Since it’s such a small amount, this dish is considered to be safe for kids. Just like cupcakes and frostings with vanilla extract, most of the alcohol, if not all of it evaporates when it’s cooked or exposed to air.  If you want to be extra careful, I suggest cooking the mix for an extra 3 minutes over low heat (so it won’t boil) to cook off the alcohol completely. Note that the almond flavor may be less intense.
