Moist Vegan Lemon Cake Recipe with Zesty Glaze

Vegan lemon cake: bright, fluffy, and irresistibly fresh. This tender cake is bursting with lemon flavor and a light buttercream that makes it a perfect go-to dessert for gatherings, warm evenings, or a special weekly treat.

This vegan lemon cake is designed to feel like a sunny evening on your plate—zesty, fragrant, and satisfyingly moist. The crumb stays soft while the lemon adds a lively brightness that cuts through the sweetness of the frosting. Whether you serve it at a party or enjoy a slice with your afternoon tea, it’s a crowd-pleaser that’s simple to make and easy to adapt.

The cake layers are light and airy, and the lemon buttercream frosting is smooth and creamy. The recipe scales well: make two 9-inch layers for a classic layer cake, or halve the recipe for a single-layer version. You can also turn the batter into cupcakes if you prefer individual portions.

Ingredient notes

• Unsweetened plant milk: any unsweetened plant milk works. Soy milk tends to yield the best texture for baking.
• Apple cider vinegar: this reacts with the plant milk to create a buttermilk-like texture. White vinegar or lemon juice can be used instead.
• All-purpose flour: this recipe was developed with all-purpose flour. If you use other flours, you may need to adjust quantities and baking time.
• Granulated sugar: white granulated sugar works well, but you can substitute brown, coconut, or cane sugar for a different flavor profile.
• Oil: neutral oils like canola or sunflower are ideal. Use melted coconut oil if you prefer, and avoid extra-virgin olive oil for a neutral flavor.
• Vanilla extract: enhances the flavor. Homemade or store-bought vanilla are both fine.
• Lemon juice: fresh lemon juice is best for bright, natural citrus flavor.
• Vegan butter: needed for the frosting. Use a quality vegan butter for the creamiest results.
• Powdered sugar: for a smooth, stable buttercream. You can make your own powdered sugar by blending granulated sugar with a little cornstarch.

Dietary variations

• Gluten-free: use a reliable gluten-free flour blend designed for cakes.
• Soy-free: select soy-free plant milk and soy-free vegan butter to make the cake soy-free.

How to make vegan lemon cake

Follow these clear steps to bake the cake layers:

• Preheat the oven to 350°F (180°C). Grease two 9-inch (23 cm) cake pans and optionally line the bottom with parchment paper.
• In a jar or small bowl, whisk the plant milk with the vinegar and let it sit at room temperature for 5 minutes to thicken and slightly curdle—this acts like vegan buttermilk.
• In a large mixing bowl, whisk together the dry ingredients: flour, sugar, baking powder, baking soda, and salt.
• Add the oil, vanilla extract, lemon zest, lemon juice, and the plant milk-vinegar mixture to the dry ingredients. Stir until the batter is smooth and well combined.
• Divide the batter evenly between the two prepared pans and smooth the tops.
• Bake for 30–40 minutes, or until a toothpick inserted into the center comes out clean. Baking times vary by oven.
• Allow the cakes to cool in the pans for 15 minutes, then transfer to a cooling rack and cool completely before frosting.

Make the lemon buttercream frosting:

• Beat the vegan butter in a mixer or with a hand mixer until light and fluffy.
• Add lemon juice, lemon zest, and vanilla extract, and beat briefly to combine.
• Gradually add powdered sugar, about ½ cup (120 g) at a time, until the frosting is thick and creamy.
• If the frosting is too thick, add a splash of unsweetened plant milk. If it’s too thin, add more powdered sugar to reach the desired consistency.
• Frost the cooled cake, spreading a generous layer between the two layers and covering the top and sides as desired.
• For best presentation, refrigerate the frosted cake for about 30 minutes before slicing, though this is optional.

How to store

• Refrigerator: store the cake in an airtight container in the fridge for 3–5 days.
• Freezer: freeze unfrosted layers in an airtight container for up to one month. Thaw in the refrigerator and frost just before serving.
