Chocolate Peanut Butter Kit Kat Crunch Bars

Chocolate Peanut Butter Kit Kat Crunch Bars feature a peanut butter and cereal base topped with a chocolate-peanut butter mixture layered with Kit Kat pieces and more cereal. The bars combine creamy peanut butter, crispy Rice Krispies, and the crunch of chocolate-coated Kit Kat pieces, delivering a mix of textures and flavors. Heating the peanut butter with sugars and corn syrup forms a sticky base, while the chocolate topping adds richness and crunch.

Instructions

    Cup of Yum
  1. Base – Line an 8-inch square pan with aluminum foil leaving overhang, spray with cooking spray; set aside.
  2. In a large microwave-safe bowl, combine peanut butter, corn syrup, sugars, and heat on high power for 1 minute to melt.
  3. Stop to stir. Mixture will be on the granular side, this is okay.
  4. Return bowl to microwave and heat for 1 more minute on high power.
  5. Stir in the vanilla.
  6. Stir in 3 cups cereal.
  7. Turn mixture out into prepared pan, packing it down somewhat firmly with a spatula and smoothing the top; set pan aside.
  8. Chocolate Topping – Dice the Kit Kats; set aside.
  9. In a medium microwave-safe bowl, combine chocolate chips, peanut butter, and heat on high power for 1 minute to melt.
  10. Stop to stir. Chips may not be completely melted. Return bowl to microwave and heat in 15-second bursts until chocolate can be stirred smooth, 15 seconds is likely all they’ll need.
  11. Stir in 1 cup cereal.
  12. Pour chocolate mixture over base, packing it down somewhat firmly with a spatula and smoothing the top.
  13. Place the Kit Kats in about 10 evenly and tightly spaced rows over the surface, with about 1/4-inch space between each piece (does not have to be perfect). By the time you get all the pieces on and in rows, the pieces you placed on first will likely have started to melt at the base. Push them down lightly so they embed into the chocolate-crispy layer. Go back over and push on all the pieces with your finger to ensure they’re all embedded and will stick as the bars cool and set up.
  14. Cover pan with a sheet of foil (to prevent fridge smells), and place pan in fridge to set up for at least 2 to 3 hours, or overnight, or until chocolate layer is completely set before lifting out with foil overhang, slicing, and serving.
  15. Bars will keep airtight at room temperature for up to 1 week, in the refrigerator for up to 2 weeks, or in the freezer for up to 6 months.
