Watermelon Crush (sugar-free): Adds bold watermelon flavor and sweetness without sugar, making the ice cream refreshing and fruity. (see alternative options below)
Unsweetened Vanilla Almond Milk: Acts as a creamy, low-calorie base with a hint of vanilla that complements the watermelon flavor without adding sugar.
Vanilla Whey Protein Powder: Boosts the protein content while adding a creamy texture, helping the ice cream set nicely.
Guar Gum: Serves as a thickening agent to improve the creaminess and reduce iciness, giving the ice cream a smooth, soft texture.
Vanilla Extract: Enhances the overall flavor by adding depth and balancing the sweetness of the watermelon crush.
Heavy Whipping Cream: Used as a mix-in, it provides richness and a luxurious mouthfeel, making the ice cream more indulgent while maintaining creaminess.
