Honey Sponge Biscuit

  • 5 large eggs
  • 150 grams (5.3 ounces) granulated sugar
  • 70 grams (2.5 ounces) honey
  • 160 grams (5.6 ounces) all-purpose flour
  • 1 teaspoon baking soda
  • 45 grams (3 tablespoons) vegetable oil
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt

Soaking and Filling

  • 1 large orange
  • 25 grams (2 tablespoons) granulated sugar
  • 25 grams (2 tablespoons) water
  • 120 grams (4.2 ounces) prunes
  • 50 grams (1.8 ounces) walnuts

The Cream

  • 350 grams (1.5 cups) heavy sour cream
  • 150 grams (0.6 cups) whipping cream
  • 100 grams (3.5 ounces) powdered sugar


  • Mixing Bowl

    A large, high-quality mixing bowl ensures you have enough space to whip your ingredients to perfection without making a mess.

  • Hand or Stand Mixer

    For that optimal fluffy texture, a reliable mixer is a must. Gradually increase speed to achieve the best results.

  • Sieve

    Sifting the flour and baking powder together helps to avoid lumps and ensures a smooth batter.

  • Saucepan

    You'll need this for heating the honey and prepping the filling mixture. A non-stick saucepan works best.

  • Baking Pan

    Use an 18-20cm (7.09-7.87 inch) or two 16cm (6.30 inch) diameter baking pans for best results.

  • Spatula

    A silicone spatula is ideal for gently folding ingredients to maintain the batter’s volume.


Step 1

Step 1: Mix the eggs with granulated sugar and salt. Start whipping, gradually increasing the mixer speed. Whip for about 7 minutes until fluffy. Ensure your mixer bowl is clean and dry for the best volume.

Step 2

Step 2: Sift the flour together with the baking powder. This step helps prevent lumps and distributes the baking powder evenly.

Step 3

Step 3: Place the honey in a saucepan and melt until liquid. Add a teaspoon of baking soda and keep stirring over the heat for about a minute. The mixture will foam and acquire a caramel hue. Be careful not to burn the honey. Stir continuously.

Step 4

Step 4: Add the flour mixture to the whipped eggs and mix gently to maintain the volume. Use a spatula and fold the mixture to keep it airy.

Step 5

Step 5: Add the vegetable oil and honey mixture to the batter and mix gently. A gentle hand prevents knocking out too much air.

Step 6

Step 6: Pour the batter into a mold (18-20cm | 7.09-7.87 inches) or two molds of 16cm | 6.30 inches in diameter. Bake at 356°F (180°C) for about 30 minutes until a toothpick inserted comes out dry. Ovens vary, so keep an eye on your sponge.

Step 7

Step 7: Let the honey biscuit cool, wrap in plastic wrap, and refrigerate for at least 4 hours. Chilling makes it easier to handle and slice.

Step 8

Step 8: For the filling, remove the zest from half of the orange. Squeeze the juice from the whole orange into a saucepan; add water, sugar, zest, and washed prunes. Bring to a boil and cook for 2-3 minutes. Keep stirring to dissolve the sugar completely.

Step 9

Step 9: Drain the syrup, reserving it for soaking the honey biscuit. Cut the prunes into pieces. Toast the walnuts in a pan, then chop. Toasting enhances the flavor of the walnuts.

Step 10

Step 10: Whip the heavy cream with powdered sugar. Add the sour cream and mix at a low mixer speed until smooth. Don't overmix to prevent the cream from curdling.

Step 11

Step 11: Cut the sponge biscuit into 3-4 layers. Soak each layer with the reserved syrup, then cover with cream. Top with prunes and nuts, and alternate layers. Ensure even soaking to keep the cake moist.

Step 12

Step 12: For the final touch, you can choose to cover the entire cake with cream for a juicier result. For a more decorative option, use cream cheese for frosting.
