Craving dessert but still need to get your protein in? These cake batter protein balls are made with easy ingredients and rolled in sprinkles for an irresistible snack that tastes incredible!

My original energy balls are one of my top recipes for a reason: they are absolutely delicious. Once I mastered how to make protein balls taste like dessert (some readers say they taste like cookie dough), the possibilities were endless.

Since then I have made many variations of protein balls, and these sprinkle covered cashew ones are my newest creation!

They are made with the classic protein ball ingredients: oats, protein powder, and nut butter, and rolled in sprinkles for a fun and colorful treat.

How to make Birthday Cake Protein Balls

Step 1: Add the cashew butter, vanilla protein powder, rolled oats, vanilla extract, honey, salt, and sprinkles to a mixing bowl.

A note about the cashew butter: I used unsalted cashew butter for this recipe. If yours contains salt, omit the added salt in this recipe until after you mix it together. Then you can salt to taste, if needed.

Step 2: Use a rubber spatula to mix all of the ingredients together until it looks like cookie dough batter. There should be no streaks and the consistency will be slightly sticky.

Step 3: Use a mini cookie scoop to drop balls of batter onto a parchment paper lined baking sheet. You should get around 15 protein balls.

Step 4: Roll each ball with your hands, then dip the top into a small bowl of sprinkles. Place the ball onto the baking sheet sprinkle side up, then repeat until you are finished.

How to store protein balls

In the refrigerator: Store leftover birthday cake energy balls in an airtight container in the refrigerator for 1-2 weeks.

In the freezer: Store in an airtight bag or container for 2-3 months. The texture will be firmer when frozen, so make sure to allow the protein balls to thaw for several minutes for the best consistency before eating.

Protein Balls FAQs

Can I use a different flavor of protein powder?

You can, but I do not recommend it. Vanilla flavored protein powder will work best to achieve the cake flavor that we are going for.

What if I can’t find unsalted cashew butter?

If you use regular cashew butter, just leave out the additional salt. You can mix it all together and do a taste test to see if you need to add any more salt.

Where do I buy dye free sprinkles?

I have had luck finding sprinkles without artificial dye at Walmart, Kroger, and Amazon.
