Preheat oven to 180 degrees celsius. Grease a round (6 inches) pan with butter and set aside.
Peel half of the lemon zest and place into a blender, add the eggs, milk, sugar, lemon juice and butter, then blitz.
Sieve the flour and baking powder into a bowl. Pour in the blended liquid mixture and mix together into a smooth batter.
Pour the batter into the greased pan, place into the preheated oven and bake for 45-50 minutes or until a skewer inserted comes out clean. Set the cake aside to cool.
In the meantime prepare the frosting by whipping the butter and cream cheese in a bowl. Add the icing sugar in 3 parts continually whisking until smooth and creamy but not runny.
Also, prepare the fruits, cut most of the strawberries in half, a couple into quarters and leave one or two whole. Cut the lemons into half and slice into half-moons. Set the fruits aside.
Now the cake should be cool. Slice into three layers, you cake do this with a slicer, leveller or just a knife. Lay the first layer unto a flat dish with a small scope of cream cheese at the bottom to help keep the cake in place.
Spread 1/4 of cream cheese frosting on top then place some halved strawberries all around the edges of the cake and place a few rough pieces in the middle with a little more frosting.
Place the second layer of cake on top and spread a generous amount of the cream and follow with the last layer of cake.
Place the remaining frosting on top and spread all over the whole cake (sides and top), it doesn't have to be perfect.
Now start placing the remaining strawberries on top, across the middle of a cake (making sort of a line across).
Finish by adding the slices of lemon to both sides of the strawberries. Slice and enjoy!
