Preheat your oven to 340°F (170°C).
Grease two cake tins.
Combine the dairy-free milk and lemon juice, then set aside to thicken.
Sift the dry ingredients into a large mixing bowl.
In a separate bowl, mix the wet ingredients.
Gradually add the wet mixture to the dry ingredients, stirring gently until just combined.
Pour the batter evenly into the cake tins and bake for 25-30 minutes.
Prepare the frosting by mixing all frosting ingredients together, then layer and frost the cakes once they’ve cooled.
