Ingredients

• 6 Eggs & 1 Egg white-room temperature, 180 ml Water
• 180 gr Flour, 25 gr Corn starch, ½ tsp Cream of tartar
• 1 tbsp Baking powder, ½ tsp Salt, Yellow food colouring
• 120 ml Vegetable oil, 250 gr Sugar, Strawberry jam
• 1 tsp Vanilla extract, 1 tbsp grated Lemon zest

Chocolate layer ingredients:

• 3 Eggs & 1 Egg white-room temperature, 100 gr Flour
• 90 ml Milk/Water, 140 gr Sugar, ½ tsp Vanilla extract
• 1 tsp Chocolate paste (optional), ½ st Cream of tartar
• 60 ml Vegetable oil, 2 tsp Baking powder, ½ tsp Salt
• 25 gr unsweetened Cocoa powder

Directions

• Preheat oven to 170°C, turn oven fan mode on. Place oven rack in the second lowest position. Line the bottom side of 2-3 square pans (29x23x4 cm) with parchment paper. If you only have 1 pan, then you should only make half of the yellow layer recipe first because the batter can’t wait that long. It is ok if you have 2 pans.
• For both kind of layers: Do it separately between the yellow & chocolate layer

1. Separate eggs white & yolk. Add 1 extra egg white into the other egg whites.
2. Beat egg whites with a mixer until foamy. Beat in cream of tartar until soft peaks form. Gradually add in 50 gr of sugar; beat until stiff peaks form. Set it aside.

• For the yellow layers:

1. Stir eggs yolk & food coloring into the vegetable oil; set it aside. Mix flour, corn starch, 200 gr of sugar, baking powder, salt, vanilla extract & lemon zest.
2. Make a well in the center of the mixture; pour in egg yolks mixture; combine well. Add in water; beat with a mixer/whisk until the batter smooth, with no lumps.

• For the chocolate layer:

1. Stir eggs yolk & chocolate paste into the vegetable oil; set it aside. Mix the flour, cocoa powder, 90 gr of sugar, baking powder, salt & vanilla extract.
2. Make a well in the center of the mixture; pour in egg yolks mixture; combine it well. Add in water; beat with a mixer/whisk until the batter smooth with no lumps.

• For both kind of layers: Do it separately between the yellow & chocolate layer

1. Add 1/3 parts the egg whites mixture into the yellow/chocolate batter. With a spatula, gently fold egg whites mixture in one direction. Fold in remaining egg whites, just until it blended.
2. Divide the yellow batter evenly & then gently pour them among 2 pans. Pour the chocolate batter into the third pan. Smooth the top. Bake for 10-15 min (until the cake rose). Turn the oven fan mode off, turn on upper heat & then cover up the pan with aluminium foil. Bake again for 25-30 min (until a toothpick inserted in the center of the cakes comes out clean).
3. Remove the pan from oven & turn the pan upside down on a wire rack. Let the cake cool down to room temperature. Turn the pan over. Run a blunt side of a knife, with one movement, between the sides of the cake & the pan. Remove cake from pans & peel the parchment paper.

• To assemble the cake: Place first yellow cake layer in the middle of a cake plate, bottom side up. Spread strawberry jam over the top of the cake evenly. Stack the chocolate cake; spread the jam evenly & then top with second yellow cake layer, bottom side down. Gently pressing the stacked cake to compact.
