Ingredients You’ll Need
Getting the perfect Vegan Coffee Walnut Cake Recipe starts with a handful of straightforward ingredients that work harmoniously to build incredible texture, flavor, and aroma. Each item here plays a crucial role, whether it’s the espresso infusing depth or the walnuts adding that essential crunch.
- Walnuts (finely chopped): Adds a lovely nutty crunch and earthy flavor that balances the sweetness.
- All-purpose flour (sifted): The foundation of the cake’s soft yet sturdy structure.
- Soft brown sugar: Provides caramel-y sweetness and moisture that’s essential in vegan baking.
- Baking powder: Leavens the cake to make it light and fluffy.
- Baking soda: Works with the acidity in the vegan buttermilk for a tender crumb.
- Sea salt: Enhances all the flavors and balances the sweetness.
- Espresso or strong coffee (cooled): Infuses the cake with that signature coffee flavor you’ll adore.
- Vegan buttermilk: Offers subtle acidity and moisture, perfect for keeping the cake tender.
- Olive oil or neutral oil: Keeps the texture moist without overpowering any flavors.
- Vanilla extract: Adds a sweet, floral note that harmonizes beautifully with coffee and walnuts.
- Walnut halves (for candied walnuts): Provide a stunning crunchy topping that’s irresistibly caramelized.
- Soft brown or granulated sugar (for candied walnuts): Sweetens and crisps up the walnut topping.
- Vegan butter or olive oil (for candied walnuts): Ensures the walnuts caramelize evenly without burning.
How to Make Vegan Coffee Walnut Cake Recipe
Step 1: Prepare Your Kitchen and Bakeware
First things first, preheat your oven to 160°C fan or around 180°C conventional. Prepare two cake tins by lining the bases with parchment paper and greasing the sides well. Having these ready upfront saves you stress later and ensures a smooth baking process.
Step 2: Combine the Dry Ingredients
In a large bowl, whisk together the finely chopped walnuts, sifted flour, soft brown sugar, baking powder, baking soda, and sea salt. Mixing these well now sets the foundation for the perfect crumb and ensures even distribution of all key flavors.
Step 3: Mix the Wet Ingredients
In a separate bowl, whisk your espresso (or cooled strong coffee), vegan buttermilk, olive oil, and vanilla extract. This wet mix combines the richness and acidity that will make your cake moist and flavorful.
Step 4: Create the Batter
Pour the wet ingredients into the dry and whisk gently, just until no flour pockets remain. Over-mixing is the enemy here — we want a light, tender crumb, so mix carefully to keep things airy.
Step 5: Bake the Cake
Divide the batter evenly between your prepared tins and pop them in the oven for 35 to 45 minutes. You’ll know they’re done when a toothpick inserted in the center comes out clean. Patience is key — no peeking too often!
Step 6: Cool Before Decorating
Once baked, let the cakes cool in their tins for 10 to 15 minutes. Then, carefully transfer them to a wire rack to cool completely. Cooling fully ensures your frosting won’t melt and your layers stay neat.
Step 7: Prepare the Candied Walnuts
While your cake cools, it’s time to make those addictive candied walnuts. Gently cook walnut halves with sugar and vegan butter or oil over low heat, tossing constantly until they’re golden and glossy. Keep some halves whole for topping, and chop the rest for the filling and finishing touches.
Step 8: Assemble with Vegan Coffee Buttercream
Layer your cake by spreading about a third of the vegan coffee buttercream on the first layer, then sprinkle with half the chopped candied walnuts. Top with the second cake layer and coat the entire cake with more frosting. Finish off by piping the remaining buttercream on top, adorning with whole candied walnuts and the remaining chopped walnuts for that professional, irresistible look.
How to Serve Vegan Coffee Walnut Cake Recipe
Garnishes
The candied walnut halves on top not only add crunch but elevate the appearance to bakery-worthy perfection. Consider lightly dusting the cake with cocoa powder or a few coffee beans to highlight the coffee theme even more.
Side Dishes
This cake pairs beautifully with simple sides like a scoop of vegan vanilla ice cream or a dollop of coconut whip. A hot cup of black coffee or creamy oat milk latte will also complement the cake’s robust coffee and walnut flavors delightfully.
Creative Ways to Present
For an extra-special occasion, serve small slices on vintage ceramic plates with an edible flower and a drizzle of vegan caramel sauce. Alternatively, cut the cake into bars for a casual party or gifting — they’re portable and still packed with flavor.
