Heat oven to 180C/160C fan/gas 4.
Butter a 2lb loaf tin and line the base
and sides with baking parchment.
Cream the butter and sugar until light
and fluffy, then slowly add the eggs with
a little flour. Fold in the remaining flour,
baking powder and bananas. Pour into
the tin and bake for about 30 mins until
a skewer comes out clean. Cool in the tin
for 10 mins, then remove to a wire rack.
Mix the icing sugar with 2-3 tsp water
to make a runny icing. Drizzle the icing
across the top of the cake and decorate
with banana chips.
