This recipe is adapted from Hannah Mills who has been writing baking books for years and rarely fails to impress. It needs a stand mixer to get the creamy consistency that’s needed to create a lovely, light cake. It only takes about 10 mins to get the batter into the tin and oven ready so it’s quick and very tasty.
There’s no butter used which keeps it low fat and I’ve reduced the sugar quantity to help make these squares even better for you. As lime is generally sweeter than lemon, you can reduce the sugar without it impacting too much on the overall sweetness.
