Step‑by‑Step Instructions for Mary Berry Coffee Fudge Traybake
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (160°C fan) or 350°F. While the oven warms, grease and line a 9×9-inch traybake tin with parchment paper, allowing some overhang for easy removal later. This sets the stage for your Mary Berry Coffee Fudge Traybake and ensures the batter won’t stick.
Step 2: Mix Butter and Sugar
In a large mixing bowl, add softened butter and light brown sugar, then beat together using an electric mixer for about 5 minutes until the mixture is pale and fluffy. This step is crucial as it introduces air into the batter, giving your traybake a light and airy texture that every bite deserves.
Step 3: Incorporate Eggs
Gradually add the eggs to the butter and sugar mixture, beating well after each addition to achieve a smooth consistency. This should take about 2 minutes. It’s important to mix thoroughly after each egg to ensure that the mixture doesn’t curdle, making it ready for the next step.
Step 4: Fold in Dry Ingredients
Sift the self-raising flour and baking powder into the mixing bowl. Gently fold these dry ingredients into the wet mixture using a spatula or wooden spoon until just combined. Be careful not to overmix, as this could lead to a dense cake instead of the fluffy Mary Berry Coffee Fudge Traybake you want.
Step 5: Add Coffee and Walnuts
Dissolve the instant coffee granules in a small amount of hot water, then stir this into your batter along with chopped walnuts, if you’re using them. This step infuses your sponge with delightful coffee flavor and adds an appealing crunch. Make sure everything is evenly distributed without overworking the batter.
Step 6: Bake the Traybake
Pour the batter into your prepared traybake tin and smooth the top with a spatula. Place it in the preheated oven and bake for 25-30 minutes. Your cake is ready when it turns golden brown and springs back when lightly pressed in the center. Use a skewer to check for doneness—as it should come out clean.
Step 7: Cool in the Tin
Once baked, remove the traybake from the oven and let it cool completely in the tin. This cooling step helps the flavors develop and makes the cake easier to slice. Patience is key here; allow it to rest undisturbed for about 30 minutes to an hour for the best results.
Step 8: Prepare the Icing
In a mixing bowl, beat softened butter with icing sugar until light and fluffy, which should take about 3-4 minutes. Gradually mix in the dissolved coffee to achieve the desired flavor profile. If the icing is too thick, add a splash of milk to adjust it to a spreadable consistency.
Step 9: Ice the Traybake
Once the cake has cooled completely, use a spatula to spread the coffee icing evenly over the top. Take your time to ensure a smooth, even layer that glistens invitingly under the light. If desired, decorate with walnut halves on top for an extra touch of elegance.

How to Store and Freeze Mary Berry Coffee Fudge Traybake
Room Temperature: Store the traybake in an airtight container at room temperature for up to 4 days to maintain its delightful texture and moisture.
Fridge: If you prefer a firmer icing, the traybake can also be refrigerated for up to a week. Just remember to keep it in an airtight container to prevent drying out.
Freezer: The un-iced Mary Berry Coffee Fudge Traybake can be frozen for up to 3 months. Wrap it tightly in plastic wrap or foil, then place it in a freezer bag for best results.
Thawing: To enjoy later, thaw the frozen traybake in the fridge overnight and apply the icing before serving for a fresh taste!

Expert Tips for Mary Berry Coffee Fudge Traybake
-
Butter at Room Temperature: Ensure your butter is fully softened for easy mixing, which leads to a lighter sponge. Hard butter may create lumps and affect texture.
-
Mind the Mixing: Avoid overmixing when folding in the dry ingredients. Too much mixing can lead to a dense cake instead of the fluffy Mary Berry Coffee Fudge Traybake you desire.
-
Test for Doneness: Use a skewer to check if the traybake is done; it should come out clean or with only a few crumbs. Undercooked batter can ruin the cake’s texture.
-
Cool Completely: Allow your cake to cool completely in the tin before icing. This helps the flavors meld and ensures the icing doesn’t melt into the sponge.
-
Sift Icing Sugar: Always sift your icing sugar before mixing it with butter. This prevents lumps and ensures a smooth, creamy coffee fudge icing that’s visually appealing.
