Ingredients
- 175g unsalted butter, softened, plus extra for the tin
- 85g caster sugar
- 85g soft light brown sugar
- 3 eggs
- 175g self-raising flour
- 2 tbsp instant espresso powder
- 2 tbsp boiling water
- 100g unsalted butter, softened, for frosting
- 200g icing sugar
- 1 tsp instant espresso powder
- 1 tsp boiling water
- ½ tsp vanilla extract
- Extra espresso powder for dusting
Instructions
- Begin by preheating your oven to 180°C (160°C fan/Gas Mark 4) to ensure it’s perfectly ready for baking.
- Carefully butter a 900g loaf tin, then line it with baking paper, making sure to leave some paper overhanging for easy removal later.
- In a small bowl, dissolve 2 tablespoons of instant espresso powder in 2 tablespoons of boiling water, then set it aside to cool completely. This concentrated coffee will infuse your cake with incredible flavor.
- In a large mixing bowl, beat together the softened unsalted butter, caster sugar, and soft light brown sugar until the mixture becomes wonderfully pale, light, and delightfully fluffy.
- Introduce the eggs into the mixture one at a time, incorporating a spoonful of flour with each addition to prevent curdling and maintain a smooth batter.
- Once all the eggs are in, gently beat in the remaining self-raising flour along with the completely cooled coffee mixture until your batter is smooth and well combined.
- Carefully transfer the rich, aromatic batter into your prepared loaf tin, using a spatula to smooth the top evenly.
- Bake the loaf cake for approximately 40–45 minutes, or until a skewer inserted into the very center of the cake comes out perfectly clean, indicating it’s thoroughly baked.
- Allow the freshly baked cake to cool down completely on a wire rack before even thinking about adding the frosting – patience is key for perfect frosting!
- Now, for the luscious frosting: in a clean bowl, beat the softened unsalted butter for about 1 minute until it’s light and creamy.
- Gradually add the icing sugar, beating well after each addition until it’s fully incorporated and smooth.
- Finally, stir in the cooled espresso mixture and vanilla extract, then continue to beat until your latte frosting is wonderfully smooth, creamy, and ready to spread.
- Generously spread the dreamy latte frosting over the top of your completely cooled coffee loaf cake.
- For an elegant finishing touch, dust the cake lightly with a sprinkle of extra espresso powder just before you serve it.
Serving and Storage Tips
- For the absolute best texture and to truly savor every nuanced flavor, make sure to serve this delightful cake at room temperature.
- Elevate your treat by pairing each slice with your favorite hot coffee, a rich espresso, a comforting cup of tea, or simply a refreshing glass of cold milk.
- It’s crucial to let the cake cool completely before you even think about adding the frosting; this prevents any dreaded melting and ensures a beautiful finish.
- To keep your frosted cake fresh and delicious, store it in an airtight container at room temperature for up to 2 days.

- Before frosting a frozen cake, ensure it’s completely thawed to room temperature for the best results.

FAQs
**1. Can I substitute regular instant coffee for espresso powder in this recipe?**
Absolutely, you can! While instant coffee will work, remember that espresso powder is specifically chosen for its ability to deliver a more intense, richer coffee flavor that truly shines in this cake. If you’re looking for that deep coffeehouse taste, stick with the espresso powder.
**2. Is it possible to make this delicious cake without any frosting?**
Yes, indeed! The loaf itself is incredibly moist and packed with enough flavor to be thoroughly enjoyed plain. Alternatively, a simple dusting of icing sugar can provide a lovely, understated sweetness.
**3. My coffee cake tastes a bit weak – what went wrong?**
To ensure a robust coffee flavor, it’s vital that your espresso powder is sufficiently concentrated. If you prefer an even bolder coffee kick, don’t hesitate to add a little extra espresso powder to the batter next time.
**4. Can I use salted butter if that’s all I have on hand?**
While unsalted butter is generally preferred for baking as it gives you precise control over the overall saltiness and flavor profile, you can certainly use salted butter. Just be mindful of the added salt when considering other seasonings in your recipe.
**5. How do I know for sure when my loaf cake is perfectly baked?**
The foolproof method is to insert a clean skewer or toothpick right into the center of the cake. When it comes out clean, or with just a few moist crumbs clinging to it, your cake is ready!

**6. Oh no, my cake sank in the middle! What caused this?**
A sunken cake often indicates it was either underbaked and removed from the oven too soon, or the oven door was opened prematurely during the baking process, causing a sudden temperature drop. Ensure the center is fully set and baked before taking it out.
**7. Can I prepare this delightful cake in advance?**
Absolutely! This cake is perfect for making ahead. You can bake the loaf a day before, keep it well covered, and then apply the frosting shortly before you plan to serve it for ultimate freshness.
**8. Is it possible to freeze this Coffee Loaf Cake for later enjoyment?**
Yes, it freezes beautifully! The unfrosted cake is particularly well-suited for freezing when it’s tightly wrapped in plastic, then foil, and stored in an airtight freezer-safe container.
**9. What if I want to use only brown sugar instead of a mix?**
While you certainly can use all brown sugar, utilizing both caster and brown sugar in the recipe creates a delightful balance of sweetness, contributes to the cake’s lovely moisture, and imparts a nuanced caramel flavor that truly enhances the overall taste.
**10. What are some ideal accompaniments for Coffee Loaf Cake?**
This cake is incredibly versatile! It pairs exquisitely with a piping hot coffee, a rich espresso, a frothy cappuccino, a soothing cup of tea, or even a generous scoop of creamy vanilla ice cream for a decadent dessert experience.
Ultimately, this Coffee Loaf Cake stands out as a truly satisfying and incredibly easy baking project for any coffee enthusiast.
