Make Pistachio Pudding Cookies Recipe for tender, pastel-green cookies topped with a sweet glaze and crunchy pistachios.
Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper so they’re ready when the dough is made. Lining now keeps you moving smoothly — parchment squares cut to size, a clean rim of surface showing the painted pine wood beneath, no fuss.
In a large mixing bowl, beat the softened unsalted butter with the granulated sugar and packed light brown sugar until the mixture is pale, smooth, and creamy. Scrape the bowl a couple times so everything is incorporated — you’re aiming for a satiny, aerated base that will give the cookies a tender crumb.
Add the large eggs one at a time, beating well after each addition so the batter remains emulsified and glossy. Stir in the vanilla extract last, folding it in until the wet mixture smells warm and fragrant. The batter should look cohesive and slightly ribbon-y when the egg is fully integrated.
Whisk together the all-purpose flour, instant pistachio pudding mix, baking soda, and salt in a separate bowl until evenly distributed. Gradually add the dry mixture to the wet, mixing just until combined to avoid overworking the dough. Fold in the chopped pistachios so they’re evenly dispersed — the dough will be a pale pastel green, thick and scoopable, flecked with crunchy green bits.

Drop rounded tablespoons of dough onto the prepared parchment-lined sheets, spacing them about two inches apart so they can spread. Press a few extra chopped pistachios onto the top of each dough mound so you’ll have that toasted nut garnish after baking. The scoops should hold gentle peaks and show the pistachio specks on the surface.
Bake the trays for 10–12 minutes, watching for lightly golden edges while centers remain soft. Let the cookies rest on the baking sheets for about five minutes after removing them from the oven so they set gently, then transfer to wire racks to cool completely. The tops should be slightly matte with a soft sheen, indicating a tender, cakey interior.
Whisk together the confectioners' sugar with 2–3 tablespoons milk and the vanilla extract until the glaze is smooth and pourable but not runny. Adjust milk by the teaspoon — you want a glaze that forms a glossy ribbon when drizzled, thin enough to flow but thick enough to set into a pale translucent coating.
Drizzle the glaze over completely cooled cookies, letting it pool in little glossy ribbons across the pastel-green surfaces, then sprinkle a few more chopped pistachios over the top. Allow the glaze to set until just tacky before stacking or serving; present on a shallow matte ceramic plate or on a crinkled square of parchment for a rustic touch.
