125g granulated sugar
50g light brown sugar
125ml vegetable oil
2 A eggs, room temperature and separated
1 Tablespoons vanilla extract
1 teaspoon white vinegar

Option1: (preferred, to reduce the usage of food coloring)
1/2 teaspoon blue food coloring
22.5 ml blue pea flower water (80 blue pea flower +60ml water, cook til color strong enough)
115ml homemade buttermilk, room temperature

Option2:
125ml homemade buttermilk
1tbsp blue food coloring
                                                                                                                                                                                                                                                              
Cake:
1. Preheat oven to 180C. Lined a 6" cake pans and with baking paper at bottom. Set aside.
2. Whisk the flour, baking soda, cocoa powder, and salt together in a large bowl. Set aside.
3. Using a handheld or stand mixer fitted with a paddle attachment, beat the butter on high speed until smooth and creamy - about 1 minute.
4. Add the sugar and beat on high speed for 2 minutes until creamed together fairly well. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed.
5. Add the oil and beat on high for 1 minutes. The butter may not completely combine with the oil. This is normal and ok.
6. Add egg yolks and the vanilla. Beat on medium-high speed until combined. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Beat in the vinegar and the food colorings.
7. With the mixer on low speed, add the dry ingredients in two- three additions alternating with the buttermilk, beginning and ending with the dry ingredients, and mixing each addition just until incorporated. Do not overmix.
8. Whisk the egg whites using mixer in high speed mode until thick and hard peak form, about 2 minutes.
9. Fold egg yolk batter into meringue in 1 batch with a rubber spatula or wooden spoon.
10. Pour batter into cake pan. Bake for 60-65 minutes or until the tops of the cakes spring back when gently touched and a toothpick inserted in the center comes out clean. If the cakes need a little longer as judged by wet crumbs on the toothpick, bake them for longer. However do not overbake; your cakes may dry out.
11. Remove from the oven and allow cakes to cool in the pans set on a wire rack. Cool them completely.

Piping gel

Assembly:
1. Once completely cool, using a large serrated knife, slice a thin layer off the tops of the cakes to create a flat surface, then slide into 3 layers.

3. Cover the top with frosting. Place the second layer on top of the first. Repeat for the third layer, then ice the top and sides,
4. if desired, crumble the thin pieces of cake you sliced off in a large bowl. Decorate the sides and top edges of the cake with these crumbs.
