Put the flour, reduced-fat spread, granulated sweetener, caster sugar, baking powder, cooled coffee mixture, eggs and vanilla extract in a medium mixing bowl and beat together for 1- 2 minutes with an electric whisk until light and creamy.

Bake in the preheated oven for 20-25 minutes, until risen and spongy. To test if the sponge is ready, insert a small sharp knife into the centre; when the sponge is cooked the knife will come out clean. Leave the sponge in the dish to cool.
