  1. Kathy, I am so sorry about that, you are right, I forgot to add the amounts for the top ingredients, so it’s updated now. These make 15-18 large and about 3 dozen small cookies, bake 7-8 minutes. Thank you so much for your feedback!! xoxo

  2. I was so confused when making these cookies. In the list of ingredients it states 3/4 cup chocolate chips.
    In the directions it has you putting the 3/4 cup in the mix, and later it directs you to melt the 3/4 cup of chips for drizzle over top. I decided to split the chips and use half in and half drizzled over.
    It would also be helpful to know how many cookies it made and if you could make smaller, more kid sized cookies and how long to bake a smaller size.

  3. Help! I believe you had a recipe for a Butterfinger Peanut Butter pie on here. I was traveling and couldn’t write it down. My son-in-law wants me to make it for his birthday Friday. I’m in trouble!!! Would it be possible for you to e-mail the recipe, please? I would sincerely appreciate it. I’m loving your recipe.

    Thanks.
