Preheat the oven to 180°C (350°F). Line five 10 centimeter (4 inch) spring-form cake tins with baking paper.
Put the butter and sugar in an electric mixer fitted with the whisk attachment. Whisk on medium–high speed until fluffy, about 5–8 minutes.
Meanwhile, sift the flour and salt together.
Once the butter mixture is fluffy, add the eggs, one at a time, and whisk until combined.
Add the milk, lemon zest, lemon juice, honey and olive oil and whisk until completely incorporated. Add the sifted flour and slowly whisk until a batter is formed.
Spoon 190 grams (6 3/4 ounces) of the batter into each cake tin. Arrange thin slices or pieces of fruit on top.
Bake the cakes for 35–40 minutes or until a skewer inserted into the centre of each one comes out clean.
Warm the honey in the microwave for 10–20 seconds to loosen it.
Drizzle each hot cake with some of the honey and use a pastry brush to brush it over the top of the cake.
Allow the cakes to cool a little before removing them from the tins and brushing them with more honey.
