Gluten-free Banana Cake with Vanilla Frosting
Mashed ripe bananas add moistness and natural sweetness to this decadent Gluten-Free Banana Cake with Vanilla Frosting. Make this cake for a special occasion and watch as it disappears! This recipe is gluten-free and dairy-free.
If you’re like me, you go through a lot of bananas at your house. Ripe bananas are naturally very sweet and the perfect texture for cakes, muffins, and even banana-sweetened cookies!
Trust me when I say you need this Gluten Free Banana Cake recipe in your life. It’s such a simple recipe but delivers with a moist and crowd-pleasing texture. And, the vanilla frosting adds extra sweetness.
Why You Need This Recipe
- This is the perfect recipe to have in your pocket for when your bananas turn too brown for eating. Overripe bananas are perfect for cakes and breads because as they ripen the starch in the banana is converted to sugar.
- This Banana Cake recipe tastes incredible dairy-free! Simply use vegan butter instead of regular butter and you’re all set.
- Bananas are cheap! They’re usually less than 90 cents per pound (and sometimes much less) which makes them a very cost effective snack and ingredient.
Ripe bananas are key for this yummy banana cake batter.
Flour helps make the structure of the cake. I used a gluten-free baking flour.
Butter or vegan butter adds fat to the cake and give it a great mouthfeel.
Vanilla extract adds depth of flavor to the cake.
Preheat the oven and spray a 9×13-inch baking dish. In a large bowl, combine the dry ingredients. I am a big fan of Bob’s Red Mill 1-to-1 Gluten-Free Baking Flour.
Add the wet ingredients to the dry ingredients and beat until there are no lumps in the batter.
Pour batter into the baking dish and bake until golden brown and a toothpick comes out clean.
Meanwhile, make the frosting. Add all the frosting ingredients to a bowl and beat until smooth and creamy adding additional almond milk if necessary.
Let the banana cake cool first before spreading on the frosting. Serve at room temperature.
Recipe Tips & Substitutions
- There are a ton of great gluten-free flours on the market to replace wheat flour. You can also try making this recipe using almond flour or almond meal. I have not tested it that way, but I think it would work!
- Feel free to add a cup of chocolate chips to the batter if you want a chocolate chip version of your banana cake.
- While a lot of cakes use brown sugar, I chose to use coconut sugar or white sugar instead.
- Want a regular banana bread recipe? Try this gluten-free banana bread.
Yes! If you aren’t on a dairy-free diet or you don’t have dairy-free milk at home, then regular milk will work just as well.
Yes, you can freeze the cake. I prefer to put the slices on a sheet pan first then put the sheet pan in the freezer. Once the slices are frozen you can put them in a freezer bag without them getting smooshed. This way you can pull out one slice at a time if you like.
I wouldn’t recommend it. Unripe bananas are not sweet or creamy which will change the overall flavor of the cake.
Yes, you can actually use frozen ripe bananas, but you’ll need to defrost them before using them in the cake. You can defrost them in the refrigerator overnight or place them in the microwave in a microwave-safe bowl until they are warmed through. Read my guide on how to freeze bananas.
