Method

  1. 1

    Heat the oven to 180°C (160°C fan). Grease and line a 20 by 30 cm tin. Toss the rhubarb with the 2 tbsp caster sugar and set aside.

  2. 2

    Beat the butter and 200 g sugar until pale and fluffy. Beat in the eggs one at a time.

  3. 3

    Fold in the flour, baking powder, xanthan gum and ginger, then the milk, until you have a soft dropping batter.

  4. 4

    Spoon into the tin and level the top. Press the rhubarb pieces lightly into the surface and sprinkle with the demerara sugar.

  5. 5

    Bake for 35 to 40 minutes, until golden and a skewer comes out clean through the sponge.
