Best Chocolate Cake

Here is a simple, moist chocolate cake recipe adapted for a halogen oven, with UK-style quantities and steps. All timing and temperature are guidelines; check your own oven the first time you make it.​

Ingredients

For a 7–8 inch (18–20 cm) round tin:

  • 115 g soft butter
  • 175 g caster sugar
  • 175 g self-raising flour
  • 2 tablespoons cocoa powder
  • 1 heaped teaspoon baking powder
  • 2 large eggs
  • 4 tablespoons milk (more if batter is very thick)
  • 1 teaspoon vanilla extract (optional)

Buttercream (optional):

  • 75 g soft butter
  • 150 g icing sugar
  • 2 tablespoons cocoa powder
  • 1–2 tablespoons milk, to loosen

Equipment and tin prep

  • Use a metal cake tin that fits easily inside the halogen oven on the low or middle rack; 18–20 cm is ideal.​
  • Grease the tin and line the base with baking paper so the cake releases cleanly.

Mixing the cake

  1. Beat margarine/butter and caster sugar together until pale and fluffy. This traps air and helps the cake rise well.​
  2. Beat in the eggs one at a time, adding a spoonful of flour if the mixture looks like it might curdle.
  3. Sift together self-raising flour, cocoa, and baking powder, then fold gently into the wet mixture.​
  4. Stir in milk (and vanilla, if using) until the batter drops slowly but easily off a spoon; it should be soft but not runny.
  5. Scrape into the prepared tin and level the top. Leave a little space to allow the cake to rise.

Baking in a halogen oven

Halogen ovens run a little hot and the top element is close to the cake, so use a slightly lower temperature and keep an eye on browning.​

  1. Preheat the halogen oven to about 160–170 °C on the low or middle rack for a few minutes.​​
  2. Place the filled tin on the rack; if your oven tends to brown the top quickly, lay a loose circle of foil over the tin (not touching the batter). This protects the surface while the centre cooks.​
  3. Bake for about 20–30 minutes before first checking; smaller, shallower tins will be closer to 20 minutes, deeper cakes nearer 30.​
  4. Check doneness by inserting a skewer in the centre; it should come out clean or with a few moist crumbs, and the top should spring back when lightly pressed.​
  5. If the middle is still wet but the top is brown, cover loosely with foil and continue baking in 3–5 minute increments until done.
  6. Cool in the tin for 10 minutes, then turn out onto a rack and let it cool completely before icing.

Simple chocolate buttercream

  1. Beat the soft butter until smooth.
  2. Sift in icing sugar and cocoa, then beat together, adding milk a teaspoon at a time until smooth and spreadable.
  3. Spread over the cooled cake; you can just top it, or fill and cover the sides if you slice the cake in half horizontally.​
