Rhubarb and Custard Cupcakes

My boyfriends parents have a little rhubarb patch at the end of their garden and every year they dig up lots of rhubarb and crumble becomes a big thing through the summer when its fresh. They also cook and freeze lots ready for winter so they can rhubarb crumble all year round.

Rhubarb and Custard is such a staple flavour. Everyone loves a rhubarb crumble covered in a nice lashing of custard. The snow is coming down outside and a warm bowl of rhubarb crumble and custard is just the ticket except this recipe is not rhubarb crumble.


If your a biscuit fan then you always have a look down the biscuit isle in Tesco. I was looking for some biscuits when I came across the Tesco version of rhubarb and custard creams. I was intrigued about these but immediately I was like cupcakes with this would be great.

If you follow my blog then you know I love a good cupcake and a biscuit combination so this one is to join that category.  The biscuits look just like normal custard creams. However, the cream centre is pink to represent the rhubarb.


The cupcakes have crushed up biscuits in the mixture to add the rhubarb flavour and add some crunch to the mixture. The buttercream is just vanilla with crushed up biscuits and of course the cupcake is topped with a nice custard cream.
