- 2 teaspoons Vanilla extract
- 185 g All purpose flour
- ½ teaspoon Baking powder
- ½ teaspoon Salt

- ½ teaspoon White vinegar
Swiss Meringue Buttercream
- 200 g Granulated sugar
- 120 g Egg whites
- 226 g Unsalted butter (room temperature)
- ½ tablespoon Vanilla extract
- ¼ teaspoon Salt
Mango Curd
- 80 g Mango puree (fresh or frozen, measured after pureeing)
- ½ tablespoon Freshly squeezed lemon juice
- 2 Egg yolks
- 50 g Granulated sugar (adjust based on mango sweetness)
- 40 g Unsalted butter (room temperature; for thicker curd, use 110 g)
Instructions
- Prepare the cupcake tin and oven: Line your cupcake tin with muffin liners and preheat the oven to 175℃ (347℉) without fan.
- Make the vanilla cupcake batter: In a large bowl, cream the room-temperature butter with sugar until light and fluffy. Add eggs one at a time, mixing well after each, then stir in vanilla extract.
- Combine dry ingredients and mix: Sift together flour, baking powder, and salt. Add the dry ingredients to the butter mixture in three parts, alternating with room-temperature milk, mixing on low speed. Avoid overmixing.
- Add baking soda and vinegar: In a small bowl, mix the vinegar with baking soda until bubbly, then fold immediately into the batter just until combined.
- Bake the cupcakes: Fill cupcake liners about three-quarters full with batter. Bake for 20-22 minutes until a toothpick inserted comes out clean. Cool completely on a rack before frosting.
- Prepare Swiss meringue buttercream – step 1: Bring butter to room temperature. In a double boiler (bowl over simmering water), whisk egg whites and sugar until sugar dissolves and mixture reaches 160°F (71°C).
- Prepare Swiss meringue buttercream – step 2: Transfer mixture to stand mixer bowl; whisk on high for about 6 minutes until shiny, stiff peaks form and bowl is no longer warm.
- Add butter to meringue: Switch to paddle attachment and add softened butter tablespoon by tablespoon on medium speed. After all butter is incorporated, whip on medium-high speed for 4 more minutes until light and fluffy.
- Flavor and finish buttercream: Add vanilla extract and salt, whisk for another minute until smooth and silky. If too thin, refrigerate for 30 minutes.
- Make mango curd – combine ingredients: In a heavy saucepan over low-medium heat, combine mango puree, lemon juice, egg yolks, and sugar. Stir until sugar dissolves.
- Add butter and cook: Add softened butter in four stages, stirring until melted and incorporated. Cook over medium heat, stirring constantly until custard thickens and coats the back of a spoon (~5 minutes), reaching about 80°C (176°F).
- Strain and chill mango curd: Remove from heat; strain through a sieve into a container. Cover with plastic wrap touching the surface to prevent skin. Refrigerate at least 4 hours or overnight.
- Assemble cupcakes: Create a small hole in each cooled cupcake and fill with ½ tablespoon mango curd. Pipe Swiss meringue buttercream over the top and decorate with fresh mango slices, mint, or edible flowers as desired.
- Storage and serving: Best served fresh. Store leftovers in an airtight container in the fridge for 2-3 days. Bring to room temperature before serving to soften frosting.
Notes
- Use room temperature ingredients for better batter consistency and aeration.
- Do not overbake cupcakes to keep them moist and tender.
- Ensure butter for buttercream is soft but not melted for optimal texture.
- Constant stirring during mango curd cooking prevents curdling and ensures smooth custard.
- If the Swiss meringue buttercream is too thin, chilling it briefly helps it firm up.
- Adjust mango curd sugar depending on the sweetness of your mangoes.
- Allow cupcakes to cool completely before filling and frosting to avoid melting the buttercream.
