If you’re someone who loves the combination of coconut and chocolate (and honestly, who doesn’t?), these coconut chocolate custard cupcakes are about to become your new obsession. When the tropical aroma and mellow, creamy sweetness of coconut are blended with the richness of dark chocolate, the result is an indulgent yet balanced magic. Soft coconut cupcakes, silky chocolate coconut custard, and a light chocolate Swiss meringue buttercream- every bite is creamy, fluffy, and just indulgent enough without feeling heavy.
The cupcake itself is buttery, fluffy, and lightly textured from shredded coconut, while the filling has a smooth pudding-like consistency with deep chocolate notes and a gentle coconut finish. Then comes the frosting—airy, creamy, and intensely chocolatey without feeling heavy. Together, every layer creates a dessert that tastes luxurious but still light enough for a second cupcake.
These cupcakes are perfect for birthdays, dinner parties, festive gatherings, or rainy-day baking sessions when you want something a little extra special. The coconut also makes them perfect for warmer months and tropical-inspired dessert tables, though honestly, I’d happily eat them year-round straight from the fridge.
If you want to make these filled cupcakes more summery, you should definitely try my Triple Strawberry Cupcakes with Strawberry Swiss Meringue Buttercream (Fresh Strawberry Filled Cupcakes) for a fruity version bursting with fresh strawberries. Also, my Custard Filled Cupcakes are an option if you aren’t a fan of chocolate (I’m judging you).

Possible Substitutions
- Coconut milk → If you are not a fan or cannot get hold of coconut milk, substitute it with regular milk. For a closer match, add a drop of coconut extract.
- Dark chocolate → Milk chocolate works, but reduces intensity and sweetness balance.
- Cornflour → Can be replaced with arrowroot powder in equal quantity. Flavour will change, though.
- Eggs → For cupcakes, egg substitutes like yogurt or buttermilk may work, but the texture will change. Custard and meringue rely heavily on eggs and are harder to substitute.
- Swiss meringue buttercream → Can be replaced with whipped ganache or American buttercream if you want something quicker.
How to make Coconut Chocolate Custard Cupcakes?
1. Make the Coconut Chocolate Custard
Heat the coconut milk until just boiling. In another pan, whisk egg yolks, sugar, cornstarch, and salt until smooth. Slowly pour in ⅓ of the hot milk while whisking (this prevents scrambling). Add remaining milk and mix well.
Cook on medium-low heat, stirring continuously until slightly thickened. Pour over dark chocolate and stir until smooth. Cover with cling film (touching the surface) and cool to room temperature.
Tip: The custard should be slightly runny—perfect for filling!
2. Prepare the Coconut Cupcakes
Preheat oven to 180°C/350°F and line cupcake tray.
Whisk dry ingredients together.
Cream butter and sugar until pale and fluffy. Add eggs one at a time, mixing well after each. Mix in vanilla.
Add dry ingredients and coconut milk alternately in batches. Fold in shredded coconut.
Fill liners ⅔ full and bake for 18–20 minutes. Or until a toothpick/skewer inserted comes out clean or with a few moist crumbs. Cool completely on a wire rack.
Tip: Don’t overmix after adding flour—this keeps the cupcakes soft.
3. Make Chocolate Swiss Meringue Buttercream
Heat egg whites and sugar over a double boiler until sugar dissolves (≈65°C/150°F) or until no grit when rubbed between fingers.
Whip to stiff peaks. Add butter gradually while beating. Continue beating until smooth and creamy. Add cocoa powder and coconut cream. Mix until combined.
Tip: If it looks curdled—keep beating. It will come together!
4. Assemble
Core the center of each cooled cupcake with a knife/melon scooper/piping nozzle. Fill with cooled custard.
Pipe frosting on top. Create a small dent and fill with more custard.
Sprinkle coconut on top. Chill for 20 minutes before serving.
Storage Instructions
Because these cupcakes contain both custard filling and Swiss meringue buttercream, proper storage is important for maintaining freshness and texture.
Room Temperature-In a cool environment, they can sit at room temperature for about 4–6 hours while serving. If your kitchen is warm or humid, refrigerate them sooner to prevent the frosting from softening too much.
Refrigerator– Store the cupcakes in an airtight container in the refrigerator for up to 3–4 days.
Let them sit at room temperature for about 15–20 minutes before serving to soften the buttercream.
Freezer– You can freeze the cupcakes, though freezing and refrigerating individual components work best.
Make-Ahead Instructions
These Coconut Chocolate Custard Cupcakes are great for preparing in stages, making them ideal for parties, celebrations, or busy baking schedules.
