On our anniversary morning I whipped up a breakfast picnic (to be had on our bedroom floor!) and popped a letterpress number four on top of the cake. You should of seen his face (actually and mine) when he cut inside.
I am Baker. You should most def check out her creations... I take no responsibility however for your wasted time pouring over her cakes though, or attempts at making them (this took me around 6 hours).
