This recipe was inspired by our popular keto banana bread, which is also gluten-free, sugar-free, and dairy-free.

Our banana keto cake is a little sweeter than our low carb banana bread recipe, plus it features vanilla icing.

This recipe can be customized by adding some chopped walnuts to the batter before baking for a slightly different flavor profile.

Are Bananas Keto?

If you’re wondering if you can eat bananas on a keto diet, the correct answer is no.

The reason is that just one medium banana has 27 grams of carbs and 3 grams of dietary fiber, for a total of 24 net carbs.

This is not even considering the fact that in traditional banana cake recipes, you use very ripe bananas or overripe bananas, which would further increase the amount of sweetness and carbs.

Bananas are too high in carbs and sugar in the form of fructose; therefore, they are too high in carbs.

Thankfully, this keto banana cake recipe delivers both flavor and texture, allowing your sweet tooth to be silenced.

Best Banana Extracts (Banana Flavoring)

You may be wondering how you can enjoy a banana recipe without using any mashed bananas.

Well, that’s where using a high-quality banana extract is the only way to gain flavor without the carbs.

It’s perfect for anyone on a low-carb diet.

Clocking in at only 2 grams of net carbs per serving, the carb count makes it the best choice for a keto banana cake.

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

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

OliveNation Pure Banana Extract works well in giving that rich, ripe banana taste without making it taste fake. 

Another great option is OOOFLAVORS banana nut bread extract.

If you go the route of OOOFLAVORS you’ll only use four drops, whereas OliveNation Pure Banana Extract requires a full teaspoon. Both work well in this recipe.

How To Make Keto Banana Cake In A Bundt Pan

Making this cake is pretty straightforward. You’ll begin by preheating your oven to 350 degrees and thoroughly greasing a 9.5-inch, 12-cup bundt pan with coconut oil.

Then, mix almond flour, coconut flour, salt, baking powder, psyllium powder, flax meal, and spices in a large mixing bowl to create your dry ingredients.

For the wet ingredients, melt the coconut oil, allow it to cool, and combine the cooled coconut oil with a sugar substitute, maple syrup, banana, and vanilla extract. Then, using an electric mixer, beat the eggs one at a time until they are well combined.

Slowly add the dry ingredients to the wet batter and beat at low-medium speed until well incorporated.

Then, add the almond or coconut milk and continue to mix. Pour the batter into the prepared bundt pan and bake in the oven for 40–50 minutes, or until it passes the toothpick test and comes out clean.

Allow the cake to cool for 5 minutes before removing it from the bundt pan and placing it on a wire rack to cool completely.

Once it has cooled, you can add the vanilla sugar-free icing, which combines the sugar-free powdered sweetener, dairy-free milk, vanilla extract, and salt in a small bowl.

Drizzle the icing over the top of the cake and serve.

The Flours

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.

I added psyllium husk powder, a secret ingredient that fiber,extra fiber to this low-carb cake recipe.

I also used a combination of golden flax meal, coconut flour, and almond flour, which are naturally high in fiber.

Fiber is 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 cake option.

Spices

When it came to getting the right flavor for this keto mock banana cake, I knew that in addition to an excellent banana extract, it also needed ground cinnamon and nutmeg.

I know that not everyone adds these warm spices to their banana bread, but I believe it enhances the flavor and makes it taste like the real thing.

The Sugar Substitute

It’s important to note that this recipe calls for a substitute for brown sugar. When I used to make my original recipe for banana cake, I always used brown sugar.

My two favorite brands are Swerve brown sugar and Surkin Gold.

I also added a couple of tablespoons of sugar-free maple syrup to mimic the flavor of brown sugar in this recipe further.

My favorites are Lakanto Maple Syrup and Choczero Honest Maple Syrup. They both work perfectly in this recipe.

How To Store Keto Banana Cake?

Once your keto banana cake has come out of the oven and has been allowed to cool thoroughly on a wire rack, you can wrap it in plastic wrap and store it in your refrigerator in an airtight container for up to five days. or freeze for up to three weeks.

Then, allow the cake to thaw overnight in the fridge or place it in a 300-degree oven for 20–25 minutes until it’s hot and defrosted.
