• Freezer-friendly and great for meal prep: Make them once and enjoy stress-free mornings for days.
• No fancy ingredients: Simple pantry staples like ripe bananas, oats, and eggs do the heavy lifting.

Shopping List

• 3 very ripe bananas (the spottier, the better)
• 2 large eggs
• 1 cup plain Greek yogurt (2% or whole)
• 1/3 cup maple syrup or honey
• 2 teaspoons vanilla extract
• 1 1/2 cups rolled oats (old-fashioned)
• 1 cup white whole wheat flour (or all-purpose)
• 1 scoop (about 30g) vanilla or unflavored whey protein powder
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon fine sea salt
• 1 teaspoon ground cinnamon
• 1/3 cup chopped walnuts (or pecans)
• 2 tablespoons melted coconut oil or neutral oil (optional for extra moisture)
• Optional mix-ins: 2 tablespoons ground flaxseed, 1/4 cup mini chocolate chips, or 2 tablespoons chia seeds

How to Make It

1. Prep your tools: Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with liners or lightly grease it.

   This helps release the muffins cleanly.

2. Mash the bananas: In a large bowl, mash bananas until mostly smooth. A few small lumps are fine and add texture.
3. Whisk in wet ingredients: Add eggs, Greek yogurt, maple syrup, vanilla, and melted oil (if using). Whisk until creamy and well combined.
4. Combine dry ingredients: In a separate bowl, stir together oats, flour, protein powder, baking soda, baking powder, salt, and cinnamon.

   Break up any protein powder clumps.

5. Bring it together: Add the dry mix to the wet ingredients. Stir gently just until combined. Avoid overmixing so the muffins stay tender.
6. Fold in the nuts: Add chopped walnuts (and any optional mix-ins) and fold lightly.

   The batter will be thick and scoopable.

7. Fill the cups: Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full. Top with a few extra walnut pieces for crunch if you like.
8. Bake: Bake for 18–22 minutes, or until the tops spring back and a toothpick comes out clean or with a few moist crumbs.
9. Cool: Let muffins rest in the pan for 5 minutes, then transfer to a wire rack to cool completely. This helps set their structure.
10. Serve: Enjoy warm as-is, or spread with a little peanut butter for more protein and healthy fats.

Storage Instructions

• Room temperature: Store in an airtight container for up to 2 days.
• Refrigerator: Keep in a sealed container for up to 5 days.

  Reheat in the microwave for 10–15 seconds to soften.

• Freezer: Freeze in a single layer, then transfer to a freezer bag. They keep well for up to 3 months. Thaw overnight in the fridge or microwave in short bursts.
• Meal prep tip: Wrap muffins individually for grab-and-go mornings.

Benefits of This Recipe

• Balanced macros: Protein powder, yogurt, eggs, and nuts create a solid protein profile.

  Oats and flour bring complex carbs for lasting energy.

• High in fiber: Oats, bananas, and nuts support digestion and help you stay full longer.
• Lower added sugar: Ripe bananas and a touch of maple syrup keep sweetness natural and controlled.
• Kid-friendly and lunchbox-ready: Sweet, soft, and portable with none of the mess of a loaf.
• Flexible for dietary needs: Easy swaps for gluten-free or dairy-free options without sacrificing texture.

Common Mistakes to Avoid

• Using underripe bananas: Green or barely yellow bananas won’t mash well and won’t deliver enough sweetness or moisture.
• Overmixing the batter: This can make the muffins tough. Stir just until the dry bits disappear.
• Overbaking: Protein bakes can dry out quickly. Start checking at 18 minutes and pull them when the tops spring back.
• Not measuring protein powder correctly: Different scoops vary.

  Aim for about 30 grams by weight for consistent results.

• Skipping the liners or greasing poorly: These muffins can stick. Use liners or grease well for easy release.

Alternatives

• Gluten-free: Use certified gluten-free oats and a 1:1 gluten-free flour blend. The texture stays soft and tender.
• Dairy-free: Swap Greek yogurt with a thick dairy-free yogurt (coconut or almond) and choose a plant-based protein powder.
• No protein powder: Replace the scoop with 1/4 cup additional flour and 1 tablespoon ground flaxseed.

  The muffins will still be hearty.

• Nut-free: Skip the walnuts and use seeds (pumpkin or sunflower) for a similar crunch.
• Flavor twists: Try chocolate protein powder + mini chips, or add blueberries and lemon zest for a fresh spin.
• Sweetener swaps: Use brown sugar instead of maple syrup for a deeper, bakery-style flavor.

FAQ

Can I use almond flour instead of regular flour?

Almond flour alone won’t give the same structure. If you need a grain-free version, use a tested almond flour muffin recipe as your base and adapt flavors. For this recipe, stick to all-purpose, white whole wheat, or a 1:1 gluten-free blend.

What type of protein powder works best?

Whey isolate or whey concentrate blends bake nicely and keep the muffins moist.

If using plant-based protein, you may need an extra tablespoon or two of liquid because plant powders absorb more moisture.

How can I make these sweeter without adding lots of sugar?

Use extra ripe bananas, add a few mini chocolate chips, or stir in a tablespoon of date syrup. You’ll get more sweetness without a big spike in added sugar.

Why did my muffins sink in the middle?

They may have been underbaked or the leavening was old. Check your baking powder and soda freshness, and bake until the centers spring back and pass the toothpick test.

Can I make them without eggs?

Yes.

Use two flax eggs (2 tablespoons ground flaxseed + 5 tablespoons water, rested 10 minutes). The texture will be slightly denser but still delicious.

Do I need the oil?

No, but a little fat improves tenderness and keeps the muffins moist after refrigeration. If skipping oil, be careful not to overbake.
