Instructions

To Make the Cake

Step 1 Preheat oven to 325˚F. Spray a 9 x 5 baking pan with non-stick baking spray and line with parchment paper. Leave a 1 to 2-inch overhang beyond the edges of the pan for easy removal of the cake once baked.

Step 2 In a medium bowl, whisk together the flour, cake flour, baking powder and salt. Set aside.

Step 3 In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium high speed for 3 to 4 minutes. It will be light and creamy.

Step 4 With the mixer on medium low speed, slowly add the sugar until fully incorporated. Mix for 30 seconds. Add the eggs, followed by the egg yolks, one at time. Mix on low speed thoroughly between additions and scrape down the sides of the bowl as needed.

Step 5 Add the vanilla and mix to combine. Add the dry ingredients to the butter and egg mixture, alternating with the orange juice. Begin and end with the flour mixture. Beat on low speed only until just combined and a few streaks of flour remain.
