How to Make Vegan Key Lime Cake
Preheat your oven to 350°F (180°C) and prepare two 8-inch round cake pans by greasing them with non-stick spray. This ensures a smooth release after baking.
Sift the all-purpose flour into a mixing bowl and add the white granulated sugar, baking soda, and salt; whisk together until well combined. This helps the dry ingredients mix evenly, ensuring a fluffy cake.
Combine the wet ingredients by adding soy milk, canola oil, vinegar, lime juice, and lime zest to the bowl. Mix gently until the batter is just combined avoid overmixing for the best texture.
Divide the batter evenly between the two prepared 8-inch round cake pans. A spatula can help ensure equal portions, allowing for even baking.
Bake for 30 minutes, or until a toothpick inserted into the center comes out clean. You ll want them to be lightly golden on top.
Cool the cakes for a few minutes in the pans before transferring them to a wire cooling rack. Let them cool completely before frosting to prevent the icing from melting.
Prepare the frosting by beating softened vegan butter, powdered sugar, and lime juice together in a stand mixer until the mixture is smooth and fluffy. This creates a light frosting that spreads beautifully!
Frost your cooled cake layers by spreading the delicious lime frosting evenly over the top of one layer, placing the other layer on top, and finishing with more frosting on the top and sides.
Slice and serve your beautiful Vegan Key Lime Cake, enjoying each refreshing bite!
Optional: Garnish with extra lime zest for an added pop of color and flavor.

For room temperature storage, cover the cake and keep it in a cool, dry location for up to 3 days.
