FAQs

Can I use any type of protein powder?

Yes, both plant-based and whey protein powders work. Choose chocolate or vanilla flavors for best results.

Are these suitable for kids?

Absolutely. They’re naturally sweetened and free from refined sugars, making them a great snack for children.

Can I omit the cocoa powder?

You can, but the cocoa contributes to the rich brownie flavor. For a non-chocolate version, try using vanilla protein and add cinnamon or nutmeg instead.

Do I need silicone baking cups?

Silicone cups work best for easy release, but paper liners can be used if lightly greased.

Can I use unripe bananas?

Very ripe bananas are essential for sweetness and moisture. Unripe bananas won’t provide the same flavor or texture.

How do I know when they’re done?

They should be just set on top but still soft. They’ll firm up as they cool, so avoid overbaking.

Are these freezer-friendly?

Yes. These bites freeze well and are perfect for meal prep or batch baking.

Is almond butter better than peanut butter?

Both work equally well. Almond butter offers a slightly milder taste, while peanut butter gives a more classic flavor.

Can I add oats to the recipe?

Yes, adding 1–2 tablespoons of quick oats can add texture, though it will slightly alter the consistency.

How can I increase the sweetness?

If your bananas aren’t sweet enough, add 1–2 teaspoons of maple syrup or honey (if not vegan).

Flourless Protein Brownie Bites are proof that nutritious snacks don’t have to sacrifice flavor.
