Fluffy Vegan Lemon Cake Recipe

0 35

New recipe for Fluffy Vegan Lemon Cake!

Zesty, lemon-y goodness that quite honestly doesn’t even need icing!

But of course I added more lemon juice and lemon zest to the buttercream for a lemon cake that is going to have you begging for more!

This time I baked all the batter into a 9″ x 13″ cake pan for an easy sheet cake

However this recipe will also yield 2-8″ cake layers or 3-7″ cake layers as well

The texture of this cake reminds me of my cream cheese pound cake from my past life

Except there is no cream cheese in this recipe, just velvety lemon good that literally melts in your mouth!

Bakes into cupcakes too, just be aware that this cake will not dome so your cupcakes will be flat

Fill the cupcake liners slightly more than half full and bake at 350°F for 18 minutes


Notes for Success:

Because of the mix method I have created here for this super fluffy cake, it is essential to have the high speed power AND balloon whip attachment of an electric stand mixer. *see video for more

When measuring cornstarch I cannot stress enough that a kitchen scale is the best way to go.

Cornstarch is a very difficult ingredient to measure consistently with a volume spoons measure, so while I list both measures below I cannot stress enough how the grams measure with a scale is going to give you the best results.

For best results I am using cake flour, if you don’t have that you can use all All Purpose flour but the total quantity should be only 3 cups total weight (360g)

All of your ingredients should be at room temperature before mixing

Since coconut oil is rarely solid, I have used it as liquid in conjunction with the vegan butter with great results

You can also use all vegan butter if you do not have coconut oil

This is a very delicate cake batter, so be sure to bake it immediately no hotter than 350°F or it will get too brown and slightly dry on the edges

For larger cakes I will turn the oven temperature down to 325°F after the first 20minutes of baking

This recipe will make 1 sheet cake baked into a 9″ x 13″ pan or it will also make 2-8″ layers OR 3-7″ layers.

bake time will vary depending on pan size so be sure to check cakes at 20 minutes
