What Is Gluten Free Banana Cake?

Banana Cake is a cake prepared using ripe bananas as a primary ingredient and typical cake ingredients like sugar, eggs and flour.

Banana Cake can be prepared in various ways, such as a banana layer cake, muffins or cupcakes. Steamed banana cake is also found in Chinese, Indonesian and Vietnamese cuisine.

Gluten Free Banana Cake, also known as GF Banana Cake, takes the traditional recipe concept and substitutes whole wheat flour for gluten free alternatives.

Gluten free baking is a staple for the celiac community as well as the growing number of people who have adopted gluten free diets.

Our moist Gluten Free Banana Cake recipe substitutes whole wheat flour for a mixture of oat flour, almond flour and cornstarch.

My Family Loves Gluten Free Banana Cake

My family loves baking.

We’ve mastered the art of sourdough bread, pretty pancakes, crunchy cookies and homemade pies.

When I was little my mom would dedicate hours to decorating specialty cakes for our birthdays. She’d visit the local bake shop to purchase cake pans in the shape of our favourite heroes of the moment, from My Little Pony to Cookie Monster.

She’d decorate our birthday cakes each year using specialty piping bags. Famously one year when I was a toddler, she was piping bright red fur onto a chocolate cake shaped like Elmo. Halfway through icing the cake she went to answer the phone and when she returned the icing had moved from the cakes surface to a joyous smear across my giggling face.

My love for eating cake into adulthood has been an honest and enthusiastic evolution. I’ve become a big fan of casual snacking cakes. They’re quick and easy to prepare since they don’t involve several layers and fillings or challenging icing designs.

My family love desserts that feature ripe bananas. Here are some of our favourites:

Types of Gluten Free Flour

If it’s your first time gluten free baking you may not be familiar with the variety of flours you can use when baking muffins, cookies and squares.

Gluten Free baking requires the use of processed foods that are free of traditional whole wheat flour, often used to make bread like sourdough.

This GF Banana Cake recipe uses three gluten free flours: cornstarch, almond flour and oat flour.

Other gluten free flours you might want to substitute or use when baking at home include: Buckwheat Flour, Sorghum Flour, Amaranth Flour, Arrowroot Flour, Brown Rice Flour, Teff Flour, Corn Flour, Chickpea Flour, Coconut Flour, Tapioca Flour and Cassava Flour.

What Is The Difference Between Banana Bread and Banana Cake?

As their names suggest, banana bread is a type of bread made with mashed bananas, baked in a bread pan. Banana cake is a type of cake made with banana as the main ingredient, baked in a square, circular or bundt cake pan.

The main difference between banana bread and cake is that banana bread is firmer and denser in texture than banana cake. Banana Bread is typically not served with icing while banana cake often features a glaze.

How Do You Make Gluten Free Cakes Better?

The key to producing a moist and tender gluten free cake is experimentation in the kitchen. Trying a variety of flours such rice, tapioca or potato are great ways to add texture to your cakes in the absence of gluten found in whole wheat flour.

There are lots of gluten free self raising and plain flours available on the market which help product fantastic gluten free cakes.

Do Gluten Free Cakes Rise?

If you’re having issues with your gluten free cake rising you need to assess what flour you are using as well as how much leavening agent you have incorporated into the recipe.

Dense gluten free flours such as buckwheat may hinder the rise so best to pair it with a lighter flour like oat flour. Use the denser GF flours for cookies or pancakes. Lighter flours such as millet flour or sorghum flour will create a lighter result.

Don’t forget that baking soda ha a before date. Baking powder typically keeps its leavening potential for up to 6 months. Afterwards it’s ability to leaven reduce and you’ll find muffins and cakes don’t reach their former heights.

Gluten Free Banana Cake Recipe Baking Tips

If it’s your first time baking GF Banana Cake at home be sure to review our detailed step-by-step recipe below. Here are some helpful tips and tricks to get you started.

  • We suggest using a high quality rubber spatula when scraping cake batter into baking tins.
  • You’ll save yourself time and energy by using a stand mixer to beat the cake batter. You can also use a handheld egg beater or whisk as an alternative.
  • We’ve prepared this recipe using a square cake pan but you could use a round cake pan if you prefer.
  • Use an offset icing spatula to spread the lemon glaze icing evenly across the cake.
  • If you are going to have leftovers store the cake in the fridge under a cake dome to keep it fresh.
  • We’ve blitzed the wet ingredients in a blender to save time but you can add them separately if you prefer. Mashing ripe bananas with a fork, rather than blending them until smooth, allows you to have chunks of banana in the cake.
  • Many banana cake recipes feature nuts like toasted walnuts or pecans. Feel free to add 1 cup of nuts to the batter for additional protein and crunch.
  • For a creamier and tangy icing feel free to add a few tablespoons of cream cheese to the glaze.
