Servings: 12 slices


  • 10 yolks
  • 2 eggs
  • 3.5 oz | 100g sugar
  • 2.65 oz | 75g selfraising gluten free flour (I used Doves Farm)

For the blueberry glaze

  • 2.82 oz | 80g blueberries
  • 2 tbsp water
  • 3.5 oz | 100g sugar
  • 1.7 fl oz | 50ml water


  • Preheat oven to 355ºF | 180ºC and line a rectangular cake pan with parchment paper.
  • In a bowl, beat the yolks and eggs with the sugar for 15-20 minutes (speed 4) until you get a strong and bulky eggnog. The dough will thicken and turn light yellow and will be ready when it doesn’t drain from the mixer blades.
  • With the mixer at a minimumm(speed 1) or with a spatula, slowly add the flour until completely blended in the dough.
  • Pour the batter into the pan and bake for approximately 15-20 minutes. The sponge cake should be moist and slightly undercooked.
  • In a small saucepan, place the blueberries and cook over low heat for 5-10 minutes, stirring frequently. Transfer to a food processor or blender and grind until you get jam. Set aside.
  • In the same saucepan (don't worry if it stains), add the sugar and water and let it boil for 5 minutes. Remove from heat and stir with a wooden spoon until the sugar is translucent. Add the blueberry jam and mix well.
  • Remove the sponge cake from the oven and cover it immediately with the icing: with a spoon or a brush, spread the syrup over the cake making back and forth movements until the gaze is opaque.
  • Let dry, unmold and top with blueberries.


On the low FODMAP diet we can eat up to 1.41oz |40g of blueberries (fructans). The recipe calls for twice as much so you can eat up to half the sponge cake.
* if you don't have self-rising flour, you can use gluten-free flour + 1/2 teaspoon of baking powder.
