The cake is so called because it only takes 5 minutes to prepare and 25 minutes to bake, a quick and easy recipe to whip up when an unexpected visitor calls. I saw a picture on Pinterest and it led me to this blog post where I got the instructions.

I made a few adjustments - orange zest instead of the lemon, walnut pieces instead of almond slices. Worked just as nice, and I am satisfied with the outcome! Perfectly in time for afternoon tea :)
In a bowl, pour 1C sugar, and orange zest. Rub to flavour the sugar. Whisk in 2 eggs, one at a time. Add 1/4t salt, 1t vanilla. Next comes 1C flour, and 8T melted and cooled butter. Into the cake pan, sprinkle the nuts and sugar. Bake for 25 minutes in 175 degrees Celsius.

Simple as that :) Welcome home, mum, look what I made!
