I'm curious about making something chocolatey but want to keep it health-ish.

A recipe in front of me call for triple chocolate cookies, custard & margarine (Aust recipe too!). Which one of these would you replace? Comparing this one (a chocolate pear tart) vs the other (chocolate self saucing pudding) which one would be worse? There's 12g of fat, 22g of sugars & 257Cal in t he pear thing. 376 cal, 11g fat & 36g of sugar in the other.

I don't make treats very often as i have to then eat them. We would like to have a friend over at easter for a cool dinner & want one of these as a dessert.

I'm new to cooking
