This toffee apple cake is a tender, golden sponge layered with soft, cinnamon-spiced apple pieces and finished with a smooth, amber toffee sauce that sets to a gentle, sticky glaze on top. It carries the warmth of baked fruit and brown sugar throughout, with a crumb that holds its moisture beautifully from the apples folded into the batter. This version is designed for a straightforward bake, needing no specialist equipment and delivering consistent results every time. It suits everything from a Sunday afternoon tea to a casual dinner party pudding served warm. From start to finish, the cake is ready in around 1 hour 20 minutes.

How to Make Mary Berry Toffee Apple Cake Recipe

Prepare the tin and oven: Heat the oven to 180°C (160°C fan, Gas 4). Grease a deep 20cm round cake tin and line the base and sides with baking parchment. Lining the sides as well as the base prevents the edges from over-baking before the centre sets.
Coat the apple pieces: Toss the cubed apple with the tablespoon of light brown sugar and half teaspoon of cinnamon in a small bowl until evenly coated. Set aside while you make the batter.
Cream the butter and sugar: Beat the softened butter and muscovado sugar together in a large bowl using a hand-held electric mixer for 4 to 5 minutes, until the mixture is noticeably lighter in colour and has a fluffy, almost mousse-like consistency.
Add the eggs: Beat in the eggs one at a time, adding a tablespoon of flour with each addition. This prevents the mixture from curdling, keeping the batter smooth and even throughout.
Fold in the dry ingredients: Sift the remaining flour, baking powder, cinnamon, and nutmeg over the batter. Fold everything together gently with a large metal spoon until just combined. Add the milk and fold again until the batter falls easily from the spoon.
Incorporate the apple pieces: Reserve about a quarter of the spiced apple for the top of the cake, then fold the remainder gently into the batter. Avoid over-mixing at this stage so the apple pieces keep some of their shape during baking.
Fill and top the tin: Spoon the batter into the prepared tin and smooth the surface level with a palette knife or the back of a spoon. Scatter the reserved apple pieces across the top, pressing them in very lightly.
Bake the cake: Place on the middle shelf of the oven and bake for 45 to 55 minutes, until the top is a deep, even golden brown and a skewer inserted into the centre comes out clean. If the top starts to colour too quickly after 35 minutes, lay a loose piece of foil over it.
Make the toffee sauce: While the cake cools in the tin for 10 minutes, melt the butter in a small saucepan over a medium-low heat. Add the muscovado sugar and stir until dissolved, then pour in the double cream and vanilla extract. Let the sauce bubble gently for 3 minutes, stirring occasionally, until it thickens slightly and takes on a deep amber colour. Remove from the heat and stir in the pinch of salt.
Finish and glaze: Turn the cake out onto a wire rack set over a tray. Spoon the warm toffee sauce slowly over the top, allowing it to run down the sides in places. Scatter over the chopped walnuts and a pinch of flaky sea salt while the glaze is still tacky.

Tips for the Best Toffee Apple Cake

Why does my toffee apple cake sink in the middle after baking?

This usually happens when the oven door is opened too early, causing a sudden drop in temperature before the sponge structure has set. Wait until at least 40 minutes have passed before checking the cake, and use the skewer test to confirm it is fully baked through.

Why does the toffee sauce turn grainy instead of smooth?

Grainy toffee sauce is caused by sugar crystals forming when the mixture is stirred too vigorously while the sugar is dissolving. Stir gently and keep the heat at medium-low until the sugar is fully dissolved before the cream goes in.

How do I stop the apple pieces from sinking to the bottom of the cake?

Tossing the apple cubes in sugar and cinnamon before folding them in gives their surface a light coating that helps them stay suspended in the batter. Cutting the pieces to roughly 1cm is also important; larger chunks are heavier and more likely to drop.

Why is the crumb of my cake dense rather than light?

Over-folding once the flour is added develops too much gluten and knocks out the air beaten into the butter and sugar. Fold only until no dry flour is visible, stopping even if the batter looks slightly uneven.

Why does my toffee sauce stay too runny and not set on the cake?

The sauce needs to bubble on the heat for a full 3 minutes to thicken properly. If it still seems very loose, return it to the hob for another minute or two, then spoon it over the cake while it is warm but not boiling hot.

Serving Suggestions

Serve warm with a jug of thick double cream poured at the table for a relaxed afternoon tea.
Pair with a scoop of good-quality vanilla ice cream for a dinner party pudding; the contrast between cold cream and warm toffee is part of the appeal.
Slice and serve at room temperature alongside a strong Assam or Darjeeling tea for a mid-morning treat.
Warm individual slices briefly in the microwave for 20 to 30 seconds and finish with an extra drizzle of the reserved toffee sauce if you have made a larger batch.
Dust lightly with icing sugar just before serving if the toffee glaze has been absorbed into the sponge while storing.

Storage

Room Temperature

Store the cooled cake in an airtight tin or container at room temperature for up to 2 days.

Refrigerator

Wrap the cake tightly in cling film or place it in a lidded container and refrigerate for up to 5 days. Remove from the fridge at least 30 minutes before serving to allow the sponge to return to a soft, tender texture.

Freezing

Freeze individual slices, wrapped first in cling film and then in foil, for up to 3 months. Defrost overnight at room temperature and warm gently in a low oven at 150°C (130°C fan) for 8 to 10 minutes before serving.

FAQs

Can I use eating apples instead of Bramley apples in this recipe?

Yes, Cox or Granny Smith apples work well as they hold their shape during baking rather than turning to purée as Bramleys sometimes do. The flavour will be slightly sweeter and less tart, so the overall cake will taste a little milder.

Can I make this toffee apple cake ahead of time?

The sponge can be baked a day in advance and stored in an airtight container. Make the toffee sauce fresh on the day of serving and pour it over the cake just before bringing it to the table for the best glossy finish.

Can I use salted butter instead of unsalted in the sponge?

Salted butter can be used in both the sponge and the sauce. If you do, simply leave out the pinch of salt in the toffee sauce and omit any additional salt from the topping to avoid the finished cake tasting over-seasoned.

What size tin works best for this toffee apple cake?

A deep 20cm round tin gives the best results, producing a cake with enough height to show the apple pieces throughout the layers. A shallower tin will cause the batter to spread and bake too quickly, resulting in a drier texture.

Can I leave out the walnuts if there is a nut allergy?

The walnuts are entirely optional and can be left out with no effect on the bake. A small amount of pumpkin seeds or a few thin apple slices pressed gently on top before baking make a neat nut-free alternative for the finishing touch.
