The sugar amount is within the WHO guidelines: - "In both adults and children, WHO recommends reducing the intake of free sugars to less than 10% of total energy intake (strong recommendation). • WHO suggests a further reduction of the intake of free sugars to below 5% of total energy intake (conditional recommendation). • Free sugars include monosaccharides and disaccharides added to foods and beverages by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates."
These recipes have less than 10% of calories from sugar, which is within their "strong recommendation (10%)" and close to their "hopeful" one (5%). Their 5% goal includes fruit eaten, so if you're replacing some fruit consumption with this, it could easily meet the health effects of the 5% goal.
To reduce sugar, you can replace half of it with the equivalent volume (not weight) of sucralose (Splenda). Tastes the same.
There's no health benefit to replace sugar with honey. In fact fructose (in honey and fruit) is the only sugar that appears to be less healthy than others. It produces uric adic which in large quantities forms crystals in your joints, the disease gout.
