For the Cake
2 1/4 cups Favorite GF flour blend (I used Bette Hagman’s gourmet blend- white rice, potato starch, tapioca starch)
1 tablespoon baking powder
1/2 teaspoon salt
1 1/2 tsp. egg replacer
1 tsp. xanthan gum
1 1/4 cups carbonated lemon soda (dairy-free alternative to buttermilk, carbonation lightens GF cakes)
3 ener-g foods egg replacer eggs (6 tbsp water, 4 ˝ tsp egg replacer, whisked together)
1 cup sugar (reduced due to sugar in lemon soda)
2 teaspoons grated lemon zest
1 stick (8 tablespoons or 4 ounces) earth balance vegan spread, or other GF DF butter substitute (coconut oil?) at room temperature
1/2 teaspoon pure lemon extract
1/2 tsp pure vanilla extract
For the “Buttercream”
3 tbsp sweet rice flour
1 cup milk substitute (soy, rice, almond)
3/4 cup Earth Balance Margarine *substitution not recommended*
1 tsp lemon extract
1 tsp vanilla extract
2/3 cup sugar
*fresh lemon juice* (optional- test this with a small sample of the frosting to make sure it won’t cause it to separate, or can re-congeal if whisked heavily.)
2/3 cup orange marmalade
Center a rack in the oven and preheat the oven to 350 degrees F. Butter two 9 x 2 inch round (or square) cake pans and line the bottom of each pan with a round of buttered parchment or wax paper. Put the pans on a baking sheet.
To Make the Cake
Sift together the flour, baking powder, salt, egg replacer, and xanthan gum.
Whisk together the egg replacer eggs in a small bowl.
Put the sugar and lemon zest in a mixer bowl and beat with your margarine until you have a nice, creamy texture. Add your egg replacer to the mixture and beat again until thoroughly combined. Remove the mixer bowl from the stand and gently fold in your carbonated beverage (or dairy/substitute) and any additional seasonings. *consider adding 1 tsp. cider vinegar here* Slowly sift your flour mixture into the bowl, folding in after 1/3 of the flour has been added. Add another 1/3 of the flour mixture, fold, and add the rest, folding until you have a nice cake texture. Consider adding 1/4 cup applesauce if the batter seems dry.
*Daring Baker Instructions to follow* Divide the batter between the two pans and smooth the tops with a rubber spatula.
Bake for 30-35 minutes, or until the cakes are well risen and springy to the touch – a thin knife inserted into the centers should come out clean
Transfer the cakes to cooling racks and cool for about 5 minutes, then run a knife around the sides of the cakes, unfold them and peel off the paper liners.
Invert and cool to room temperature, right side up (the cooled cake layers can be wrapped airtight and stored at room temperature overnight or frozen for up to two months).
To Make the Vegan Buttercream Recipe
*Adaption of a Vegan Cookbook recipe (La Dolce Vegan)*
Combine your milk substitute beverage and sweet rice flour in a pan and whisk until thoroughly combined. Heat on a burner and bring to a boil. Lower temperature and simmer, letting mixture thicken. Take off burner and let cool. Meanwhile, whisk your margarine, lemon extract, and sugar together in a mixer or with a hand-held mixture until combined and creamy. When the milk sauce is cool, beat into the sugar-margarine mixture and pour into a container. Cool in refrigerator until ready to frost cake (at least an hour).
To Assemble the Cake
*Daring Baker Instructions* If your cakes rose adequately, you can slice the layers in half. If not, just use the cakes as is, shaving off the bumpy top to have a nice, flat surface if desired. Spread each layer with orange marmalade and your vegan buttercream, placing cake layers together and finally topping with marmalade and then buttercream. If desired, you can place cookie cutters or biscuit cutters on the top of the cake and fill each one with a thin layer or marmalade for additional decorative pop (And flavor). Remove mold and enjoy your modern, delicious, vegan and gluten-free cake!
*Daring Baker Instructions*
The cake is ready to serve as soon as it is assembled, but I think it’s best to let it sit and set for a couple of hours in a cool room – not the refrigerator. Whether you wait or slice and enjoy it immediately, the cake should be served at room temperature; it loses all its subtlety when it’s cold. Depending on your audience you can serve the cake with just about anything from milk to sweet or bubbly wine.
The cake is best the day it is made, but you can refrigerate it, well covered, for up to two days. Bring it to room temperature before serving. If you want to freeze the cake, slide it into the freezer to set, then wrap it really well – it will keep for up to 2 months in the freezer; defrost it, still wrapped overnight in the refrigerator.
The cake was a bit heavy and dry, so the recipe could use some modification. I recommend a really good, preferrably high protein GF Flour blend. Bette Hagman’s 4 flour blend might be a winner for this. If you use a blend with xanthan gum, omit the additional xanthan gum in the recipe.
To make this cake non-vegan, 3 egg whites, whisked, would be a good substitute for the egg replacer. Additionally, you can try adding 1/4 cup applesauce to the recipe for added moisture (a simple addition, you needn’t subtract any other ingredients), or using soy or rice milk with 1 tbsp or so lemon juice added instead of the soda. If dairy isn’t a problem, you could use regular milk or buttermilk instead of the soda. I recommend adding 1 tsp. vinegar to the recipe for additional moisture, or at least retention of moisture. You might add a little extra sugar, although I found it plenty sweet as is.
