keto Sponge Cake

Adapted from:http://joepastry.com/2009/how_to_make_genoise_batter/

This recipe makes one 18" by 13" thin sheet cake / OR one 9" round cake / OR 10 cupcakes

Servings: 10 
 


140g almond flour OR other nut flour

10g psyllium husk powder OR 25g coconut flour
(optional) 30g butter (Note: leave out the butter completely if you are making tres leches cake or any other dessert in which the sponge cake needs be soaked in lots of liquid)
1/2 teaspoon salt
6 large eggs (~55g each)
100g powdered isomalt or sorbitol (for a lower-carb cake, you can substitute all of this for powdered erythritol or xylitol, but the resulting texture and structure will not be quite as good)

100g powdered erythritol or xylitol

(optional) 1 teaspoon vanilla

1 tsp. baking powder



Preheat the oven to 170C/340F.
Line a baking pan with baking paper or a non-stick baking mat.
Sift the almond flour, psyllium husk, and baking powder together into a medium bowl.

Melt the butter in a small saucepan and set aside.

Pour the sweeteners into the mixer bowl, add the eggs and beat the mixture on medium high until it’s very light and foamy, about triple its original volume (this will take  at least 5 minutes with a stand mixer).

Add the vanilla and salt and beat an additional 10-15 seconds.

Pour a cup or so of the egg foam into the cooled melted butter and stir it until it’s completely incorporated, then gently pour the mixture back into the mixer bowl (this eases the incorporation of the butter into the batter).

Next, re-sift the flour substitute mixture into the mixer bowl and carefully fold until the flour mixture and the butter-egg mixture are completely incorporated. Gently pour the batter into the prepared pan.

Bake until the cake is a pale gold color and springs back lightly when touched. About 15-20 minutes for cupcakes, 25-30 for a large single cake.

ABOUT TPH

When you're as obsessed with sweets as I am, skipping dessert is not an option, but all the "sugar-free" treats I find in stores/restaurants never quite taste like dessert. After discovering that GOOD low-carb dessert recipes are so hard to find, I started experimenting and creating my own. TPH exists so that diabetics, carb-resistant people like me, and anyone else looking to avoid sugar can enjoy truly decadent desserts that won't cause insulin resistance or tooth decay.
