Preheat oven to 180°C (160°C fan-forced). Grease and line a 20cm cake tin with a removable base.
In a bowl, beat the butter and sugar together until light and creamy. Add eggs, one at a time, beating well after each addition. Scrape down the sides. Add ricotta, yoghurt, vanilla, and lemon zest, and mix well. Fold through the flour, baking powder, and a pinch of salt. Spoon the mixture into the tin and smooth out the top. Arrange apricot pieces, cut side up, over the top and sprinkle with brown sugar. Bake in the oven for 40-50 minutes.
Meanwhile, bring the syrup from the can to a boil with a few sprigs of thyme. Simmer for 5 minutes until slightly syrupy.
As soon as the cake is ready, pour over the syrup and leave to cool for about 30 minutes. Slice and serve with thick cream.
Enjoy!
