How to Make Mary Berry Butterscotch Traybake

  1. Preheat the oven to 180°C (160°C fan/Gas Mark 4). Grease the tin and line it with baking parchment to stop the cake from sticking.
  2. Prepare the traybake tin before mixing the batter. Place the self-raising flour, baking powder, softened butter, light soft brown sugar, eggs, and milk into a large bowl.
  3. Use the all-in-one method and beat everything together until the mixture becomes light, smooth, and well combined. Scrape down the sides of the bowl if needed to make sure everything is evenly mixed.
  4. Fold in the butterscotch chips using a spatula. Pour the batter into the prepared tin and level the surface with the back of a spoon.
  5. Bake on the centre shelf for 30–35 minutes. The cake is ready when it is golden, springs back lightly when touched, and a skewer comes out clean.
  6. Leave the cake in the tin for a few minutes before transferring it to a wire rack. Allow it to cool completely before making the icing.
  7. Melt the butter in a small saucepan over gentle heat. Add the light brown soft sugar and stir until the sugar has dissolved, then remove from the heat and stir in the double cream.
  8. Gradually beat in the sifted icing sugar until the icing is smooth. Pour the warm icing over the cooled cake and spread it evenly with a palette knife.
  9. Let the icing set before cutting the traybake into squares. Serve once the topping is firm enough to slice neatly.

Expert Tips for Mary Berry Butterscotch Traybake Recipe

A few simple techniques can make a noticeable difference when baking this traybake. I have found that careful mixing, accurate baking time, and patience while icing help create a softer sponge and a smoother finish with a rich butterscotch flavour.

  • Use room temperature ingredients so the batter mixes evenly and bakes into a moist cake.
  • Do not overmix the batter after everything is combined, as this can make the sponge less light and fluffy.
  • Check the cake a few minutes before the suggested baking time to avoid overbaking.
  • Make sure the brown sugar dissolves completely before adding the icing sugar to prevent a grainy icing.
  • Allow the cake to cool completely before icing, otherwise the topping may become too runny.
  • Spread the icing evenly while it is still warm for a smooth, professional-looking finish.
  • If making the cake ahead, store the unfrosted cake in an airtight container and add the icing on the day you plan to serve it.
  • For the best caramelized flavour, use good-quality light brown sugar and butterscotch chips.
