This ultra-moist gluten-free vanilla cake recipe has a light and tender buttery crumb. With a classic American buttercream, this cake tastes like a soft sugar cookie. Bake it up can as a layer cake or a sheet cake for the perfect gluten-free birthday cake for your party!

As a gluten-free baker, I'm calculated in my kitchen. I plan and research and take extensive notes. I'm precise and scientific. And yet, somehow, when I let go of all that, magic still happens. Like this gluten-free vanilla cake recipe.

It's sheer perfection and was simply the result of channeling my inner childhood baking whimsy. Here's to doing more of that!

Easy Gluten-Free Vanilla Cake Recipe

This perfect gluten-free vanilla cake recipe was the happiest of accidents. I needed a base sheet cake for a client shoot, so I decided to throw caution to the wind and experiment with something entirely new. I roughly drew inspiration from Sally's Baking Addiction's Vanilla Sheet Cake, trying a gluten-free spin (with more modifications based on my mood because I can never leave well enough alone).

If the inside didn't bake up great, so what?! I didn't need it to! In fact, I've already got a gluten-free vanilla cupcake recipe I love. 

What Does Gluten-Free Birthday Cake Recipe Taste Like?

The result was so much better than I expected. This gluten-free yellow cake recipe tastes like a super moist sugar cookie topped with buttercream and sprinkles. I made it again. And again. I couldn't stop.

I've now tested and refined this cake 14 times in various forms as a layer cake, a sheet cake, and cupcakes. This cake now rivals my gluten-free chocolate cake recipe. 

Now I've got two back-pocket perfect gluten-free cake recipes, which means I've also got crucial decisions to make for all future birthday celebrations. Or, you know, maybe I'll just make both. No one ever complained about too much cake, right?

Can I use an all-purpose blend for gluten-free cake flour?

Rather than using an all-purpose gluten-free baking flour, I prefer to make my own blend of gluten-free cake flour. There are a few reasons for this.

The first is that not all pre-made gluten-free flour blends are the same. One might work for a recipe, but using a different brand/blend will produce entirely different results.

Additionally, I've found the best results when I use a different blend of flours depending on what I'm baking. What works for a fluffy cake recipe is different than what works great for chewy crisp cookies. While an all-purpose blend may work great for one recipe, it won't work great for all recipes. 

Finally, most pre-made gluten-free flour blends rely heavily on starches and gums without as many nutritional or flavorful flours. When you select gluten-free flours for the specific recipe you're making, you can optimize for that recipe both in terms of texture, but also flavor and nutrition. 

That being said, I have tested an early iteration of this cake with Bob's Red Mill 1-to-1 all-purpose gluten-free flour blend and it was delicious. If that's the route you'd like to go, I recommend substituting all of the flours by weight.

Best Gluten-Free Flour for Cakes

For this cake, I use the following flours for my blend and recommend a few substitutions if you can't find that particular flour. A note about substitutions: I have not tested this particular cake with any of these substitutions, so your results and baking time may vary. These are just my recommendations based on my experience with gluten-free cake baking.

Sorghum Flour

Sorghum a wholesome whole grain flour. With slightly sweet notes, sorghum flour adds flavor depth. Sorghum also helps creates a very moist crumb. I exclusively use Bob's Red Mill sorghum flour.

• Sub in by weight: you can substitute gluten-free oat flour by weight or Bob's Red Mill 1-to-1 all-purpose gluten-free flour blend

Sweet Rice Flour

Also called mochiko or glutinous rice flour, sweet rice flour is distinctively different than white rice or brown rice flour. Sweet rice flour is the same flour used to make mochi, and as such, its stickiness helps to bind the cake together, creating chewiness like a classic cake recipe. I prefer Koda Farms Mochiko for cake, but have also tested it Bob's Red Mill Sweet Rice Flour.

• I don't recommend substituting the sweet rice flour as I find it's essential to the recipe, but you might have success replacing it with Bob's Red Mill 1-to-1 all-purpose gluten-free flour blend.

Tapioca Flour/Starch

I've added tapioca flour here for both chewiness and to help mimic the fluffiness of a classic cake. I exclusively use Bob's Red Mill tapioca flour (and, in fact, I find others to be too gritty)

• Sub in by weight: arrowroot flour, potato starch, or Bob's Red Mill 1-to-1 all-purpose gluten-free flour blend.

Millet Flour

Millet flour is a neutral flour here to balance the others out so the cake isn't too moist or gummy. I exclusively use Bob's Red Mill millet flour. 

• Sub in by weight: teff flour (though your cake will be noticeably darker), light chestnut flour, brown or white rice flour, or all-purpose gluten-free flour.

How to Make Gluten-Free Cake

Here are my biggest tips for making a light, moist, fluffy gluten-free cake.

