Add 1.5 cups of vanilla ice cream to your blender first. This prevents the liquid from splashing and helps create a thicker, creamier consistency.
Pour 0.75 cup of cold whole milk over the ice cream, followed by 0.5 cup of peach puree and 2 tablespoons of peach nectar. The combination of both puree and nectar creates the authentic Chick-fil-A peach flavor.
Add 0.25 teaspoon of vanilla extract and a pinch of salt to enhance the flavors and balance the sweetness, just like the original.
Blend on high speed for 30-45 seconds until smooth and creamy. Do not over-blend, as this can make the shake too thin. Stop when you reach a thick, milkshake consistency.
Pour the milkshake into a tall glass. If the shake is too thick, add 1-2 tablespoons of milk and blend briefly. If too thin, add more ice cream.
Top with whipped cream if desired, and serve immediately with a straw and long spoon for the best experience.
