Line the 3 cake pans with baking paper at the bottom by smearing some butter on the pan first and stick the cut pieces of paper on. Preheat the oven at 175 ℃
Mix 130 g Cake Flour, 225 g Sugar, ½ tsp Salt, ¾ tsp Baking Powder, ¾ tsp Baking Soda in the stand mixer bowl until combined. If you don't have a stand mixer, just use a big bowl and mix everything by hand.
In a separate bowl, bloom the cocoa by combining 90 g Hot Coffee and 40 g Cocoa Powder and mix. It should smell nice like hot chocolate. Then, add 120 g Creme Fraiche and ½ tsp Vanilla Paste to the bowl and mix well to combine.
In another separate bowl, whisk 3 Eggs together.
In the stand mixer bowl with the mixed dry ingredients, add 90 g Oil and half of the cocoa coffee mixture at low speed until the flour is well coated in liquid. Then increase the speed to medium to mix until smooth and pasty. (~30 secs)
Add in the eggs and the other half of the cocoa coffee mixture. Continue to mix at medium speed until it looks glossy and silky. (~1 min)
Pour the batter into the 3 lined pans. (275~290 g each)
Bake for 20 to 25 mins. Start checking at 20 by inserting a toothpick or cake tester in the center, and if the toothpick comes out clean with no batter sticking to it, it's ready.
Remove the cake from the oven and let cool in the pan.
