Quest Birthday Cake Protein Bars are chewy, coated protein bars made for a sweet snack, with 20g of protein and 4g net carbs per bar.
These bars bring a celebratory birthday cake flavor to everyday snack moments, without requiring a special occasion. Their individually wrapped format is made for on-the-go routines, whether you want a snack during a car ride, between daily activities, or after time at the gym. The chewy texture and coating make them a sweet-tasting option when a birthday cake craving strikes.
Each bar combines birthday cake flavor with 20g of protein, 4g net carbs, and 1g sugar. Quest makes the bars with dairy-based complete proteins that provide all 9 essential amino acids. They are gluten free and keto friendly, offering a protein bar option for shoppers seeking those features.
The pack contains 4 individually wrapped protein bars. Each wrapper keeps one bar ready to take along for a snack at the gym, during a car ride, or whenever you want a sweet bite. The single-bar portions also make it simple to keep the remaining bars for later.
Enjoy a bar as an on-the-go snack, a mid-day bite, or a sweet treat when you want birthday cake flavor. Each bar has 14g of fiber, and the recipe has no added sugars. The 1g sugar figure is the per-bar amount; no added sugars does not mean sugar-free.
Quest Birthday Cake Protein Bars suit people who want a portable protein snack with a celebratory cake flavor, plus shoppers looking for gluten-free and keto-friendly options. Their four individually wrapped bars are designed for convenient snacking rather than serving as a whole birthday cake or a meal.
