Ingredients
Fortunately, coffee walnut cake takes mostly pantry staples and few fancy ingredients. Let's talk about the most important ingredients in this traditional British cake.
- Camp Essence: This old fashioned flavoring is made from chicory root, which tastes like coffee and has a very distinctive flavor. You can purchase Camp essence (affiliate) online, as it's hard to find in shops in the States.
- Walnuts: Use English walnuts, not black walnuts. Chopped walnuts are folded into the cake batter, while walnut halves are used to decorate the top.
- Flour: Use all-purpose flour (plain flour in the UK) for this cake.
- Baking Powder: Be sure your baking powder hasn't expired! If it's more than three months old, throw it out and use a fresh package instead.
See recipe card for full information on ingredients and quantities.
Variations
- Espresso Powder: Dissolve 4 teaspoons (or up to 3 tablespoons) of espresso powder in 1-2 tablespoons of hot water. Use in place of the Camp essence in the cake. Add more dissolved espresso powder to taste for the buttercream.
- Vegan: Use softened vegan butter and vegan milk and coconut cream to replace the dairy products. Use a vegan egg replacer or 1 cup of unsweetened applesauce for the eggs. (If using applesauce, add an extra ½ teaspoon baking powder.)
- Gluten Free: Use your favorite measure-for-measure gluten free flour instead of the plain flour. Bob's Red Mill and King Arthur are good brands here in the States.
How to Make Coffee & Walnut Cake
Measure out all the batter ingredients, making sure the butter and eggs are at room temperature.
- Put all the batter ingredients in a bowl (except for the milk). (image 1)
- Beat on medium-low speed with the paddle attachment of a stand mixer until well blended. If the batter is too stiff, add the milk a little at a time. (image 2)
- Then, divide the batter between two pans and bake at 350°F for 18-20 minutes. A toothpick inserted into the center should come out clean. Let the cakes cool for 5 minutes in the pan, then take it out of the pan and let it cool completely on a wire rack. (image 3)
- Make the buttercream by beating the butter until smooth, then sift in the icing sugar. Add the Camp essence and cream to give it a spreadable consistency, then beat until fluffy. (image 4)
- Once the cakes have cooled, peel off the parchment and sandwich them with half of the icing. Spread the rest of the icing on top. Decorate with the walnut halves (and a cocoa powder stencil if you're feeling fancy). Try to have one walnut per slice: 10 to 12. (image 5)
- Enjoy this delicious coffee and walnut cake! Hopefully, you're as much in love with this recipe as my family is. It's one of my favorite cakes of all time with it's simple yet delightful flavors and elegant decoration. You'll be glad you made it! (image 6)
Recipe FAQs
It's a two-layer sponge cake flavored with coffee essence and walnuts. The sponge is spread with buttercream icing and decorated with walnut halves on top. This treat is very popular throughout the UK in grocery stores and as a birthday dessert.
Yes, you can. Dissolve 4 teaspoons of instant coffee in 1 tablespoon of hot water, then use in the batter and icing. Don't use brewed coffee or espresso, as they don't have a concentrated flavor.
However, if you want to be old fashioned, use Camp chicory and coffee essence to add flavor. It adds a beautiful hint of bitterness to cut the sweet icing, and has a rich flavor that pairs nicely with the walnut. This is what Mary Berry and other British bakers use in their recipes.
Chicory and coffee essence is a dark, coffee-flavored syrup commonly mixed with warm milk to make a quick drink in the U.K. Since it has such a strong flavor, this essence is perfect for adding to batters and icings to give them a rich, bittersweet flavor. It supposedly was introduced as a fast way of making coffee for the British military.
One two-layer slice contains 551 calories. It has 31g of fat and 67g of carbs per slice as well. If you are trying to count your calories, I'd definitely cut a smaller slice or save this dessert for special occasions. Another option is to make this recipe into a traybake; then the calories would be cut in half.
Mix 1 tablespoon Camp essence with 1 cup of hot or cold milk to create a delicious coffee drink. Mix into porridge for a unique flavor. Add a tablespoon or two to plain buttercream to create coffee buttercream.
Leftovers: As with most homemade cakes, it does taste best when eaten the same day it's made, but it will stay fresh at room temperature for up to 3 days after baking. Be sure to keep it sealed inside of an airtight container or tin to prevent it from drying out.
Freezing: It's easier to pre-slice the cake first, then seal the pieces in a plastic zip-top freezer bag or an airtight container. Freeze for up to 1 month.
Defrost: Defrost each slice individually in the microwave or defrost the all leftovers at room temperature on the counter in a sealed container so it doesn't dry out.

