Toasted Marshmallow Rice Krispies Treats

Ingredients

• 5 1/2 cups Rice Krispies cereal
• 1 (10-ounce bag) large marshmallows
• 1/2 cup (1 stick) salted Kerrygold butter, sliced into 8 pieces
• 1 teaspoon vanilla extract
• Flaked sea salt, for topping (optional)

Instructions

1. TOAST: Position a rack in the center of the oven and preheat the oven to 450ºF.

2. Line two baking sheets with foil.

3. Pop the Rice Krispies on one baking sheet and spray the other foil-lined baking sheet with cooking spray.

4. Place the marshmallows in a single layer on the baking sheet with cooking spray.

5. Place the Rice Krispies in the oven when the oven has preheated and bake the cereal for 3-5 minutes, stirring every 45-60 seconds so that they don’t burn. They're done when they're a deeper golden and smell toasted.

6. BROIL: While the cereal is roasting, spray a square (8x8 or 9x9) baking dish with cooking spray; set aside for now.

7. Remove the Rice Krispies from the oven and allow them to cool on the baking sheet for 5 minutes.

8. Flip the oven to the broil setting.

9. Place the marshmallows in the oven (on the same center rack, do not move the rack up) for 30-60 seconds or until golden brown and toasted on top.

10. Keep a close eye on them; they go from toasty to burnt very quickly!

11. Remove marshmallows from the oven and let cool while you prepare the brown butter.

12. BROWN BUTTER: Place the butter in a large steel pot (or light bottomed cast iron) and allow it to melt over medium heat.

13. Once the butter melts, it'll start to foam.

14. Continue stirring and cooking the butter for 5-7 minutes or until it turns golden brown.

15. DO NOT WALK WAY and keep stirring.

16. It will smell all nutty and toasty when done.

17. Then lower the heat to the lowest setting, add the marshmallows and continue cooking until the marshmallows melt down, stirring frequently with a rubber spatula.

18. Season with the vanilla extract.

19. Stir to combine.

20. Then add the Rice Krispies to the pan.

21. With the heat on the lowest setting, continue to stir until all the Rice Krispies are evenly coated in the marshmallow mixture.

22. TREATS: Working quickly at this point, dump the prepared treats into the baking dish.

23. Spray the back of a glass or steel measuring cup with cooking spray and use this to gently press the Rice Krispies down into an even, flat layer inside the baking dish.

24. FINISH: Sprinkle with flaked sea salt, if desired.

25. Then, let cool completely until set.

26. Using the parchment overhang, grab the parchment paper, lift out, and cut into squares.

27. Store any leftovers in an airtight container.
