I think it's OK but not 100%. I was advised to put the cinnamon on the flapjacks to make them more tasty but unfortunately nothing could do that for me. They're yuk. I think you're OK with doing that though.
Yeah Becky, me and my friend San have always put cinnamon in with a sweetener. Makes it yummy!
Officially we're not supposed to, but it's never slowed or stopped our losses.
