Perfect for Easter – Slow Cooker Chocolate Overload Cookie Cake!

Have you tried a cookie cake before? A huge, thick cookie baked in one pan, they are very naughty indeed, a delicious treat. In America they are sometimes called skillet cookies. A bit like the huge cookies you can get from Millie’s too.

I’ve made this one using a double chocolate cookie dough, and then topped it with more chocolates. I’ve used Maltesers, some leftover Milkybar mini eggs and a few micro eggs. Do you think it has enough chocolate in it??

You can bake these in a normal cake tin in the oven, or in a frying pan/skillet on the hob as well of course. I made this one in the slow cooker – then the chocolates can be added on top before the cookie becomes firm, without them sinking in or completely melting.

Prep Time: 10 minutes
Cook Time: 2 hours 30 minutes
Total Time: 2 hours 40 minutes


  • 200 g unsalted butter softened
  • 250 g light muscovado sugar
  • 2 medium eggs
  • 1 tsp vanilla bean paste
  • 300 g self-raising flour
  • 65 g cocoa powder
  • 1 tsp baking powder
  • 100 g chopped chocolate I used a mixture of milk and dark chocolate
  • 140 g chocolates for topping I used a mixture of Maltesers, Milkybar mini eggs and micro eggs


  • Cream the sugar into the butter until soft and fluffy.
  • Beat in the eggs and add the vanilla bean paste.
  • Sift the flour, cocoa powder and baking powder in a separate bowl.
  • Fold the flour mixture in bit by bit. I found at the end that I needed to use my hands to combine it together fully and form a dough.
  • Add the chopped chocolate to the dough and mix well.
  • Line a large round silicone baking pan with baking paper and spoon the dough in. Press the dough down with your fingers to fill the pan.
  • Place the pan in your slow cooker (I used a large 5.7 litre slow cooker that fits my silicone pan) and add two small jugfuls of water around the silicone pan.
  • Place the lid on the slow cooker, with a tea towel tucked in under the lid to stop the condensation dripping on the cookie cake.
  • Turn the slow cooker on low and cook for 2 hours.
  • After the two hours, add the chocolates on top. The top should not yet be firm, so you can press the chocolates into the dough.
  • Cook for a further 30 minutes on high.
  • Check that the dough has risen and seem firm around the edges. It won't feel firm in the middle but it will firm up as it cools, as cookies do.
  • Remove the silicone pan from the slow cooker and leave the cookie cake to cool completely. If needed (or if you just fancy it) you can add more chocolate on top before serving!

April’s Tea Time Treats Chocolate Recipe Round-Up!



OMG! What is this chocolate magic! I LOVE this, thanks so much for entering in to tea time treats too! Karen

oh my word this is just filthy naught gorgeous!… I love this. I am going to make it although mine will be slightly oval shaped as that’s the shape of my slow-cooker… thanks so much for the brilliant Simply Eggcellent entry x

This looks like such a great little blank canvas for easter eggs though I think I would probably love it without as well but it does look so gorgeous with them all huddled and melty on top

Oh wow! This is so scrumptious! You should have a second nickname SlowCookerWondersQueen! 🙂

Yummy! This chocolate cookie cake looks so delicious! Perhaps I should try to make it with any leftover Easter Eggs! x

It has never crossed my mind that it is possible to make cake in the slow cooker! Looks amazing 🙂

Wowsers! Small slices, I think!!

Another Slow Cooker triumph, Lucy! Hope you have a lovely Easter weekend.

This looks AMAZING!! Love the chocolate overload 😉 I’ve made ‘skillet cookies’ before but never tried them in the slow cooker, great idea!

Wow, I’ve never heard of this before- looks really interesting!
