Preheat the oven to 350°F.
Generously grease and flour a bundt pan and set it aside.
In a medium bowl, combine the milk, eggs, vanilla and beat until combined. Set aside the wet ingredients.
1 cup salted butter, 1/2 cup freshly squeezed orange juice, 4 large eggs, 1 teaspoon vanilla extract, 1 cup sour cream
Sift together the dry ingredients into a standing mixer or large bowl.
2 cup granulated sugar, 3 cups all-purpose flour, 1/2 teaspoon baking powder, 1/2 teaspoon baking soda
Combine the wet ingredients with the flour mixture, then add the orange zest.
1 tablespoon grated orange zest
Add the butter in one tablespoon at a time until well combined. Scrape down the sides of the bowl and pour the batter into the prepared pan.
Bake 55-60 minutes until a toothpick comes out clean. Remove from the oven and allow the cake to cool for 10 minutes in the pan before turning it out onto a wire rack to cool completely.
While the cake bakes, combine the sugar and juice in a saucepan and bring to a boil to dissolve the sugar.
2-3 tablespoons freshly squeezed orange juice, 1 cup powdered sugar
Reduce the glaze by half.
Allow the cake to cool on a rack for 10 minutes before turning out to a wire rack to cool.
Drizzle the glaze all over the cake once it is completely cooled.
