So many commercial cookies in the US contain high fructose corn syrup and/or artificial colors, it makes sense to bake homemade cookies with simple wholesome ingredients. Kids love these chocolate-vanilla swirl cookies, and they are easy to make. They are definitely worth a try to give you the peace of mind to know exactly what your kids are eating! (By the way, parents like them too!)
You can find the recipe in French here. I recommend preparing the dough the evening before and letting it rest in the refrigerator overnight. That way, the next day, you just have to slice the dough, and stick the cookies in the oven!
