Step‑by‑Step Instructions for Mary Berry Coffee Fudge Traybake
Step 1: Preheat and Prepare
Begin by preheating your oven to 180°C (160°C fan) or 350°F. While the oven warms up, grease and line a 9×9-inch baking tin with parchment paper. This ensures easy removal of your delicious Mary Berry Coffee Fudge Traybake once baked. A properly lined tin also helps the cake rise evenly.
Step 2: Cream Butter and Sugar
In a large mixing bowl, combine the softened butter and light brown sugar. Use an electric mixer on medium speed to cream them together until the mixture turns pale and fluffy, typically around 3-5 minutes. This step is crucial for incorporating air into the batter, resulting in a light and delightful sponge.
Step 3: Add Eggs
Next, add the eggs to the butter-sugar mixture, incorporating them one at a time. Beat well after each addition to achieve a smooth consistency. This process can take about 2-3 minutes. The eggs will help bind the ingredients, creating a rich, moist base for your Mary Berry Coffee Fudge Traybake.
Step 4: Incorporate Dry Ingredients
Sift in the self-raising flour and baking powder over the wet mixture. Using a spatula, gently fold the dry ingredients into the batter to maintain an airy texture. Be careful not to overmix, as this can lead to a dense sponge. You want the mixture to be just combined with no visible flour remaining.
Step 5: Mix in Coffee and Nuts
Dissolve the instant coffee granules in a small amount of hot water, then stir it into the batter along with chopped walnuts, if using. This step enhances the coffee flavor of your Traybake and adds delightful texture. Mix until fully incorporated, ensuring that the coffee is evenly distributed throughout the batter.
Step 6: Bake the Traybake
Pour the batter into the prepared baking tin, smoothing the top with a spatula to ensure even baking. Place it in the preheated oven and bake for 25-30 minutes. The cake is ready when it turns golden brown and springs back when gently pressed in the center—trust your senses!
Step 7: Cool Before Icing
Once baked, remove your Mary Berry Coffee Fudge Traybake from the oven and let it cool in the tin for about 10 minutes. Then, transfer it to a wire rack to cool completely. This is a crucial step; icing a warm cake can lead to a messy result, so patience is key!
Step 8: Prepare the Icing
While the cake cools, beat the softened butter and icing sugar together in a medium bowl until the mixture is light and creamy. This may take about 3-4 minutes. If the icing appears too thick, gradually add milk until it reaches a pourable but spreadable consistency, ready to adorn your traybake.
Step 9: Ice the Cake
Once your cake is completely cool, spread the prepared coffee icing evenly over the top, using a spatula for a smooth finish. This adds a luxurious and glossy layer to your Mary Berry Coffee Fudge Traybake. For an extra touch, consider decorating the top with walnut halves to enhance its visual appeal.
Step 10: Slice and Serve
After the icing has set slightly, slice the traybake into squares or rectangles according to your preference. Serve with a cup of freshly brewed coffee or tea, and enjoy the wonderful flavors of your indulgent creation. Each bite offers a delightful burst of coffee goodness that’s perfect for sharing!

Make Ahead Options
These Mary Berry Coffee Fudge Traybakes are a fantastic option for meal prep, ensuring you can enjoy a delicious treat with minimal fuss! You can prepare the batter and store it in the refrigerator for up to 24 hours before baking, which helps maintain its light and airy texture. Alternatively, bake the traybake and cool it completely, then wrap it tightly in plastic wrap to refrigerate for up to 3 days, or freeze uniced for up to 3 months. When ready to enjoy, simply thaw and ice it before slicing. This way, you’ll have a delectable coffee-infused dessert ready to impress with little effort, perfect for busy weeknights or surprise guests!

Cooling Properly: Allow the traybake to cool completely before icing. Icing too soon can cause it to melt and become runny, ruining the presentation.

Customize the Icing: If your icing is too thick for spreading, gradually add a bit of milk until you reach your desired consistency.

Mary Berry Coffee Fudge Traybake Recipe FAQs
What is the best way to select ripe ingredients for this traybake?

For instant coffee granules, select a high-quality brand to ensure that the coffee flavor shines through every bite.
How should I store my Mary Berry Coffee Fudge Traybake?
Store your traybake in an airtight container at room temperature for up to 4 days. This will help maintain its moisture and allow the flavors to deepen over time. Alternatively, refrigerate it for up to a week; just make sure it’s well covered to prevent drying out.

When you’re ready to enjoy it, thaw the traybake overnight in the fridge, and once it’s at room temperature, you can add the icing before serving.
What should I do if my sponge turns out dense?
Very commonly, a dense sponge could result from overmixing once you add the flour. To avoid this, mix the wet and dry ingredients just until they are combined—no more! Additionally, ensure your baking powder is fresh, as expired leavening agents won’t give the rise needed for a light texture.
Are there any dietary considerations for this recipe?
Absolutely! This recipe is vegetarian, but if you need to accommodate allergies or other dietary needs, consider omitting the walnuts for a nut-free version. For a dairy-free option, substitute the butter with margarine and use dairy-free milk for the icing. Always double-check ingredient labels to ensure they meet your dietary needs.
