I am committed to bringing you other great keto recipes that help you make healthy and easy keto meals during this time of uncertainty as well. It won’t be all cakes and cookies and butterflies over here, I promise. Be sure to check out this collection of easy keto dinners if you need a little inspiration.
The perfect keto angel food cake
It took me a long time to get this right, my friends. A lot of attempts, a lot of failures, and a lot of research. And a lot of sunken, overly dense keto angel food cake.
It all tasted good, so rest assured that it was not wasted. We found good homes for the failed cakes. Most notably, in our bellies!
I have to admit, I was very close to giving up. But I then I had a major breakthrough when I made the Chiffon Cake in The Ultimate Guide to Keto Baking. After a few attempts on that cake, I got the proportions of flour and protein powder JUST right.
And I knew I had to give keto angel food cake one more try.
This cake truly is keto-friendly!
When I was doing research on how to make angel food cake, I came across a number of cakes that called themselves keto.
I have to admit, was aghast that they all took either arrowroot starch or tapioca starch. And not just a little, either. One recipe took a full cup of starch.
I knew it had to be possible to make it without any starch whatsoever. And turns out I was right!
How to make keto angel food cake
Even conventional angel food cake takes some effort to make properly. This is a good baking project when you have some time on your hands and are up for a challenge! A few important do’s and dont’s:
Don’t grease the pan
Angel food cake needs to “climb” the sides of the pan and greasing the sides interferes with this.
Do line the bottom with parchment
This is critical for the easy release of the cake once it has cooled. I have clear instructions about how to line a tube pan with parchment in the recipe notes.
Do consider weighing your dry ingredients
Accuracy is crucial for angel food cake recipes, which is why I provided the exact weights for my almond flour and protein powder.
Do use protein powder
Protein powder is part of what allows keto angel food cake to rise and have the proper structure. You will need it for this recipe and I recommend egg white protein. Whey protein should also work but I haven’t tested that out properly.
Do sift your flour mixture properly
Sifting the flour thoroughly helps the cake be lighter and fluffier. If you don’t have a good sieve for sifting, then spend some time fluffing up the flour mixture with a fork.
Don’t invert the cake pan right away
Traditional angel food cake has you inverting the pan the minute it comes out of the oven, to avoid heaviness at the bottom of the cake. But I found it was important to let the cake cool for 20 minutes before inverting it.
How to store keto angel food cake
One of the great parts about this cake is that it can be made ahead and frozen! Just be sure to wrap it up tightly. I have half of my last cake in there as I write this.
If you aren’t planning on freezing it, it’s fine on the counter for 4 days, covered. Place plastic wrap over any cut ends to keep them from drying out.
What to do with leftover egg yolks
I have many answers for that! Check out these 35 great keto recipes for leftover egg yolks.
You can also simply add a few extra yolks to an omelet or to my Easy Taco Pie. The yolks will keep in your fridge for 3 days or so. I store mine in glass jars.
Bon appetit! I hope you enjoy this recipe.
Keto Angel Food Cake
- Place an oven rack in the second lowest position and preheat the oven to 325F. Line the bottom with parchment paper (see recipe notes). Do not grease the pan.
- In a medium bowl, whisk together the granular and powdered sweeteners.
- In a large bowl, whisk together the almond flour, protein powder, half the sweetener mixture, and the salt. Use a sieve or strainer to sift the flour mixture into another large bowl. Do this back and forth between the bowls 3 times.
- If you do not have a sieve, simply use a fork to fluff up the mixture for several minutes, to break up clumps and make it lighter and airier.
- In another large bowl, beat the egg whites with the cream of tartar until frothy. With the beaters running, slowly add the remaining sweetener until the whites hold medium peaks (the tips should flop over slightly when the beaters are lifted).
- Add the extracts and continue to beat until the whites hold stiff peaks (tips should stand up straight when beaters are lifted).
- In four separate additions, carefully fold the flour mixture into the egg whites until well combined (a large silicone spatula works best for this). Be sure to scrape the bottom of the bowl well to mix in any ingredients that may have settled there.
- Spread the batter in the prepared pan and smooth the top. Wipe off any drops of batter from the sides, and lightly tap the pan on the counter a few times to release any air bubbles.
- Bake for 40 to 50 minutes, rotating the pan halfway through baking, until the top is uniformly golden and springs back when lightly pressed.
- Remove and let cool in the pan 20 minutes, then turn the pan upside down and let cool completely.
- Run a sharp knife around the inside of the pan, and around the tube in the center, to loosen the cake. If the pan has a removable bottom, you can simply push up to release the cake. Otherwise, invert the pan over a cake plate and tap the bottom to release the cake.
