Preheat your oven to 350°F (180°C). Lightly coat the madeleine pan with cooking spray.
In a separate bowl, whisk together the flour, baking powder, and salt. Combine eggs and sugar in a large bowl and set aside.
Pour the melted butter into the egg mixture. Add vanilla extract and honey, then mix well.
Gradually add the flour mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
Gently fold in the chopped pistachios until evenly distributed in the batter.
Allow the batter to chill in the refrigerator for at least 30 minutes.
Then, Spoon the chilled batter into the prepared madeleine tray, filling the madeleine molds about 2/3 full.
Bake the pistachio madeleines in the oven for 10-12 minutes or until the edges are golden and the centers spring back when lightly touched.
Allow the madeleines to cool in the pan for a few minutes before transferring them to a wire rack to cool completely. Enjoy your delightful Pistachio Madeleines!
