Banana bread is a staple recipe for good reason, but some recipes can overcomplicate things for no real benefit. Not to mention that anyone who is on a gluten-free diet can’t enjoy the traditional version!

This banana bread was created with simplicity and nourishment in mind, because most of the time, less is truly more. Four ingredients are all you need to make a delicious, higher-protein, gluten-free version of your favourite sweet treat.

This recipe requires only ripe bananas, protein powder, eggs, and almond flour. But it’s more than enough to create a moist, tender, and sweet bread that is naturally gluten-free and leaves you feeling fueled and satisfied.

Make this 4-ingredient banana bread ahead of time for a quick breakfast, a filling snack, or a healthy dessert.

Why you’ll love this banana bread

Four staple ingredients required. You’ve likely already got these ingredients sitting in your pantry.

Higher in protein than traditional banana bread. This means every slice is delicious AND fuels your body.

Naturally gluten-free. This recipe uses almond flour to make it gluten-free.

Perfect for making ahead of time. This banana bread holds up well in the fridge or freezer, so prep it for a busy week or month ahead!

Easily customizable. This recipe is the perfect base for any add-ins you might like. A dash of cinnamon, chocolate chips, toasted nuts, or shredded coconut all make for great additions.

Ingredients you’ll need

Very ripe/overripe bananas. Since bananas are the star of the show, be sure to choose bananas that are either fully brown or at least spotty. The riper they are, the sweeter and more flavourful your 4-ingredient banana bread will be!

Protein powder. This gives the banana bread a great protein boost. I’d suggest a good quality protein powder with a simple flavour like vanilla, caramel, or chocolate, but feel free to experiment. Unflavoured protein powder works too, just keep in mind that the banana bread will lose some sweetness and flavour.

Almond flour. This adds a nutty flavour and tender texture to the bread, while keeping it gluten-free.

Eggs. These are needed to hold the banana bread together and add moisture.

Health benefits

Promotes stable energy levels. Thanks to the added protein, healthy fats, and reduced amount of sugar, having a slice will bring a significantly smaller spike in blood sugar compared to a traditional banana bread.

Keeps you satiated for longer. The ingredients in this bread have plenty of fats and protein to actually keep you full, making it the ideal quick snack or on-the-go breakfast.

Provides plenty of essential vitamins and minerals. All four ingredients contain essential nutrients, such as vitamin E, vitamin B, and potassium.

Great for digestion. Both almond flour and bananas contain fibre, which is key in supporting your digestive system and a healthy gut.

Tips for success

Use ripe or overripe bananas. This will give the banana bread the most sweetness and flavour.

Don’t overbake! Keep a close eye on the bread from the 25-minute mark. Trust me, nobody likes a dry banana bread.

Let the bread cool completely before slicing. Allowing the banana bread to cool down ensures that it sets fully and makes slicing much easier.

Choose a nicely flavoured protein powder. Since this recipe is only 4 ingredients, the flavour of your protein powder will make all the difference.

Mix in ideas

This 4-ingredient banana bread is delicious as is, but you can easily elevate the flavour with a few simple add-ins before baking, such as:

chocolate chips
spices like cinnamon, nutmeg, allspice, or ginger
vanilla extract
toasted nuts
dried dates or raisins
shredded coconut
blueberries
