Essential Ingredients for Your Sponge

A great sponge begins with simple, well-measured ingredients you can trust. Use fresh staples and a clear routine to get the light, tender crumb this recipe needs.

Dry ingredients

In a large bowl sift 225g of self-raising flour with 1 teaspoon of baking powder. Add 225g of light brown sugar and mix to combine. Ensuring the flour is fresh matters because the baking powder inside gives the sponge its rise.

Wet ingredients

Beat together 225g of soft butter and 4 large eggs until pale and smooth. Use a large bowl so you can cream the butter and sugar thoroughly — this step shapes the texture of the sponge.

Tip: Measure flour and sugar accurately for a balanced batter. High-quality eggs and butter help recreate the signature tender crumb recommended by mary berry.

Ingredient Amount Purpose
Self-raising flour 225g Structure and rise (contains baking powder)
Light brown sugar 225g Sweetness and moisture for flavour
Butter 225g, soft Richness and tender crumb
Eggs 4 large Bind and add lift

Preparing Your Baking Tin and Oven

Take a few careful steps before you mix the batter — a properly prepared tin and a hot oven set the scene for success.

Preheat oven to 180°C (350°F) before you start mixing. Doing this means the baking begins immediately and helps the sponge rise evenly.

Line a 9×12 inch traybake tin with baking parchment. Make sure the parchment fits neatly into the corners so the cake lifts out easily once cooled.

Mary Berry stresses that a prepared tin avoids sticking and promotes an even bake across the whole surface. Set the oven temperature precisely for consistent, golden-brown results every time.

  • Preheat oven to 180°C (350°F) before mixing the batter.
  • Use a well-fitted sheet of parchment in the prepared tin.
  • Check the oven temperature with an oven thermometer if needed.

Step Why it matters Quick tip
Preheat oven to 180°C (350°F) Ensures immediate, even rising and correct bake time Turn oven on before you assemble ingredients
Line the 9×12 inch tin Prevents sticking and speeds removal after cooling Press parchment into corners for a smooth fit
Check temperature Consistent heat gives predictable colour and texture Use an oven thermometer for accuracy

Mixing the Perfect Batter

Start by building lightness into the batter — good aeration makes for a springy, tender cake.

Creaming Technique

In a large bowl, beat 225g of butter and 225g of light brown sugar for about 2 minutes until the mixture looks pale and creamy.

Tip: Use a stand mixer or a hand whisk on medium speed to trap air efficiently.

Add the 4 eggs one at a time, beating well after each addition. This step helps the texture stay light and even.

Use a spatula to scrape down the sides of the bowl frequently. That ensures all ingredients are worked into the batter and nothing is left clinging to the bowl.

  • Once the batter is smooth, pour it into your prepared tin.
  • Use a spatula to level the surface so the cake bakes evenly.
  • Be careful not to overmix after you add the flour — too much mixing will make a dense cake rather than a light sponge.

The creaming method is central to the mary berry approach because it traps tiny bubbles in the butter and sugar. Those bubbles expand in the oven and give the sponge its lift.

Baking to Golden Perfection

Aim for an even, golden colour and a sponge that feels springy when touched at the centre. Bake in the preheated oven for about 35–40 minutes, though some recipes call for an initial check at 25–30 minutes. Use the gentle press test — the cake should spring back in the centre when you touch it.

Look for a golden top and a slight shrink away from the edges of the tin. These signs show the bake is complete and that the crumb set correctly. Oven performance varies, so always test the centre before removing the traybake.

Once removed, let the tray cool slightly in the tin for a few minutes. Then lift using the lining paper and place the cake on a wire rack to cool completely. Removing the paper while still warm stops the edges from going soggy.

