Add plain vinegar or lemon juice to room temperature milk. Mix well. Rest for 10mins. Buttermilk is ready when it curdles.
I recommend weighing all the ingredients instead of measuring with cups for perfect results every time.
Sift all the dry ingredients together, the flour, cocoa powder, baking powder, baking soda and salt. Add the sugar. Mix well.
Use a Large sized Egg for a fluffy softer texture. Mine was around 73g with shell.
In the same bowl, add a large egg, oil, vanilla essence, buttermilk. Mix. Add hot water mixed with instant coffee at the end. Mix well.
Grease a baking tin with oil. Place a parchment paper at the base. Dust the sides with cocoa for smooth edges. I used an 6 Inch Round Tin of 2.2 Inch Height. You can use a 7/8/9 Inch tin, Baking time & Height of the cake will vary.
Bake @160C 65-70 MINS or till a toothpick inserted comes out clean. Allow to cool 10mins in the tin before de moulding. Loosen the sides first then reverse it in a plate.
Level out the dome of the cake. Use the reverse side. Once cool, refrigerate the cake.
I used Dark chocolate chips. Either measure 1/3 Cup if you dont have weighing scale or measure out 50g in a microwave safe bowl or pyrex glass.
Add 50g of Heavy Cream to the chocolate chips. Microwave for 60 secs, mix well. Allow to cool completely.
Pour the cooled Ganache on the chilled cake. Decorate with cherries or strawberries.
Bon Appetit!
