Add the cashew butter, maple syrup, and vanilla extract to a bowl and mix until combined.
Stir in the oat flour, protein powder, and salt. Mix the ingredients until a dough forms.
Scoop out the batter with a cookie scoop and use your palms to roll it into balls.
Pour the rainbow sprinkles onto a plate, then roll the cake batter protein balls in the sprinkles until they’re evenly coated.
Enjoy your cake batter protein balls immediately, or chill them in the fridge to firm up before serving.
Notes
Make sure to measure your ingredients carefully so the dough for your protein cake pops doesn’t turn out crumbly. You can add a bit of water to make the mixture more malleable.
You know what else could make these protein cake bites better? A white chocolate coating! Just dip the balls in melted white chocolate and finish with sprinkles.
To really capture that birthday cake flavor, make these birthday cake balls with almond extract!
