In a mixer bowl, combine the oil, sugar, cardamom and rose water. Mix on medium 1 minute until creamy.
Add chickpea flour into the bowl and beat on low 1 minute until the dough is no sticky.
Now you can use a food processor or knead the dough yourself, about 10 or more minutes until you can form a ball.
Cover the cookie dough with a plastic wrap and set aside for 30 minutes or so.
Preheat the oven to 180C and line baking tray with parchment paper.
Roll out the dough on a dusted work table - 5mm thick.
Cut the cookies using a cookie cutter and place them on the tray.
Sprinkle pistachios on top of each cookie.
Bake for 15 to 20 minutes, until the cookies turn golden.
Let them cool and enjoy. :)
