Is this a treacle sponge pudding?

Technically, it's not a treacle sponge pudding as it's made with golden syrup instead of dark black treacle (molasses).

However, often when people talk about a treacle sponge pudding or you are offered one in a bar or restaurant, it can be this lighter version made with golden syrup.

It's just one of those odd British things.

But don't worry, either are delicious, so don't be upset if it's not quite what you were expecting.

Microwave mug cakes & puddings

If you've not tried mug cakes or puddings yet, you really should.

All you need is a large microwave-proof mug and a few basic ingredients.

You don't need scales either, just a spoon to measure out and mix the ingredients.

They taste just as good as full-size puddings or cakes, but they are super quick.

They are awesome! The best thing!

Self-saucing pudding

This is a self-saucing pudding.

They are sometimes called a magic pudding too.

If you've not heard of them before, have a look at my Dark Chocolate Magic Pudding. It's a full size chocolate pudding, but the technique is the same.

So how does a self-saucing pudding work?

You make your cake batter, add it to the baking dish, then you pile the sauce ingredients on top.

Now the crazy bit.

You pour boiling water over it!

That's right, boiling water.

Once it's baked the sauce has magically appears at the bottom of the sponge.

You just have to hold your nerve and believe me when I tell you it works.

What you need to make microwave golden syrup pudding

This pudding is super easy to make and you don't need any fancy ingredients or equipment.


Here's the simple list of equipment you will need to make these vegan mug cake puddings.

  • A large microwave-proof mug
  • Tablespoon
  • Teaspoon


Here are the basic ingredients you will need.
  • Plain flour - all-purpose flour
  • Caster sugar
  • Baking powder
  • Salt - just a pinch
  • Oat milk - or your regular milk
  • Vanilla extract - extract is much nicer than vanilla essence, which is artificial
  • Vegetable oil - or another mild oil
  • Brown sugar - or demerara sugar
  • Golden syrup
  • Boiling water
The full printable recipe card with ingredients, method and tips is at the bottom of this page after the step-by-step photos.

Don't get all sticky with the golden syrup

Golden syrup is really sticky stuff and you and your kitchen can get in a sticky mess when you are baking with it.

I bet you know exactly what I mean!

So my tip is to rub a little oil over your spoon before you either dip it into the tin of golden syrup of squeeze the syrup out of a squeezy bottle.

The syrup will slide right off it, so less chance of getting sticky.

Can you use maple syrup?

Golden syrup gives the most wonderful caramel flavour, that you won't get from maple syrup.

However, if you can't get hold of golden syrup, you could use maple syrup for this microwave sponge pudding.

Not quite as good but still tasty.

Which type of mug is best?

You need a microwave-safe mug to make mug cakes and puddings.

I love my glass panda mug.
But before using a mug, check the base to check if it is suitable to be used in a microwave.
As well as making sure it's microwave safe, you also want to make sure the mug is big enough.
So choose your largest mug.
The one you would grab if you were going to make yourself a cup of soup or a big mugful of hot chocolate or cocoa.

Microwave power

The power can vary dramatically between different microwaves.

My microwave is 800 watts. 

Yours may be a bit less powerful or more powerful than mine and may need a little more or a little less time. 

Cook time can vary slightly from microwave to microwave so you can get different results and may need to give your mug cake a bit more or a bit less time.

After you make it the first time, if it's not perfect, you can tweak it the next time by changing the cooking time a little.

The sponge is ready if it is springy to the touch, but don't use your finger to test it, use the back of a teaspoon. The toffee syrup will be very, very hot.

Check out this guide to finding the wattage of your microwave.

A spoonful of sponge pudding with vanilla ice cream

How to serve golden syrup sponge pudding

Now wait a minute, don't just dig your spoon in, no matter how tempting the pudding looks.

Think about how to serve it.

Here are some ideas.

  1. A scoop of vanilla ice cream (we like Swedish Glace, which is suitable for vegans.
  2. Pouring vegan cream.
  3. Vegan squirty cream.
  4. Warm vegan custard.
  5. A dollop of whipped vegan double cream (Elmlea Plant Double Cream is supposed to be good, I've bought some but not tried it yet)
  6. A dollop of vegan banana ice cream.
  7. Naked, on its own, without a topping.

  11. Wow this recipe is so delicious and so fun to make. My kids will love this. Can't wait to whip this out. Thanks!

    1. Just make sure they wait a couple of minutes as it's very hot when just made.

  12. What a Lovely Food. I'll Definitely Try. Thank You.

  13. This looks delicious - I will put it on my to list - though it looks delicious for a cold winter's night - which is not quite with us but on the way

  14. Awesome for a cold winter's night. Next time I might cut down the caster and brown sugar - found it was a little bit too sweet, but still yummy :)

  15. Delicious and easy to make. It fixed my sugar cravings this evening.

  16. Tried this today, followed the amounts exact - came out very raw and watery for me. My microwave is 1110w.

    1. Doesn't sound like it's cooked unless you made a mistake with the measurements. Be careful measuring and try cooking for longer. If it is raw it is uncooked.

  17. Wow, such a surprise,
    Hank you

  18. Omg this was amazing and so easy to make. Never seen a recipe with boiling water poured over the top before. GENIUS! Used a small Pyrex dish and cooked for 1 min 45, as my microwave is more than 800W. A bit too much sugar / syrup for my taste, so will half it next time. Thank you :-)

    1. I am so glad you enjoyed it. It is definitely sweet, but such a treat.
