Step-by-Step Guide to Making Mary Berry Butterscotch Traybake

• Prepare the tray – Line a traybake tin with parchment and preheat the oven to 180°C (350°F).
• Start the sponge mixture – Beat 225g butter and 225g light brown sugar until pale and creamy.
• Add the eggs – Mix in the 4 eggs, one at a time, beating well after each.
• Incorporate dry ingredients – Fold in 225g self-raising flour, baking powder, and vanilla extract until smooth.
• Transfer and level – Pour the batter into the lined tin and spread evenly with a spatula.
• Bake the sponge – Bake for 25–30 minutes, or until golden and springy to the touch.

What I Got Wrong (And How I Fixed It)

• Icing set too quickly – Worked faster and added a splash of milk for looser consistency.
• Cake turned dry – Reduced baking time and checked early for doneness.
• Sponge too dense – Ensured butter and sugar were properly creamed for extra lightness.
• Icing grainy – Lowered the heat when melting sugar to avoid crystallisation.

FAQs

Why is my butterscotch traybake dry instead of soft and moist?

A dry sponge usually comes from overbaking or measuring too much flour. Bake only until the cake springs back when touched, and spoon-and-level the flour to avoid packing too much into the cup. Adding a teaspoon of milk to the batter can also help maintain moisture.

Why did my butterscotch icing turn grainy?

Grainy icing forms when the sugar isn’t fully dissolved before adding the icing sugar. Simmer the butter, brown sugar, and milk gently until the mixture becomes smooth and glossy. Removing from heat too early can cause crystallisation.

How do I stop the icing from setting before I spread it?

Butterscotch icing sets quickly as it cools. Work with the cake ready and spread immediately after whisking. If it thickens, warm it gently on low heat to loosen it again.

Can I make the traybake ahead of time without it drying out?

Yes—this traybake stores very well. Keep it in an airtight container at room temperature for up to four days. You can also freeze the un-iced sponge and add the icing after thawing for best texture.
