Genoise is a classic Italian sponge cake that relies on the air whipped into eggs for its light, airy texture. This 5-egg genoise recipe is perfect for layered cakes, roulades, or as a base for elaborate desserts, offering a tender crumb and rich flavor with minimal ingredients.
Ingredients
- 5 large eggs, at room temperature
- 150 grams (¾ cup) granulated sugar
- 125 grams (1 cup) all-purpose flour, sifted
- 30 grams (2 tablespoons) unsalted butter, melted and cooled (optional)
- 1 teaspoon vanilla extract (optional)
Instructions
- Prepare your equipment: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper. Have a clean, dry mixing bowl and an electric mixer or whisk ready.
- Whip the eggs and sugar: In a large mixing bowl, combine the eggs and sugar. Using an electric mixer on medium-high speed, beat the mixture until it becomes thick, pale, and triples in volume. This can take about 8-10 minutes. The batter should fall in thick ribbons when you lift the whisk.
- Incorporate flavoring (optional): Gently fold in vanilla extract if using, just until combined.
- Fold in the flour: Sift the flour over the whipped eggs in three additions. Using a large silicone spatula or a whisk on low speed, gently fold in each addition carefully to avoid deflating the batter. Use a gentle, sweeping motion from the bottom up.
- Add melted butter (optional): If using, gently fold in the cooled melted butter to add richness. Be careful not to deflate the batter.
- Transfer to the pan: Pour the batter into your prepared cake pan. Smooth the top with a spatula.
- Bake: Place in the preheated oven and bake for 25-30 minutes. The cake is done when a toothpick inserted into the center comes out clean and the top springs back when lightly pressed.
- Cool: Remove from the oven and let it cool in the pan for about 10 minutes. Then, turn out onto a wire rack and cool completely before slicing or decorating.
Tips
- Egg temperature matters: Using eggs at room temperature helps achieve maximum volume when whipping.
- Folding technique: Be gentle when folding in the flour to maintain the airiness of the batter. Overmixing can deflate the mixture, resulting in a denser cake.
- Optional butter: Adding melted butter enriches the cake but isn’t necessary. If added, ensure it’s cooled to prevent collapsing the batter.
- Storage: Genoise keeps well for up to 2 days at room temperature if wrapped tightly. For longer storage, refrigerate in an airtight container for up to 4 days or freeze for up to 3 months.
- Common mistake: Overbaking can dry out the cake. Start checking doneness at the 25-minute mark.
Serving Suggestions
Genoise is incredibly versatile. Serve it plain with a dusting of powdered sugar, or use it as a base for layered cakes with buttercream, fruit preserves, or whipped cream. It also pairs beautifully with fresh berries and a drizzle of chocolate or liqueur for an elegant dessert.
Variations
- Chocolate Genoise: Add 2 tablespoons of cocoa powder to the flour before sifting for a chocolaty twist.
- Fruit-Infused: Fold in finely chopped dried fruits or citrus zest into the batter for added flavor.
- Vegan Version: Substitute eggs with aquafaba (chickpea brine) and use plant-based butter or oil.
- Gluten-Free: Replace all-purpose flour with a gluten-free flour blend, adding a teaspoon of xanthan gum for structure.
Storage and Reheating
Unfrosted genoise can be stored at room temperature, wrapped tightly in plastic wrap, for up to 2 days. For longer storage, refrigerate in an airtight container for up to 4 days or freeze for up to 3 months. To reheat, bring to room temperature or warm gently in a low oven (about 300°F/150°C) for 10 minutes. Avoid microwaving as it can make the cake rubbery.
Frequently Asked Questions
Can I make genoise ahead of time?
Yes, you can prepare the cake a day in advance. Wrap it tightly in plastic wrap and store at room temperature or refrigerate. If refrigerated, bring it to room temperature before serving for optimal texture.
Why is my genoise dense or rubbery?
This usually happens if the eggs weren’t whipped long enough to incorporate enough air, or if the batter was overmixed after adding the flour, causing deflation. Be patient with the whipping process and fold gently.
Can I freeze genoise?
Absolutely. Wrap the cooled cake tightly in plastic wrap and then in foil. Freeze for up to 3 months. To thaw, leave it at room temperature for about an hour before decorating or serving.
What’s the best way to cut genoise without crumbling?
Use a serrated knife and cut gently with a sawing motion. It helps to chill the cake in the refrigerator for 30 minutes before slicing, which firms up the crumb and makes cutting easier.
Can I add flavors or fillings to this genoise?
Yes, once cooled, you can brush the layers with flavored syrups, spread with jam, or fill with whipped cream and fresh fruit. The neutral flavor of genoise makes it perfect as a blank canvas for many desserts.
Is genoise gluten-free?
Traditional genoise contains wheat flour, so it’s not gluten-free unless you substitute with a gluten-free flour blend. Be sure to check the flour you use for gluten content.
