Step‑by‑Step Instructions for Coffee and Walnut Cake
Step 1: Preheat Your Oven
Begin by preheating your oven to 180°C (350°F). While it warms up, prepare two 8-inch round cake pans by greasing them generously with butter and lightly dusting with flour, or lining them with parchment paper. This ensures your Coffee and Walnut Cake will release easily after baking.
Step 2: Prepare the Coffee Mixture
In a heatproof bowl, combine the instant coffee granules with boiling water, stirring until completely dissolved. Allow the mixture to cool to room temperature; this step is crucial for maintaining the integrity of the eggs later in the process. Once cooled, you’ll have a rich coffee foundation for your cake.
Step 3: Mix the Dry Ingredients
Sift together the all-purpose flour, baking powder, and salt in a large mixing bowl. This helps evenly distribute the leavening agent and creates a lighter texture. Set aside this bowl as you gather the remaining ingredients for your Coffee and Walnut Cake, ensuring everything is well-measured and ready to go.
Step 4: Cream Butter and Sugar
In another bowl, beat the softened unsalted butter and granulated sugar together using an electric mixer on medium speed. Continue mixing for about 3-5 minutes, or until the mixture is light, fluffy, and pale in color. This aeration is critical for a moist cake and will give your Coffee and Walnut Cake a lovely texture.
Step 5: Incorporate the Eggs
Add the eggs to the butter-sugar mixture one at a time, mixing well after each addition. Do this for about 1-2 minutes per egg until fully incorporated. The mixture should remain fluffy and well-blended, ensuring your cake has the right structure before moving on to the next ingredients.
Step 6: Blend in Coffee and Vanilla
Now, gently stir in the cooled coffee mixture along with the vanilla extract until fully combined. This rich amalgamation adds a deep coffee flavor to your batter. Mix carefully, making sure not to overbeat at this stage, which could affect the texture of your Coffee and Walnut Cake.
Step 7: Combine Mixtures
Gradually add the sifted dry ingredients to the wet mixture, alternating with the whole milk. Begin and end with the flour mixture, mixing on low speed until just combined and smooth. This method ensures your Cake batter is well-blended without sacrificing the airy quality essential for your Coffee and Walnut Cake.
Step 8: Fold in Walnuts
Carefully fold the chopped walnuts into the batter using a spatula. This gentle folding incorporates the nuts without deflating the batter. Aim for an even distribution throughout the batter, as these walnut bits will provide a lovely crunch and nutty flavor that complements the coffee beautifully.
Step 9: Divide and Bake
Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula, and place them in the preheated oven. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should rise and develop a golden-brown color, signaling their readiness.
Step 10: Cool the Cakes
Once baked, remove the pans from the oven and let them cool in the pans for 20 minutes. After this, carefully transfer the cakes onto a wire rack to cool completely. This step is crucial before frosting, allowing the layers to set properly for your Coffee and Walnut Cake.
Step 11: Prepare the Frosting
For the frosting, in a clean bowl, beat the softened unsalted butter with an electric mixer. Gradually add the powdered sugar, mixing on low speed, until incorporated. Pour in the brewed coffee and beat until the frosting is creamy and smooth. This flavorful frosting will perfectly complement the cake layers.
Step 12: Assemble the Cake
Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of frosting between the layers, then place the second layer on top. Use the remaining frosting to cover the top and sides of the cake, creating an inviting finish for your Coffee and Walnut Cake.
Step 13: Garnish
For an elegant touch, top your frosted Coffee and Walnut Cake with additional chopped walnuts. This not only adds visual appeal but also emphasizes the lovely walnut flavor. Now your gorgeous creation is ready to serve, promising to delight everyone at the table!

Expert Tips for Coffee and Walnut Cake

Room Temperature Ingredients: Ensure all ingredients are at room temperature for optimal mixing and a smoother batter for your Coffee and Walnut Cake.
-
No Overmixing: Avoid overmixing after adding dry ingredients; this can lead to a dense texture instead of the airy delight you’re aiming for.

Coffee and Walnut Cake Recipe FAQs
How do I choose the right walnuts for my cake?
Absolutely! When selecting walnuts, look for nuts that are firm and don’t have dark spots or shriveled appearances. Fresh walnuts will have a pleasant, nutty aroma. If you see any signs of mold or strange smells, it’s best to pass on those. For a different twist, consider chopped pecans; they can offer a similar crunch with a slightly sweeter taste.
What’s the best way to store leftover Coffee and Walnut Cake?
Very! Store your leftover cake in an airtight container at room temperature for up to 3 days. If you want to keep it for a longer duration, place it in the refrigerator, and it will stay fresh for up to a week. However, make sure that the container is sealed well to maintain its moisture.
Can I freeze my Coffee and Walnut Cake?
Definitely! To freeze, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. This method ensures that each slice maintains its moist texture. Your cake can be frozen for up to 3 months. When you’re ready to enjoy it, simply thaw it overnight in the refrigerator, or warm the slices in the microwave for a delightful treat.
What should I do if my cake falls flat or is dense?
If your cake isn’t rising or comes out dense, it’s often due to overmixing after adding the dry ingredients. Mix until just combined for best results! Additionally, make sure your baking powder is fresh and properly measured. If you’ve baked at a low temperature, ensure your oven is accurate; an oven thermometer can help with this!
Is this Coffee and Walnut Cake safe for people with nut allergies?
Not at all! This cake contains walnuts, making it unsuitable for anyone with nut allergies. For a nut-free version, you could experiment with adding chocolate chips for a new flavor dimension, or simply omit the nuts altogether. Always check for nut-free ingredients, especially in your frosting.
Can I substitute the eggs in this recipe?
For sure! If you’re looking for an egg substitute, aquafaba (the liquid from a can of chickpeas) is a fantastic option—3 tablespoons of aquafaba replace one egg. Just whip it a bit before mixing it into the batter, and you’ll achieve a similar texture that helps bind your Coffee and Walnut Cake beautifully!
