Turn your oven to 175°C (350°F) and get two 23cm (9-inch) round tins ready with baking paper at the base.
02 -
In a bowl, whisk the flour, cocoa, sugar, salt, baking soda, baking powder, and espresso powder until it's all blended nicely.
03 -
Using a mixer with the whisk attachment, combine the oil, eggs, and vanilla well.
04 -
Add buttermilk to your wet mixture and mix until smooth.
05 -
Slowly mix the combined liquids into the dry ingredients while pouring in the hot coffee.
06 -
Whisk everything until the batter is silky smooth—it'll be quite runny, so no need to worry.
07 -
Split your batter evenly between the tins. Use a scale if you’ve got one!
08 -
Bake for about 23 to 26 minutes. They're done if a skewer poked in the middle comes out clean.
09 -
Let the cakes cool completely in the tins before taking them out.
10 -
Take your softened butter and beat it until it's creamy—about 2 minutes should do it.
11 -
Slowly mix in the icing sugar, cocoa powder, cream, salt, and vanilla extract.
12 -
Start mixing your frosting on low speed, then whip it on high until it's light and fluffy.
13 -
If your cake tops are domed, trim them to make flat layers.
14 -
Layer the cakes with frosting in between, then cover the whole outside with the rest of the frosting.
15 -
Place your frosted cake in the fridge for 30 to 60 minutes to let it firm up nicely before slicing.
