Citrus Burst Cupcakes

Why I Love This Recipe
After making some cupcakes for my mum's work my dad insited that it wasn't fair and people at his work would enjoy them too! So since I didn't want to make the same cupcake again, as I love trying new recipes, I thought that a Citrus Burst cupcake would be nice. An orange cake with a lemon frosting topped with a lemon or orange jelly sweet. :).
