Easy Microwave Jam Sponge Pudding

An easy jam pudding made in a mug and cooked in the microwave in just 2 minutes.

Jam pudding is a good old-fashioned British pudding. It's usually served hot with hot custard or vanilla ice cream

The normal way to cook it is in a large pudding bowl or smaller pudding basins, covered with foil and baked in a water filled roasting pan in the oven. They are steamed as well as baked.

They can take anything from 45 minutes to 1 ½ hours.

My jam pudding takes 2 minutes to bake!


Two minutes to cook, yep that's it!

Two minutes and you have the most fluffy, soft sponge with a jam centre.


Oh and you can mix it in the mug or a separate bowl.

If you mix it in the mug, which is what we normally do, then you only have a spoon, measuring spoons and a mug to wash afterwards.

Compare that with washing up a mixing bowl, measuring spoons and cups or scales, a roasting pan, pudding basins, serving bowls and spoons and after all that clear up it takes over an hour to bake.

My microwave jam pudding wins every time!

I'm loving mug cakes and puddings right now.

So far I've made:

And if you're looking for a savoury mug dish try my vegan microwave mug macaroni cheese.

I'll bring you more mug recipes to try soon!


  • They are super easy to make
  • They are super quick to make
  • You can just make one, a single portion
  • I can quickly make a treat for my son or husband
  • I can have a treat and it's a single portion not a whole cake or pudding
  • They don't use up lots of ingredients
  • They are cheap to make
  • They are great for a last minute dessert
  • There's no fancy ingredients (I always have what I need to make them)
  • There's not a lot of washing up
  • They taste amazing

This is my husband's favourite mug cake.

After I made if for him the first time, he asked for it constantly.

I had to remind him it wouldn't be a good idea to get into the habit of having pudding every day.

So he took things into his own hands, got all the ingredients he thought would be in it and asked me for the recipe then made it himself.

Of course he declared his the best he'd had yet. Cheeky toad!

My mum has become part of our bubble (if you're reading this beyond 2020, just google the year and you'll soon know what I'm talking about), so me and the wee boy went to stay with her for a few days over the weekend. 

It was the first time seeing her for months. It was wonderful!

My husband was working and looking after the dogs, so happy to stay home, but what was his one concern?

Yep, that I was taking the sponge pudding recipe with me.

My husband isn't one for baking or cooking, so it's a strange thing to see him going into the kitchen, getting baking ingredients out and making himself a pudding.

He loves this recipe!

You'll see from the photo of my fridge above that I left him the recipe along with a warning not to eat it every night.

Hey, I'm just thinking of his waistline.

  1. Use a large mug, not a smaller tea cup. I mean you can try the smaller tea cup, but you might find half the pudding decorating your microwave. A good size mug or cup, that you might serve soup in is best.
  2. Adding sprinkles is always a good idea, but they are optional.
  3. If you're going to tip it onto a dessert plate or a bowl to serve, grease the mug first before adding ingredients and when it's ready, loosen the edges with a knife.
  4. You can mix the batter in the mug, add the jam at the end and push it under the batter (less dishes).
  5. Microwaves vary, your pudding may take a little less or a little more time to cook.
  6. You can add your favourite jam, any flavour.
  7. You could vary the pudding and add a dollop of chocolate spread, some peanut butter or some lemon curd instead of jam.
  8. You know your pudding is done when it is soft and springy to the touch, but no cake batter sticks to your fingertip.
  9. If it seems a little dry, cook it for less time next time.
  10. When you touch the top, if batter sticks to your finger in needs a little longer.

  • a mug - a decent sized mug
  • measuring spoons - there's not a great deal of weight in the ingredients, it's a small portion
  • a spoon - for stirring

  • plain flour - you can use self-raising flour instead, a pinch of baking powder will give extra rise but isn't essential
  • caster sugar - you can use brown sugar but it will colour your sponge
  • baking powder - for rise
  • salt - just a pinch
  • milk - dairy-free or dairy, just use what you have in the fridge
  • oil - choose a plain or mild oil
  • vanilla extract - never essence, it's just plain nasty
  • jam - your favourite flavour
  • sprinkles - optional

Try making your own jam and try this easy mixed berries jam made with frozen berries.

Making Microwave Jam Sponge Pudding - Step 1 - Dry ingredients - flour, baking powder, sugar, salt and sprinkles (in yellow bowl)

You can make the sponge batter in the mug itself or in a small bowl.

First add the dry ingredients - the flour, baking powder, sugar, salt and sprinkles if you are adding them.

Making Microwave Jam Sponge Pudding - Step 2 - Wet ingredients - milk and oil is added to the cake mix in yellow bowl

Give the dry ingredients a mix to combine, then add the milk and oil.

Making Microwave Jam Sponge Pudding - Step 3 - Vanilla is added to batter in bowl and whisked into batter

Add the vanilla and mix the cake batter until smooth.

Making Microwave Jam Sponge Pudding - Step 4 - Jam in clear glass mug with panda face

Add jam to your mug.

If you're mixing up the batter in the mug itself, just add a dollop of jam at the end and push into the cake batter so it is covered with batter.

Making Microwave Jam Sponge Pudding - Step 5 - Sprinkles  - cake batter is added to the glass mug over the jam and topped with sprinkles

If you mixed the cake batter in bowl, add it to the mug, covering the jam. If you mixed that batter in the mug, you're at this step already.

Top with a few extra sprinkles.

Making Microwave Jam Sponge Pudding - Step 6 - Microwaved pudding from the side and from above showing the jam breaking through the sponge

Pop in the microwave and cook for 2 minutes. When it's ready the surface of the sponge should be springy to the touch but you shouldn't have any wet batter on your finger tip.

