Step 1: Prepare the Butter
Start with softened butter. It should be at room temperature but not melted. Place it in the bowl of a stand mixer fitted with a paddle attachment. Beat on medium speed for about 1 to 2 minutes until light and creamy.

Step 2: Add the Powdered Sugar
Gradually add the powdered sugar, one cup at a time. Mix on low speed at first to prevent a sugar cloud in your kitchen. Once incorporated, increase the speed to medium and continue mixing.

Step 3: Add Flavor Ingredients
Add the orange zest, freshly squeezed orange juice, flattened orange soda, and vanilla extract. Mix until fully combined. The aroma at this stage is bright and sweet.

Step 4: Add Cream for Texture
Pour in the heavy whipping cream and continue mixing until the frosting becomes smooth and fluffy. If the texture is too thick, add a teaspoon of cream at a time. If too thin, add a small amount of powdered sugar.

Step 5: Add Color if Desired
For a more vibrant orange appearance, add 1 to 3 drops of orange food coloring. Mix until evenly blended.

Step 6: Whip Until Perfect
Beat the frosting for an additional 1 to 2 minutes on medium high speed. This creates a light, airy texture that spreads and pipes beautifully.
