One Bowl Chocolate Olive Oil Cake

This rich and indulgent One Bowl Chocolate Olive Oil Cake has a texture to die for! It’s sophisticated yet so easy to make—you could practically bake it blindfolded (though we don’t recommend it). The olive oil adds an incredible truffle-like texture, while buttermilk gives it that all-important tang. Trust me, it’s a total winner!

Serves: 6 | Prep Time: 15 mins | Cook Time: 35 mins | Total Time: 50 mins

Ingredients

  • 3 medium eggs

  • 150g caster sugar

  • 70g soft brown sugar

  • 80ml extra virgin olive oil (mild in flavour)

  • 150g 70% or 85% dark chocolate

  • 110g ground almonds (or 90g spelt flour)

  • 1/3 tsp baking powder

  • 1/4 tsp bicarbonate of soda

  • 1/3 tsp sea salt

  • 100ml buttermilk

  • 1 tsp vanilla extract

  • Cocoa powder for dusting

  • Mascarpone for serving

Method

  1. Preheat the oven to 170°C (fan). Grease a 9-inch baking tray.

  2. Melt the chocolate using a bain-marie (a bowl over simmering water). Stir until smooth and set aside to cool slightly.

  3. Whisk together eggs, sugars, and olive oil in a large bowl until just combined, achieving a double cream-like consistency.

  4. Add the dry ingredients: Stir in the ground almonds, salt, and sieve in the bicarbonate of soda and baking powder.

  5. Add the melted chocolate: Mix in the cooled melted chocolate, followed by the vanilla extract and buttermilk. Be careful not to over-mix—about 10 seconds should do!

  6. Bake: Pour the mixture into the prepared tin and place it in the oven. Bake for about 35 minutes, or until a skin has formed on top and the cake begins to pull away slightly from the edges. A skewer inserted should come out slightly sticky.

  7. Cool and serve: Let the cake cool completely before removing it from the tin. Dust generously with cocoa powder and serve with whipped mascarpone.

Enjoy this decadent chocolate cake as a sweet treat for any occasion. It keeps for up to 4 days covered, making it perfect for prepping ahead!
