1️⃣ Freeze the pistachio cream: Scoop 1 tbsp balls of pistachio cream onto a parchment-lined tray and freeze while you prep the dough.
2️⃣ Brown the butter: In a small saucepan over medium heat, stir until the butter turns amber with brown specks. Transfer to a bowl and chill in the freezer for 5 minutes.
3️⃣ Mix the dough: Whisk the cooled butter with both sugars. Add the egg and vanilla and mix well.
4️⃣ Add dry ingredients: Fold in flour, baking powder, baking soda, and salt until just combined. Stir in chocolate and pistachios.
5️⃣ Stuff the cookies: Scoop 3 tbsp cookie dough balls, flatten them, and place a frozen pistachio cream ball in the center. Wrap the dough around to completely enclose the filling.
6️⃣ Chill & bake: Refrigerate dough balls for 30 minutes. Preheat oven to 350°F (175°C).
7️⃣ Bake for 12-14 minutes or until the edges turn golden brown.
8️⃣ Shape & cool: Swirl a cup or biscuit cutter around each cookie to make them round. Let cool for 5 minutes on the tray, then transfer to a wire rack.
9️⃣ Enjoy! Drizzle with extra melted pistachio cream for an extra indulgent touch!
