What's the difference between cake and gluten-free cake? 


While many of the ingredients stay the same, the biggest difference between cake and gluten-free cake comes down to the flour. Regular cakes are made with all-purpose flour or cake flour. In gluten-free baking, specialized gluten-free flour blends are often utilized. 


These blends may contain rice flour, cassava flour, other gluten-free flour, or a mix. They sometimes utilize a thickening agent such as agar agar or xanthan gum to help with consistency. 


In addition to pre-made blends, you can also utilize almond flour and coconut flour, which are also naturally gluten-free. For this recipe, almond flour is used because its nuttiness is a complement to the banana flavor in the cake.


Why You’ll Love it 


Flavorful- If you like banana bread, you're going to love this banana cake. A light and sweet cream cheese frosting tops this almond flour cake for the perfect balance of taste and textures. The natural sweetness in the bananas goes so well with the nuttiness of the almond flour and granola. These are enhanced by the aromatic cinnamon for a well-balanced dessert. 


Easy- One of the best things about almond flour is that you can't overmix it. When all-purpose flour is overmixed, it can become dense and dry. Since almond flour is just finely ground nuts, you won't have to worry about overmixing- it's fool proof! Not to mention, you only need one bowl to mix in the cake and one for the frosting. 


Crowd pleaser- This cake tastes amazing and can be enjoyed by a range of people at gatherings. Whether the guests eat standard diets, eat reduced sugar or are sensitive to gluten, this banana cake is perfect for everyone to indulge in without sacrificing flavor or texture. 





NuTrail Granola- Our Cinnamon Pecan Granola adds a big crunch to this cake where walnuts might typically be used. The mixture of sunflower and pumpkin seeds, coconut, almonds and pecans, add even more flavor to the banana cake than a single type of nut would.  


BananasBananas provide natural sweetness and moisture to this gluten-free banana cake recipe. Look for those with dark peels but avoid overly ripe bananas that show signs of rotting.  


Eggs-These act as a binder and provide structure to the cake by helping it rise and hold its shape. 


Almond flour- The base of this gluten-free cake. Almond flour gives it a nutty, moist texture. Blanched finely ground almond flour is ideal for this recipe. Almond meal, however, will yield a much denser cake that tastes more like almonds and may not rise as well, but could still be used. 


Gluten-Free Baking powder and baking soda- These act as a leavening agent and help the cake rise and become fluffy. 


Cinnamon- Adds warmth and a delightful aroma that enhances the banana taste. 


Salt- Balances and enhances sweetness from the banana, granola, and low carb sweetener. 


Vanilla extract-  Vanilla lifts up the flavors in this simple cake. 


Sour cream- This adds a bit of acidity to the cake, which helps the cake rise through interaction with the leavening agents but also adds a more lively taste to the cake. You can use sour cream or plain Greek yogurt interchangeably. 


Sweetener- Low carb sweetener makes the cake sweet. Erythritol was used in making this cake but feel free to use your personal favorite type of granulated sugar alternative.  


Cream cheese- Softened cream cheese is used in the frosting, it adds creaminess and tanginess to balance the sweetness of the cake and create a velvety topping.


Tips and Substitutions  


- When choosing bananas for this recipe, you'll want to look for very ripe bananas. These have dark spots on the peel and are very soft. They have a more pronounced taste and mash easily, making them ideal for baking. If the bananas have many dark spots inside the peel or are completely black, those are typically too ripe and may have spoiled. 


- Swap the granola for one of our other delicious flavors such as Blueberry Cinnamon, Cacao Nut Granola, or even Birthday Cake! 


- Don't skimp on the leavening agents. Almond flour is much heavier than all-purpose flour and requires more leavening agents to get the desired lift. 


- Allow the cake to cool completely before removing it from the pan. Almond flour is notorious for crumbling when still warm, but once it cools, you will be able to lift it out effortlessly. 


- If you don't wish to use cream cheese frosting, you can also make a batch of homemade whipped cream for a light and airy alternative. Simply whip 1 1/2 cups of heavy cream and 1/4 cup of powdered sugar alternative sweetener in a large bowl until fluffy, then spread on top of the cake.

Not baking it enough can also cause this common problem. Some ovens have variable temperatures and may require an extra few minutes to cook. This is why it's very important to rely on visual doneness cues as well.
