Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
I used a baking spread for the cupcakes and unsalted butter for the buttercream.
You will need fresh raspberries for the cupcakes for the best results.
Freeze dried raspberries are really easy to get hold of online (sometimes they're called freeze dried raspberry crumble). I've also seen them in Sainsburys and Waitrose in the baking section.
My favourite white chocolate to use for the cupcakes and the buttercream is Callebaut, but any good quality white chocolate will work well. I would recommend avoiding cooking or baking chocolate.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