Cupcakes– The coconut cupcakes can be baked 1 day ahead and stored in an airtight container at room temperature. You can also freeze the cupcakes up to 2 months ahead.
- Avoid refrigerating unfrosted cupcakes since refrigeration can dry them out.
Coconut Chocolate Custard:
The custard can be prepared up to 2 days in advance. Store it in the refrigerator with cling film pressed directly onto the surface to prevent a skin from forming. Before using, give it a quick stir to loosen the consistency if needed.
- The custard can technically be frozen, but its texture may change slightly after thawing. Refrigeration is recommended instead.
Buttercream: The buttercream can be made 2–3 days in advance and refrigerated. Bring it back to room temperature before use.
Swiss meringue buttercream freezes very well for up to 1 month. Thaw overnight in the refrigerator and re-whip briefly before using.
Full Assembly– Assemble the cupcakes the day you plan to serve them. If needed, fully assembled cupcakes can be refrigerated overnight. The flavours actually deepen slightly after chilling, making them even more delicious the next day.
FAQs (Schema-Friendly)
Q: Can I make these cupcakes eggless?
A: The cupcake base can be adapted, but custard and Swiss meringue rely heavily on eggs.
Q: Why is my buttercream curdled?
A: It’s likely a temperature issue—keep beating and it should smooth out.
Q: Can I skip the filling?
A: Yes, but the custard adds a signature creamy texture.
Q: How do I know when cupcakes are done?
A: A toothpick inserted should come out with a few dry crumbs.

Coconut Chocolate Custard Cupcakes
Ingredients
Method
- In a saucepan, heat the coconut milk over medium heat until it just begins to boil. Stir occasionally to prevent scorching.
- Meanwhile, in another saucepan or heatproof bowl, whisk together the egg yolks, sugar, cornstarch (cornflour), and salt until smooth and lump-free.
- While whisking continuously, slowly pour in about one-third of the hot coconut milk. This step tempers the egg yolks and prevents scrambling.
- Add the remaining hot coconut milk and whisk until fully combined.
- Place the saucepan over medium-low heat and cook while whisking continuously. Make sure to scrape the bottom and sides of the pan to avoid lumps.
- Continue cooking until the custard thickens slightly. The consistency should remain pourable and slightly runny since it will thicken more while cooling.
- Remove from heat and immediately pour the hot custard over the dark chocolate placed in a bowl.
- Stir until the chocolate melts completely and the custard becomes smooth and glossy.
- Cover the surface directly with cling film to prevent a skin from forming. Let it cool to room temperature before using.
- Preheat the oven to 180°C/350°F. Line a cupcake tray with cupcake liners.
- In a medium bowl, whisk together the all-purpose flour, cornflour, baking powder, and salt. Set aside.
- In a large bowl, beat the butter and sugar together until pale, creamy, and fluffy. This may take about 3–5 minutes.
- Add the eggs one at a time, beating well after each addition until fully incorporated.
- Add the vanilla extract and mix until combined.
- Add the dry ingredients and coconut milk alternately in 2–3 additions, beginning and ending with the dry ingredients. Mix only until combined after each addition.
- Fold in the shredded coconut using a spatula.
- Fill the cupcake liners about two-thirds full.
- Bake for 18–20 minutes or until a toothpick inserted into the center comes out with a few dry crumbs.
- Allow the cupcakes to cool in the tray for 5 minutes before transferring them to a wire rack to cool completely.
- Add the egg whites, sugar, and salt to a heatproof bowl.
- Place the bowl over a saucepan containing simmering water. Ensure the bottom of the bowl does not touch the water.
- Whisk continuously until the sugar completely dissolves and the mixture reaches approximately 65°C/150°F. When rubbed between your fingers, the mixture should feel smooth without any sugar granules.
- Remove the bowl from heat and beat the mixture using an electric mixer until stiff, glossy peaks form and the bowl no longer feels warm.
- Add the softened butter gradually, one portion at a time, beating well after each addition.
- Continue beating until the buttercream becomes smooth, creamy, and stable. If it looks curdled at any stage, keep beating—it will come together.
- Sift in the cocoa powder and add the coconut cream. Beat until fully incorporated and smooth.
- Once the cupcakes have completely cooled, create a cavity in the center of each cupcake using a piping nozzle, melon baller, or knife.
- Fill each cavity with the cooled coconut chocolate custard using a spoon or piping bag.
- Pipe the chocolate Swiss meringue buttercream on top of each cupcake.
- Use a small spoon to create a shallow dent in the frosting.
- Sprinkle shredded coconut over the frosting.
- Pipe or spoon additional custard into the dent on top.
- Refrigerate the cupcakes for about 20 minutes before serving for the best texture and clean presentation.