Make Ahead and Storage
Storing Leftovers
Your Vegan Coffee Walnut Cake Recipe keeps well in the fridge for up to 4-5 days. Store it in an airtight container to prevent the cake from drying out and to keep the frosting fresh. Remember to take it out about an hour before serving to soften it back up for that perfect slice.
Freezing
This cake is freezer-friendly! Wrap leftover slices or the whole cake tightly in plastic wrap and foil before freezing. When you’re ready to enjoy, thaw overnight in the refrigerator, then bring to room temperature for a few hours before serving.
Reheating
If you prefer your cake a bit warmed, gently microwave individual slices for 15 to 20 seconds or warm in a low oven with foil loosely covering the top to avoid melting the frosting. Warmed slightly, the coffee and walnut flavors really bloom.
FAQs
Can I use regular coffee instead of espresso in this Vegan Coffee Walnut Cake Recipe?
Absolutely! Just be sure to brew a strong coffee so the cake retains its signature rich coffee flavor. A lighter brew might give a subtler taste, but the cake will still be delicious.
Is it necessary to sift the flour for this cake?
While not mandatory, sifting your flour helps remove lumps and aerates it for a lighter crumb. It’s a little step that can noticeably improve the texture of your cake.
Can I substitute olive oil with another oil?
Yes, you can use neutral oils like sunflower or rapeseed oil if you prefer a less pronounced flavor than olive oil. Either will keep your cake moist and tender.
How do I make vegan buttermilk for this recipe?
Making vegan buttermilk is simple! Just add 1 tablespoon of lemon juice or apple cider vinegar to 240ml of plant-based milk, stir, and let sit for 5-10 minutes until it curdles slightly. This acidity helps with leavening and tenderness.
Can I make this cake nut-free by substituting walnuts?
While walnuts are a star ingredient here, you could try using chopped seeds like pumpkin or sunflower seeds for crunch. Keep in mind the flavor and texture will change, but it’s a good option for those with nut allergies.

Instructions
- Measure Ingredients: For accuracy, use a digital kitchen scale to weigh all ingredients precisely.
- Prepare Pans: Preheat your oven to 160°C/320°F fan or 180°C/356°F conventional. Line the base of two cake tins with parchment paper circles and grease the sides liberally with oil or vegan butter to prevent sticking.
- Mix Dry Ingredients: In a large bowl, whisk together the finely chopped walnuts, sifted flour, soft brown sugar, baking powder, baking soda, and sea salt until evenly combined.
- Mix Wet Ingredients: In a separate medium bowl, whisk espresso, vegan buttermilk, olive oil, and vanilla extract thoroughly until well blended.
- Make Batter: Gradually pour the wet ingredients into the dry ingredients and whisk gently until no visible flour pockets remain, taking care not to over-mix to maintain cake tenderness.
- Bake Cakes: Divide the batter evenly between the prepared cake tins. Bake for 35-45 minutes or until a toothpick inserted into the center comes out clean.
- Cool Cakes: Allow cakes to cool in the pans for 10-15 minutes, then transfer to a cooling rack to cool completely. Once cool, refrigerate in an airtight container until ready for assembly.
- Prepare Buttercream: Meanwhile, make the vegan coffee Swiss meringue buttercream according to your recipe or instructions.
- Candied Walnuts: In a pan over gentle heat, combine walnut halves, sugar, and vegan butter or oil. Cook for 5-7 minutes, tossing constantly until sugar melts and walnuts are fragrant. Remove from heat and cool on parchment paper. Reserve 16 walnut halves for decoration and chop the rest for filling and topping.
- Assemble Cake: Spread one-third of the coffee buttercream evenly over the first cake layer using an offset spatula. Sprinkle half of the chopped candied walnuts on top.
- Add Second Layer and Frost: Place the second cake layer atop the first. Coat the sides and top of the cake with another one-third of the frosting, smoothing evenly.
- Decorate: Pipe the remaining frosting over the top layer of the cake. Decorate with reserved candied walnut halves and sprinkle the remaining chopped walnuts over the top.
- Storage: Store the cake in an airtight container in the fridge for up to 4-5 days. Remove about an hour before serving to allow the frosting and cake to soften. Leftover cake can be frozen in airtight containers for future enjoyment.
