Valentines red sheet cake with buttercream hearts

Vegan Red Velvet Sheet Cake


Need an easy Valentines cake? I got you! This Vegan Red Velvet Sheet Cake is made with moist, chocolate-flavored red cake frosted with a creamy cream cheese icing, with mini hearts on top.


Units Scale

Ingredients for the cake

  • 230ml of dairy-free milk (I use Califia Oat Barista Blend drink)
  • 1 teaspoon of apple cider vinegar
  • 250g of self raising flour
  • 15g of cocoa powder
  • 100g of caster sugar
  • 1/2 teaspoon of baking powder
  • 1/2 teaspoon of bicarbonate of soda
  • 70ml of sunflower oil
  • Red food gel

Ingredients for the frosting

  • 80g of dairy-free block butter
  • 20g of dairy-free cream cheese
  • 230g of icing sugar
  • 1 teaspoon of vanilla extract / vanilla paste
  • Pink food gel
  • Dairy-free milk (if needed) I used Califia Oat Barista Blend Drink.


Method (Cake)

  1. Preheat your oven to 180ºC fan and line an 8 x 8 inch square cake tin with greaseproof paper. Allow the paper to hang over the tin slightly, this makes it easier to remove the cake when baked.
  2. In a bowl, combine the dairy-free milk with the apple cider vinegar and whisk until fully combined. Set aside for 10 minutes to curdle. This creates a vegan ‘buttermilk’.
  3. In a large mixing bowl, sift the flour, cocoa powder, sugar, baking powder and bicarbonate of soda. Mix well to combine. Add the oil and a drop of red food gel into the ‘buttermilk’ and whisk to combine.
  4. Add the wet ingredients into the dry ingredients and mix just to combine. 
  5. Spoon the batter into the lined tin. Level it out with the back of a spoon or offset spatula.
  6. Place the cake into the middle of the preheated oven and bake for around 25-30 minutes. You will know it is done when you put a knife or skewer down the centre of the cake and it comes out clean and it’s springy to the touch. If batter comes off on the skewer, it needs more time to bake. To prevent burning, top the cake with some greaseproof paper then return back into the oven.
  7. Allow the cake to cool in the tin for 10 minutes then carefully transfer onto a cooling rack. Allow to cool fully before frosting. You can even place the cake in a sealed container once cool then frost the day after. It’s a very light sponge so be careful with it when removing from the tin.

Method (frosting)

  1. In a large mixing bowl, add in the dairy-free butter and cream cheese, whip until creamy. I use a stand mixer with a balloon whisk attachment, a hand mixer will work great too.
  2. Sift in the icing sugar and vanilla. Whip on high speed for a couple of minutes to incorporate it. Add a splash of dairy-free milk to get it to a smooth consistency. 
  3. Remove 4 heaped tablespoons of the buttercream and separate into a separate bowl. Leave the majority of the buttercream white, colour the smaller bowl with some pink food gel. You don’t need much coloured frosting for this, only for the love hearts on top, so only use what you need. The rest of the frosting can be swirled to the top of the cake.
  4. Transfer the pink buttercream into a piping bag fitted with a star tip nozzle.
  5. Pipe heart shapes over the top of the cake. Finish with some vegan sprinkles (optional).
  6. Cut into squares, serve and enjoy! 


To store: This cake uses cream cheese frosting, so store in a sealed container in the fridge. Leave at room temperature for 15-20 minutes before serving. Best eaten within 2 days of making. Un-iced cake can be stored in a sealed container at room temperature for 2 days. 

What food colour to use? Gels are highly pigmented which means you won’t need as much. I like to use THIS brand of food gels.
