Hello my angels 👋

Before we begin, I need to give you fair warning.  This recipe for Keto Angel Food Cake is very difficult to make.  It has a meringue batter, so it is fraught with danger.  You may do everything right, but a butterfly flapped its wings in Paraguay, and as a result, your cake fell.

It just happens.

But it’s not too late to turn back!  

No need to trouble yourself with Angel Food Cake. I’ve got some lovely Keto cake recipes on the site. My Toasted Almond Torte, Lemon Pound Cake and Chocolate Lava Mug Cake all have very high rates of success. If you give up now, I won't blame you.

But if you insist on going forward, let's talk ingredients.

🥣 Ingredients

• Egg Whites- Make sure to use fresh eggs at room temperature to get the maximum volume. And always buy large size eggs because all recipes are designed to use that size.
• Almond Extract- This is the primo flavor for an angel food cake.
• Vanilla Extract- This flavor is negotiable, but I recommend it as a compliment to the almond extract.
• Cream of Tartar- This will act to stabilize the egg whites as you whip them.
• Swerve Granular- I like using this erythritol sweetener blend because it is the closest taste to real sugar, but you can also use Allulose if you prefer it.
• Arrowroot Starch- It might surprise you that the dry ingredients include arrowroot starch and not almond flour or coconut flour, but those flours are too heavy to use in this Keto Angel Food Cake. Arrowroot Starch is light and airy and yet still low in carbohydrates.

📖 Instructions

1. Pre-heat oven to 350 degrees F and place the rack in the middle
2. Separate eggs, being careful not to get any yolk into the whites.  Crack an egg over one small bowl, separate the egg, and transfer the egg white to a large mixing bowl.  Repeat with remaining eggs. This way, if you get a little yolk in the egg white, you can easily throw it out before it contaminates the other egg whites.
3. In a medium-sized bowl, sift together ¼ cup of the sweetener and 1 cup of the arrowroot starch.
4. In the large mixing bowl, use a stand mixer or an electric mixer to beat the egg whites on medium-high speed until foamy, 30 seconds.  Keep the speed at medium-high for the rest of the recipe.
5. Add cream of tartar, almond extract, and vanilla extract and beat until soft peaks form.
6. Slowly beat in ½ cup sweetener, 1 tablespoon at a time, until soft glossy hills form.
7. Slowly beat in arrowroot mixture, ¼ cup at a time, until smooth.
8. Pour the batter into a 12-inch ungreased tube pan and run a fork through the batter to pop any large air pockets.  Smooth the top of the batter with a spatula.
9. Bake for 35-40 minutes until the cake has doubled in size and the top is a medium brown.
10. Immediately invert the angel food cake pan.  Air needs to be able to circulate around the pan as it cools.  If the pan has legs, do nothing, but if not, hold the pan above the counter, using a bottle or can.  Cool for 1 ½ - 2 hours until completely cooled.  
11. Use a knife to carefully cut around the sides of the pan to release the cake.  Pull apart the two pieces of the pan.  Slice around the top of the pan.  Slice around the inner tube of the pan.  Carefully release the cake.  
12. To make the whipped cream, add heavy whipping cream and powdered sweetener to a large bowl.  Mix with an electric mixer until stiff peaks form, 2 minutes.
13. Garnish the top with berries, fresh herbs, and edible flowers. 
14. Slice the cake using a serrated knife.

🎂 The right pan to use

• You need to use the right kind of pan, if you are going to release the cake.  Tube pans are made specifically for sponge cakes.  They have two pieces and often have legs so that air can circulate around the pan as the cake cools. 
• If your tube pan doesn’t have legs, then you can invert the cake and use a bottle or can to hold it above the counter.  Invert the cake immediately after it comes out of the oven and let it cool for 1 ½ - 2 hours before serving.    
• Don’t grease your pan.  The Keto Angel Food Cake rises by clinging to the sides of the pan as it bakes.  So if it’s greased, it doesn’t have anything to cling to, and it won’t double in height as it should.

🥚 How to whip the eggs

• Use room temperature eggs. If you can't wait for them to come up to room temp, you can submerge them in warm water for a few minutes.
• Use an absolutely clean glass or metal bowl to whip the eggs in. Even a trace of grease can ruin the whole shebang.
• Don’t over mix the egg whites.  Start out with soft peaks, not stiff peaks like a whipped cream.  After you’ve added the sweetener, you should have soft glossy hills of batter.
• Once you’ve poured the batter into the pan, run a fork through it to pop any big air pockets.  Smooth the top flat with a spatula.
• And try not to waste the egg yolks, if you can help it. Why not make them into a Hollandaise Sauce or some Keto mayo? 

🔪 Releasing the cake

• Take your time cutting the Keto Angel Food Cake out of the pan.  You want the outside of the cake to be evenly brown.
• If the sides of the cake don’t release from the pan as beautifully as you’d like, then whipped cream is very forgiving.  Just double the whipped cream and frost the sides of the angel food cake.

🥛 The Whipped Cream

• The whipped cream is easy to make, at least. All you need to do to make your own whipped cream at home is to use an electric mixer to whip together heavy whipping cream and powdered sweetener until stiff peaks form. This should only take you 2 minutes, tops.

🍓 Garnishes

• Garnishes really make this low carb Angel Food Cake sing.  Some topping ideas: raspberries, blackberries, strawberries, blueberries, fresh mint, rosemary, sage, and edible flowers.  Just remove the herbs and flowers before you slice the cake.

😋 Cutting and eating the cake

• Slice the cake carefully with a serrated knife.  The outside should be crisp and hard and the insides should be chewy and spongey.  
• Eat the Angel Food Cake on the same day that you make it, because it will harden overnight.

💬 Any questions?

And that, as they say, is that. 👩‍🍳

But they really should, because the taste is just... heavenly. 👼
