1. Prepare the ingredients, 4 large eggs and 5 small eggs. The white and the yolk are separated.
2. Mix the milk and corn oil and mix well.
3. Sift in the low powder and cocoa powder and mix evenly.
4. Break up the egg yolks, pour into the previous paste, mix well, and the egg yolk paste is ready. I like to use the back egg method to make chocolate cakes, which makes the taste more delicate.
5. The egg whites are added to the white sugar in three times, and they are beaten until they are foamed.
6. Mix the egg whites with the egg yolk paste three times. Preheat the oven to 160 degrees.
7. This baking pan is 28*28 cm, spread oil paper on the baking pan, pour the cake batter, vigorously shake it a few times, shake out large bubbles, and put it into the oven. Heat up and down at 160 degrees and bake for 18 minutes. (If you like to eat with the skin, heat up to 180 degrees, lower the heat to 150 degrees, and bake for 25 minutes).
8. After the cake is baked and left to cool, divide it into 6 equal portions.
9. Take three copies and place them on the bottom layer of the box for use.
10. The whipped cream is mixed with powdered sugar and salt until it is distributed. It is similar to thick yogurt, with faint lines but disappears quickly.
11. At this time, add a part of Oreo biscuits. The amount depends on personal preference. I added 30 grams. Keep playing, but don't hit too hard, it's ok to basically set the shape.
12. Prepare a large piping bag and put all the whipped cream in it.
13. Cut a small mouth on the piping bag and squeeze a layer of cream in a zigzag pattern.
14. Sprinkle a layer of biscuits on the cream. The size of the biscuits does not matter. After refrigerating, the biscuits will soften and the amount is arbitrary.
15. Then repeat the operation of the first layer, a piece of cake + a layer of cream + a layer of crumbled biscuit. The box cake is ready.
16. Seen from the side, you must dig to the end with a spoon when you eat. The rich taste is particularly refreshing.
17. Made three boxes.
18. Finished product.
19. Finished product.
