Method
step 1:
Grease a 10cm x 20cm (base measurement) loaf pan and line the base and sides with baking paper, allowing the 2 long sides to overhang.
Step 2:
Combine the flour and sugar in a large bowl. Add the buttermilk, butter, eggs and banana. Stir to combine. Stir in the date and walnut. Spoon the mixture into the prepared pan and smooth the surface.
Step 3:
Place an upturned heatproof saucer or ramekin in a slow cooker. Place loaf pan on the saucer or ramekin. Bake for 3 hours on high (or 5 hours on low) or until a skewer inserted in the centre comes out clean. Set aside in the pan for 10 mins before turning onto a wire rack to cool.
Step 4:
Cut the loaf into slices. Serve with caramelised banana and extra butter.
