Birthday Cake Protein Bar Ingredients

Oat Flour: This fiber-rich flour gives these bars a distinct cake vibe.

Vanilla Protein Powder: Feel free to use your favorite. I usually use Tone It Up or Garden of Life.

Cashew Butter: You can use store bought, or check out all the deets on making your own here.

Maple Syrup: My favorite unrefined sweetener option.

Milk of Choice: Just a splash to get these birthday cake protein bars to the right consistency. I used unsweetened almond milk, but oat milk would be great too.

Refined Coconut Oil: The refined part is important here. We want the solidifying quality of coconut oil for these bars, but not so much the coconut flavor. Refined coconut oil has removed that taste.

Vanilla and Almond Extracts: Key for that birthday cake flavor.

Greek Yogurt: For the delicious (but healthy!) frosting.

Sprinkles: I mean, duh?

Sea Salt: Just a pinch to bring all the flavors together.

How to Store Birthday Cake Protein Bars

It is important to keep these bars chilled in order to keep them at the right consistency. However, you still have options depending on what vibe you’re going for.

  • Fridge: If you want your protein bars a bit softer, this is your best bet! They’ll still hold together thanks to that coconut oil, which solidifies when chilled.
  • Freezer: My personal favorite. The bars will be a bit more solid, but I love the ease of having them on hand for up to a month.
