Step-by-step instructions
This section walks you through the Genoise Shortcake with Fresh Strawberries and Vanilla Swiss Buttercream in beginner-friendly steps.
- Preheat and prep
- Preheat oven to 350°F (175°C). Line an 8-inch round cake pan with parchment and lightly grease sides.
- Whisk eggs and sugar
- In a large mixing bowl, whisk the eggs and sugar together over a simmering water bath until warm to the touch and sugar dissolves, about 3–4 minutes. Remove from heat and beat on high until the batter triples in volume and forms a ribbon when lifted, about 6–8 minutes.
- Fold in flour and butter
- Gently fold sifted flour and salt into the whipped eggs in two additions, keeping as much air as possible. Fold in the cooled melted butter and vanilla with a light touch.
- Bake and cool
- Pour into the prepared pan and bake 20–25 minutes, until the top is golden and springs back lightly. Let cool in pan 10 minutes, then invert onto a rack to cool completely.
- Make the Vanilla Swiss Buttercream
- In a heatproof bowl, whisk egg whites and sugar. Place over simmering water and whisk until sugar dissolves and mixture registers 160°F (71°C). Whisk into a stand mixer and beat to stiff peaks. With mixer on low, slowly add softened butter, then beat until smooth and silky. Stir in vanilla and salt.
- Assemble shortcakes
- Slice the genoise into layers or split horizontally into 2–3 discs. If making individual shortcakes, cut rounds. Macerate strawberries with a touch of sugar if desired. Layer cake, a smear of Swiss buttercream, whipped cream, and strawberries. Finish with a delicate swirl of buttercream and extra berries.

Tips for success
Baking genoise and assembling this Genoise Shortcake with Fresh Strawberries and Vanilla Swiss Buttercream is simple when you follow a few friendly tips.
- Temperature matters: Bring eggs and butter to room temperature for better volume and incorporation.
- Gentle folding: Preserve the whipped eggs’ air by folding with a light hand using a rubber spatula.
- Test doneness: Use the spring-back test rather than relying solely on time — genoise should be springy and lightly golden.
- Buttercream texture: If your Swiss buttercream looks curdled, keep beating — it will come together as the butter fully softens. For a quick snack while waiting, try a crisp air-fryer side: air-fryer beef and broccoli.
Possible variations
Give your Genoise Shortcake with Fresh Strawberries and Vanilla Swiss Buttercream a twist depending on dietary needs and flavor preferences.
- Gluten-free: Substitute a 1:1 gluten-free flour blend, but handle batter gently to preserve structure.
- Streusel topping: Add a crunchy almond streusel on top for texture — sprinkle before serving rather than baking.
- Citrus note: Fold in a teaspoon of lemon zest to the genoise for brightness.
- Alternative berries: Swap strawberries for raspberries or sliced peaches when in season. For a quick seaside picnic pairing, consider a crisp side dish like air-fryer fish and chips.
Storage recommendations
- Refrigerate: Store assembled shortcakes in an airtight container in the fridge up to 2 days for best texture; whipped cream will soften over time.
- Freeze layers: Wrap cooled genoise layers tightly and freeze up to 1 month. Thaw in the fridge before assembling with buttercream and berries.
- Assemble before serving: For the freshest look and texture, keep strawberries and whipped cream separate until just before serving.

FAQs
Q: What is the difference between genoise and sponge cake?
A: Genoise is a type of sponge cake that relies on whole eggs whipped with sugar for leavening, often with a touch of melted butter for richness, producing a light but slightly drier crumb that pairs well with creams and fillings.
Q: Can I make the Swiss buttercream ahead of time?
A: Yes — Swiss buttercream can be made up to three days ahead and refrigerated in an airtight container. Bring to room temperature and re-whip before using for a smooth consistency.
Q: How do I stop my genoise from collapsing?
A: Avoid overmixing after folding in flour, and ensure the whisked eggs have reached full volume before folding. Cool gently and avoid rapid temperature changes.
Q: Can I use frozen strawberries?
A: Frozen strawberries can be used, but they release more liquid when thawed. Drain excess juice or gently macerate and use as a compote rather than fresh slices for best texture.
