Combine the oil, sugar, cardamom and rose water in bowl. Using a hand mixer, mix on medium for 2-3 minutes until light and creamy.

Sift chickpea flour into the bowl and beat on low for 1 minute until the dough is no longer sticky.

Dust your work surface with some chickpea flour and knead the dough for 10 minutes until it is more workable. The dough is very crumbly.

Wrap tightly in plastic wrap and set aside for 2 hours. Do not refrigerate.

Preheat oven to 300 F and line baking tray with parchment paper.

Roll out the dough on a dusted work surface until it is ¾-inch thick. Cut out cookies using a 1-inch clover-shaped cookie cutter and place the cookies on the baking tray, spaced 1 inch apart. Re-roll and repeat until all the dough is used up.

Sprinkle chopped pistachios on top of each cookie.

Place cooking tray in middle rack and bake for 15 to 20 minutes, until the cookies turn a light golden colour.

Remove cookies from oven and let it cool on tray for a few minutes. Then carefully transfer to a wire rack to cool completely. Be careful when you transfer the cookies as they crumble very easily.
