Keto Banana Cake with Peanut Butter Frosting Recipe [A Low-Carb Creamy Dessert]

Is anyone up for some creamy desserts for a change? Since I’m in the mood to bake today, I thought I would share my keto banana cake with peanut butter frosting recipe. And yes, we use actual bananas to make this cake and extract, but we make sure the carbs are low.

The cake is sugar-free and super moist, too, since each bite will simply melt in your mouth. Although you may think that peanut butter frosting is unhealthy and fattening, our homemade recipe will indeed prove you wrong.

Let’s get started and see what needs to be done to back our special low-carb banana cake with peanut butter frosting.

Dry Ingredients

1.Almond flour- Almond flour is an ingredient that is helpful when it comes to baking keto goods. A word of advice would be to use super fine blanched almond flour to make your batter perfect.

2. Coconut flour- Although coconut flour cannot be used as a substitute for almond flour because coconut flour is drying. But in order to get the perfect texture of the batter, we can combine them both so that our cake comes out nice and fluffy.

3. Baking powder- make sure the baking powder is gluten-free.

4. Salt- believe it or not, baked items need a pinch of salt to balance the flavor.

5. Cinnamon – using ground cinnamon is absolutely optional, but I always add a bit to my cakes to give them that unique flavor.

6. Xanthan gum- Xanthan gum needs to be used for this recipe to hold the better together; otherwise, your cake may fall apart when baking.

7. Sweetener- although you can add your preferred sweetener but I always use Swerve because of its taste which is almost close to regular sugar. And for the frosting, you will need Swerve in powder form.

Wet Ingredients

1.Eggs- must be at room temperature.

2. Unsalted butter- Unsalted butter is used to make the cake rich in texture and delicious to eat. Although you can use any type of oil for the batter, unsalted butter also helps to control the salt level.

3. Mashed banana- yes, we use a small amount of banana to get the actual flavor in the cake. Make sure the banana is overripe, as it will add to the sweetness.

4. Banana extract- since our cake is keto-friendly, we cannot use as many bananas as we want. Hence if you’re going to enrich the flavor, then incorporate gluten and sugar-free banana extract into the recipe.

5. Vanilla extract- those who are used to baking know that vanilla extract is a key ingredient that helps eliminate the smell of eggs in the batter.

6. Peanut butter – if possible, go for sugar-free creamy peanut butter.

7. Cream cheese- this ingredient is needed for peanut butter frosting.

Process Of Making Keto Banana Cake With Peanut Butter Frosting

1. First, preheat the oven to 350°F and then grease two cake pans which are 9 inches each.

2. Take a large bowl and mix all the dry ingredients with a whisk that includes almond flour, coconut flour, salt, ground cinnamon, baking powder, xanthan gum, and sweetener.

3. In a small mixing bowl, mash the ripe banana and set aside.

4. Now, take another large mixing bowl and combine the sweetener and unsalted butter together. Then add vanilla extract, banana extract (optional), and mashed banana. Mix all the ingredients together with a hand mixer until the batter is fluffy.

5. Add the eggs one by one inside the bowl and mix everything together.

6. Now, take the mixture of the dry ingredients and gently stir into the bowl of wet ingredients until everything is well combined together.

7. Divide the batter equally into the two greased pans and bake for about 25 minutes or until you see that the cake has become golden brown in color.

8. Let the cakes cool in the pans for a while, and then move them to a cooling rack so that they can completely cool before adding the frosting.

9. For the frosting, you need to mix the peanut butter, cream cheese, and unsalted butter together in a large bowl and mix with a hand mixer to get a smooth velvety texture.

10. Then add the sweetener, salt, and vanilla extract and mix everything together thoroughly. Make sure you use a rubber spatula to scrape off the ingredients from the side of the bowl.

11. If your cake has completely cooled down, you can add a thick layer of frosting in between two layers and on the top too. It’s up to you how you want to decorate the cake. Sometimes I sprinkle sugar-free dark chocolate chips on top to make it look more tempting.