Use high-quality ingredients

From gluten-free flours to vanilla extract, it's important to choose ingredients that will give you the best results and flavor. In the recipe below, I've linked to the specific brands of flours and extracts I recommend.  

Room temperature ingredients

The reason most baking recipes call for room temperature ingredients is that room temperature ingredients blend together better, creating an emulsion that's key for trapping air into your batter. Here are some tips to quickly bring ingredients to room temperature. Room temperature should be around 65-70°F, and I use a thermometer to quickly check the temperature of my ingredients.

• Eggs. Place your cold eggs in a cup or bowl of very warm (not hot) tap water for 5-10 minutes. 
• Butter. Slice the butter into cubes to bring it to room temperature quickly. Or, alternatively, keep the stick whole and microwave it for 5-8 seconds, flip the stick, and repeat. 
• Milk. Microwave milk for 5-8 seconds at a time, stirring after each time, until it is room temperature.
• Sour cream. Sour cream will curdle when heated, so I use one of two methods to bring it to room temperature quickly. For the first method, I spread it out on a plate in a thin later for 20 minutes. If I don't have that much time, I spread it inside a bowl into a thin layer and microwave it for 5-7 seconds, stirring, and re-spreading. Repeat until room temperature.

Use a scale

The way you scoop and measure a flour can drastically change the weight of a cup of flour. This is exacerbated with gluten-free baking, in which you measure out multiple types of flour. Moreso, different brands have different coarseness of the grind, which also affects how much a cup of flour weighs. Use a scale to make sure you’ve got accurate measurements.

I actually recommend using a scale for even the milk and sour cream because it's so much faster and you can be more precise!

Line your cake pans

Greasing your cake pans with oil or butter and lining them with either a round or a sling of parchment paper will ensure your cake easily releases from the pan without getting stuck.

Rap cakes on the counter

Before baking, pick your pans up about 1-2 inches and rap them on the counter to help release any large air bubbles. 

How do I make my gluten-free cake more moist?

Adding more fat to gluten-free cakes will make the crumb more moist. There's a delicate balance between adding more fat and losing the light fluffy quality of the cake.

In this cake, I found that adding more sour cream and less butter produced a cake with a beautifully light and fluffy crumb that's still incredibly moist.y

Does Gluten-Free Cake Need Xanthan Gum?

Yes. In this cake, the xanthan gum is not optional. While there are some recipes where xanthan gum is not required but will help with a lighter fluffier crumb (like my gluten-free chocolate cupcakes and gluten-free vanilla cupcakes), this gluten-free vanilla cake does. I tested this cake twice without xanthan gum and both times the cake failed. The batter was gritty and too runny and the cake baked up flat and dense. 

If you’re just starting out with gluten-free baking, I understand that the hefty price tag on xanthan gum might steer folks away from using their own homemade flour blends that call for it.

If you're in that camp, just know it lasts for a long time! I keep it in my fridge and a bag lasts me almost 2 years, so if you plan on getting more serious about gluten-free baking, a little goes a long way. Each recipe typically only calls for ½-1 teaspoon.

Can you Freeze Gluten-Free Birthday Cake?

You can make gluten-free vanilla cake layers in advance and, once cool, wrap them well in plastic wrap before freezing them. If you're just freezing the cake for a couple of days, plastic wrap is fine, but if you plan to freeze it for longer, stick the cake in a gallon freezer bag to prevent freezer burn. 

When you're ready to frost the cake, pull it out of the freezer and frost it frozen. This will actually make frosting it so much easier and will help you get that super smooth frosting look!

Let the frosted cake sit at room temperature to completely defrost for 1.5-2 hours before slicing and serving. 

Storing Leftover Gluten-Free Butter Cake

Store any cake leftovers in an air-tight container at room temperature for up to 2 days.

Because this is a butter cake, it's best served at room temperature. It's also more prone to drying out when it sits uncovered or when stored in the fridge. 

How to Cut Perfect Cake Slices

With layer cakes, it's easy to make a mess when slicing through the layers. With soft frosting, the top layer can push frosting in every which way. 

To make perfect clean slices, store the cake in the fridge for just 15-20 minutes before serving. This will firm up the frosting without chilling the cake. Slice the cake right out of the fridge, wiping the knife after each cut. 

Can I bake this as a gluten-free sheet cake?

Yes! In fact, I first developed this cake as a gluten-free vanilla sheet cake in a 9x13 baking pan. I've tested it just as many times as a sheet cake and, depending on the occasion, sometimes I prefer the simplicity of a sheet cake. No crumb coat and smoothing the sides - just swirls and sprinkles.

You'll need much less frosting for a sheet cake since you won't be layering. In fact, you can frost it right there in the pan if you like! 

Can I bake this as gluten-free cupcakes?

You can absolutely bake this cake as gluten-free cupcakes. The full recipe will make 22 cupcakes.

You'll need slightly less frosting for cupcakes than for the full layer cake and they bake up just a bit quicker too.
