In a medium saucepan on a high heat melt the butter and sugar and add the greengages, cinnamon and the vanilla pod.
Simmer for four minutes on a low heat.
In a knickerbocker glory glass add some of the stewed greengages, then add a scoop of vanilla ice cream. Repeat this process until the glass is full.
To finish sprinkle the nuts, the chocolate and the oats on top.
