Instructions
Creating this flourless walnut cake is a rewarding process that yields a surprisingly tender and flavorful result. The key lies in the gentle folding and the precise baking.
- Begin by preheating your oven to 375°F (190°C). This steady, moderate heat is crucial for the cake to bake evenly without burning.
- Prepare your 8-inch round cake pan. Lightly butter the inside of the pan, ensuring all surfaces are coated. Then, lightly flour it. If you’re concerned about sticking, you can also line the bottom with a round of parchment paper after buttering and flouring.
- In a medium mixing bowl, combine the egg yolks and 1 cup of Splenda® granular. Using an electric mixer, beat these together until the mixture becomes pale yellow, light, and significantly fluffy. This process should take approximately 4 minutes. The aeration here is vital for the cake’s structure.
- Once the egg yolk mixture is ready, stir in the freshly grated lemon zest. This bright, aromatic addition will cut through the richness of the walnuts and add a lovely nuance to the finished cake.
- In a separate, impeccably clean medium mixing bowl, beat the egg whites until they hold stiff peaks. This means that when you lift the whisk, the peaks of the egg whites should stand straight up without curling over. This is where the leavening and lightness of the cake will come from.
- Now, to gently combine the two mixtures, fold one quarter of the beaten egg whites into the egg yolk mixture. This initial addition is to lighten the denser yolk mixture, making it more receptive to the remaining whites. Use a rubber spatula and a gentle folding motion, cutting down through the center of the bowl and then sweeping around the sides.
- Next, add the finely ground walnuts to this lightened yolk mixture. Stir them in until they are thoroughly blended. Ensure there are no dry pockets of walnuts.
- With the walnuts incorporated, it’s time to carefully fold in the remaining egg whites. Again, use that same gentle folding motion. The goal here is to incorporate the whites without deflating them, thereby maintaining the airy texture that will give the cake its delicate crumb.
- Once the batter is homogeneous and has a light, fluffy consistency, pour it into the prepared cake pan. Spread it evenly.
- Bake in the preheated oven for approximately 60 minutes, or until the cake is firm to the touch and has a beautiful golden-brown hue. A skewer or toothpick inserted into the center should come out clean when the cake is done. Oven temperatures can vary, so keep an eye on it, especially in the last 15-20 minutes.
- Once baked, carefully remove the cake from the oven. Place the pan on a wire cooling rack and allow the cake to cool in the pan for about 10-15 minutes before attempting to invert it.
- After the initial cooling in the pan, invert the cake onto the wire cooling rack to cool completely. This ensures the bottom doesn’t become soggy.
Expert Tips & Tricks
- Walnut Grinding: For the best texture, grind your walnuts just before using them. Avoid over-processing them into a paste; you want a fine, crumbly texture. A food processor is ideal for this, pulsing until the walnuts reach the desired consistency.
- Egg White Perfection: Ensure your bowl and whisk for beating egg whites are completely free of any grease or egg yolk. Even a tiny trace can prevent the whites from reaching stiff peaks.
- Gentle Folding is Key: This is perhaps the most crucial step in achieving a light and airy flourless cake. Imagine you’re trying not to bruise the egg whites – this will help you maintain their structure.
- Doneness Test: While a skewer test is reliable, you can also gently press the top of the cake. If it springs back slightly and feels firm, it’s likely done. A slightly domed top that begins to pull away from the sides of the pan is another good indicator.
- Room Temperature Eggs: For both the yolks and whites, using eggs at room temperature will result in greater volume when beaten.
Serving & Storage Suggestions
This flourless walnut cake is a masterpiece on its own, but a little embellishment can elevate it further.
- Serving: Once the cake is completely cool, you can serve it as is, allowing its natural nutty flavor to be the star. For a touch of elegance, dust alternately with powdered sugar and cocoa powder using a fine-mesh sieve. The contrasting colors are visually appealing. Arrange fresh berries around the plate for a burst of color and freshness. This cake is also wonderful served with a dollop of lightly sweetened whipped cream or a simple crème anglaise.
- Storage: This cake is best enjoyed at room temperature. Store any leftovers in an airtight container at room temperature for up to 3 days. The moisture content is lower than in traditional cakes, so it holds up well. If you need to store it for longer, it can be refrigerated for up to a week, though it may firm up slightly. Bring it back to room temperature before serving. Freezing is also an option; wrap it tightly in plastic wrap and then in foil, and it should keep well for up to 2 months. Thaw overnight in the refrigerator.

Variations & Substitutions
While this recipe is a classic for a reason, here are a few ways you can adapt it:
- Nutty Swap: Pecans can be used in place of walnuts for a slightly different, sweeter flavor profile. Almonds are another excellent option, though they might yield a slightly different texture.
- Sweetener Adjustment: If you prefer not to use Splenda®, you can experiment with other granular sweeteners that measure cup-for-cup like the Splenda® granular. You may need to adjust the amount slightly based on the sweetness of your chosen substitute.
- Flavor Boost: For an extra layer of flavor, consider adding a teaspoon of pure vanilla extract to the egg yolk mixture or a pinch of cinnamon and nutmeg when you add the ground walnuts.
FAQs
Q: Why is this cake flourless?
A: Flourless cakes rely on eggs and finely ground nuts (or other ingredients like chocolate) for their structure and texture, rather than traditional wheat flour.
Q: How do I ensure my egg whites whip up properly?
A: Make sure your bowl and whisk are completely clean and free of any grease. Room temperature eggs also whip up better.
Q: Can I make this cake ahead of time?
A: Yes, this cake is an excellent candidate for making ahead. It stores well at room temperature for a few days.
Q: My cake seems a little dense. What could have gone wrong?
A: This is often due to overmixing the batter after adding the egg whites, which deflates them. Gentle folding is key to a lighter cake.
Q: What kind of wine pairs well with this cake?
A: A Late Harvest Riesling or a Sweet Orange Muscat are excellent choices, their sweetness and fruitiness beautifully complementing the nutty richness of the cake.
