Finally - protein feels like a celebration.

Our Birthday Cake Protein Pastry layers delicious vanilla icing, gooey cake-style filling, and a shower of confetti sprinkles over a soft, bakery-fresh bite. The only thing left out is the sugar crash.

Under the frosting, our iconic protein dough delivers the texture you crave and the macros you want: 20g of protein, just 1g of sugar, only 4g net carbs, and 180 calories per pastry. It’s gluten-free, keto- and GLP-1-friendly, and ready when you are.

Our Legendary Protein Dough

Soft, chewy, and loaded with protein – our unique dough is the result of tireless innovation and obsession from the Legendary R&D crew. We’re fanatics when it comes to texture and experience.

Micellar Casein, Whey Protein Isolate

This protein duo was specifically selected for its ability to support the building of healthy muscles and deliver the Legendary flavor experience that we demand. In addition, protein is the most satiating of the macronutrients, which helps to feel full and satisfied.

Collagen Peptides

A complementary protein source that also supports connective tissue, hair, skin, and nails. The amount of collagen that we use is similar to levels found in beef and delivers a full amino acid profile.

pCAL

At Legendary, we obsess over pCal: which is the percent of calories that come from protein. Having a higher pCal% means that a food delivers more of its calories from protein, relative to carbs and fat.

pCal can be easily calculated with the following steps:

1) Locate the total grams of protein in a product
2) Multiply that number by 4 (there are 4 calories in every gram of product)
3) Divide that number by the total number of calories
4) All done!

Using Legendary Protein Pastry as an example:

1) 20g Protein x 4 Calories = 80 Calories
3) 80 Calories from Protein / 180 Total Calories = 44% pCal
