Preheat oven to 350ºF. Grease and flour 6 mini bundt pans or a small 7.5 inch bundt pan, and set aside.
In a medium large bowl, sift together all the flour, salt and baking powder ingredients, and whisk together. Set aside.
In a separate bowl, combine the the rest of the ingredients or orange juice, zest, oil, eggs, sugar and milk and whisk together until combined.
Slowly add the dry ingredient mix to the wet ingredients, and lightly whisk or fold until combined. Do not over mix. Adding dry ingredients too quickly or not folding them gently can also contribute to a sticky texture.
Pour the batter into the bundt cake pan(s) bake for 18-20 minutes or for 7.5 inch bundt pan bake for about 30-40 minutes until lightly golden brown on top and a toothpick comes out clean.
Cool in the pan on a wire rack for 10-15 minutes or until the pan is cool enough to touch. Invert the cake onto a cooling rack to cool completely.
Once cake is cooled, make the glaze.
