How do I count Rhubarb Crumble?

Hi all, my mom made me a rhubarb crumble made with sweetner not sugar. I think its the SW crumble.

How do I count this?

Today I have had...

Bran Flakes, Banana, Cous Cous, Yogurt, Rice and steak for tea.

Thanks all xx Lucie

Anyone please? I am worrying how many sins i had

Rhubarb, stewed without sugar, 198g; 0.5
And then the topping, well depending how much you had...and what the topping was made with (butter, flour, sugar etc.) will add up.
