200gramswhite granulated sugar(granulated or caster)
Chocolate Icing Glaze
115gramsicing sugar(powdered/confectioner's)
15gramsunsweetened cocoa powder(Dutch-processed)
½teaspoonvanilla extract
30gramsbuttermelted
2-4tablespoonswarm water
Instructions
Preheat the oven to 170°C/340F. Grease and line a regular-sized loaf tin with baking paper that has overhangs allowing for easy removal of the cake once baked.
In a large mixing bowl, combine the hot water, cocoa, butter, and espresso powder. Whisk until all the butter is melted and the cocoa powder is incorporated with no lumps.
Pour the cake batter into the prepared tin and bake for 35 to 45 minutes. The cake is done with a cake tester or toothpick and comes out mostly clean.
Allow the cake to cool in the tin for 10 to 15 minutes before lifting it out and allowing it to cool completely on a wired cooling rack.
In a small mixing bowl, combine the icing sugar, melted butter, vanilla, and 2 tablespoons of warm water. If the icing is too thick, add warm water 1 tablespoon at a time, mixing in between each addition until a thick pourable consistency is achieved.
115 grams icing sugar, 15 grams unsweetened cocoa powder, ½ teaspoon vanilla extract, 30 grams butter, 2-4 tablespoons warm water
Pour the icing glaze over the cooled cake, allowing it to drip down the sides of the cake. Let the icing set a bit, slice, serve and enjoy!
All temperatures stated are for conventional ovens. Decrease the temperature by 20°C/25°F or gas mark 1 for "fan" or air-fryers.

Notes
White sugar can be substituted with brown sugar.
Hot water can be substituted with coffee (but leave out the instant coffee or espresso powder), or with a shot of espresso topped up with water to reach ½ cup.
Greek yogurt can be substituted with sour cream.
If you don't want to bloom the cocoa or find that bloomed cocoa is a bit intense for your liking, simply leave out the cocoa powder in this step and sift it in the dry ingredients in step 4.
Storage and Freezing
This cake can be stored in the fridge for up to a week in an airtight container. Individual slices, wrapped in cling film or plastic wrap can be frozen for up to 3 months. Defrost frozen slices in the fridge overnight and allow to come to temp before serving
