The Malt Sponge:

- 1 tsp Baking Powder: Extra insurance for a fluffy rise.
- 225g (8 oz) Caster Sugar: Fine sugar for a tender crumb.
- 4 Large Eggs: Beaten.
- 2 tbsp Malt Extract Powder: (Like Ovaltine or Horlicks). This gives the signature malty taste.
The Malted Icing:
- 100g (3 ½ oz) Butter: Softened.
- 200g (7 oz) Icing Sugar: Sifted.
- 2 tbsp Malt Extract Powder: For flavor.

How To Make Mary Berry Malt Chocolate Cake
- Prep the Tins: Preheat the oven to 180°C (160°C Fan / Gas 4). Grease two 20cm (8in) sandwich tins and line the bases with baking parchment.
- Make the Cocoa Paste: In a small bowl, mix the cocoa powder with the hot water until you have a smooth, thick paste. Let it cool slightly.
- All-in-One Method: Place the baking spread, flour, baking powder, sugar, eggs, and malt powder into a large mixing bowl. Add the cocoa paste. Using an electric mixer, beat everything together for about 2 minutes until smooth and well-blended. Avoid overbeating.
- Bake: Divide the batter evenly between the two prepared tins. Level the tops. Bake for 25–30 minutes until the cakes are well-risen and shrinking slightly from the sides of the tins.
- Cool: Leave the cakes in the tins for 5 minutes, then turn them out onto a wire rack. Remove the parchment paper and let them cool completely.
- Whip the Buttercream: Measure the butter into a bowl and beat until pale and soft. Add the icing sugar, malt powder, and cocoa powder. Mix carefully at first (to avoid a sugar cloud), then beat vigorously. Add the milk gradually until you reach a creamy, spreadable consistency.
- Assemble: Place one cake layer on a serving plate. Spread with half of the buttercream. Top with the second cake layer. Spread the remaining buttercream over the top (swirling it with a palette knife).
- Decorate: Arrange the Maltesers in a ring around the edge or pile them in the center. Serve.

Recipe Tips
- Malt Powder Choice: Horlicks or Ovaltine work best. Avoid “light” versions if possible, as they have less malt flavor. If you really love malt, add an extra tablespoon to the icing.
- Cocoa Paste: Mixing the cocoa with hot water “blooms” the flavor, releasing more chocolate notes than dry powder alone. It also prevents the sponge from being dry.
- Buttercream Texture: If the icing feels gritty from the malt powder, add a tiny splash more milk and beat for an extra minute to help dissolve the granules.
- Storage: Maltesers can become soft and chewy if left on the cake in an airtight container overnight. For the best crunch, add them just before serving.
What To Serve With Malt Chocolate Cake
- Cold Milk: The malt flavors scream for a glass of ice-cold milk.
- Vanilla Ice Cream: A classic scoop pairs perfectly.
- Strawberries: Fresh fruit cuts through the milky sweetness.
- Coffee: A flat white complements the creamy malt notes.

How To Store Malt Chocolate Cake
- Room Temperature: Store the cake in an airtight tin for up to 3 days.
- Refrigerate: In hot weather, chill the cake to keep the buttercream firm, but bring to room temp before eating for the best sponge texture.
- Freeze: Freeze the sponge layers (unfilled) for up to 3 months. The assembled cake can be frozen, but the Maltesers will lose their texture.

FAQs
Can I use melted chocolate instead of cocoa?
You can, but it changes the texture to a denser, fudgier cake. This recipe relies on cocoa for a light, airy sponge that matches the malt lightness.
Can I make cupcakes?
Yes. Divide the batter into 12-14 cupcake cases and bake for 15-20 minutes. Top with a swirl of malt icing and a single Malteser.
Is this the same as the u0022Traybakeu0022 version?
Mary has a traybake version too. The ingredients are similar, but this sandwich cake version allows for a thicker layer of filling, which is where the malt flavor really shines.
