One-Bowl Chocolate Fudge Cake

What you need

This one-bowl chocolate fudge cake mixes in minutes and bakes into a deeply moist crumb with cocoa richness in every bite. Top with a quick chocolate ganache or simple buttercream when you need a reliable birthday or weeknight cake.

For the cake:

  • 200g (1½ cups) plain / all-purpose flour
  • 200g (1 cup) granulated sugar
  • 75g (¾ cup) unsweetened cocoa powder
  • 1½ tsp baking powder
  • 1½ tsp baking soda
  • 1 tsp fine salt
  • 2 large eggs
  • 240ml (1 cup) whole milk
  • 120ml (½ cup) neutral oil
  • 2 tsp vanilla extract
  • 240ml (1 cup) hot coffee or hot water

For the quick ganache (optional):

  • 150g dark chocolate, chopped
  • 120ml (½ cup) double / heavy cream

Recipe Steps

  1. Heat the oven to 175°C / 350°F. Grease and line two 20 cm (8 in) round tins (or one 23×33 cm / 9×13 in tin).
  2. In a large bowl whisk flour, sugar, cocoa, baking powder, baking soda, and salt. Whisk in eggs, milk, oil, and vanilla until smooth.
  3. Pour in the hot coffee and whisk — the batter will be thin. Divide between tins.
  4. Bake 30–35 minutes (or 35–40 for a sheet) until a toothpick comes out with a few moist crumbs. Cool 10 minutes, then turn out.
  5. For ganache, heat cream until steaming, pour over chocolate, wait 1 minute, then stir until glossy. Cool slightly and spread over the cooled cake.

Tips & Variations

  • Hot coffee blooms the cocoa for a deeper chocolate flavour without tasting like coffee.
  • Do not overbake — pull when crumbs still cling to the tester.
  • Cake layers freeze well wrapped for up to 2 months.
