  1. First off I think this was meant to be... I was in the grocery store a few days ago and threw chocolate chips, peanut butter chips, and marshmallow cream into the cart with no plan other than thinking "I'll just google a recipe when I get home". I love your site so I ended up coming straight here first before resorting to Google. Anyway... can't believe this recent post of yours fit my needs so perfectly! I made them with marshmallow cream instead of marshmallows, turned out fantastically, stamp of approval from my sons! Also, side note... wonder if perhaps you didn't mean to include the addition of vanilla in both step 2 and step 3? I added it in step 2, seemed like the right place at the right time :) Thank you for all of your delicious recipes, my all-time favorite is your "Avocado Chicken Enchilada" recipe... ALWAYS a crowd pleaser! Keep on keepin on Sisters!
