Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 20 minutes (plus cooling time)
• Servings: 18
• Yield: 1 (13x9x2-inch) cake
• Dietary Type: Contains nuts, eggs, and gluten

Ingredients

For the Orange Syrup:

• 2 2⁄3 cups granulated sugar
• 1 cup water
• 1 1⁄2 tablespoons fresh orange zest

For the Cake:

• 3 cups whole walnuts (about 12 ounces)
• 3 cups whole almonds (about 12 ounces)
• 1 cup ground graham cracker (approximately 16 zwieback rusks, broken coarsely and ground)
• 1 teaspoon ground cinnamon
• 1⁄3 cup granulated sugar (for the nut mixture)
• 12 large eggs, separated
• 1⁄2 cup granulated sugar (for the yolk mixture)
• 1 tablespoon fresh orange zest
• 1⁄2 teaspoon vanilla extract
• 1⁄2 teaspoon salt
• 1 cup granulated sugar (for the egg white mixture)

Equipment Needed

• 13x9x2-inch metal baking pan
• Small, heavy saucepan
• Food processor or blender
• Electric mixer (stand mixer or hand mixer)
• Two large mixing bowls
• Rubber spatula
• Oven
• Cooling rack
• Whisk (optional, for syrup)

Instructions

1. Prepare the Oven and Pan: Begin by preheating your oven to 350°F (175°C). Generously butter and flour your 13x9x2-inch metal baking pan, ensuring all surfaces are coated to prevent sticking.

2. Make the Orange Syrup: In a small, heavy saucepan, combine 1 cup of granulated sugar, 1 cup of water, and 1/2 tablespoon of orange zest. Bring this mixture to a boil over medium heat, stirring often to ensure the sugar dissolves completely. Once boiling, continue to boil for 2 minutes. Remove the saucepan from the heat. Refrigerate this syrup, uncovered, until it is cold. This chilling step is crucial for its absorption into the hot cake.

3. Prepare the Nut and Graham Cracker Mixture: In a food processor or blender, combine the walnuts, almonds, ground graham cracker, ground cinnamon, and the 1⁄3 cup of granulated sugar. Process this mixture until the nuts are finely ground and everything is well incorporated. Be careful not to over-process into a paste; a fine meal consistency is ideal.

4. Prepare the Egg Yolk Mixture: In a large mixing bowl, add the 12 large egg yolks, 1⁄2 cup of granulated sugar, 1 tablespoon of orange zest, and the 1⁄2 teaspoon of vanilla extract. Using an electric mixer, beat these ingredients on medium-high speed until the mixture becomes very thick and pale yellow, which should take approximately 4 minutes. The consistency should be ribbon-like.

5. Whip the Egg Whites: In a separate, clean large mixing bowl, add the 12 egg whites and the 1⁄2 teaspoon of salt. Using clean beaters with your electric mixer, beat the egg whites until they form soft peaks. Gradually add the remaining 1 cup of granulated sugar (for the egg white mixture) while continuing to beat. Beat until the egg whites are stiff but not dry. Stiff peaks mean that when you lift the beaters, the peaks will stand up straight without drooping.

6. Combine the Mixtures: Gently fold the whipped egg whites into the thickened egg yolk mixture using a rubber spatula. Be sure to incorporate them thoroughly without deflating the whites. Then, carefully fold the finely ground nut and graham cracker mixture into the combined egg yolk and egg white batter. Fold until just combined; overmixing can toughen the cake.

7. Bake the Cake: Transfer the batter evenly into the prepared 13x9x2-inch baking pan. Bake in the preheated oven until a knife inserted into the center of the cake comes out clean. This will take approximately 50 minutes.

8. Syrup the Hot Cake: As soon as the cake comes out of the oven, while it is still hot, spoon the cold orange syrup evenly over the entire surface. Allow the syrup to soak into the cake.

9. Cool and Set: Let the cake cool completely in the pan on a wire rack. Once completely cooled, cover the cake and let it stand for up to 1 day. This resting period allows the flavors to meld and the syrup to fully penetrate the cake, resulting in a wonderfully moist texture.

10. Serve: Cut the cake into squares or diamonds for serving.

Expert Tips & Tricks

• Nuts First: Grinding your nuts and graham crackers together is a fantastic shortcut, ensuring even distribution of flavors. If your food processor struggles with the quantity, grind them in batches.
• Egg White Perfection: Ensure your egg white bowl and beaters are scrupulously clean and free of any grease. Even a tiny speck of yolk or fat can prevent your egg whites from reaching their full volume.
• Folding Technique: The key to a light cake is gentle folding. Use a spatula to cut through the center of the batter and bring the batter from the bottom up and over the top. Rotate the bowl and repeat until just combined.
• Syrup Absorption: Spooning the cold syrup over the hot cake creates a delightful contrast and encourages maximum absorption. The steam from the cake will help the syrup meld into its structure.
• Resting is Best: Don’t be tempted to cut into this cake immediately after cooling. The overnight rest truly transforms its texture, making it incredibly moist and flavorful.

Serving & Storage Suggestions

This Walnut and Almond Cake is a delight served on its own, allowing its rich flavors to shine. However, it also pairs beautifully with a dollop of freshly whipped cream, a spoonful of Greek yogurt, or even a side of fresh berries to add a touch of tartness.

For storage, keep the cake covered at room temperature for up to 2 days. If you wish to store it for longer, it can be refrigerated, well-covered, for up to 5 days. Before serving from the refrigerator, allow it to come to room temperature for optimal texture and flavor. This cake freezes exceptionally well; wrap it tightly in plastic wrap and then in foil, and it will keep for up to 3 months. Thaw overnight at room temperature.

Variations & Substitutions

While this cake is spectacular as is, here are a few ideas to explore:

• Nutty Alternatives: If walnuts or almonds aren’t your preference, consider using pecans, hazelnuts, or a blend of your favorite nuts. Ensure the total nut quantity remains consistent.
• Citrus Swap: While orange is divine, you could experiment with lemon zest in the syrup and cake for a brighter, tarter profile.
• Spice it Up: A pinch of ground cardamom or a touch of nutmeg could be added to the dry ingredients for a more complex spice profile.
• Gluten-Free: While this recipe relies on graham crackers for texture, for a gluten-free version, you would need to find a suitable gluten-free cookie or rusk that can be finely ground and tested for binding properties.

FAQs

Q: How do I ensure my nuts are finely ground without turning them into butter?
A: Grind your nuts in short pulses, stopping to shake the food processor between pulses. This allows the larger pieces to fall to the bottom and get ground more effectively, preventing overheating and buttering.

Q: Can I make the orange syrup ahead of time?
A: Yes, you can make the orange syrup up to a day in advance and store it, covered, in the refrigerator. Reheat it gently before pouring over the hot cake, or ensure it’s at room temperature if your cake is still warm.

Q: My cake seems a bit dense. What could I have done wrong?
A: Overmixing the batter after folding in the dry ingredients is a common culprit for dense cakes. Be sure to fold gently and just until combined. Also, ensure your egg whites were whipped to stiff, not dry, peaks.

Q: Can I bake this cake in a different pan size?
A: If you use a smaller pan, the cake will be thicker and may require a longer baking time. A larger pan will result in a thinner cake that bakes more quickly. Always rely on the toothpick test for doneness.

Q: How can I prevent the syrup from making the cake too soggy?
A: The recipe is designed for the syrup to create a moist, almost custardy texture. If you prefer a less syrupy cake, you can try reducing the amount of syrup slightly, but it’s an integral part of the cake’s signature moistness.
