Creating your Brown Butter Dulce de Leche Rice Krispie Treats is a simple process. Follow these straightforward steps:

1. Prepare the Pan: Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy removal later. Lightly grease the parchment with cooking spray.
2. Brown the Butter: In a large saucepan, melt the butter over medium heat. Continue cooking, stirring frequently, until it turns a golden brown and releases a nutty aroma. This should take about 5-7 minutes. Be careful not to burn it.
3. Add Marshmallows: Once the butter is browned, immediately add the marshmallows to the pan. Stir continuously until the marshmallows are fully melted.
4. Mix in Dulce de Leche: Remove the pan from the heat and stir in the dulce de leche, vanilla extract, and a pinch of salt. Mix until everything is well combined and smooth.
5. Combine with Rice Krispies: Gently fold in the Rice Krispies cereal until evenly coated with the marshmallow mixture. Be careful not to crush the cereal.
6. Transfer to Pan: Pour the mixture into the prepared baking dish. Use a greased spatula or your hands to gently press the mixture into an even layer. Make sure it’s packed down but not overly squished.
7. Cool the Treats: Allow the treats to cool at room temperature for about 30 minutes. You can also place them in the refrigerator to speed up the cooling process.
8. Slice and Serve: Once cooled, lift the treats out of the pan using the parchment overhang. Slice them into squares or rectangles based on your preference.

If you want an extra touch, drizzle melted chocolate over the top before slicing.
