Instructions

Preparation of Cake Batter

Begin by preheating your oven to 350°F (175°C). Prepare your cake pans by greasing them generously with butter or non-stick spray, then lightly dusting with flour or lining them with parchment paper to prevent sticking. Proper preparation of pans is crucial for easy removal and an even surface.

Dry Ingredient Mixture

In a large mixing bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. Sifting aerates the flour, removes lumps, and ensures even distribution of leavening agents. This step is fundamental for achieving a light, fluffy cake texture.

Wet Ingredient Mixture

In a separate bowl, using an electric mixer or a sturdy whisk, beat the softened butter and granulated sugar on medium speed until the mixture turns pale, fluffy, and increases in volume—this typically takes about 3-4 minutes. Proper creaming is essential for the cake’s tender crumb and good rise.

Incorporating Eggs and Coffee

One at a time, add the eggs to the creamed mixture, ensuring each is fully incorporated before adding the next. This prevents curdling and promotes an emulsion that traps air, aiding the rise. Dissolve the instant coffee powder in hot water and add to the mixture, blending thoroughly to distribute the coffee flavor evenly.

Combining Ingredients

Reduce mixer speed and alternately add the dry ingredients and sour cream to the wet mixture, beginning and ending with the dry. Add about one-third of the dry mixture, followed by half of the sour cream, and repeat until all are incorporated. Mix just until combined; over-mixing can result in a dense cake.

Folding in Walnuts

Using a spatula, gently fold in the chopped walnuts until evenly distributed. Folding preserves the air in the batter, contributing to a light and moist cake.

Baking the Cake Layers

Divide the batter equally between the prepared cake pans. Use a spatula or an off-set spatula to smooth the surface for even baking. Place the pans on the middle rack of the preheated oven and bake for 25-30 minutes. Check for doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs.

Cooling

Allow the cake layers to cool in the pans for about 10 minutes before transferring them to wire racks. Cooling on racks prevents condensation and sogginess. Wait until fully cooled before frosting to maintain clean, sharp layers and prevent melting of the frosting.

Preparing the Coffee Frosting

In a mixing bowl, beat the softened butter on medium speed until creamy and smooth. Gradually add the sifted powdered sugar, a cup at a time, beating well after each addition. Dissolve the instant coffee in hot water and add to the frosting along with vanilla extract. Continue beating until smooth, fluffy, and spreadable. Adjust consistency by adding a little milk or more powdered sugar if needed.

Assembling the Cake

Place one cooled cake layer on your serving plate. Spread an even layer of frosting over the top, smoothing it with an offset spatula. Carefully place the second layer on top, pressing gently to secure. Cover the top and sides of the cake with the remaining frosting, smoothing edges and creating a finished appearance. For a decorative touch, press additional chopped walnuts onto the sides or top of the cake.

Preparation Tips

• Ingredient Temperature: Ensure butter, eggs, and sour cream are at room temperature to facilitate better emulsification and a tender crumb.
• Coffee Flavor: Use high-quality instant coffee for a robust flavor. For a more intense coffee taste, you can brew strong coffee and reduce it to a concentrated syrup to incorporate into the batter.
• Walnut Preparation: Toast walnuts lightly before chopping to enhance their flavor and crunch.
• Layer Uniformity: Weigh batter portions or use a measuring cup for consistent layer thickness.
• Frosting Consistency: Chill the frosting slightly if it becomes too soft during application, especially in warm environments.

Nutritional Information

Tips and Tricks

• For a richer coffee flavor: Experiment with different coffee intensities—try espresso powder or cold brew concentrate for a more profound taste.
• Adding moisture: Incorporate a splash of coffee liqueur or milk into the frosting for extra depth and moisture.
• Decorative accents: Use cocoa powder, chocolate shavings, or edible gold leaf for an elegant finish.
• Layer stability: Chill the assembled cake for 30 minutes before frosting to help set the layers and improve handling.

Add-ons

• Chocolate chips or chunks mixed into the batter for a chocolate-coffee twist.
• Caramel or coffee-flavored syrup drizzled over the layers before frosting.
• Fresh fruit such as raspberries or cherries as garnish for added color and flavor.
• Whipped cream or mascarpone for a lighter frosting alternative.

Side Dishes

• Fresh fruit salad with berries and citrus for a refreshing contrast.
• Tea or coffee served alongside for a complete indulgent experience.
• Light vanilla or caramel ice cream to complement the cake.

Improvements

• Replace sour cream with Greek yogurt for added tang and protein.
• Use almond or hazelnut flour for a nutty variation.
• Incorporate a layer of coffee-flavored jelly or mousse for added texture.
• Add a splash of bourbon or amaretto to the frosting for an adult-only version.

Save and Store

Once assembled, store the Coffee Walnut Cake in an airtight container at room temperature for up to 24 hours or refrigerate for up to 3 days. To preserve moisture, cover loosely with plastic wrap or a cake dome. For longer storage, wrap individual slices in plastic wrap and freeze for up to 2 months. Thaw in the refrigerator overnight before serving. Bringing the cake to room temperature before slicing enhances flavor and texture.

FAQ

Can I make this cake gluten-free?

Yes, substitute all-purpose flour with a high-quality gluten-free baking blend. Ensure the blend contains xanthan gum or add it separately to mimic gluten’s elasticity.

How do I make this cake vegan?

Replace butter with plant-based margarine or coconut oil, use flaxseed or chia seed eggs, and substitute sour cream with coconut yogurt or a vegan sour cream alternative. Adjust frosting ingredients accordingly.

Can I prepare the cake in advance?

Absolutely. Bake and cool the layers a day ahead. Assemble and frost just before serving to maintain freshness. The flavors often deepen overnight, making it even more delicious.

What if I don’t have instant coffee powder?

You can brew a strong cup of coffee and reduce it to a concentrated syrup, then incorporate it into the batter and frosting for a similar flavor profile.
