Preparing the Pate a Choux Dough:
Preheat the oven to 425°F. Line two large baking sheets with parchment paper or silicon mats.
To make the dough: pour the water into a medium sized saucepan. Add the salt and butter. Cook over medium heat until the butter is melted and the mixture starts to boil.
Whisk in the flour, then switch to a spatula once it’s incorporated. Cook for about 1 ½ minutes, until a dough ball comes together.
Remove the dough from the heat, transfer into a mixing bowl, and set into the refrigerator for about 20 minutes to chill. The dough needs to cool to room temperature.
Once the dough has cooled, it’s time to add the eggs. Using a mixer on medium speed, add the eggs, one at a time, mixing well after each addition. Once all the eggs have been added, continue to mix for 2 to 3 minutes, until the batter is smooth.
Transfer the dough into a pastry bag tipped with a large, round tip; I use Ateco tip #806.
Baking Instructions:
Pipe 1 to 1 ½-inch dollops of dough onto the lined baking sheets, spacing them about 2 inches apart. The puffs will increase in size while baking.
Pipe each dollop from the top, swirling the tip around at the end so the dough doesn’t stick up or have a pointy top.
If you have two oven racks, position them centered and above; you can bake both sheets at the same time.
Bake the profiteroles at 425°F for 10 minutes, then reduce the oven temperature to 375°F and continue to bake for an additional 35 minutes, until the puffs are a deep, golden color. DO NOT OPEN the oven during the baking process! Cold air will cause the puffs to fall flat.
Once baked, remove the puffs from the pans onto a cooling rack to cool completely before filling.
Making Pistachio Filling:
Place the shelled, roasted pistachios into a food processor or blender. Pulse until the nuts are finely ground. Pour in the Irish cream and pulse again for a few minutes. Set this mixture aside for now.
Place the softened butter into a mixer bowl and beat on medium speed for 8 to 9 minutes, until the butter is creamy and fluffy.
Add the softened cream cheese and beat again for 4 to 6 minutes, until it’s well combined with the butter. Add the powdered sugar, vanilla, and sea salt. Beat for 5 to 6 minutes, until the frosting is fluffy and creamy.
Last, pour in the pistachio and Irish cream mixture. If desired, add a few drops of green food coloring. Beat the filling for 1 to 2 minutes, until the pistachio mixture is well incorporated.
Keep the filling chilled until ready to fill the cream puffs.
Filling & Garnishing the Cream Puffs:
Once the profiteroles have cooled, use a small, round cake decorating tip to punch small holes in the bottom of each puff for adding the filling. I use Wilton tip #12.
So it’s easier to fill the puffs, transfer just half the filling into a pastry bag tipped with a small, round tip (Wilton #12). Add more filling to the bag as needed.
Pipe filling into each profiterole until completely full and a little bit of the filling comes out the bottom. Wipe off the excess.
Place the dark chocolate melts into a small bowl, then melt the chocolate in the microwave or over a double boiler.
Dip each cream puff into the chocolate, covering it about three-quarters of the way. Place the chocolate covered puffs onto a wire rack. While the chocolate is still wet, sprinkle finely ground pistachios over the top to garnish the cream puffs.
Serving & Storing:
Once the chocolate has set, you can enjoy these delicious pistachio cream puffs!
For overnight storage, place the cream puffs into an airtight container and into the refrigerator. They will keep well in the fridge for 3 to 4 days. For longer storage, freeze the cream puffs in a single layer on a baking sheet. Once frozen solid, store them in a locked bag or sealed container. Thaw in the refrigerator before enjoying.