Your microwave may be more or less powerful than mine (800w class E), so your cake may need a little less or more time. 

Stop it before the 2 minutes to do the fingertip test, if it needs more give it little bursts of power. 

Once you know the right time for your microwave you can make it that may each time. It should be roughly 2 minutes.

Making Microwave Jam Sponge Pudding - Step 7 - Serve - The final pudding served topped with vanilla ice cream

I recommend serving it with little dollops of ice cream while it's still warm. 

TIP: A melon baller makes the perfect size ice cream scoop for mug cakes.
WARNING: Remember that jam is hot, don't burn your mouth!

Easy Microwave Jam Sponge Pudding

An easy jam pudding made in a mug and cooked in the microwave in just 2 minutes.
Prep time: 2 MCook time: 2 MTotal time: 4 M


  • 4 tbsp plain flour (see notes if using self-raising flour)
  • 2 tbsp sugar
  • ½ tsp baking powder
  • pinch salt
  • 1-2 tsp sprinkles
  • 1 tbsp +1 tsp oil
  • 3½ tbsp milk
  • ½ tsp vanilla extract
  • 1-2 tbsp jam (depending how much jam you like)


  1. Add the dry ingredients to your mug and mix.
  2. Add the oil, milk and vanilla extract and whisk to a smooth batter.
  3. Add a dollop of jam and push below the surface.
  4. Microwave for 2 minutes.
  5. Top with a scoop of vanilla ice cream and serve.
  6. Enjoy!


Use a large mug or cup that is microwave safe.
If you only have self-raising flour you can use that. If using s-r flour, you can add a pinch of baking powder or bicarbonate of soda for extra rise, but that's optional.
Use a mild oil that won't flavour the cake.
You can use whatever milk you usually buy, vegan or dairy.
Add a few sprinkles to the top of the sponge before baking, it just makes it pretty.
If you are turning the sponge onto a dessert plate or bowl, grease the mug before adding the ingredients and once it's cooked, loosen the edges with a knife before turning the pudding out.
Mug cakes are best served on the day they are made and mug puddings are best served warm.

  1. Oh my gosh, I haven' had jam pudding in years! I used to have it as a kid and it's sooooo delicious! I love that you've made a microwave version, I have to make this!

    1. Yes same here, but this is so much easier. My husband and son love this one. Do try it.

  2. I am so excited to make this. I have such comforting memories of my mother making us jam pudding as a child. I always liked it with ice cream but my brother had to have custard. I can't wait to try this. Jill

    1. Yes I remember my mum making it too, although I am sure it came out of a tin. My mum did bake cakes, but I do remember some tinned puddings. This one is good with ice cream or custard. If you are turning it into a bowl to serve with custard, grease the mug before you start and loosed it with a knife before turning it out.

  3. There is nothing more comforting than cake in a mug! I can't wait to try all of your recipes.

    1. Yes they are rather good. I hope you try and enjoy them.

  4. This is so easy and simple to make. I absolutely love it.

    1. Thanks and yes it is super simple and quick. I hope you enjoy it.

  5. This is fabulous! So tasty and easy! I'll definitely be making again!

    1. I am so glad you enjoy it. Yes this recipe is a real keeper. So good.

  6. Sounds delicious - my mum used to make a pudding with jam on top but I don't have the patience for steaming a pudding - so I am going to try this. I have been making a brownie in a mug a lot - keep meaning to branch out with mug cakes but I love this brownie - but I must try this jam pudding for a kick of nostalgia.

    1. I know what you mean, steaming pudding is a faff and if you can do it this way in a couple of minutes .....

      I love mug brownies too. I must share the recipe for that one too.

  7. This looks great - and I'm so, so envious of you seeing your mother. It's ridiculous - it's been since March, and counting, and at the rate of idiocy here, it'll still be a while... But, I shan't complain. Here's to bubbles, good pudding, and all things we can do to survive this. Cheers!

    1. I know, it's been tough and I as so grateful. It does look more worrying over there, although down in England it isn't going to well either, they are opening everything way too quickly. Take care Tanita and say hi to David for me.

  8. Thanks for sharing, love the edition of the sprinkles :)

  9. I love small desserts! Just enought to satisfy your sweet tooth.

    1. Me too and it means you don't overindulge, well if you just make one anyway.

  10. I love a good mug cake recipe and this jam sponge looks delicious. So nostalgic too.

    1. Yes it does hark back to those jam sponge puddings we all had as children. I remember having them for school dinners. This version is so quick and tasty.

  11. Wow! Can't believe how quickly this came together in the microwave! Such an easy and delicious sweet treat.

    1. It is super quick and the results are amazing for such an easy wee pudding.

  12. This is a genius recipe! Perfect for when I need a bite of something sweet. Thank you for the recipe - now where'd you get that adorable mug?!?

    1. Thanks, I do hope you try it. The mug came from Asda. It's still in stock and really cheap.

  13. Fabulous! I love mug recipes. SO quick and easy. This one was wonderful. Can't wait to make it again

    1. Yes they are super quick. I am a real fan of them too now.

  14. What a great pudding recipe. Something new to try for my lil one. Thanks for sharing

    1. Yes these are great for kids. You can make them a treat super quick and retain superhero status.

  15. This is surprisingly good! I made a promise to myself to only eat food that can be prepared by me at home and I've been craving sweet treats all day. Didn't think this would be all that great but wow I really
    feel like I've had a treat. Used
    wholemeal flour and it worked fine. Defo be making this one again.
    Yum :D

    1. I am so pleased you enjoyed it. It's quite a task you set yourself, I have to say although I cook most nights I don't quite manage that.
