Preheat the oven to 165C .

To make the base, put all the ingredients for the base in a food processor and pulse to cut the butter into the flour.

Next, using your hands just press the dough evenly onto the base of the tin.
Press well down into all the corners and sides then bake until it is golden brown all over.
Once cooked, remove from the oven and allow to cool while making the Snow Cake batter.
Beat the butter and sugar in the bowl of an electric mixer until light and fluffy.
While it is beating ,sift together the flour, salt and baking powder. Then add the coconut.
When the butter is light and fluffy, add the lemon zest and mix again, to scrape the sides of the bowl and the bottom to ensure everything is well mixed.
Add the eggs one at a time, beating well between each addition.