  • Bake your traybake for 25–30 minutes to check initial colour and texture, then continue to 35–40 minutes if needed.
  • A perfectly baked sponge will feel firm and springy — a hallmark of the mary berry approach.
  • Allow the cake to cool completely on a wire rack before icing or storing.
Check What to look for Action
25–30 minutes Golden colour, beginning to spring back Test centre; continue baking if soft
35–40 minutes Firm, springs back, edges pulling away Remove from oven and cool slightly in tin
Cooling Warm lift from tin, then cool completely Transfer to wire rack; remove lining paper while warm

Crafting the Smooth Butterscotch Icing

Finish matters: a silky icing gives the cake its signature shine and rich taste. Follow a few quick steps to make a glossy glaze that sets neatly on top.

Melting the Butter and Sugar

To make icing, gently heat 75g of butter, 100g of light brown sugar and 50–75ml of milk in a small saucepan. Stir until the mixture is melted and smooth.

Simmer for 1 minute so the sugar fully dissolves — this helps prevent grainy texture once the icing sugar is added.

Finishing the Glaze

Remove the pan from the heat and sift in 150g of icing sugar. Whisk briskly with a spoon or whisk until the mixture is glossy and lump-free. Add a splash of vanilla if you like.

When the cake is cool completely, use a spatula to spread the warm icing over the surface. Work quickly: the glaze sets fast as it cools.

“Use 75g of butter for a rich, buttery flavour that defines this classic icing.”

If the icing thickens too much, warm it very gently to loosen it again. If the cake is not allowed to traybake cool, the icing will sink in, so be sure the sponge is fully cooled first.

Stage What to do Why it matters
Heat butter & sugar 75g butter, 100g brown sugar, milk; melt and stir Creates smooth base for icing sugar
Simmer Gently for 1 minute Dissolves sugar and avoids graininess
Whisk in icing sugar 150g sifted; whisk until glossy Gives smooth, spreadable glaze
Spread on cake Use a spatula on the cake once cool completely Prevents the icing from soaking into the sponge

Tips for Achieving the Ideal Texture

A few careful checks during baking will help you get a soft, even crumb every time.

Handle the batter gently once the flour is folded in. Too much mixing tightens the gluten and makes the sponge dense.

Keep an eye on the oven and check the centre by pressing lightly. The cake should spring back and feel slightly firm.

  • Avoid overbaking: test early so the sponge stays light and moist.
  • If the edges brown too quickly, loosely tent the tin with foil to protect the cake from the heat of the oven.
  • Add a splash of milk to the batter if the sponge seems dry; it helps retain moisture.
  • Apply the icing while it is still pourable for a smooth, even finish across the traybake.
  • Use fresh baking powder and properly measured flour to secure a steady rise and airy crumb, as advised by Mary Berry.
  • Have the surface ready before you make the glaze so the icing does not set too fast.

“Press the centre gently — if it springs back, the bake is done.”

Centre Gives slight spring Remove from oven
Edges Browning fast Tent with foil
Icing Sets too fast Prepare surface first

Creative Variations to Try

A few simple swaps—sweet syrups, chopped nuts or chocolate—turn a plain bake into something special. These small changes keep the basic method but add new depth to flavour and texture.

Flavour Twists

Spicy ginger boost: Fold 4 pieces of chopped stem ginger and 2 tablespoons of ginger syrup into the batter for a lively, warming hit. You can also add 1 teaspoon of ground ginger from a jar for extra aroma.

Deeper, treacly notes: Replace part of the sugar with a tablespoon or two of treacle to give a rich, molasses-like flavour that pairs well with baking powder in the mix.

Chocolate and nuts: For a more indulgent slice, fold in 6 tablespoons of chocolate chips or add chopped pecans or walnuts for crunch and healthier fats.

  • Swap vanilla for almond extract and add a pinch of ground cinnamon for warmth.
  • Try toffee pieces or chopped stem for a sticky, fruity contrast to the icing.
  • Use a light hand with add-ins so the sponge stays soft and even.

Tip: Keep proportions similar to the original recipe so the balance of butter, self-raising flour and eggs remains correct. Little tweaks deliver big flavour without extra fuss.

Storing and Freezing Your Traybake

How you store and freeze the sponge determines its texture and the ease of later icing.

