Why You’ll Love These Protein Bites

• Only 3 ingredients: No specialty items and no trip to a health food store.
• No added sugar: A ripe banana sweetens and binds the bites, so no honey or syrup is needed.
• High in protein: Peanut butter and protein powder give each bite about 12g of protein.
• No baking, no mess: Mix, roll and chill. That’s the whole process.

Ingredients (makes about 12 bites)

• 1 cup natural peanut butter (just peanuts and salt)
• 1 cup unsweetened vanilla or unflavored protein powder
• 1 very ripe banana, well mashed

How to Make No-Bake Peanut Butter Protein Bites

1. Mash the banana in a bowl until smooth, then stir in the peanut butter.
2. Add the protein powder and mix until a thick dough forms.
3. If the mixture is too sticky, add a little more protein powder; if it’s too dry, add a splash of milk.
4. Roll into 12 small balls using your hands.
5. Chill in the fridge for at least 20 minutes to firm up before serving.

Tips for Perfect Protein Bites

• Use a very ripe banana: Brown spots mean more natural sweetness and a smoother dough.
• Stir the peanut butter first: Natural peanut butter separates, so mix the oil back in before measuring.
• Know your powder: A cup of protein powder weighs roughly 100–120 g depending on the brand. Plant-based powders absorb more liquid, so you may need an extra splash of milk.
• Wet your hands: Slightly damp hands stop the dough from sticking while you roll.

Easy Variations

• Chocolate: Use unsweetened chocolate protein powder, or add 1 tbsp unsweetened cocoa powder.
• Crunchy: Roll the finished bites in chopped peanuts or unsweetened shredded coconut.
• Nut butter swap: Almond butter or cashew butter work the same way.

Storage and Freezing

• Fridge: Keep in an airtight container for up to 5 days.
• Freezer: Freeze in a single layer, then transfer to a freezer bag for up to 3 months. Let them sit for 5–10 minutes before eating.

Frequently Asked Questions

How long do these keep?
Up to 5 days in an airtight container in the fridge, or 3 months in the freezer.

Why unsweetened protein powder?
Many flavored protein powders contain sugar or sweeteners. Check the label for one without added sugar to keep these bites sugar-free.

Can I use a different nut butter?
Yes. Almond butter or cashew butter both work well.

What if I don’t have protein powder?
Substitute an equal amount of oat flour. The bites will still be filling, but the protein will be much lower.
