  • Slow Cooker


  • 120 g plain flour
  • 200 g 100 +100 caster sugar, divided
  • 25 g + 3 tablespoons unsweetened cocoa powder divided
  • 1 tsp baking powder
  • 175 ml milk
  • 80 ml vegetable oil
  • 1 tsp. vanilla extract
  • 170 g dark chocolate chips
  • 350 ml boiling water
  • ice cream and/or whipped topping or whipped cream for serving optional


  • Line with parchment paper in the slow cooker bowl and spray the parchment paper.
  • In a medium bowl, add the flour, 100g sugar, cocoa powder, baking powder and whisk to combine. Add the milk, oil, vanilla, and stir until just combined.
  • Pour the batter in the slow cooker into a smooth, even, flat layer. Scatter the chocolate chips.
  • In a second bowl, combine the rest of the sugar with 3 tbsp. cocoa powder. Whisk in the boiling water until smooth.
  • Carefully pour the hot cocoa-water mixture over the batter in the slow cooker. Do not stir. This mixture turns into hot fudge while the cake bakes; do not stir.
  • Cover and cook on high for about 1 1/2 to 2 hours, or until a toothpick inserted into the centre of the cake comes out clean.
  • Start checking at just over one hour to ensure you don’t overbake.
  • Remove the slow cooker bowl from the slow cooker and set aside for 5 minutes before serving while warm with whipped cream / or ice cream.
  • If you let it cool off the sauce will absorb into the cake.


You can do this cake in the oven in a ceramic dish with a layer of tin foil as a cover. Bake the cake at 170˚C for 1h.
