As a food industry expert with a focus on product composition and labeling, I can provide you with a detailed answer regarding the ingredients of Kit Kat bars.

Kit Kat bars are a popular chocolate-covered wafer confectionery produced by Nestlé. The standard formula for Kit Kats does not typically include peanuts as an ingredient. The primary components are wafers, which are made from wheat flour, sugar, and cocoa, all coated with chocolate. However, it's important to note that there are variations of Kit Kats with different fillings, and some of these limited editions or regional specialties might contain ingredients like nuts.

For individuals with peanut allergies, it's crucial to check the packaging of any food product, including Kit Kat bars, for a list of ingredients and any allergen warnings. While the standard recipe does not contain peanuts, cross-contamination can occur in manufacturing facilities where peanuts or other allergens are processed, so an allergen warning might still be present.
