Slow Cooker Dessert

Making desserts in the slow cooker is a bit of a thing with me, in case you haven’t been here before. This slow cooker giant cookie with white chocolate and raspberries is my latest creation, inspired by my giant chocolate chip cookie.

The great thing about making a cookie like this in your slow cooker is that you can leave it to bake while you get on with other stuff. If you have a busy household like me that’s a top priority!

This recipe makes a thick and delicious giant cookie ideal for sharing for dessert. If you prefer it warm you can eat it straight from the slow cooker when soft, with ice cream and sundae sauce.

Or wait until it cools, slice and enjoy with a cup of coffee or tea. It’s also great reheated in the microwave for a quick treat.

  • 190 g plain flour
  • 0.5 tsp baking powder
  • 115 g butter at room temperature
  • 75 g caster sugar
  • 60 g soft dark brown sugar
  • 1 tsp vanilla extract
  • 1 egg
  • 75 g fresh raspberries sliced in half
  • 100 g white chocolate chunks


  • Grease the pot of your slow cooker and line it with baking paper. 
  • In a bowl, stir together the flour and baking powder.
  • In another bowl, cream together the butter and two sugars until light and fluffy.
  • Add the egg and vanilla extract and mix.
  • Stir in the dry ingredients.
  • It might look a bit dry but get your hands in and work it together so that it comes together like dough. When it is the right consistency the sides of the bowl will be clean.
  • Add the white chocolate chunks and mix through.
  • Add the halved raspberries and carefully mix through, avoiding crushing them.
  • Place the mixture in the slow cooker bowl, on the baking paper. Press it in so it is flat and even and reaches the edges.
  • Cook on high for 2-3 hours with a few pieces of kitchen roll under the lid to stop water dropping onto the dough.
  • The sides will start to come away from the pot when it is ready, and the top will still look a bit moist, but it will harden on cooling.
  • Take out the slow cooker pot and leave for a few minutes to cool.
  • Remove the cookie by pulling the sides of the baking paper. Place it on a cooling rack to cool. Or if you are going to eat it hot, add ice cream and sauce and dig in!


This recipe fits a 3.5 litre slow cooker.
Increase the quantities for a larger slow cooker as otherwise it will be too thin and might burn quickly.
If using a smaller slow cooker, the cookie will be quite thick and won't harden as well.
Timings: This took 3 hours on high in my slow cooker but you need to know your own slow cooker and whether it cooks quickly because all slow cooker vary.
So check your cookie regularly to look out for burning and if the edges are getting cooked make sure it is not burning. If it does, remove!

It looks fabulous. I’m always amazed at the things you manage to rustle up in your slow cooker!

Another wonderful Slow Cooker bake. I love raspberries and they do go very well with white chocolate.
