Melt the butter and the chocolate, either in a saucepan or in the microwave at low, stirring every other minute. Transfer to a bowl and whisk together. Whisk in the instant coffee powder and the granulated sugar.
Whisk in the eggs, one at a time. Lastly, whisk in the flour. Transfer to a springform pan lined with baking paper.
Bake in the preheated oven at 170C (338F) for 20 minutes. Take out, transfer to a cooling rack and let come to room temperature. Best to make this step ahead and let the brownie cool overnight.

Place gelatin sheets in a bowl, cover with cold water and let bloom for 5 minutes. Pour 100 ml of cream into a saucepan and set on medium heat. When the cream is steaming and about to boil remove it from the heat. Whisk in the instant coffee and the drained bloomed gelatin. Cool to lukewarm (an ice water bath will speed up the process).
Combine the rest of the cream with the powdered sugar and start whisking at medium-low speed, either with a hand mixer or a stand mixer. When the cream is about to reach soft peaks, slowly pour in the cooled coffee and gelatin mix and mix in at low speed. The mixture will loosen only to get fluffy again, stop when at soft peaks again.
Place cooled brownie base back into springform pan. Line pan sides with a cake collar. Pour cream mixture onto brownie base and gently distribute all over with a spatula so it reaches all the edges. Do not handle too much or it may deflate. Transfer to the fridge to set for a minimum of 2 hours.

This cake must be stored chilled at all times. You can also store it in the freezer, then it will be easier to cut into portions. You can then enjoy it frozen or let it come to fridge temperature before serving.
