Frequently Asked Questions

Can I use creamy or crunchy peanut butter?
Yes! Both work well in this recipe. Creamy peanut butter creates a smooth, peanut butter cup-like center, while crunchy peanut butter adds extra texture and bits of peanuts throughout each bite. For best results, use a natural peanut butter made with just peanuts and salt.

What type of protein powder works best?
Vanilla protein powder adds a subtle sweetness and flavor, but unflavored protein powder can also be used.

Can I make these dairy-free?
Absolutely. Simply use dairy-free chocolate chips and your favorite plant-based protein powder if needed.

Can I use a different nut butter?
Yes. Almond butter or cashew butter can be substituted, though the flavor and texture will vary slightly. Be sure to use a natural nut butter for the best consistency.

Can I make them nut-free?
You can experiment with sunflower seed butter for a nut-free option. The flavor will be a little different, but it should still work well in the recipe.

Why is my mixture too soft or too dry?
Natural peanut butters and protein powders can vary quite a bit. If the mixture feels too soft, chill it for 15–20 minutes before shaping. If it feels too dry, add a teaspoon of milk at a time until the mixture comes together.

My favorite protein powder

For the best flavor and texture, I love using FlavCity Vanilla Protein Powder in these peanut butter protein bites. It has a delicious vanilla flavor that complements the peanut butter perfectly, and it’s made with simple, high quality ingredients, including grass-fed whey protein.

If you’re looking for a clean protein powder that tastes great in both snacks and smoothies, this is one I highly recommend.
