How to Make Banana Peanut Butter Swirl Marshmallow Protein Bars

1. Line an 8×8-inch baking pan or loaf pan with parchment paper.
2. Add the milk and gelatin to a saucepan and allow the gelatin to bloom according to the package directions.
3. Heat over low heat, stirring constantly, until the gelatin is completely dissolved. Do not allow the mixture to boil.
4. Remove from the heat and pour the mixture into a food processor or high-speed blender.
5. Add the banana protein powder and blend for several minutes until the mixture becomes thick, fluffy, and nearly triples in volume.
6. Mix the peanut powder with the water until smooth.
7. Transfer the marshmallow mixture to the prepared pan. Drizzle the peanut butter mixture over the top and use a knife or skewer to gently swirl it throughout.
8. Refrigerate for at least 6 hours, although overnight is recommended for the best texture.
9. Slice into 8 bars and enjoy.

Tips for the Best Marshmallow Protein Bars

• Allow the gelatin to bloom completely before heating. This helps ensure a smooth mixture and a perfect set.
• Blend the mixture longer than you think you need to. The extra blending time is what creates the light, fluffy marshmallow texture.
• For clean slices, refrigerate the bars overnight before cutting.

Storage Tips

Store the bars in an airtight container in the refrigerator for up to one week.

Frequently Asked Questions

Can I use a different protein powder?

Yes, although the texture and flavor may vary. This recipe was developed specifically using Equip Foods Banana Prime Protein for the best results.

Can I use regular peanut butter?

You can, but powdered peanut butter creates a lighter swirl without adding excess oil or altering the bars’ texture.
