Brownie Batter:

  • 100 g dark chocolate
  • 200 g caster sugar
  • Zest from 1 large orange
  • 140 g plain flour
  • 20 g cocoa powder
  • 1 teaspoon baking powder
  • 80 ml vegetable oil
  • 240 ml plant milk
  • 1 teaspoon orange extract
  • 100 g vegan chocolate chips/chunks (optional)

Chocolate Orange Buttercream:

  • 75 g vegan butter softened
  • 150 g icing sugar sifted
  • 1/4 teaspoon orange extract
  • 75 g vegan chocolate
  • 2 tablespoons vegan cream or plant milk


Make The Brownie Batter:

  • Preheat oven to 180°C / 160°C Fan / 350°F / Gas Mark 4. Line a 20cm square cake tin with parchment paper and set aside.
  • Break the dark chocolate up and add to a small heatproof bowl set over a pan of simmering water (bain-marie) - make sure the base of the bowl is not directly touching the water. Gently melt the dark chocolate until it’s smooth.
  • In a large mixing bowl, mix the sugar and orange zest together. Now sift together the flour, cocoa powder and baking powder. Give these ingredients a quick whisk together to combine then whisk in the oil, plant milk and orange extract until you have a smooth batter. Whisk in the melted chocolate until incorporated. Finally, if using fold through the extra chocolate chips/chunks.
  • Transfer the brownie batter to the lined tin.
  • Bake the brownies for 25-30 minutes - I always bake mine for 25 minutes because I like the brownies extra fudgy. Leave to cool completely in the tin before cutting in to 16 squares. We left ours overnight before cutting.

Make The Buttercream:

  • Cream the butter and icing sugar for about 2 minutes until light and fluffy. Add the orange extract, melted chocolate and vegan cream and mix until combined. Spread the buttercream over the top of the brownie or slice the brownie up and pipe the buttercream on top.
  • The brownies will keep stored in an airtight container at room temperature for up to one week.
