Keto Banana Nut Bread

Keto Banana Nut Bread, it has all the flavor of traditional banana bread minus the high carbs. How is that possible? Well, it’s because this is keto-friendly mock banana bread and it does not use bananas in the batter. If you’re wondering if you can eat bananas on keto, the correct answer is no.

Why not? Well, because bananas are high in fructose and therefore too high in carbs. But don’t let that steer you away. Since this mock banana bread really delivers on both flavor and texture.

One bite of this moist keto banana bread and you’ll have a hard time believing there are zero bananas in it. So there is no need to worry if this sugarless banana nut bread fits your macros because it does. 

Although this recipe for keto banana bread does not use any bananas, you know what? It still tastes like it has ripe bananas. I’ll admit I wasn’t sure I could create a mock banana bread that could fool my taste buds. 

You see after I went keto I thought I would never again enjoy a slice of banana bread. Which was kinda sad considering it was a staple in our home. But here’s the thing, I learned years ago that the secret to moist delicious banana bread is the use of really ripe bananas. 

Do you know what happens when a banana ripens to the point that the peel turns black? It becomes sweeter. Ugh, no doubt it’s probably why this girl LOVED banana bread.  But clearly, a super ripe banana means that it’s also super high in carbs and a definite no on keto.

You should know, that for a good while now my daughter Michelle kept asking for a keto version of my banana bread. “Mom, can’t you just add one banana to the batter?” “I mean how bad can one banana be?”  And each time I would tell her no Michelle just no. 

But why was I so sure it wouldn’t be a good idea? Well because I had zero confidence that a green banana would any real banana flavor. So why bother adding more carbs if it made no difference?

Look I know there are some recipes out there that add some banana to the batter and still call it keto, but I just couldn’t see myself doing this. Some of us really can’t afford the extra carbs.

So I had to find a more keto-friendly way to enjoy all the flavor but leave out the high amount of sweetness a ripe banana adds.  Adding one green banana to the batter was not an option for this girl. Remember when I used to make banana bread I would let my bananas ripen to the point that they were mush.

Keto-friendly Mock Banana Bread

If I was after that type of flavor a green banana would not cut it. But what if I could get the texture of the bread right and use a high-quality banana extract? Hmmmm now this I at least had to try.

I knew I could get the right mouth-feel for a keto banana bread by using some golden flax meal and psyllium fiber along with coconut and almond flour.  All that would be left was finding the perfect substitute for banana flavor.

Right about you now you may be wondering Hilda, how on earth can you call this a banana bread recipe and not use any bananas? Well, that’s where using a high-quality banana extract is the only way to gain flavor without the carbs.  

A high-quality banana extract is indeed keto-friendly and can fit into your macros easily. And since a little goes a long way, it’s a great option for anyone doing a keto diet that is missing the flavor of ripe bananas.

Not all banana extracts are the same so choose wisely. You want an extract that gives a ripe banana flavor. This of course is my personal preference.

 OliveNation Pure Banana Extract works really well in giving that rich banana taste without it tasting fake. Your tastebuds will think you’ve cheated but they would be wrong.

Another great option is OOOFLAVORS,they really delivered with their banana nut bread extract. I knew it would work because their extract does not taste like the fake banana flavor you find in say candies. No, their extract really tastes like ripe bananas.

These people obviously understood that the banana flavor had to be one to mimic ripe bananas if it had a chance to fool our tastebuds.  

It really delivers the flavor of ripe bananas perfectly. It’s hard to believe that six little drops would deliver so much flavor but it does. It’s actually a flavor concentrate so this explains the bold flavor of ripe bananas. And because it also includes a walnut extract in the mix it works really well in our keto banana nut recipe. 

How To Make Keto Banana Bread

You should know it’s not the first time I make a mock recipe. I have a keto “corn” bread that tastes like it uses cornmeal.

In fact, I even have a keto cornbread that uses coconut flour.   What’s more, I even have a few mock apple recipes like my keto “apple” pie and my keto “apple” cobbler that uses chayote squash instead of real apples.  Just like those recipes, this low carb banana bread recipe is a winner in our book. Plus all the ingredients are easy to come by.

Making this delicious mock banana bread grain-free, gluten-free, sugar-free, dairy-free and keto-friendly.  Can I just say that I became a believer in the flavor of ripe bananas when the queen of banana bread in our family, Miriam shared her secret of using only bananas that are completely black?

Miriam’s banana bread is a thing of legends in our family it’s the one recipe she knows she will always get requests for. But alas for us, this side of the family needed an alternative if we were ever going to enjoy banana bread again. 

But it’s her recipe that had me on the quest for the right texture and flavor for this keto mock banana nut bread. So although, it’s not exactly like her bread, missing her bread is what inspired us to give it a try. 

The Flours

To get the perfect texture for this keto banana nut bread I used a combination of flours. This recipe uses almond flour, coconut flour, golden flax meal, and psyllium powder.  An added plus about this recipe is that the use of all these flours also makes a keto high fiber bread.

I’m a big fan of sneaking more fiber into my recipes. Frankly, I feel that most people doing keto are not getting enough fiber in their diet. Fiber is something that’s essential for our good gut bacteria to flourish. So trust me when I tell you it’s a good thing that this is a high fiber keto banana bread option.

When it came to getting the right flavor for this keto mock banana bread I knew that in addition to a great banana extract that it also needed both ground cinnamon and nutmeg.

I know that not everyone adds these warm spices to their banana bread but I disagree because it really enhances the flavor. Of course, do make sure that your spices are fresh. This is important since stale spices have zero value and can even affect the overall flavor. I make it a point to replace my spices every season to ensure quality. 

The Sugar Substitute

It’s important to note that this recipe uses a substitute for brown sugar. Back when I used to make traditional banana bread I always used brown sugar. It’s what I learned from Miriam the banana bread expert. 

So I knew that using a brown sugar substitute was a must. My two favorite choices are Surkin Gold and Lakanto Gold. Either one works well. I also added a couple of tablespoons of sugar-free maple syrup to further mimic the texture of brown sugar in this recipe.

My favorite is Lakanto Maple Syrup and Choczero Honest Maple Syrup. They both work perfectly in this recipe.
