Ingredient Highlight
Below is the full ingredient list, presented in the order they’re used. Understanding each component helps you tweak the recipe to suit dietary needs or flavor preferences.
- 250 g butter, softened (+ extra for greasing) – Provides a tender crumb and a buttery aroma.
- 250 g self‑raising flour – The built‑in leavening keeps the cake light without an extra baking soda/powder step.
- 1 tsp baking powder – Adds a little extra lift, ensuring the traybake rises evenly.
- 225 g drinking chocolate powder – Gives a deep cocoa flavor without the expense of couverture chocolate.
- 250 g light soft brown sugar – Contributes moisture, caramel notes, and a gentle sweetness that balances the tart berries.
- 4 eggs, lightly beaten – Bind the batter and add richness.
- 3 tbsp milk – Helps achieve a smooth, pourable consistency.
- 200 g frozen berries (raspberries, blackberries, blueberries) – Provide bursts of juiciness; they also keep the batter cool, preventing over‑mixing.
- 200 g white chocolate, broken up – Melted for the decorative drizzle; adds a creamy contrast to the dark chocolate base.
- Fresh raspberries – Used for final garnish; they add a pop of color and fresh flavor.
- Small pink marshmallows – Fun, kid‑friendly topping that adds a chewy texture.
- Candles – The finishing touch for birthday celebrations.
Pro Tips for Each Ingredient
| Ingredient | Tip |
|---|---|
| Butter | Let it sit at room temperature for 30 min before creaming; this yields a fluffier batter. |
| Self‑raising flour | Sift with the cocoa powder and baking powder to avoid lumps and ensure even distribution. |
| Drinking chocolate powder | If you prefer a richer chocolate taste, substitute half of the powder with unsweetened cocoa and increase the sugar by 20 g. |
| Frozen berries | No need to thaw; they’ll melt into the batter while baking, creating pockets of juicy sauce. |
| White chocolate | Use a double boiler (or a heat‑proof bowl over simmering water) to melt gently—this prevents scorching and keeps the glaze glossy. |
| Marshmallows | Cut larger marshmallows in half for a balanced look, or use mini marshmallows for a speckled effect. |

Step‑by‑Step Instructions
Follow these numbered steps for a flawless Chocolate and Berry Traybake. Each instruction is derived directly from the original method array, reformatted for clarity.
- Preheat & Prepare the Tin
- Set the oven to 180 °C (fan 160 °C / gas mark 4).
- Grease and line a 30 cm × 20 cm cake tin with parchment paper.
- In a large bowl, sift together the self‑raising flour, baking powder, and drinking chocolate powder.
- Cream Butter & Sugar, Then Incorporate Eggs
- In a separate bowl, cream the softened butter with the light soft brown sugar until the mixture is pale and fluffy (about 3–4 minutes with a hand mixer).
- Gradually add the lightly beaten eggs, beating well after each addition to maintain a smooth texture.
- Combine Wet and Dry Ingredients
- Add the flour‑cocoa mixture to the butter‑egg mixture, followed by 3 tbsp milk.
- Gently fold everything together until just combined—over‑mixing can make the cake dense.
- Add Berries & Bake
- Spoon the batter into the prepared tin, spreading it evenly.
- Poke the frozen berries into the surface, spacing them out so each bite gets a burst of fruit.
- Bake for 45 minutes, covering the cake with a double layer of baking paper halfway through to prevent over‑browning.
- The cake is done when it has risen, a skewer inserted into the centre comes out clean, and the surface bounces back lightly when pressed.
- Cool the Cake
- Allow the traybake to cool in the tin for a few minutes, then turn it out onto a wire rack to cool completely. This prevents the bottom from becoming soggy.
- Prepare the White‑Chocolate Drizzle
- Place the broken white chocolate in a heat‑proof bowl.
- Set the bowl over a pan of gently simmering water (double boiler).
- Stir occasionally until the chocolate is smooth and fully melted, then remove the bowl from the heat.
- Decorate
- Using a teaspoon, drizzle the melted white chocolate across the cake in random lines or a decorative pattern.
- Arrange fresh raspberries, pink marshmallows, and candles on top for a festive look.
- Serve & Enjoy
- Let the glaze set for a few minutes, then slice the traybake into generous portions.
- Pair with a glass of cold milk, a scoop of vanilla ice cream, or a dollop of whipped cream for extra indulgence.

Serving Suggestions & Variations
Classic Celebration Presentation
- Birthday Mode – Place a candle in the centre of each slice, or arrange a row of candles along one edge for a “birthday cake” vibe.
- Kids’ Party – Use colorful sprinkles or edible glitter on the white‑chocolate drizzle for extra visual appeal.
Flavor Twists
| Variation | How to Implement |
|---|---|
| Citrus Zest | Add the zest of one orange or lemon to the batter for a bright, aromatic lift. |
| Nutty Crunch | Fold in ½ cup of toasted chopped almonds or hazelnuts before baking. |
| Coffee Boost | Replace 1 tbsp of milk with 1 tbsp strong brewed espresso for a mocha twist. |
| White‑Chocolate Berry | Swap the drinking chocolate powder for 150 g melted dark chocolate and increase the white‑chocolate drizzle for a marbled effect. |
| Vegan Adaptation | Use plant‑based butter, a flax‑egg substitute (1 tbsp ground flax + 3 tbsp water per egg), and dairy‑free white chocolate. |
Pairings & Accompaniments
- Dairy Pairing – A scoop of vanilla bean ice cream or a dollop of lightly sweetened mascarpone balances the richness.
- Fruit Side – Serve with a fresh mixed‑berry compote (fresh raspberries, strawberries, and a splash of orange liqueur).
- Beverage Match – Cold milk for kids, or a glass of semi‑dry Riesling or sparkling rosé for adults.
Storage Tips
- Room Temperature – Covered with a cake dome, the traybake stays fresh for 2–3 days.
- Refrigeration – If you need to keep it longer, store in an airtight container in the fridge for up to 5 days; bring to room temperature before serving for optimal texture.
- Freezing – Slice and wrap individual portions in cling film, then place in a freezer bag. They freeze well for up to 2 months. Thaw overnight in the fridge and let sit at room temperature before serving.
