These Protein Banana Nut Muffins are soft, fluffy, perfectly sweet, and full of cozy flavor. Think your favorite coffee shop banana nut muffin, but make it high-protein.

Why These Stay So Moist
Protein baking can be tricky, but this recipe is designed to give you that soft, fluffy texture every time.
Here’s what makes the difference:
- Very ripe bananas → natural sweetness + moisture
- Greek yogurt → adds protein while keeping everything soft
- Brown sugar → helps retain moisture
- Balanced protein-to-flour ratio → no dryness or chalky texture
Moisture Tips (Very Important)
- Use VERY ripe bananas (brown spots = best)
- Do not overbake!! (Mine bake from 19/20 minutes)
- They’re even softer the next day
- If using plant protein, you may need to add 1–2 tablespoons of milk (although I used Truvani Vanilla plant protein and they turned out great with no milk!)
Protein powders absorb moisture differently, so small adjustments are totally normal.
My Go-To Baking Staples
To get the best texture and flavor, these are my must-haves:
- High-quality protein powder
- Tulip Muffin pan liners
- My favorite Mixing bowls
- Cookie scooper
- Organic vanilla extract
