Rich, gooey and indulgent, Slow Cooker Marshmallow Brownies are just the best!
The marshmallows melt into the centre of the brownies, making them even more gooey and sticky, then you melt some more marshmallowy on top for a chewy layer to bite through.
Brownies are the perfect bake to make in a slow cooker, they are fudgy and dense and of course you can forget about them for a couple of hours.
Line your slow cooker with parchment/baking paper, and add a cloth/tea towel under the lid to catch drips and moisture, and your slow cooker is ready for baking.
I bake a lot in my slow cooker, in case you hadn’t noticed, there are loads more slow cooker baking ideas and recipes here and in my slow cooker archives.
Slow cooker marshmallow brownies taste great and are so easy to bake.
These are perfect for baking with kids too. Mine really love slow cooker baking and there is much less risk of them burning themselves.
Cut yourself a square and enjoy with a coffee. Share with your friends and work colleagues and you’ll be popular!
They would be great for a school or workplace bake sale too.

Slow Cooker Marshmallow Brownies
Ingredients
- 125 g butter
- 125 g dark chocolate broken into small pieces
- 2 medium eggs
- 150 g caster sugar
- 20 g cocoa powder
- 60 g plain flour
- 10 large marshmallows cut in half
Equipment
Instructions
- Chop the butter and chocolate up into small pieces and put in a bowl. Microwave on high for 1-2 minutes until melted. Allow to cool.
- Whisk the caster sugar and eggs together for 3-5 minutes using an electric mixer, until it looks thick and creamy.
- Pour the cooled chocolate and butter mixture over the egg and sugar mixture and fold it in gently until completely mixed.
- Sieve in the cocoa powder and flour and again fold in gently until completely incorporated, but do not overmix.
- Grease and line your slow cooker bowl with grease proof paper.
- Pour the brownie batter in.
- Add about 6 of the marshmallows, in pieces, on top.
- Cook on high for 1.5 to 2 hours or until just set in the centre. See my note below regarding cooking time.
- Half way through, add the rest of the marshmallows on top (the others will have sunk/melted into the brownies).
- Allow to cool completely before using the baking paper to remove from the slow cooker.
Notes

My slow cooker burns the outside before the middle is cooked if I use grease proof paper so I got come silicon cake tins and silicon cupcake molds (put paper cupcake cases inside these) now there’s no burning just yummy cakes and brownies.
Thanks for sharing the recipes. 🙂

Hi, may sound a really silly question but never tried anything like this before… Do I put the lid on the slow cooker or not?
bakingqueen74 says
Hi, yes the lid goes on, you can put a tea towel under it if needed to catch the drips and stop the top of the brownies going soggy!

I made these tonight but they didn’t turn out so great!followed the recipe, greased and lined the slow cooker pot, cooked on high until middle just set but the sides and bottom ended up burnt and stuck to the greaseproof paper!Any ideas where I went wrong or did I just cook it for too long?Feel if id taken it out sooner to prevent sides burning it wouldn’t have been cooked properly in the middle!!I got stuck into the middle of it with a fork to try it and its so good, lovely and moist and gooey its such a pitty it’s not like that throughout and cant be separated from the paper!!Would love to get these right!

Hi Amanda, it sounds like,your slow cooker cooks very hot, I do find some are hotter than others. I actually have one slow cooker I wouldn’t try this in as I bet it would burn in an instant! What size is your slow cooker? One good way to,stop it getting hot so quickly is to use a silicone pan within the slow cooker, on top of an upturned saucer so something like that. That way it kinds of steams but without the contact to the bottom of the pot to make it burn. If you can see my cream cheese brownies recipe I did that for that recipe, and it worked really well.
