Heat milk, cream, and half the sugar in a saucepan over medium heat until hot but not boiling. In a separate bowl, whisk egg yolks with the remaining sugar until pale. Gradually whisk the warm milk mixture into the yolks, then return the mixture to the saucepan. Cook on low, stirring constantly, until the custard thickens and coats the back of a spoon (approximately 77°C). Remove from heat and stir in butter and vanilla. Allow the mixture to cool completely.

Once cooled, churn the custard in an ice cream maker according to the manufacturer's instructions. In the final minute of churning, fold in the crushed honeycomb candy. Transfer the ice cream to a container and freeze until firm for a minimum of 4 hours.

Preheat the oven to 175°C. Pulse pistachios in a food processor until finely ground, taking care not to form a paste. In a bowl, whisk together flour, baking powder, salt, and ground pistachios. In a separate bowl, cream softened butter with both sugars until light and fluffy. Beat in egg, vanilla, and almond extract if using. Gradually incorporate the dry ingredients until a uniform dough forms.

Roll the dough into 16 balls and flatten each to a 0.6 cm disk. Arrange on a parchment-lined baking sheet. Bake for 10–12 minutes until the edges turn golden. Cool completely on a wire rack.
