Tips For Perfect Moist Custard Cream Cupcakes Every Time
Always use room temperature ingredients. Cold butter does not cream well. Cold eggs curdle batter. So keep butter and eggs out 1 hour before baking.
Always weigh ingredients with digital scale. Cups give different results. Scale gives perfect results. Therefore bakery texture comes.
Do not open oven door early. Early opening drops temperature. Cupcakes sink in middle. Wait at least 20 minutes before checking.
Use good quality custard powder. Bird’s custard powder gives best yellow color and flavor. Cheap powder gives dull taste.
Add biscuit topping only at serving time. Biscuit soaks moisture from cream. So it turns soft quickly. Fresh biscuit stays crunchy.
Variations You Can Try
You can make chocolate version. Replace 20gm flour with cocoa powder. Then you get chocolate custard cupcakes. Kids love chocolate.
You can make extra creamy version. Add 1 tbsp custard filling inside hole plus swirl. Then you get double custard flavor.
You can make mini version. Use mini liners. Bake for 15 minutes only. Mini size suits parties.
You can make dairy free version easily. Use dairy free butter and oat milk. Also buy dairy free custard powder and biscuits. Then you get dairy free treat.
How To Store Custard Cream Cupcakes
Store cupcakes in airtight container for 2-3 days. Keep container in cool place. Fridge works too. But bring to room temp before serving. Cold dulls flavor.
Freeze sponge without frosting for 2 months. Wrap each sponge in cling film. Place in freezer box. Thaw at room temp for 2 hours.
Freeze buttercream separately in sealed jar for 1 month. Thaw in fridge overnight. Re-whip before use. So you can prep ahead for parties.
Can You Use Plain Flour?
Yes, you can. UK shops sell self-raising flour easily. But USA and other places use plain flour more. So add 2 tsp baking powder and pinch salt to 150gm plain flour. Mix well. Then use. This trick helps you make Custard Cream Cupcakes UK recipe anywhere in world.
Some people skip salt. So you can skip if you want. Cake still bakes fine.
Can You Make Gluten Free?
Yes, you can make gluten free version. Buy gluten free self-raising flour. Also buy gluten free custard cream biscuits. Many supermarkets sell them now. Check label for hidden gluten. Replace same amounts. Bake same time. You get same soft taste.
For dairy free, use vegan butter and biscuits. Oat milk works best. Almond milk also works. So everyone can enjoy Homemade Custard Cream Cupcakes.
Important Tools You Need
You need electric hand mixer or stand mixer. Mixer makes buttercream fluffy quickly. Hand whisk takes longer and tires arm.
You need piping bag and star nozzle. Nozzle creates bakery style swirl. Without nozzle, swirl looks flat.
You need cookie cutter or cupcake corer for filling hole. Knife also works. But corer makes neat hole.
Common Mistakes To Avoid
Do not use melted butter. Melted butter makes greasy cupcakes. Use soft butter only. Soft butter holds air.
Do not overfill liners. Overfilled cupcakes spill over. They look messy. Fill 2/3 only.
Do not frost warm cupcakes. Warm melts buttercream. Frosting slides off. Wait till fully cool.
Do not skip sifting sugar. Unshifted sugar leaves lumps in frosting. Sifted sugar gives smooth cream.
