There’s something about banana bread that brings people together. Maybe it’s the smell while it bakes or that first warm slice with butter melting into it. But if you’re doing keto, bananas and bread both sound like a bad joke, right? Hang on, don’t write it off just yet.
We’re not using regular bananas here. And we’re definitely not using flour that sends your carb count through the roof. This keto walnut banana bread hits that sweet spot. It’s soft, not dry. Just enough sweetness, not overly rich. And those walnuts? Game changer.
This recipe’s got your back if you’re trying to eat low-carb without giving up on food that actually tastes like food.
So, What’s The Walnut Banana Bread Trick Here?
Bananas are full of sugar. Like, a lot. So we’re not using whole bananas in this bread. We cheat a bit with banana extract—same smell, same taste, way fewer carbs.
Also, instead of all-purpose flour, we go with almond flour. Coconut flour would work too, but it’s a little more picky. Almond flour keeps things soft and moist. And yes, it’s gluten-free if that’s something you’re watching.
Sweetener? You can go with erythritol, monk fruit, or whatever low-carb sweet stuff you’ve already got in your pantry.
Let’s keep it simple.
Ingredients You’ll Need
Dry stuff:
- 2 cups almond flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- Pinch of salt
- 1 tsp ground cinnamon (optional but recommended)
- 1/2 cup chopped walnuts (plus extra for the top)
Wet stuff:
- 3 large eggs
- 1/3 cup melted butter (or coconut oil if you’re dairy-free)
- 1/2 cup erythritol or other keto-friendly sweetener
- 2 tsp banana extract (don’t skip this—it’s the hero here)
- 1 tsp vanilla extract
- 1/4 cup unsweetened almond milk
Step-by-Step Instructions to Making Keto Walnut Banana Bread
- Heat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper if you hate scrubbing dishes.
- Mix dry ingredients in one bowl—almond flour, baking powder, baking soda, salt, cinnamon, and chopped walnuts. Stir with a fork. No fancy tools needed.
- Beat eggs in another bowl. Add melted butter, sweetener, banana extract, vanilla extract, and almond milk. Mix until it looks like one smooth batter.
- Pour the wet stuff into the dry stuff. Stir until just combined. Don’t overmix. You want it just blended.
- Pour batter into your loaf pan. Sprinkle a few chopped walnuts on top for that extra crunch.
- Bake for 40–50 minutes. Start checking around the 40-minute mark. Stick a toothpick in the middle—if it comes out clean or with just a few crumbs, it’s done.
- Let it cool. Really. Don’t cut into it hot. Give it at least 20–30 minutes or it might crumble on you.
Why This Works for Keto
Let’s break it down quick:
- Almond flour replaces the usual white flour, which saves you from spiking your blood sugar. Plus, it’s full of healthy fat and protein.
- No bananas. Banana extract gives you the flavor, but you skip the sugar bomb.
- Keto sweeteners keep things sweet without the carbs.
- Eggs and butter help with texture and hold everything together without needing gluten.
Taste and Texture
You know how some keto baked goods taste like flavored foam? This doesn’t. It actually holds together. You get that classic banana bread softness in the middle, with a golden crust on the outside. The walnuts add crunch and a little richness.
The banana extract really does carry the flavor here. If you’ve ever had artificial banana flavor and hated it—don’t worry. A good banana extract doesn’t taste like bubblegum. It’s mild, warm, and when baked, smells just like the real thing.
What to Serve It With
- With coffee in the morning, because let’s be honest, some days, you just want cake for breakfast.
- With a spread of butter or almond butter for extra fat and flavor.
- With whipped cream or cream cheese frosting if you’re feeling fancy (or having company).
You can also slice it up and freeze it. It keeps well. Just wrap slices in plastic wrap, then toss them in a freezer bag. Toast or microwave when you need a snack.
Common Mistakes and How to Avoid Them When Making Walnut Banana Bread
- Too dry?
Probably baked it too long or used too much coconut flour if you subbed that in. Stick to almond flour unless you’re confident in adjusting moisture levels. - Tastes eggy?
Try adding a splash of lemon juice or a bit more vanilla to tone that down. - Collapses after baking?
That’s usually from underbaking or overmixing. Use a toothpick to check it’s done.
Now Hear this Bread Baking Story
My brother’s been on keto for a year now. He’s not a baker, barely knows how to fry an egg. But after one try, he nailed this banana bread. He says it’s his go-to snack when cravings hit, and he even brings it to work. His coworkers, most of them not keto, ask for a slice. That’s when you know it’s not just “good for keto,” it’s just good.
Can You Make It Without Eggs?
Yes, but expect some changes in texture. Try using flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg). It’ll be a bit denser, not as fluffy, but still tasty. Might need a few tweaks based on your oven too.
Swaps and Add-Ons
Want to switch it up a little? Here are some easy changes:
- Add sugar-free chocolate chips for a bit more sweetness.
- Use pecans instead of walnuts if that’s what you’ve got.
- Throw in shredded coconut for texture.
- Add a swirl of peanut butter before baking if you’re in the mood for something wild.
How Long Will It Last?
On the counter, covered: about 2–3 days.
In the fridge: up to a week.
In the freezer: up to 2 months.
Just make sure it’s cooled completely before storing. Warm bread in plastic gets soggy, and no one wants that.

Frequently Asked Questions (FAQs)
Can I eat walnut banana bread on a keto diet?
Traditional walnut banana bread is too high in carbs for a keto diet because it uses flour and ripe bananas. But with this keto banana bread recipe, you skip the bananas and use banana extract instead, so you still get the flavor without the sugar and carbs.
What can I use instead of banana in my keto banana bread?
Banana extract is the best substitute if you want the flavor without the carbs. It keeps the bread low-carb while still tasting like real banana bread. Some people also add mashed pumpkin or zucchini for texture, but banana extract keeps it simple.
Is almond flour good for baking bread?
Yes, almond flour is one of the best flours for keto baking. It’s low in carbs, gluten-free, and gives bread a soft, moist texture. It works perfectly in this keto walnut banana bread to keep it fluffy without using wheat flour.
