Preheat oven to 350 degrees F.
Grease a bundt pan and set aside.
In a small bowl, sift together the flour and baking powder. Set aside.
In a large bowl beat together the eggs with the sugar on medium high for about 2 minutes or until creamy and pale in colour.
Add in the oil, water, vanilla, lemon zest and juice and mix till combined.
Add the flour mixture to the egg mixture and beat until smooth and the batter falls into a ribbon like flow when the beaters are lifted.
Make sure to scrape down the bowl if using a stand mixer.
Pour the batter into the prepared bundt pan.
Bake for about 40 to 45 minutes or until the top is golden brown in colour and firm to the touch.
Alternately, you can insert a toothpick to check for doneness.
If the wooden toothpick inserted inside comes out clean, you'll know the cake is done.
Let the cake cool in the bundt pan for about 10 minutes.
Loosen the edges with an offset spatula or butter knife. Take care not to scratch the non stick finish of your bundt pan.
Gently invert onto a wire rack to release the cake and allow to cool completely.
When ready to serve dust with confectioners sugar, slice and enjoy!
