  • 75 g butter softened
  • 80 g caster sugar
  • 1 egg
  • 180 g oats
  • 2 tsp baking powder
  • 70 g plain flour
  • 30 g cocoa powder
  • 2 tsp honey
  • 50 g chopped dates or raisins
  • 75 g milk chocolate broken up


  • Cream together the butter and the sugar and then add the egg and mix well.
  • Add the oats, baking powder, flour and cocoa powder and combine.
  • Finally, add the honey, dates and chocolate and mix well.
  • Lightly grease your slow cooker post.
  • Line your slow cooker pot using baking paper or a large cake case. 
  • Press the mixture into the baking paper or cake case, place the slow cooker lid on and cook on high for approx. 1.5 hours. 
  • When firm, remove from the slow cooker using the edge of the baking paper or cake case to pull it out.
  • Leave to cool and harden fully.
  • Cut into slices/triangles and serve.


  • The time required really depends on your slow cooker and whether it runs very hot ot not, so keep an eye on it and check for burning regularly.
  • I used a round 3.5 litre slow cooker for this recipe.
