Classic Walnut Cake Recipe
This elegant yet approachable cake highlights the flavor and texture of walnuts while balancing sweetness and richness. Perfect for afternoon tea, dessert, or a celebratory event.
Ingredients
- 5 1/2 tablespoons (80 grams) unsalted butter, plus more for greasing
- 1 cup (150 grams) walnuts, plus 5 walnut halves for decoration
- 2/3 cup (130 grams) granulated sugar
- 3 large eggs
- 3 tablespoons dark rum
- 1 tablespoon honey, plus more for drizzling
- 1/2 teaspoon vanilla extract
- Pinch of fine sea salt
- 1/3 cup (40 grams) all-purpose flour, sifted
- 1/4 cup (30 grams) cornstarch
- 1 teaspoon baking powder
- Confectioners’ sugar (for dusting)
- Whipped cream (for serving)
Preparation Steps
- Preheat oven to 350°F (180°C). Grease a 7-inch (18 cm) Bundt pan with butter.
- Chop walnuts. Finely chop or pulse in a food processor until coarse crumbs.
- Mix core ingredients. In a large bowl, combine walnuts, sugar, butter, eggs, rum, honey, vanilla, and salt. Mix thoroughly.
- Mix dry ingredients. In another bowl, whisk flour, cornstarch, and baking powder together.
- Combine mixtures. Fold dry ingredients into the walnut mixture gently but thoroughly.
- Bake. Pour batter into the prepared pan and bake for about 40 minutes, or until a knife inserted in the center comes out clean.
- Cool. Let the cake cool in the pan for 10 minutes after unmolding.
- Decorate. Sprinkle a dash of confectioners’ sugar in a small sauté pan, add reserved walnut halves and cook until golden. Arrange on top of the warm cake and drizzle with honey before serving. Accompany with whipped cream.
Key Techniques for Success
- Chopping Walnuts: The size of chopped walnuts affects texture; fine crumbs yield a soft crumb, while coarser pieces add bite.
- Mixing Wet and Dry Ingredients: Incorporate gently to retain maximum air and avoid overworking the batter.
- Decoration: Toast walnuts in sugar for topping adds crunch and aesthetic appeal.
- Serving Suggestion: Drizzle extra honey and serve with a dollop of whipped cream for sophistication.
Flourless Walnut Cake Variation
For a lighter, gluten-friendly treat, the flourless walnut cake uses just nuts, eggs, and sugar for structure. Rich in flavor, airy in texture, and simple to make, it demonstrates the versatility of walnut cakes.
Ingredients
- 8 ounces ground walnuts
- 9 ounces fine sugar
- 6 eggs, at room temperature
- 8 walnut halves for decoration
- Icing sugar (for dusting)
- Whipped cream (for serving)
Directions
- Butter and flour a 9-inch pan, then preheat oven to 350°F (175°C).
- Separate egg yolks from whites. Beat sugar and yolks until very fluffy and light, 8–10 minutes.
- Fold ground walnuts into the yolk mixture.
- Beat egg whites to soft peaks. Fold delicately into the walnut-yolk mix in three parts.
- Pour mixture into prepared pan; bake 30–40 minutes or until set but moist.
- Cool in pan for 5 minutes, then turn onto a rack.
- When cool, dust with icing sugar, decorate with walnut halves, and serve with whipped cream.
Tips for Flourless Cake Success
- Beat yolks and sugar long enough to incorporate air, resulting in cake lift.
