Preheat oven to 180°C (conventional oven). Grease a 10-cup bundt tin with a thin layer of DIY Cake Release and set aside.
Place the sugar and orange zest into the bowl of a stand mixer, fitted with a paddle attachment, and mix on low speed until well-combined.
Add the eggs to the sugar/zest mixture and beat on medium-high speed until the 'ribbon' stage is achieved.
With the mixer running, add the oil in a slow, steady stream until all of it is incorporated. Add the orange juice, as well as the orange blossom water and mix briefly to combine.
Sift together the flour, baking powder and salt, then gently fold into the batter by hand, using a large metal spoon. Once combined, pour the batter into the prepared tin and bake in the preheated oven for about 40 minutes, until a skewer inserted into the centre comes out clean, or with only a few, moist crumbs.
Allow the cake to cool in the tin for 5 minutes before turning out onto a wire rack to cool completely before serving.
