One liter of whipping cream can be used to make about two 8-inch cakes. The following is the ingredient list and preparation steps for an 8-inch cake:

Ingredients list:

Whip cream: 500 grams

Eggs: 2

Cake flour: 50 grams

Milk: 25 grams

Corn starch: 10 grams

Baking powder: 3 grams

Fine sugar: 50 grams

Preparation steps:

1. Mix low-gluten flour, cornstarch and baking powder together, sift and set aside.

2. Beat the whipped cream until it turns white and has a clear texture, then add fine sugar and continue to beat until melted.

3. Beat the eggs, add milk and vanilla extract, and stir evenly.

4. Pour the whipped cream into the mixed flour, and use a spatula to stir evenly from the bottom up until there is no dry flour.

5. Pour into the prepared cake mold, smooth the surface with a spatula, put the cake into the preheated oven, and bake at 160 degrees for about 30 minutes.

6. After baking, take out the cake, let it cool slightly, then unmold and enjoy.

Note that the above is a method for making an 8-inch cake. The amount of whipping cream required for cakes of different sizes will also be different. At the same time, the density of whipping cream of each brand is different, so the amount of whipping cream required will also be different.
