In a bowl, mix the flour, baking powder, salt and cardamom powder together.
In another bowl, whisk the mango puree, vegetable oil, sugar, and vanilla until well combined. Add this to the flour mixture and fold until just incorporated. Don’t overmix.
Transfer the batter to a greased bundt pan and bake in a pre-heated oven at 180C – 350F until the cake is cooked through and a skewer inserted in the middle comes out clean. This will take about 40 minutes.
Transfer to a cooling rack, dust with some icing sugar and serve warm or at room temperature.
