Jam and cream sponge

1. Preheat the Oven:
- Preheat your oven to 350°F (175°C). Grease and line the base of two 8-inch (20cm) round cake pans with parchment paper.

2. Prepare the Batter:
- Separate the egg whites and yolks into two large bowls. Make sure the bowls and beaters are clean and dry, as any grease or yolk in the whites will prevent them from whipping properly.

3. Whip Egg Yolks:
- Add the sugar to the egg yolks. Using an electric mixer on medium-high speed, beat the yolks and sugar until the mixture is pale, thick, and falls from the beaters in a ribbon (about 3-4 minutes).

4. Whip Egg Whites:
- Clean the beaters thoroughly and then whip the egg whites until stiff peaks form. This means the peaks stand up straight when the beaters are lifted out of the mixture.

5. Combine Mixtures:
- Gently fold the egg whites into the yolk mixture, being careful not to deflate the egg whites. Use a spatula and fold from the bottom up to combine.

6. Incorporate Flour:
- Sift the flour into the egg mixture in small portions, folding gently after each addition. Make sure there are no lumps of flour and the mixture is well combined, yet still airy.

7. Pour and Bake:
- Divide the batter equally between the prepared cake pans. Smooth the tops lightly with a spatula.
- Bake in the preheated oven for about 20-25 minutes, or until a toothpick inserted into the center comes out clean and the tops are lightly golden.

8. Cool the Cakes:
- Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Then turn them out onto a wire rack to cool completely.

9. Assemble the Cake:
- Once the cakes are completely cool, place one layer on your serving plate. Spread a generous layer of your favorite jam over the top.
- Spread a thick layer of whipped cream over the jam. Place the second cake layer on top and press down gently.

10. Add the Final Touch:
- Spread or pipe more whipped cream over the top of the assembled cake. You can add some fresh berries or a dusting of powdered sugar for an extra decorative touch.

11. Serve:
- Slice and serve your beautiful Jam and Cream Sponge Cake. Enjoy!
