Instructions

  • Mix in the lime zest and juice.

  • Sift in the flour and baking powder, and fold in.
    175 g self-raising flour, 1 tsp baking powder
  • Transfer the mixture into your lined slow cooker bowl.
  • Put the lid on, add a tea towel under the lid to catch drips, then cook on high for 1 hour. Then switch to low and cook for a further 40-50 minutes, or until a skewer comes out clean from the centre.
  • While the cake cooks, prepare your buttercream icing and lime drip icing. For the buttercream, cream the butter with the icing sugar until light and fluffy, then stir through the lime zest.

  • For the other lime icing, mix together the lime juice and icing sugar and thin it out if needed with the teaspoon of water, or as much as needed to reach your desired consistency.

  • Once the cake is cooked, trim any burnt edges, slice in half, then fill with the lime buttercream and spoon the other icing over the top and sprinkle with lime zest.

Notes

Cooking time really depends on your slow cooker. Every slow cooker is different. Once you know how long your slow cooker takes to bake cakes, use that as a guide. 
If cooking a slow cooker cake for the first time, check regularly (every 15-20 minutes) to make sure it isn't burning.
Use the tea towel under the lid to catch drips and stop the top getting wet and soggy.
Check the centre of the cake with a skewer or knife to see when it is cooked through.
If the top still seems a bit wet, cook for another ten minutes then check again.
