Toast bread in toaster, butter both sides and then bake in oven further until nice and crispy.
Cool toast then blitz in a food processor and set aside.
For the cupcakes, sift together all the dry ingredients followed by approximately 25g of the toast crumbs (don't worry about trying to get this through a sieve) in to a free-stand mixer.
Add the eggs and butter and beat for 1 minute.
Lower the speed and add the milk and 1 tablespoon of marmalade before turning mixer back up for 1 more minute, not forgetting to scrape down the sides during.
Fill paper case about two-thirds full.
Bake between 16-20 minutes or until cake springs back when touched.
Optional: When cupcakes a cool, core out the centre of the cupcakes and pipe a small about of marmalade directly into the centre of the cake for a nice fruity surprise.
Leave cupcakes out to cool while we move onto the buttercream.
Beat butter in free-standing mixer for 5 minutes, scraping sides down occasionally.
Sift icing sugar and add to the butter in two stages, beating for another 3 minutes between additions.
On a slow speed add the marmalade, orange zest and finally the milk.
Turn mixer speed back up for another 5 minutes.
Once the cupcakes are cool pipe a big swirl of marmalade buttercream on the top, sprinkle with any remaining toast crumbs, decorate with a couple slices of orange peel and enjoy with a cup of tea.
