Zoella calls this gluten-free angel food cake "the marshmallow cake" because it's so light, fluffy, and incredibly moist, with a hint of vanilla shining through. She savored every perfect bite: a bit of cake, a slice of strawberry, and a scrape of whipped cream.

This gluten-free angel food cake tastes just like the a classic angel food cake and 100x better than store-bought. It's lofty and airy, with the perfect balance of sweetness, making it great for toppings and delicious enough to eat on its own.

My recipe testing notes on ingredients:

The major ingredients of angel food cake are egg whites, sugar, and flour.

I recommend measuring each of the ingredients (including sugar and egg whites) by weight as angel food cake can be fussy. It's important you don't stray from the recipe else you wind up with a deflated cake.

Egg whites: There isn't any chemical leavener in this cake, such as baking soda or baking powder, so angel food cake relies on whipped egg whites for its rise. You want to make sure there is no egg yolk in your whites as it can negatively affect how well they whip up. I recommend separating the egg whites and yolks one at a time into a separate bowl before pouring it into the measuring cup so if you break a yolk, you don't ruin all your whites!
Cream of tartar: Found in the spice section of the grocery store, cream of tartar stabilizes the whipped egg whites. In doing so, the small amount of cream of tartar will reduce how much the cake deflates when you carefully fold in the flours.
Sugar: This recipe uses granulated sugar and then calls for finely grinding it in a food processor or blender. You could also opt to use superfine sugar if you have some, just be sure to measure by weight.
Superfine Blanched Almond Flour: Superfine Blanched almond flour adds moisture to the cake. It also adds a subtly sweet nuttiness that pairs well with angel food cake.
Tapioca Flour: Tapioca flour rises in the oven that helps mimic the fluffiness of a classic cake. It adds just a bit more softness and loftiness to the crumb and lends to the chewiness.
Sweet Rice Flour: Sweet rice flour is necessary for the chewy texture of this cake crumb. Sweet rice flour is distinctively different than white rice or brown rice flour. The same flour used to make mochi, its stickiness helps to bind the crumb together, creating the sponginess of a classic angel food cake. It's gluten-free baking's secret weapon.
Cornstarch: Adding cornstarch to the flour blend helps it mimic the taste and texture of a light and fluffy cake flour that leads to a tender crumb.
Xanthan Gum: This gluten-free cake relies on xanthan gum. Without it, the cake will bake up dense - it helps maintain the structure of the cake.
Vanilla Extract and Almond Extract: Both of these extracts help flavor the crumb.

There's no fat in this cake batter as it doesn't contain butter, oil, or egg yolks. As such it's the lightest, fluffiest, sponge cake ever!

How to whip egg whites for angel food cake

While some recipes call for whipping the egg whites to stiff peaks, I found that to get the most reliably beautiful gluten-free angel food cake, whipping the egg whites to medium soft peaks that come to a peak then flop over was key. Lift the whisk out of the bowl and it should create a point that lightly folds over at the tip. At this point, the eggs still have room to expand in the oven and are less likely to collapse as it bakes.

Start with fresh room temperature egg whites (from whole eggs, not from a box). To quickly bring your egg whites to room temperature, place the whole eggs in their shell in a bowl of warm water for 5-10 minutes. Then dry the eggs and crack and separate the whites from the yolks one at a time, measuring out the whites using a scale.

Small tips that make a big difference in this recipe:

Clean baking equipment well. Before starting, make sure your mixing bowl and whisk are clean of any oil or fat as it will negatively affect how well your egg whites whip. I recommend using glass or metal mixing bowls, as plastic mixing bowls are more likely to retain oils and far. You can optionally, brush them with a tiny bit of vinegar and wipe it out with a clean towel to remove any fat.
Make superfine sugar. In a food processor or blender, pulse the sugar until super fine and powdery, 1-2 minutes. Remove 1 cup and set aside.
Whip egg whites with cream of tartar. Whip egg whites and cream of tartar on medium-low for about a minute until the eggs are foamy.
Slowly pour in sugar then extract. Very slowly pour in the 1 cup of fine sugar you pulsed. Whip until medium soft (but not stiff!) peaks form. When you lift the mixer, a peak should start to stand up at a point, but then instantly fold over onto itself. Just before it's done, add the vanilla and almond extracts and mix them into the egg whites.
Slowly sift flours into egg whites. Using a fine mesh sieve, sift the flour mixture into the egg whites in four batches, using a silicone spatula to fold the dry ingredients in slowly and carefully.

Why use a tube pan for angel food cakes:

For an angel food cake, you need a tube pan (also called an angel food cake pan) with a removable bottom. Look for one that is not non-stick as it's essential that the cake batter can cling to the sides and rise up the sides as it bakes. For this reason, you also should not grease a tube pan when using it for an angel food cake.

I also recommend a light-colored tube pan so the outside of your cake does not get too dark while the crumb bakes. This is the tube pan I use, which also has little feet that are helpful when you turn the cake upside down to cool!

The center hollow tube of the tube pan helps support even heat distribution and strengthens the cake as it rises.

While it also has a center tube, do not use a bundt pan. Since you do not grease the pan for an angel food cake, the cake will stick to all the crevices of a bundt pan when you try to remove it!

How to tell when angel food cake is done

For this gluten-free angel food cake, error on the side of over-baked rather than underbaked. An underbaked angel food cake won't hold its structure and will come out overly moist and gummy. To tell when your cake is done, your cake should spring back when gently touched in the middle and a tester should come out clean when inserted.

When in doubt, keep it in for a few minutes longer. I've yet to overbake this angel food cake!

Cool angel food cake upside down

As soon as the cake comes out of the oven, invert the cake pan onto a wire rack to cool completely (1.5-2 hours). Cooling the can upside down ensures that the cake does not sink onto itself while cooling. This ensures the best and most fluffy texture.

If the middle of your tube pan does not touch the counter, support it with an upside-down bowl or cup while it cools (see picture). This ensures the cake maintains its structure while it cools.
