Filled cupcake day

Well I wanted to try something different so decided to make some lemon curd cupcakes. While shopping I was assured by hubby there was a jar in the fridge. Getting home, there may have been a jar but it only contained 3 teaspoons of lemon curd. So they became peanut butter cupcakes. lol. However I guess you can use anyhing similar. My next one will be nuttella I think. :)
You will need:
- jar of peanut butter/lemon curd
- 100g margarine
- 100g caster sugar
- 1 medium eggs
- 100g self raising flour

1- Heat oven to gas mark 5. Put paper cases into tray.
2- cream margarine and sugar together. beat in eggs one at a time adding a little of the flour with each.
3- Fold in the rest of the flour.

4- Put a teaspoon of cake mixture into the bottom of each of the cases.
5- Put a teaspoon of peanut butter/lemon curd into the middle of the case, on top of the mixture.

6- Put some more mixture on top to cover the peanut butter

7- Bake for aprox 15 minutes or until firm.

8 - Enjoy!

I was going to make some butter cream for these but Mark says the filling is quite rich so doesn't need it. However I'll do a butter cream recipe later today in case you disagree. :)
