In one big bowl, combine flour, sugar, cocoa, salt, baking powder, and baking soda by whisking. In another smaller bowl, beat together buttermilk, eggs, melted butter, and vanilla until combined. Slowly blend the wet mix into the dry mix. Stir in the hot water until smooth.

Spoon the batter into your prepared mini cake trays, filling each about 2/3 full. Pop them into the oven and bake for around 18-20 minutes, or until a toothpick slides out clean. Let them fully cool in the pan before moving them to a rack.

Warm the heavy cream in a little pan on medium heat till you see it start to simmer. Pour it straight over the chopped chocolate and mix gently until it’s smooth and melted. Let it cool for a moment so it thickens slightly.

In a chilled bowl, beat together the cold cream, powdered sugar, and vanilla until it firms up into peaks.

After the cakes cool, carefully slice them in half horizontally. On one half, spread some whipped cream, then add the top layer. Spoon the ganache over the cake tops and let it cascade down the sides.