At room temperature, keep the cake in an airtight container for up to 4 days to retain a soft, light crumb. Store it in a cool, dry room away from direct sunlight so flavours stay fresh.

storing icing

If you plan to freeze, do so before adding the icing. Wrap the un-iced sponge tightly in cling film and foil to prevent freezer burn.

Frozen sponge can keep for up to 3 months. Thaw at room temperature before you finish with the icing and cut into neat squares.

“Avoid refrigerating the slice — cold air can dry out the sponge and make the icing less glossy.”

  • Keep whole or cut: wrap individual squares in parchment for quick snacks or lunchboxes.
  • Tin tip: remove the cake from the tin once cooled and wrap it to store better.
  • mary berry advice: do not chill the iced cake; room temperature is kinder to texture and shine.
Storage method Duration Best practice
Airtight container (room) Up to 4 days Keep in a cool, dry place out of direct sunlight
Freezer (un-iced sponge) Up to 3 months Wrap well; thaw at room temperature before icing
Individual squares 4 days (room) Wrap in parchment then place in container for easy serving

Conclusion

A reliably soft sponge and glossy icing make this treat a go-to for casual and special occasions.

Follow the simple steps and use quality ingredients to recreate this classic cake at home. Keep to the creaming method, check your oven temperature and finish with a smooth icing using sifted icing sugar for the best shine.

Whether you stick to the traditional mary berry recipe or tweak the flavours, this traybake rewards clear technique and modest effort. It suits teas, parties and lunchboxes, and freezes well if made ahead.

Enjoy the baking, share the slices, and take pride in a dependable recipe that brings warm, nostalgic flavour to any table.

FAQ

What size tin should I use for this traybake?

Use a loose‑bottom or lined rectangular tin about 23 x 33 cm (9 x 13 in) for an even bake and neat slices. Grease the tin lightly and line with baking parchment so the sponge lifts out easily.

Can I swap self‑raising flour for plain flour?

Yes. Substitute plain (all‑purpose) flour and add 2 tsp baking powder per 225 g (1 cup) of flour. Sift together to ensure even raising and a lighter crumb.

How do I know when the sponge is cooked?

The top should be golden and spring back when pressed lightly. Insert a skewer into the centre — it should come out with a few moist crumbs but not wet batter. Allow the traybake to cool in the tin for 10–15 minutes before transferring to a wire rack to cool completely.

What’s the best way to make the butterscotch icing smooth?

Gently melt butter and soft brown sugar together, stir until glossy, then beat in sieved icing sugar and a splash of milk. Warm ingredients and gradual mixing give a silky glaze; finish with a spatula while the icing is still slightly warm for an even top.

Can I add stem ginger or other flavours to the batter?

Absolutely. Finely chopped stem ginger or a teaspoon of ground ginger lift the flavour. You can also try a little treacle, vanilla extract or citrus zest for different twists—adjust sugar slightly if you add very sweet elements.

How long does this traybake keep and can it be frozen?

Store in an airtight tin at room temperature for up to 4 days. For longer storage, freeze uniced slices in a single layer on a baking sheet, then transfer to a sealed container or freezer bag for up to 2 months. Defrost fully before icing.

My sponge sank in the middle — what went wrong?

Common causes are under‑baking, opening the oven door too early, or over‑beating the mixture so it collapses. Check oven temperature with a thermometer and follow the recipe timing; bake until the centre is set and the edges pull away slightly from the tin.

Can I make the icing ahead and store it?

Yes. Keep the butterscotch icing in an airtight jar in the fridge for up to a week. Warm gently to loosen before spreading. If it thickens too much, add a little warm milk and whisk to reach spreadable consistency.

Is it possible to make this recipe dairy‑free?

You can replace butter with dairy‑free spread and use a plant‑based milk for the icing. Choose a vegan margarine with good baking performance and adjust sweetness to taste, as some alternatives have different flavour profiles.

How should I cut the traybake into neat squares?

Chill the iced traybake for 30–60 minutes to firm the glaze. Use a long, sharp knife wiped clean between cuts or a warmed metal spatula for clean edges. Mark guides on the parchment underneath before cutting to keep slices uniform.
