Ingredients Needed for Mary Berry Chocolate Cake With Oil Recipe

For the Cake

• 200g plain flour
• 200g caster sugar
• 75g cocoa powder (unsweetened)
• 1.5 tsp baking powder
• 1.5 tsp bicarbonate of soda
• 2 eggs
• 250ml whole milk
• 125ml vegetable oil (or sunflower oil)
• 1 tsp vanilla extract
• 250ml boiling water

For the Chocolate Frosting

• 100g dark chocolate (melted)
• 50g butter
• 2 tbsp cocoa powder
• 200g icing sugar
• 2–3 tbsp milk (to loosen)

Instructions: Step-by-Step Method

Step 1: Prepare Your Oven and Tin

Preheat oven to 180°C (160°C fan)/350°F. Grease and line two 8-inch round cake tins.

Step 2: Mix Dry Ingredients

In a large mixing bowl, sift together flour, sugar, cocoa powder, baking powder, and bicarbonate of soda.

Step 3: Combine Wet Ingredients

In another bowl, whisk eggs, milk, oil, and vanilla extract until smooth.

Step 4: Mix and Add Water

Gradually mix the wet ingredients into the dry ingredients. Slowly add the boiling water while whisking. The batter will be thin, but that’s what creates a moist cake.

Step 5: Bake

Divide the batter evenly between the prepared tins. Bake for 25–30 minutes or until a skewer comes out clean. Let cool in the tins for 10 minutes, then transfer to a wire rack.

Step 6: Make the Frosting

Melt the chocolate and butter together. Add cocoa powder, icing sugar, and a little milk to loosen it into a spreadable consistency.

Step 7: Assemble and Decorate

Spread frosting between the layers and over the top and sides. Decorate with grated chocolate or berries for a finishing touch.
