  • 140 g dark chocolate (broken into pieces) (5oz.)
  • 50 g unsalted butter (1/4 cup)
  • 50 g brown sugar (1/4 cup)
  • 1 egg
  • 35 g all-purpose flour (1/4 cup)

Butter cake:

  • 120 g unsalted butter (1/2 cup)
  • 100 g sugar (I reduced by 1 tbsp) (1/2 cup)
  • 2 eggs
  • 120 g all-purpose flour (1 cup)
  • 2 g baking powder (1/4 tsp)
  • 50 ml fresh milk (3 1/2 Tbsp)


  1. Grease and line a 10cm x 20cm (4x8-in) loaf pan with aluminium foil.
  2. Preheat oven to 180C/350F.
  3. To make brownie, melt chocolate and butter over low heat. Remove and leave to cool slightly. Stir in brown sugar until blended.
  4. Add in egg, mix well. Fold in flour, mix until well combined. Pour batter into prepared pan. Bake in preheated oven for 15 minutes. Remove.
  5. To make butter cake, beat butter with sugar until creamy. Add in eggs, one at a time, beating well after each addition.
  6. Fold in sifted flour and baking powder, alternately add in fresh milk, mix to form batter.
  7. Spread the butter cake batter over brownie, bake in oven at 160C/320F for 25-30 minutes or until cooked. Insert a cake tester in the middle to check doneness.

Recipe Notes

I am using conversion chart. For the best results, please follow the metrics measurement. I mixed the butter cake batter while baking the brownie. Then I poured the butter cake batter VERY QUICKLY onto the "hot" brownie. The butter cake batter will melt instantly. The second time I baked this brownie butter cake, I put the butter cake batter into a piping bag and cut a big hole at the tip, pipe in the butter cake batter quickly, and  just shake and tap the pan to smooth the top.
