With the 4th of July quickly approaching, it’s time to plan the healthy desserts for your celebration. And it wouldn’t be an Independence Day barbecue without a flag cake, so I present you this Protein Flag Cake!


I remember the first time I saw this type of cake. It was part of the coupon insert in the Sunday newspaper. And I was amazed! I was probably 10 or 11 years old, and I remember thinking, “Whoever thought of this brilliant idea?!?” And since then, I’ve seen this kind of cake every year for July 4th celebrations. Now that I’m protein baking, it was only fitting to make a Protein Flag Cake!


Not only does it look great, but it’s delicious! It is a sweet vanilla protein cake topped with sweetened (with stevia) cashew cream and fresh berries. A delicious combination! (The photo above is 1/8 of the cake, which I realized was a bit large. I’m recommending this to be 12 servings, instead.)

And I’m using Warrior Blend vanilla protein powder, a pea protein blend that bakes up very well. For an easier cake, use our Vanilla Protein Cake Mix. The Value Size package would fit the 13×9 pan perfectly!

Perfect for summer or after a heavy meal, this Protein Flag Cake is a light protein treat. And it is bursting with berry flavor!


There aren’t many backyards here in Manhattan, but we have lots of rooftops with beautiful views! I have some friends who live in this building with a great view overlooking the East River. (Not only is the view great, but they are great friends!)

Enjoy your celebration, and stay safe!

Makes on 13x9" (33x23cm) cake, 12 servings.
  1. Preheat oven to 325F (163C).

  3. Mix or blend all cake ingredients until smooth.
  4. Pour batter into pan.
  5. Bake for about 20 minutes, until the cake is firm and a toothpick comes out clean.
  6. Let the cake cool to room temperature.
  7. Once cool, top the cake with cashew whipped cream.
  8. Make the flag design by first placing blueberries, then following with strawberry stripes.
  9. Slice, and enjoy!
  10. Store in the refrigerator.
A note about substitutions: because each type of protein powder has a distinct flavor and texture when baked, I would not try substituting different types of protein powders in this recipe (other than a pea blend like Warrior Blend).
Also, for those of you outside the states, feel free to message me for ideas of how to create your country's flag design!
And, almond meal can be made by pulsing almonds in a food processor. Sift out the large pieces and pulse again. Be careful not to overprocess, as this will give you almond butter.
