Ingredients

  • 315 ml Soy milk (1+¼ cups)
  • 1 Tablespoon Apple cider vinegar (sub white vinegar or lemon juice)
  • 350 g All-purpose flour (2+⅔ cups)
  • 1 Teaspoon Bicarbonate of soda (baking soda)
  • 1 Teaspoon Ground cinnamon (optional)
  • 200 g Caster sugar (1 cup)
  • 180 g Vegan margarine (¾ cup)
  • 1 Teaspoon Vanilla extract
  • 10 Biscoff biscuits, crushed into crumbs

For the Biscoff buttercream frosting:

  • 250 g Vegan margarine (1 cup)
  • 250 g Creamy Biscoff spread (1 cup)
  • 500 g Icing sugar (4 cups)

To top (optional):

  • 8 Biscoff biscuits
  • 1 Tablespoon Creamy Biscoff spread

Instructions

  1. Preheat your oven to 180°C/350°F (160°C/325°F if using a fan or convection oven). Grease, flour and line 3 7-inch cake pans.

  2. Mix together the soy milk and the vinegar. Whisk briefly with a fork and set to one side- this will become "curdled" and will act as vegan buttermilk.

  3. In a large bowl, mix together the flour, sugar, baking soda and cinnamon.

  4. Melt the margarine in the microwave for 20-30 seconds, or until there are no lumps left, and leave it to cool for a few minutes.

  5. Add the melted margarine to the bowl of dry ingredients, along with the buttermilk from earlier and the vanilla extract. Mix everything until well combined.

  6. Add the crushed Biscoff biscuits and fold the crumbs into the batter.

  7. Divide the cake batter between your 3 lined tins and bake for 15-18 minutes, or until a toothpick through the middle comes out clean.

  8. Leave the cakes in the tins for 10 minutes then flip them out onto a wire rack and let them cool completely.

For the Biscoff buttercream frosting:

  1. Mix the margarine and Biscoff spread together in a large bowl.

  2. Add in the icing sugar, a little at a time. Once it's all mixed in, briefly whisk the buttercream with an electric whisk or stand mixer, until fluffy.

To assemble:

  1. Spread a thick layer of the Biscoff frosting onto the first cake using a palette knife. Place the second cake on top and repeat until you have a stack of 3 iced cakes.

  2. Spread some frosting down the sides of the cake and use a scraper to smooth it out and make a crumb coat. Place the whole cake in the fridge for 1 hour, then repeat so the cake has 2 layers of frosting in total.

  3. Place 6 of the Biscoff biscuits on the cake, standing them upright in a circle (as shown in pictures). Pipe some swirls around the biscuits using the leftover frosting.

  4. Melt the Biscoff spread in the microwave for 10-20 seconds and drizzle it over the top of the cake.

  5. Crush the remaining 2 biscuits into crumbs and press the crumbs into the bottom edges of the cake.

Recipe Notes

  • The consistency of the buttercream will depend on the type of vegan margarine you use. I used Vitalite. If it's too runny, add more icing sugar until you reach your desired consistency. If it's too thick, add some plant-based milk.
  • Store the cake covered in the fridge for up to 5 days.
