Vegan Vanilla Sponge Cake with Buttercream Frosting and Strawberry Jam: A Game-Changing Dessert Recipe for Those with Dietary Restrictions

To Make the Cake:

1. Preheat your oven to 340 degrees Fahrenheit and line two 8-inch round cake pans with parchment paper.
2. Combining the almond milk and apple cider vinegar in a bowl, whisk thoroughly to achieve a smooth, fully incorporated mixture. Let milk sit at room temperature for about 10 minutes to curdle. This creates a vegan buttermilk.
3. With the buttermilk prepared, combine it with the oil, sugar, and a hint of vanilla extract. Whisk at high speed for approximately 2-3 minutes, or until the mixture is thoroughly incorporated.
4. Separately, whisk together the flour, baking soda, baking powder, cornstarch, and salt to ensure a smooth blend. Mix just until the flour is fully incorporated, then stop.
5. Gently incorporate the dry ingredients into the wet mixture, folding until a uniform consistency is achieved.
6. Divide the batter evenly between the prepared cake pans. Carefully tap each tin against the worktop to ensure any air bubbles are released before proceeding.
7. Pop the cake tins into the preheated oven and bake for 20 to 22 minutes. When cooked, you’ll know they’re done by inserting a knife or skewer, which will come out clean, accompanied by an elasticity that yields to pressure.
8. Allowing the cakes to reach room temperature on a wire rack facilitates even cooling, while storing them in an airtight container at this stage preserves their freshness until ready for frosting.

To Make the Frosting:

1. With a stand mixer or handheld electric whisk, whip the softened butter on high speed until lightened, before gradually introducing the vanilla extract and powdered sugar in a slow, steady stream to minimize sugary fumes.
   Add milk if needed.
2. Trim any excess cake to achieve a smooth, even surface using a razor-sharp knife.
3. Carefully stack the cake layers, ensuring an even distribution of both rich buttercream and sweet jam to create a harmonious balance of flavors and textures. To ensure a perfectly levelled cake, it’s essential to flip the finished dessert upside down immediately after removal from the oven, allowing the cake to settle and form a flat surface.
4. Allow the cake to be fully crumb-coated, then refrigerate it for approximately one hour to allow the coating to set and the cake to chill.
5. Once the frosting has fully set, add a concluding layer of buttercream and embellish as desired. Freshly prepared cakes can be served immediately; alternatively, they may be stored in an airtight container at room temperature or refrigerated, with the buttercream firming to perfection over time.
