Ingredients

For the cake:

    Dry Ingredients:

    • 350 g all-purpose flour
    • 250 g granulated sugar
    • 1.5 teaspoons salt
    • 2 teaspoons baking soda
    • 2 tablespoons poppyseeds

    Wet Ingredients:

    • 350 ml plant milk
    • 2.5 teaspoons apple cider vinegar
    • 140 ml vegetable oil
    • 2 lemons juiced and zested

    For the lemon buttercream:

    • 400 g powdered sugar sifted
    • 120 g vegan butter
    • 3 tablespoons lemon juice
    • 1 teaspoon lemon extract

    Instructions

    Preparation:

    • Preheat your oven to 180 Celsius.
    • Grease two round, 7-inch cake tins and set aside.

    Making the cakes:

    • In a large mixing bowl, combine the flour, sugar, baking soda, poppy seeds and salt. 
    • Next, mix in the plant milk, apple cider vinegar, vegetable oil and the lemon juice and zest. Mix again but don't over-mix. The flour should be just mixed in enough so that there are no lumps.
    • Equally, divide your cake batter between the two prepared cake tins. If you only have one tin, you can also bake the cakes one at a time. 
    • Bake the two cakes in the oven for 25 minutes or until a skewer comes out clean. 
    • Take your cakes out from the oven and allow them cool fully. In the meantime, let's make the lemon buttercream!

    Making the lemon buttercream:

    • In a large bowl, beat together all of the buttercream ingredients until smooth and creamy. Be patient and keep mixing, even if it feels too thick at first.

    Layering the cake:

    • If your cakes have now cooled, you can now apply the buttercream! 
    • Spread the lemon buttercream onto the flat side of one of the cakes. 
    • Place your other cake half over the filling. I like the sift some extra powdered sugar over the top of the cake.
    • Place your cake into the fridge for 30 minutes as this will thicken the filling a little. Slice and serve. 

    Notes

    • You can store this cake for up to 4 days at room temperature or for up to 2 days in the fridge.
