Overview of Ingredients

Almond Flour

Almond flour is a fantastic gluten-free alternative to regular flour, offering a nutty flavor and higher protein content. If you don’t have almond flour, finely ground oat flour or coconut flour may work, but keep in mind coconut flour is more absorbent and may require adjusting liquids.

Ripe Bananas

Bananas are the star of this recipe, providing natural sweetness and moisture. Use bananas that are very ripe with lots of brown spots for the best results and texture. Overripe bananas enhance the muffin’s sweetness without needing added sugar.

Coconut Oil

Coconut oil replaces butter or vegetable oil to give the muffins a subtle tropical note and keeps them tender. If you’re not a fan of coconut oil, you can substitute with melted butter or a neutral oil like avocado oil.

Protein Powder

Adding protein powder boosts the muffin’s nutritional value and helps create a satisfying snack or breakfast option. Choose a clean, unflavored protein like grass-fed whey protein powder to keep the banana flavor front and center.

Eggs

Eggs act as binders and contribute to the structure of the muffins. 

Tips for Success

#1 Use overripe bananas

The sweeter and softer your bananas are, the better your muffins will turn out. Don’t be shy to let those bananas get really spotted—your muffins will thank you for it.

#2 Measure almond flour properly

Almond flour can get dense if packed too tightly. Use a spoon to gently scoop it into your measuring cup rather than scooping directly so your muffins stay light and fluffy.

#3 Don’t overmix the batter

Mix just until ingredients are combined to avoid dense muffins. Overmixing develops the almond flour’s texture too much, which can make the muffins tough.

#4 Let the batter rest briefly

Allow the batter to sit for 5 to 10 minutes before baking. This gives the almond flour and protein powder a chance to absorb moisture, improving the muffin’s texture.

#5 Use paper liners or grease the pan well

These muffins can be a bit delicate due to almond flour, so liners or thorough greasing help them slip out easily without crumbling.

Equipment:

Muffin Tin
Mixing Bowl
Measuring Cups and Spoons

​How to Make the Best High Protein Banana Muffins

Ingredients

• 2 cups blanched almond flour (252 grams)
• ⅔ cup unflavored protein powder (60 grams)
• 3 tablespoons coconut sugar
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ¼ teaspoon salt
• 1 ¼ cups mashed bananas, about 3 (288 grams)
• 3 eggs
• ⅓ cup melted coconut oil
• 2 teaspoons vanilla

Directions

• Preheat the oven to 400 degrees F. and line a muffin pan with liners. 

• In a medium bowl, combine the almond flour, protein, coconut sugar, baking soda, baking powder, and salt.

• In a separate bowl, whisk together the wet ingredients – bananas, eggs, coconut oil, and vanilla.

• Pour into the dry ingredients and fold in just until combined. Do not overmix.

• Divide the batter into 12 liners and bake for 5 minutes. Reduce the heat to 375 degrees F. and bake for 18-22 minutes, until they start turning golden brown and a toothpick inserted in the middle comes out clean.

Recipe Variations

Add Nuts or Seeds:
Stir in chopped walnuts, pecans, or chia seeds for a crunchy boost and extra nutrients.

Chocolate Chips:
For a touch of indulgence, mix in some semi-sweet or dark chocolate chips before baking.

Spiced Banana Muffins:
Add a teaspoon of cinnamon or pumpkin pie spice to complement the banana’s natural sweetness.

Dairy-Free and Nut-Free:
Use oat flour instead of almond flour and substitute coconut oil with avocado oil to accommodate allergies.

Troubleshooting Common Problems with this Recipe

Muffins Are Too Dense
Check that you aren’t overmixing the batter, and use ripe bananas for moisture and sweetness. Also, sift the protein powder if it’s clumpy to avoid uneven texture.

Muffins Don’t Rise Well
Make sure your baking powder or baking soda is fresh, as expired leavening agents won’t provide enough lift. Also, measure your almond flour accurately to keep the balance right.

Muffins Are Too Dry
Try adding a little extra banana or reduce baking time slightly. Coconut oil keeps moisture in, so make sure you’re not substituting it with something much leaner.

Crumbly Muffins
Grease your muffin tin well or use liners to maintain muffin shape when removing them. Don’t skip resting the batter before baking to help ingredients meld better.

Banana Flavor Is Too Mild
Use very ripe bananas and consider adding a teaspoon of vanilla extract to enhance the fruity notes.

Freezing & Storing Leftovers

Freezing:
Let muffins cool completely before freezing to avoid sogginess. Wrap each muffin individually in plastic wrap or place them in a freezer bag and freeze for up to 2 months. When you’re ready to enjoy, thaw them at room temperature or warm them gently in the microwave.

Storing:
Store leftover muffins in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate for up to a week, but be aware refrigeration might slightly change texture.

How To Reheat

Oven Method
Best for: Keeping muffins moist yet slightly crisp on the outside. Preheat your oven to 325°F (160°C). Place muffins on a baking sheet and warm for about 10 minutes. This will revive their texture without drying them out.

Microwave Method
Best for: A super quick fix when you want muffins ready in moments. Place a muffin on a microwave-safe plate and heat for 20-30 seconds. Use a damp paper towel to keep moisture locked in, but note this method softens the muffin’s outer edges.

Toaster Oven Method
Best for: Toasting muffins just slightly to add a bit of crunch. Heat muffins at 325°F for 5 to 7 minutes. This brings out the nutty aroma and fresh-baked feel.

Extra FAQs

Can I use a different type of protein powder?
Absolutely. Just keep in mind some protein powders absorb moisture differently. If using plant-based powders, you might want to add a splash of extra liquid to keep muffins tender.

Are these muffins suitable for people with gluten intolerance?
Yes, the recipe uses almond flour, which is naturally gluten-free. Just double-check that your protein powder and other ingredients are also labeled gluten-free.

Can I make these muffins nut-free?
You can substitute almond flour with oat or sunflower seed flour, but this might slightly alter the texture and flavor. Use a nut-free protein powder to be safe.

How long do these muffins stay fresh?
At room temperature, they stay fresh for about 3 days, and refrigeration extends this to around a week. Freezing helps preserve them for a couple of months.

Can I double the recipe and bake in a larger pan?
Doubling the recipe works fine, but you’ll want to adjust baking times and use an extra muffin tin. Keep an eye on them to avoid overbaking.
