Thank you for your comment. Heating honey in normal cooking or baking conditions will not turn honey into poison or make it harmful to consume.
Some nutrients can be destroyed in foods when cooking or baking so if you were using raw honey, the main concern would be loss of beneficial enzymes and antioxidants, not the formation of toxins.
I do believe honey is actually quite sensitive to heat. So if the recipe is no-bake maybe this works but it won’t work in a baking recipe, over 140 degrees F it makes it toxic even potentially, wasteful, especially if you’re using real honey that’s packed full of nutrients.
