Step 1

Preheat oven to 350°F. Whisk together baking powder, 2 ¾ cups of the cake flour, and ¾ teaspoon of the salt in a large bowl; set aside.

Step 2

Combine butter, granulated sugar, and brown sugar in the bowl of stand mixer fitted with the paddle attachment. Beat on medium speed until well combined and mixture starts to become fluffy and lighter in color, about 2 minutes, scraping down sides and bottom of bowl as needed. Add eggs, 1 at a time, and beat on low speed just until incorporated. Beat in sour cream, vanilla, 1 tablespoon of the orange liqueur, and 1 teaspoon of the orange zest. Gradually add flour mixture to butter mixture, and beat on low speed just until combined. Toss frozen cranberries with remaining ¼ cup cake flour in a medium bowl, and fold into cake batter. Coat a 10-inch Bundt pan generously with baking spray. Spoon batter into prepared pan, and spread evenly.  Bake in preheated oven until cake is golden brown and a wooden pick inserted in center comes out clean, 45 to 55 minutes. Cool cake in pan on a wire rack 15 minutes. Loosen sides of cake with an offset spatula; invert cake onto wire rack, and cool completely, about 1 hour.

Step 3

Meanwhile, whisk together powdered sugar, 1 tablespoon orange juice, and remaining 1 tablespoon orange liqueur, 1 teaspoon orange zest, and ⅛ teaspoon salt in a medium bowl. Add remaining 1 tablespoon orange juice, if necessary, 1 teaspoon at a time, for desired consistency. Spoon glaze over top of cooled cake.
