A super light and fluff cake, with a subtle vanilla and lemon flavours and bursts of juicy raspberries. Enjoy this cake warm as a dessert, or cold for afternoon tea.
Preheat the oven to 180C / Fan 160C / Gas Mark 4. Grease and line a 20cm round baking tin.
Add the butter, olive oil and caster sugar to a large mixing bowl and beat together.
Add the eggs, vanilla extract and lemon zest and beat again until just combined.
Add the gluten free flour, baking powder and xanthan gum. Beat together until just combined.
Add the ricotta cheese and beat again until you have a smooth, very thick cake batter.
Fold in the raspberries carefully (I reserve a few to put on the top) and then pour into your lined cake tin. Smooth out and press the final raspberries into the top.
Bake for 55-60 minutes in the centre of the oven, until well risen and a skewer in the centre comes out clean.
Cool and dust with icing sugar to serve warm or cold.
