What Makes the Texture Work
Vanilla cake is one of those bakes where texture really matters, because there is no cocoa or bold mix-in to hide a dry or gummy crumb. The main thing that makes this cake work is keeping the batter gentle: fold it just until the flour disappears, then stop while it still looks a little lumpy. I also like that it bakes in one square pan, so you get a frosted, celebration-style cake without the extra work of stacking and decorating layers.
The frosting is a classic buttercream-style mix too, which keeps things simple and sturdy without coconut cream, starch, or any unusual setting step. For a fun birthday version, add sprinkles right at the end, or use mini chocolate chips if you want more of a vanilla chocolate chip cake.
Instructions
Follow along with this step-by-step guide to make your Easy Vegan Vanilla Cake. You’ll find all the exact times, temperatures, and measurements in the recipe card below.
Step One: Make the soy “buttermilk” first, then let it sit until it lightly curdles.
Step Two: Whisk the dry ingredients in a large bowl so the raising agents are evenly mixed through.
Step Three: Add the wet ingredients and gently fold the batter together with a spatula or wooden spoon. Stop once no dry flour remains, even if the batter still has a few small lumps.
Step Four: Pour the batter into the prepared pan, smooth the top, and bake until the center springs back lightly and a skewer comes out with a few soft crumbs.
Step Five: Let the cake cool completely before frosting, otherwise the frosting can soften and slide.
Step Six: Beat the frosting until pale and fluffy, adding a tiny splash of milk only if it feels too thick to spread.
Storage
Store the frosted cake covered at room temperature for 1 day, or in the fridge for up to 3 days. For the best texture, let chilled slices sit at room temperature before serving so the frosting softens slightly. Individual slices can also be wrapped and frozen for up to 1 month, then thawed at room temperature.
Expert Tips
Sift the powdered sugar if it looks clumpy before adding it to the frosting. It makes the buttercream smoother without needing extra soy milk, which can make the frosting too loose.
FAQ
Soy milk gives the softest, most reliable crumb here. Oat milk may work, but the cake can be less predictable in texture.
This usually happens from overmixing the batter or using baking powder that has lost its strength. Fold gently and stop as soon as no dry flour remains.
An 8-inch square pan is best for this recipe. Other pans will change the cake depth and baking time, so use the springy center and soft-crumb skewer test rather than relying on the clock alone.
Serving Suggestions and More Recipes
Serve this cake at room temperature so the crumb feels soft and the frosting is easy to slice through. Add sprinkles for a birthday-style cake, or top with berries or chocolate shavings if you want a simple finish.

Easy Vegan Vanilla Cake Recipe
Ingredients
Cake
- 1 1/4 cups unsweetened soy milk 300 ml
- 1 tbsp apple cider vinegar or lemon juice 15 ml
- 2 1/2 cups all-purpose flour 300 g
- 1 1/4 cups granulated sugar 250 g
- 2 1/2 tsp baking powder
- 1/4 tsp baking soda
- 3/4 tsp fine salt
- 1/2 cup neutral oil 120 ml
- 1 tbsp vanilla extract 15 ml
Vegan Vanilla Frosting
- 1 cup firm vegan butter or margarine softened (225 g)
- 4 cups powdered sugar 480 g
- 2 tsp vanilla extract 10 ml
- 1/4 tsp fine salt
- 1–3 tbsp soy milk only if needed (15–45 ml)
Instructions
- Preheat oven to 350°F / 175°C. Grease or line an 8-inch / 20cm square baking tin with parchment paper.
- In a small bowl or jug, combine the soy milk and apple cider vinegar. Set aside for 5 minutes to lightly curdle.
- In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
- Add the soy milk mixture, oil, and vanilla extract. Use a spatula or wooden spoon to gently fold the batter together until no dry flour remains. Do not beat or whisk the batter smooth. A few small lumps are fine.
- Pour the batter into the prepared tin and gently smooth the top.
- Bake for 32–40 minutes, checking from 32 minutes, or until the center springs back lightly when touched and a skewer inserted into the center comes out with a few soft crumbs attached.
- Let the cake cool in the tin for 15 minutes, then transfer to a wire rack to cool completely before frosting.
- To make the frosting, beat the vegan butter for 2–3 minutes, until smooth and lighter.
- Add the vanilla, salt, and about half of the powdered sugar. Beat on low until mostly combined.
- Add the remaining powdered sugar and beat for 3–5 minutes, until pale and fluffy.
- Add soy milk 1 teaspoon at a time only if the frosting is too thick.
- Spread the frosting over the cooled cake. Top with sprinkles, chocolate shavings, berries, or candied citrus peel.
