- 440 g all-purpose flour
- 1 tbsp cornstarch

- 300 g sunflower oil (or canola oil)
- 400 g granulated sugar
- 250 g vegan yogurt, room temperature
- 1 tbsp lemon juice (or apple cider vinegar)
- Zest of 2 lemons
- 300 ml unsweetened oat milk, room temperature (or any plant-based milk)
- 100 g (3/4 cup) frozen blueberries
Lemon Buttercream Frosting
- 500 g vegan butter, softened
- 420 g powdered sugar
- 4–5 tbsp oat milk, room temperature (or any plant-based milk)
- 1–2 tbsp lemon juice
- Zest of 2 lemons

- 280 g blueberry jam (+ extra for decorating the cake – optional)
Instructions
- Preheat the oven and prepare cake pans: Preheat the oven to 355°F (180°C). Grease three 8’’ cake pans with oil or vegan butter and line the bottom with parchment paper to prevent sticking. Set aside for later use.
- Make the cake batter: In a medium bowl, whisk together the all-purpose flour, cornstarch, baking powder, baking soda, and sea salt. In a large bowl, combine sunflower oil, granulated sugar, vegan yogurt, lemon juice, and lemon zest; whisk until well combined. Stir in the unsweetened oat milk. Gradually sift in the dry ingredients and mix until just incorporated. Finally, gently fold in the frozen blueberries to distribute evenly without breaking them.
- Bake the cake: Evenly divide the batter among the prepared cake pans. Bake in the preheated oven for about 25 minutes or until a toothpick inserted into the center comes out clean. Remove from the oven and let the cakes cool in the pans for 10 to 15 minutes. Then transfer them to a wire rack to cool completely.
- Make lemon buttercream frosting: Place the softened vegan butter in a large bowl or a stand mixer fitted with a whisk attachment. Beat on high speed for 2 to 3 minutes until fluffy and lighter in color. Sift in half of the powdered sugar and mix to combine. Gradually add the remaining powdered sugar, mixing well. While mixing, add oat milk and lemon juice one tablespoon at a time until the frosting is smooth, fluffy, and spreadable. Stir in lemon zest for extra flavor.
- Assemble and decorate the cake: Using a sharp knife or thread, level the tops of the cakes to ensure even layers. Place one cake layer on a serving plate and spread an even layer of frosting on top. Create a small well in the center and fill it with blueberry jam. Repeat the process with the second cake layer. Place the third cake layer upside down on top, making sure it’s level. Apply a thin crumb coat of frosting around the sides and top, scraping off excess frosting. Chill the cake in the fridge for 45 to 60 minutes to set the crumb coat. Remove from the fridge and apply a thick final layer of frosting, reserving some for decoration. Add extra blueberry jam decoratively on top and sides if desired, then pipe swirls with remaining frosting to finish. Slice and serve!
Notes
- Use room temperature ingredients to ensure a smooth batter and frosting.
- Frozen blueberries prevent the batter from turning blue and keep the berries intact.
- Make sure the cakes are completely cooled before frosting to avoid melting the buttercream.
- If you prefer, you can substitute oat milk with any other plant-based milk.
- Chilling the cake after the crumb coat helps achieve a smooth final finish with the frosting.
- The frosting can be adjusted in consistency by varying the amount of oat milk added.
- Extra blueberry jam can be heated slightly for easier spreading if needed.
