"Create 3 cookie recipe variations using Whittakers Creamy Caramel Chocolate and/or Ferrero Rocher Easter Eggs. The user prefers a higher butter-to-flour ratio and a chewy texture, and sometimes uses some bread flour for chew. Include one recipe with Whittakers chocolate mixed in, one with Whittakers chocolate stuffed into the cookies, and one with Ferrero Rocher Easter Eggs mixed in or stuffed in. Address the concern that caramel filling may affect baking by recommending whether to mix in, stuff, chill, or freeze the chocolate pieces, and note any adjustments needed to prevent leakage or spreading. Use metric units only. Make the recipes practical, accurate, and bakery-style chewy."
