Make sure all your ingredients are at room temperature (milk, eggs, orange juice, butter). Preheat your oven to 335℉
In the bowl of your stand mixer, combine together your flour, sugar, salt, baking powder and baking soda. Whisk and set aside.
In a separate container, combine your milk, orange juice, oil and eggs, extracts and zest. Whisk to combine.
Add your room temperature butter to your flour mixture and attach your paddle attachment. Mix on low until mixture resembles coarse sand.
Add in 1/3 of your wet ingredients mixture. Turn your machine up to medium and mix for one full minute. Mixture will look lighter in color and appear fluffier. Don't skimp on the time or the structure of your cake will not develop and it will collapse. Scrap your bowl with a spatula to make sure your batter is fully mixing at the bottom.
Add in your drops of food color, your citric acid then add in 1/2 of your remaining liquid. Let incorporate on low and then add in the rest of the liquid. Mix until just combined.
Pour batter into prepared pans (I like to use cake goop) and bake for 30-40 minutes until a toothpick comes out cleanly. Wrap and chill cakes in plastic wrap before torting and filling.
