Pop pistachios into a food processor and blitz them into a crumbly consistency. Throw in the powdered sugar and soft butter, processing to blend. Slowly add heavy cream, one bit at a time, until it’s smooth. Leave it aside.

Set your oven to 350°F (175°C). Line a baking sheet with some parchment paper so the cookies don’t stick.

Mix the butter, white sugar, and brown sugar together until it’s nice and fluffy. Add one egg at a time, mixing well, then pour in the vanilla extract.

In another bowl, stir together the flour, cocoa powder, baking soda, and salt. Slowly add this into your wet mixture, blending gently until everything’s just combined.

Add the dark chocolate chunks and pistachios to the dough and fold them in until evenly distributed.

Take a scoop of dough, press it into a flat circle, and add a small blob of the pistachio filling in the center. Cover it with another flattened dough piece and press the edges together. Repeat with the rest.

Place the cookies on the prepared sheet, leaving space between them. Bake for about 10-12 minutes, until the edges are set but the middle still looks soft.

Let the cookies rest on the sheet for a couple of minutes, then move them to a wire rack to cool completely.
