In a bowl of medium size, stir together cocoa, flour, salt, and baking powder so everything's evenly distributed.
02 -
Using a big bowl, whip the butter with sugar until you get a fluffy, pale mixture. Blend in the egg yolk and vanilla until smooth.
03 -
Bit by bit, fold the dry mix into the wet until a soft dough forms. Be gentle with the mixing.
04 -
Wrap your dough in some plastic and pop it in the fridge for about 30 minutes—it'll be easier to handle when cold.
05 -
Turn on your oven to 175°C. Line a baking tray with either parchment or a silicone mat.
06 -
Roll the cool dough into little 2.5 cm balls. Coat each one liberally in finely chopped walnuts and space them about 5 cm apart on your baking tray.
07 -
Using your thumb or a tiny spoon, press softly into the center of each dough ball to create a little indent for the filling.
08 -
Bake for 10–12 minutes. The edges will set while the middle stays slightly puffed. Let them cool fully on the tray.
09 -
Mix cream cheese, icing sugar, and vanilla in a smaller bowl until it's smooth and creamy.
10 -
Once the cookies have cooled, fill the wells with the cheesecake mix using a spoon or piping bag.

For an extra touch, drizzle some melted chocolate over the cookies and sprinkle chopped walnuts if you'd like. Chill in the fridge for 20–30 minutes to let the filling settle.
