- Salt – Enhances flavors; do not omit this crucial ingredient.

Step‑by‑Step Instructions for Coffee and Walnut Cake
Step 1: Preheat the Oven and Prepare Pans
Begin by preheating your oven to 180°C (350°F). While it heats up, take two 8-inch round cake pans and grease them with butter or non-stick spray. Then, line the bottoms with parchment paper to prevent sticking. This initial step ensures your Coffee and Walnut Cake will bake evenly and release beautifully when you’re ready to serve.
Step 2: Dissolve Coffee
In a bowl, pour boiling water over the instant coffee granules and stir until fully dissolved. Allow this mixture to cool at room temperature, which will enhance the coffee’s rich flavor without cooking the batter. This step is essential for achieving that perfect balance of coffee essence in your cake.
Step 3: Combine Dry Ingredients
Sift together all-purpose flour, baking powder, and salt into a large mixing bowl. This process aerates the flour and helps prevent lumps, leading to a lighter texture in your cake. Set the bowl aside and get ready to mix your wet ingredients next, ensuring all your dry ingredients are evenly combined for the best results.
Step 4: Cream Butter and Sugar
In a separate bowl, use a hand mixer or stand mixer to cream the softened unsalted butter and granulated sugar together on medium speed until the mixture turns light and fluffy, about 3-5 minutes. This step is crucial for incorporating air, which helps your Coffee and Walnut Cake rise beautifully while giving it that decadent texture.
Step 5: Incorporate Eggs
One by one, add the eggs to the butter and sugar mixture, mixing well after each addition until fully combined. The eggs act as a binding agent, creating a rich and moist structure in your cake. Beat until the mixture is pale and fluffy, ensuring a light and airy batter for your cake.
Step 6: Blend Wet Ingredients
Pour in the cooled coffee mixture and the vanilla extract, mixing gently until everything is combined. This step brings the coffee flavor to the forefront, ensuring that each bite of your Cake is infused with that aromatic essence. Take care not to overmix, as you want to maintain the light texture you’ve created.
Step 7: Mix Dry and Wet Ingredients
Gradually add the dry mixture to the butter mixture, alternating with the whole milk. Start and finish with the dry mixture, mixing just until smooth. This method helps maintain that wonderful balance of moisture and structure in your Coffee and Walnut Cake, so don’t overmix!
Step 8: Fold in Walnuts
Gently fold in the chopped walnuts using a spatula, being careful to incorporate them without losing the fluffiness of the batter. The walnuts not only add crunch but also a delightful nuttiness that pairs perfectly with the coffee flavor. This gives your cake that quintessential taste and texture.
Step 9: Transfer to Pans and Bake
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula. Place them in the oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Keep an eye on your cakes; they should be golden brown and spring back when lightly pressed.
Step 10: Cool the Cakes
Once baked, remove the Cake from the oven and let the pans cool on a wire rack for about 20 minutes. Then, carefully turn them out of the pans and peel off the parchment paper. Allow the cakes to cool completely on the wire rack before frosting to prevent melting.
Step 11: Prepare the Frosting
In a bowl, beat the softened butter until creamy, then gradually add the powdered sugar, mixing on low speed. Once combined, pour in the brewed coffee and mix until smooth. The frosting should be light and spreadable, ready for adorning your Coffee and Walnut Cake with a luscious layer of rich flavor!
Step 12: Assemble the Cake
Place one layer of the cooled cake on a serving plate. Frost the top with a generous layer of frosting, then add the second layer on top. Finish by frosting the top and sides of the cake to achieve a beautiful finish. Take a moment to admire your creation—it’s nearly time to dig in!
Step 13: Garnish
For a lovely finishing touch, sprinkle additional chopped walnuts on top of the frosted cake. This not only adds visual appeal but also enhances the texture with an extra crunch. Now your Ultimate Coffee and Walnut Cake is ready to impress at any gathering or cozy moment!

Expert Tips for Coffee and Walnut Cake
-
Use Softened Butter: Make sure your butter is at room temperature for easy creaming; this helps achieve a fluffy texture in your Coffee and Walnut Cake.
-
Cool the Coffee Mix: Allow the dissolved coffee to cool before adding it to the batter; hot coffee can affect the batter’s integrity and make the cake dense.

Check Fresh Ingredients: Ensure your baking powder is fresh for proper leavening. An expired product can lead to a cake that fails to rise.

Coffee and Walnut Cake Recipe FAQs
How do I choose ripe walnuts for the recipe?
Absolutely! When selecting walnuts, look for whole nuts that are firm and free of dark spots or blemishes. Fresh walnuts should smell nutty and pleasant, not rancid. If possible, choose those packaged in clear containers, allowing you to inspect them for freshness.
What is the best way to store leftover Coffee and Walnut Cake?
You can store your leftover Coffee and Walnut Cake in an airtight container at room temperature for up to 3 days. If you’ve frosted the cake, it’s best to refrigerate it, where it will stay fresh for about a week. Just ensure it’s well-covered to prevent drying out.
Can I freeze the Coffee and Walnut Cake?
Very! To freeze your cake, first, allow it to cool completely. Wrap slices tightly in plastic wrap, and then place them in a freezer-safe container. This method helps prevent freezer burn. The Cake can be frozen for up to 3 months. When you’re ready to enjoy a slice, thaw it in the fridge overnight and let it come to room temperature before serving!
What if my Coffee and Walnut Cake is too dense?
If your cake turns out denser than expected, it may be due to overmixing the batter or using too much flour. To prevent this next time, try lightly folding in the dry ingredients and avoid packing the flour when measuring. Remember, a light hand makes for a wonderfully airy cake!
Is this recipe suitable for those with nut allergies?
It’s generally not suitable for individuals with nut allergies since it contains walnuts. If you’re seeking a nut-free alternative, you can substitute the walnuts with seeds like sunflower or pumpkin seeds for texture, or simply enjoy the cake as is without nuts for a smooth coffee flavor.
What’s the best way to know when my cake is done baking?
You’ll want to give your cake a gentle poke or use a toothpick—insert it into the center of the cake, and if it comes out clean or with a few moist crumbs, your Cake is ready. Timing is everything, so keep an eye on it after 25 minutes to ensure it doesn’t overbake!
