This sponge cake is the perfect blend of fluffiness and nutritional density. By using whole wheat flour and pure cocoa, we increase the fiber and antioxidant content, while the use of extra virgin olive oil provides monounsaturated fats that are beneficial for cardiovascular health. Thanks to Stevia + Eritrytol 1:1 de Castelló, we achieve the ideal sweetness without refined sugars, making it a dessert suitable for diabetics, and with Baking powder we ensure an even rise and a light crumb. A pinch of Bonsalt balances the intense flavors of the chocolate and the aroma of the lemon.

Step-by-Step Instructions (Method)
1. Preparing the Wet Base
Preheat the oven to 170°C. In a large bowl, beat the eggs with the Stevia 1:1 with whisk until they double in volume and turn pale. Gradually add the milk and the mild olive oil while continuing to beat at low speed.
2. Dry Mixing Technique
In a separate bowl, sift the whole wheat flour with the Baking powder , the pure cocoa, the lemon zest, and the pinch of Bonsalt . Using a quality raising agent is vital to offset the weight of the cocoa and fiber, helping the sponge cake rise properly.
3. Baking and Finishing
Fold the dry ingredients into the wet ingredients with a spatula using gentle folding motions so you don't lose the air. Pour into a greased pan and bake for 25-30 minutes (do the toothpick test). Let cool on a rack before unmolding.

Flavor Enhancer: The pinch of Bonsalt brings out the deep notes of the pure cocoa without adding sodium, ideal for those who watch their blood pressure.
-
Irresistible Crumb: The Baking powder reacts with the natural acidity of the cocoa to create a fluffy crumb and prevent the sponge cake from becoming "dense".
