Ingredients

Scale

Cookie Dough

1.12 oz All-purpose flour
1/4 tsp Baking powder
14 oz Dark chocolate (chopped and divided)
1.5 oz Unsalted butter
2 large Eggs (room temperature)
4.6 oz Granulated sugar
1 tsp Vanilla extract
1/4 tsp Salt
2 oz Roasted salted pistachios (coarsely chopped)

Frosting

1 box (3.4 oz) Pistachio instant pudding mix (not sugar-free)
1/3 cup Milk
2.5 oz Unsalted butter (softened)
8 oz Powdered sugar
1 tsp Vanilla extract
1/8 tsp Salt
1/4 tsp Almond extract
2 oz Roasted salted pistachios (coarsely chopped, for rolling edges)

Instructions

Prepare Dry Ingredients: Sift the flour and baking powder together in a small bowl and set aside. Line two baking sheets with parchment paper for easy cookie transfer later.
Melt Chocolate and Butter: In a medium microwave-safe bowl, melt 10 oz of chopped dark chocolate and the unsalted butter by microwaving in 30-second intervals, stirring between each, until the mixture is mostly melted but slightly chunky. Stir until fully smooth and then set aside to cool.
Beat Eggs and Sugar: In a large mixing bowl, combine the eggs, granulated sugar, vanilla extract, and salt. Using a whisk attachment, beat on medium-high speed for 8-10 minutes until the mixture is pale, fluffy, and voluminous.
Combine Wet and Dry Mixtures: Fold the melted chocolate mixture and sifted flour gradually into the egg mixture on low speed, stopping once a few flour streaks remain. Gently fold in the remaining chopped dark chocolate and coarsely chopped pistachios until just combined.
Rest the Dough: Allow the dough to rest at room temperature for 10-15 minutes. This resting period helps meld flavors and improves the cookies’ height and texture during baking.
Preheat Oven & Scoop Dough: Preheat your oven to 350°F (175°C). Using a tablespoon, scoop the dough onto the prepared baking sheets, spacing them evenly to make 24-28 cookies for sandwiching.
Bake Cookies: Bake for 10 minutes until the cookies puff up and develop a crackly surface but remain soft in the center. Allow the cookies to cool on the baking sheets briefly before transferring them to a wire rack to cool completely.
Prepare Frosting Base: In a large bowl, sift the pistachio instant pudding mix. Add the milk and whisk briefly, then let the mixture sit for 5 minutes to thicken.
Make Frosting: Add the softened butter, powdered sugar, vanilla extract, salt, and almond extract to the pudding mixture. Stir on low speed to incorporate the ingredients, then increase to medium-high speed and beat until the frosting is light, fluffy, and spreadable. Adjust texture by adding more powdered sugar or milk if necessary.
Assemble Sandwich Cookies: Spread a generous amount of the frosting on the bottom side of one cookie, then sandwich it with another cookie. Roll the frosting edges in the coarsely chopped roasted pistachios to give a crunchy, flavorful finish.

Notes

Ensure eggs are at room temperature to achieve a smooth, airy batter.
Use quality dark chocolate (at least 60% cocoa) for a rich chocolate flavor.
Do not substitute the pistachio pudding mix with sugar-free varieties as it will affect the frosting texture and taste.
Resting the dough before baking helps the cookies maintain height and develop better texture.
Store assembled sandwich cookies in an airtight container at room temperature for up to 3 days.
For extra crunch, lightly toast the pistachios before chopping.