Easy Coffee and Walnut Cake Recipe
Ingredients
For the Cake
- 1 ¾ cup + 2 tablespoons all-purpose flour
- 1 cup unsalted butter, softened
- 1 cup + 2 tablespoons caster sugar
- 1 cup walnuts, chopped
- 4 large eggs, at room temperature
- 2 ½ teaspoons baking powder
- 2 tablespoons Camp essence
- 1 tablespoon whole milk
For the Icing & Decoration
- ½ cup unsalted butter, softened
- 2 ½ cups icing sugar, sifted
- 1 tablespoon heavy whipping cream
- 2 ½ teaspoons Camp essence
- 10-16 walnut halves, one for each slice
- 1 tablespoon unsweetened cocoa powder, for stencil (optional)
Instructions
Making the Cake
- Preheat the oven to 350°F (175°C). Lightly butter two 9-inch (22 cm) springform tins and line their bases with baking paper. If using cake strips, soak them in cold water for 10 minutes and fasten them around the tins.
- Crack the eggs into the bowl of a stand mixer, then add the flour, butter, sugar, baking powder, walnuts, and Camp essence.
- Blend on medium-low speed until well combined. The batter should hesitantly fall from a spoon when shaken. If it doesn't, gradually add the tablespoon of milk until it reaches the right consistency.
- Evenly divide the batter between the two pans and spread it to the edges.
- Bake at 350°F for 18-20 minutes, until a toothpick inserted into the center comes out clean.
- Let the cakes cool for 10 minutes, then take them out of the tins and let them cool completely on wire racks, about 1 hour.
Making the Buttercream
- Beat the butter in the bowl of a stand mixer until smooth. Sift the icing sugar into the butter and beat on medium speed until combined.
- Scrape down the sides of the bowl, then beat in the coffee essence and 2 teaspoons of heavy cream. Add additional cream as needed to give the icing a spreadable consistency. Taste and adjust the amount of essence as you desire.
- For an extra fluffy icing, turn the mixer onto medium high speed and beat for 1-2 minutes until the buttercream is fluffy and smooth.
Decorating the Cake
- Peel the baking paper off the cakes, then set aside the one with the nicest top.
- Place the other layer top side up on the serving plate and spread half of the icing on top. Put the other layer on top to create a sandwich, then spread the remaining icing on top.
- If desired, place a clean stencil on top and dust with cocoa powder to create a letter, picture, or pattern.
- Place the walnut halves around the edges. Slice and serve.

If you want to cook in one single layer, how long should I bake it for?
Emma
Hi Lesley, I haven't tried baked this cake in one layer, but I'd suggest using a 9x13-inch pan. Try baking it for 30 minutes, then check with a toothpick for doneness. Enjoy!

There’s no way you should put 2 1/2 teaspoons of baking powder in it - I used 1tsp and it rose perfectly well. The recipe instructions left out the addition of the baking powder too, it’s a good job I remembered it. The icing is lovely, fluffy and creamy, but the cake flavour itself is bland and the icing doesn’t make up for it. I’ve had much better coffee walnut cakes using Camp essence. I sometimes use a recipe with Golden Syrup replacing some of the sugar and I switched to this one because I ran out of Golden Syrup (which is hard to find in America). I wouldn’t use this recipe again if I’m honest.
Emma
I'm sorry you found this recipe bland, RB. You can always add more Camp essence to taste, especially in the icing. The reason I added that much baking powder was because many recipes use self-raising flour, which already contains baking powder, and this was the amount of baking powder equivalent to that in the self-raising. Thanks for the heads up about adding the baking powder in the instructions as well. Coffee walnut cake using golden syrup sounds delightful!
Beka
I made this recipe the weekend just gone for a little gathering with some friends and it didn’t disappoint. I can’t eat nuts so wasn’t able to give the full taste test, but my friends said it was one of the best cakes they’d eaten. You can even see by the texture of the cake that it’s going to be a good one! Thanks Savor the Flavour for this recipe, you made some friends I haven’t seen in ages very happy!
Emma
Thanks so much for your review, Beka! We're sorry that you couldn't try the cake, but we're thrilled that our recipe could bring so much joy to your friends.
Alex
The cake is soft and fluffy. The icing is bittersweet with the Camp essence, and the walnut on top is crunchy. I love the creamy icing and the soft cake. Mouthwatering!
Emma
Thank you, Alex! I’m so glad that you enjoyed this cake so much.
Brad
Wonderful cake. Mine came out a little dry. I do not think I over baked it. Any suggestions?
Emma
I'm so happy to hear that you enjoyed the cake, Brad! This is one of our family favorite cakes. 🙂
If the cake was dry, just make sure to measure the flour accurately next time. Weighing it on a kitchen scale ensures a correct measurement; it's easy to pack too much flour into a measuring cup. I'd also suggest calibrating your oven temperature; many ovens often bake too hot, which can dry out a cake.
Hope this helps! Happy baking. 🍰
Beth
The cake has the delicious aroma of Camp essence and walnuts. It is very fluffy and filled with walnut pieces. The buttercream is soft and yummy. This flavor combination is unusual but delicious. I love this amazing cake just as much as chocolate cake. The strong coffee ☕️ flavour is scrummy when matched with walnuts. Please try this recipe, you won't regret it!
Emma
Thank you, Beth! Coffee and walnut cake is definitely one of my favorites.
