Chocolate peanut butter fudge cupcakes

I got the recipe from here but adapted it slightly and piped out my icing as well as having a peanut butter chocolate fudge core. I did this by using an apple corer to take out the middle of the cupcake then filling it with some fudge sauce.

Peanut butter chocolate fudge sauce

90 g milk or dark chocolate

3 tbsp golden syrup

1/3 cream

1/2 teaspoon vanilla bean paste

1/3 cup smooth peanut butter

Place the chocolate, golden syrup, cream and vanilla in a saucepan over a very low heat and gently stir till all the chocolate is melted, remove from the heat. Stir in the peanut butter and use when ready.
