Slow Cooker Jam Sponge

Updated: May 1, 2026 by Jenny · 6 Comments

Jump to Recipe

Slow Cooker Steamed Jam Sponge Pudding is an absolute stonker of a comfort food pudding. Light but wonderfully filling it is a huge hug in a bowl and one of my favourite Sunday Lunch desserts ever. You can make it by steaming in a saucepan too. But I just love the ease of the slow cooker here. It is an absolute breeze.

What is a steamed pudding?

A steamed pudding is a mixture that is sweet or savoury and cooked with steam in a saucepan or slow cooker. The steam is created by water that surrounds the mixture which is cooked in a heatproof bowl.

The Christmas Pudding is an exception to the sponge rule, being rammed full of dried fruit and a generous splosh of alcohol.....hooray!

I find it super easy to cook mine in the slow cooker and I love to serve this jammy version for Sunday Lunch. It is always a crowd pleaser and another noise maker. It makes my Sunday every damn time, it's so lush.

The recipe card with full ingredients & instructions can be found at the bottom of the post.

Equipment Required

  • mixer, mixing bowl and hand held electric whisk or wooden spoon
  • scales
  • kettle
  • 2 pint pudding basin with lid or baking paper and silver foil square & string to secure
  • large spoon
  • spatula
  • slow cooker or saucepan

Recipe

I make my steamed jam sponge in my free standing mixer because that is always the way I roll but a large mixing bowl and electric hand held mixer is great too.

If you're feeling energetic then a plain old wooden spoon and mixing bowl will do the same job.

Ingredients and Substitutions

blank

150 grams (5.3 oz) Jam - I use my favourite strawberry jam

150 grams (5.3 0z) Butter - unsalted or you can use baking spread.

150 grams (5.3 oz) Flour - self raising or you can substitute plain with a tsp of baking powder

150 grams (5.3 oz) Sugar - Caster sugar refined or unrefined or you can substitute granulated

3 Large Eggs 

3 tbsp Milk - semi skimmed or full fat.

Method

  • Grease a 1.2 litre/2 pint pudding basin with butter. I use the plastic lidded bowls that are made for steamed puddings as I struggle/cannot be bothered with all the pleating and tying of string that is required for the ceramic bowls. Sometimes I miss the greasing out and it hasn't stuck yet but don't hold me to it.
  • Beat the butter and sugar together until pale and thickened a little. This takes a couple of minutes.

  • Whisk or beat in half the beaten eggs followed by half the flour for a couple of minutes. Add the remaining eggs and flour all at once as well as the milk. Whisk or beat again for another minute.
  • The batter should be a soft dropping consistency. Add a splash more milk if it's not.

  • Carefully spoon the sponge mixture into the bowl so that it stays on top of the jam.

  • Smooth over and place the lid or your coverings over the top.
  • Place the pudding bowl carefully in the slow cooker and pour just boiled water into the slow cooker bowl so that it comes ¾ of the way up the pudding bowl.
  • Place the lid on and cook for 3 hours on High.
  • If using a saucepan to steam your pudding then steam for 2 hrs 30 minutes.

  • To serve take it carefully out of the slow cooker or saucepan. Remove the lid and invert the pudding carefully onto a large serving plate. To do this I put the plate on top of the bowl and very carefully rotate so the plate is on the bottom and then slowly lift the bowl clear.

Cooking Tips

  • Grease your pudding bowl generously.
  • Use a plastic lidded pudding bowl for ease.
  • Add a splash of milk extra if needed to make sure the batter is a soft dropping consistency.
  • Reheat leftovers covered in the microwave
  • You can steam this pudding in a saucepan too for 2 hrs and 30 minutes.

Serving Suggestions

I serve it with either vanilla custard, vanilla ice cream or double cream (heavy cream).

    I have made this pudding several times, I’ve used different flavourings inc jam, lemon curd and chocolate. It’s become a firm favourite with my family. I’ve just put a syrup sponge pudding in the slow cooker to steam for tomorrows Sunday pudding. Very easy and seems to be foolproof. My daughter made the chocolate sponge last week for a family Sunday lunch , everyone loved it, the chocolate sauce complimented the sponge so well.

    I have made the pudding and let it cool unopened. I would like to reheat it. Can I just put it back in the slow cooker for a few hours?

      Hi,
      I have not done that before so am reluctant to say yes but I think it would work. You could also do the same in an oven I'm guessing but I tend to slice and reheat in individual portions in the microwave. But I will experiment with this as would be good to have the answer wouldn't it. I'll reply back to you when I have done it and write it into the recipe but I know that'll be later than when you could do with the answer! Thank you for reaching out and enjoy!
