Deliciously Creamy Vegan Vanilla Slice: A Plant-Based Delight!

Indulge your taste buds in a delectable treat that’s not only cruelty-free but also bursting with the classic flavours of vanilla custard. Our Vegan Vanilla Slice recipe takes the traditional pastry favourite and transforms it into a dairy-free delight that’s just as satisfying as the original. Whether you’re a seasoned vegan or just looking to explore plant-based options, this dessert is sure to win your heart (and stomach) over.

The Ultimate Creamy Vanilla Custard: Our secret to creating the luscious vanilla custard for this slice lies in the simplicity of its ingredients. A blend of unsweetened plant-based milk, cornstarch, and a touch of granulated sugar results in a silky-smooth custard that’s both rich in flavour and irresistibly creamy. The addition of vanilla extract elevates the custard’s taste, providing that unmistakable essence of warmth and sweetness.

Flaky, Golden Pastry: What’s a vanilla slice without its signature flaky pastry layers? Our recipe makes use of vegan puff pastry that’s equally buttery and airy. Once baked to golden perfection, it creates a delicate shell that encases the velvety custard, making each bite a symphony of textures and flavours.

The icing on the Cake (or Slice!): No vanilla slice is complete without its glossy, sweet icing. Our vegan version boasts a simple yet divine powdered sugar icing. With just a touch of plant-based milk and a splash of vanilla extract, it sets to a perfect, irresistible finish that’s equal parts delicious and Instagram-worthy.

Savour Every Bite: As you slice into our Vegan Vanilla Slice, take a moment to appreciate the melding of flavours and the delightful contrast between the crisp pastry and the sumptuous custard. Whether enjoyed as an afternoon indulgence, a dessert for gatherings, or a special treat for yourself, this vegan twist on a classic dessert is sure to impress both vegans and non-vegans alike.
