In a medium bowl, whisk together flour, sugar, baking powder, cardamom, and salt. Slowly stir in coconut milk until a shaggy dough forms.
Turn out dough onto a lightly floured surface and with lightly floured hands, knead until smooth, 4 to 5 minutes. Shape dough into a ball.
Spray a small bowl with cooking spray. Place dough in bowl. Cover and let rest for approximately 20 minutes.
In a medium Dutch oven, pour oil to a depth of 2 inches. Preheat oil over medium heat until a deep-fry thermometer registers 350°.
Divide dough in half and shape into 2 balls. Keep one dough ball covered in bowl, and place one dough ball on a lightly floured surface. Using a rolling pin, roll out dough ball to a 4½-inch circle. Using a sharp knife, cut dough circle into 8 equal wedges (triangles). Repeat with remaining dough ball.
Working in batches, fry dough triangles until golden brown, 1½ to 2½ minutes per side. Transfer to a wire rack placed on a rimmed baking sheet, and let drain. Lightly dust Mandazi with confectioners’ sugar. Serve warm.
