This simple and sublime cake is all of the following and more:
Made with 6 ingredients (plus water & optional salt)
Ready to bake in under 5 minutes
The cake is moist, fragrant with vanilla, and, like my 3-ingredient almond flour cookies, buttery, despite the absence of butter or any other oils. You can justify eating it for breakfast (I do; it is perfection with a cup of coffee) or serve it with seasonal fruit all spring and summer long.
How to Make the Cake
You will dirty exactly 1 bowl to make the cake. No mixers, food processors or blenders required. That merits an Hallelujah! Or, at the very least a yippee!
Third, pour the batter into an 8-inch (20 cm) round cake pan that has been lightly sprayed with nonstick cooking.
Fourth, bake the cake in a preheated 350F oven for 35 to 40 minutes until golden brown and a toothpick inserted near the center comes out with only moist crumbs attached.
Completely cool the cake in the pan before removing it. Run a knife around the edge of the pan and then invert the cake onto a flat plate or cutting board (an uneven plate, with a dip in the middle, may cause the cake to break).
Turn the cake right side up onto a serving plate, platter, or stand. If your middle name is fancy (mine is), sprinkle with some confectioners’ sugar :).
The cake is moist, luscious, and swoon-worthy.
I hope that you love this cake every bit as much as I do! The flavor can be varied with different extracts, spices, or the addition of citrus zest or fresh herbs.
And while I love my cake plain-ish, feel free to make two batches of the recipe for a layer cake, slathered and smoothed with any and all of your favorite frostings and fillings!
A few questions answered:
Is it Necessary to Use an 8-Inch Round Pan?
Pan size matters, especially with cake.
An 8-inch (20 cm) square baking pan can also be used, but keep in mind that the cake may need more baking time if the pan is glass or ceramic (instead of metal).
The cake can also be baked in a 9-inch (22.5 cm) cake pan. Begin checking for doneness at the 25 minutes mark. Note that the cake will be thinner than the 8-inch cake.
I Do Not Have Potato Starch. Can I Use Something Else?
An equal amount of cornstarch can also be used if you do not need the cake to be grain-free.
Tapioca starch will not work as a substitute. I tried. The resulting cake is sunken and gooey (I still ate some of my test batch, but it is more pudding cake, with an emphasis on pudding, than cake).
Measure the water and add the vanilla to it. Pour into bowl with almond flour mixture and whisk until blended and smooth. Spread into prepared baking pan.
Bake in the preheated oven for 35 to 40 minutes until golden brown and a toothpick inserted near the center of the cake comes out with only moist crumbs attached.
Transfer cake to a cooling rack and cool completely in pan. Run a butter knife around edge of pan and invert cake on a plate. Turn right side up on cake plate.
If desired, lightly dust with confectioners’ sugar just before serving.
Storage: Store the completely cooled cake in a covered container at room temperature for 2 days; store inanairtight container in the refrigerator for 5 days or the freezer for 1 month.
Potato Starch Tips/Options: Be sure to use potato starch, not potato flour; they are different ingredients in the U.S. Potato starch is bright white, potato flour is slightly tan in color. The cake works best made with potato starch, but an equal amount of cornstarch (if grain-free is not necessary) also work. Tapioca starch does not work as a substitute (I have tried).
This looks amazing! Can I sub a bit of oat flour along with the almond? I do not have enough! Thanks!

Hi, I was wondering if this recipe would do well with orange zest and also orange juice? Would the acidity of the juice affect it? Have you tried something like this? Also do you find that most almond flours produce the same result? Thank you!

Oh shoot, I don't have a replacement for the starch. It would require some re-testing. I do have other cakes on the site that do not have starch.
