- 8 oz white chocolate chips or chopped bar
Pastry
- 1/2 cup unsalted butter
- 1 cup water
- 1/8 tsp kosher salt
- 1 cup all-purpose flour 1 cup flour = 130 g
- 4 eggs room temperature
Chocolate Frosting
- 4 tbsp unsalted butter
- 4 oz semi-sweet chocolate
- 2 cup confectioners sugar
- 4 tbsp whole milk
- 2 tsp vanilla
- 1 pinch salt
- 1/4 cup pistachio pieces shelled, toasted, and chopped
Instructions
Pistachio Ganache Filling
- Grind the pistachios into a coarse powder.

- Heat the heavy cream in a saucepan over medium heat until it just starts to simmer.
- Stir in the ground pistachios and white chocolate. Remove from the heat and let sit for 5 minutes.
- Stir until the white chocolate is fully melted. Cover and refrigerate for 1-2 hours.
Pastry
- Preheat oven to 400℉. Grease 2 baking sheets or line with silicone baking mats. Gather ingredients.

- In a heavy saucepan, heat butter, water, and salt over medium-high heat until mixture boils.

- Reduce heat to low. Vigorously stir in flour all at once untill incorporated and a ball forms.

- Transfer to a bowl and let sit for 5 minutes to cool. Stir in eggs 1 at a time.

- Fill a pastry bag with the dough and cut off a 1-inch tip. Pipe the pastry into 12 rectangular-shaped mounds, 6 per baking sheet.

- Bake for 35 minutes, turning halfway through.
- Remove from oven and cut 1-inch slits in the sides of each pastry.
- Reduce heat to 375℉ and bake for an additional 10 minutes. Remove from oven and cool on a wire rack.
Chocolate Frosting
- While the eclairs are baking, make the chocolate frosting.

- Heat butter and chocolate over low heat until melted stirring with a whisk.
- Remove from heat and stir in sugar, milk, vanilla, and a pinch of salt.
- Allow to cool.

Assembly
- Allow the pistachio ganache to come to room temperature before use.

- Using a pastry bag, fill the eclairs with the pistachio ganache filling. It is much easier to fill using a small round piping tip instead of just cutting the plastic bag.

- Cover eclairs with chocolate frosting and sprinkle with toasted crushed pistachios. Enjoy!
