The three-ingredient mousse is studded with vanilla bean seeds for extra aroma and whips into an airy, decadent topping. The contrast of tender vanilla cake, juicy strawberries, and smooth white chocolate frosting makes these cupcakes an ideal treat for warm weather and strawberry season.

📝 Key ingredients

Full steps and ingredient amounts appear in the recipe card below.

White chocolate: Use good-quality white chocolate bars for best flavor and a smooth mousse.
Heavy whipping cream: Full-fat (about 35%) cream whips to stable peaks for the mousse.
Buttermilk: Store-bought buttermilk or kefir gives good texture and flavor; you can make a quick substitute by adding 1 teaspoon vinegar to ½ cup milk and letting it rest 10 minutes.
Olive oil + butter: A mix of oil and butter keeps the cupcakes tender while adding buttery flavor. Neutral vegetable oil works too if preferred.
Fresh strawberries: Macerating strawberries with sugar and lemon intensifies their flavor and produces a lovely syrup to fill the cupcakes.
All-purpose flour: Weigh the flour for reliable results. If measuring by cup, gently spoon it into the cup and level without packing.
👩🍳 How to make white chocolate fresh strawberry cupcakes
Macerated strawberries — step by step

Step 1: Hull and chop fresh strawberries into small pieces and place them in a bowl.

Step 2: Add sugar, salt, and lemon juice, mix, cover, and refrigerate while you bake and prepare the mousse. The fruit will release syrup as it macerates.
Vanilla cupcakes — step by step
Prep: Line a 12-cup muffin tin and preheat the oven to 355°F (180°C).

Step 1: Beat sugar, softened butter, and oil until pale and fluffy.

Step 2: Add eggs one at a time, beating well after each addition.

Step 3: Mix in buttermilk, vanilla, and salt until combined.

Step 4: Sift in flour and baking powder and fold gently just until a thick batter forms. Do not overmix.

Step 5: Spoon batter evenly into liners and bake 16–18 minutes, or until a toothpick comes out mostly clean with a few crumbs.

Step 6: Cool cupcakes completely before filling and frosting. Removing them from the pan while still slightly warm helps prevent sticking.
White chocolate mousse — step by step

Step 1: Gently heat the cream, chopped white chocolate, vanilla, and salt in a small saucepan until the chocolate melts. Do not boil; remove from heat and chill until cold in the fridge.

Step 2: Whip the chilled mixture to stiff peaks just before frosting. It whips quickly, so watch closely to avoid overwhipping and graininess.
Assembly — step by step

Step 1: Trim a shallow well in the center of each cupcake (only about halfway through) and reserve the removed cake pieces for snacking.

Step 2: Fill the wells with macerated strawberry pieces and drizzle a small amount of the strawberry syrup over each filling.

Step 3: Pipe or spread the white chocolate mousse on each cupcake, creating a small well on top to hold extra strawberries.

Step 4: Just before serving, top with remaining macerated strawberries (avoid excess syrup) and garnish with edible flowers if desired.
✔️ Expert cupcake tips
- Weigh your flour: A scale gives the most consistent results. If using cups, spoon flour into the cup and level it off—don’t pack.
- Don’t overmix: Mix batter gently; small lumps are fine and help keep cupcakes tender.
- Add macerated strawberries at the last minute: Top cupcakes with macerated fruit just before serving so they stay glossy and fresh-looking.
- Watch the mousse when whipping: White chocolate ganache whips faster than plain cream; stop as soon as you reach stiff peaks to prevent graininess.

🥄 Make ahead and storage
Because of the fresh fruit and mousse, filled and frosted cupcakes must be refrigerated. Store them in an airtight container in the fridge for up to 3 days for best quality.
How far ahead you can prepare components:
Vanilla cupcakes: Bake up to 3 days before filling and frosting. Store in an airtight container in the fridge for up to 2 days, or freeze for up to 2 months.
Macerated strawberries: Prepare up to 12 hours in advance.
White chocolate mousse: Prepare the melted white chocolate mixture and chill up to 2 days before whipping and using.

📖 Recipe FAQs
Yes. For blueberries, lightly mash them so the sugar dissolves and produces a syrup during maceration.
Yes. Milk or dark chocolate can be used; they will also create a mousse when combined with cream and whipped.
It’s best to add macerated strawberries just before serving. Leftover topping can make the frosting soggy and the fruit lose its shine.
You can try substituting with a 1:1 gluten-free flour blend or use your favorite gluten-free vanilla cupcake recipe and follow the same filling and frosting steps.
