Brown Butter Dulce de Leche Rice Krispie Treats

Spray a 9×9-inch pan with non-stick spray and line it with a foil or parchment paper sling.  Spray again.

Place a large pot on the stove over medium heat, add your butter and let it melt and then brown. *See notes below for browning butter.

Once the butter is browned, remove from the heat and add the salt and 8 cups of mini marshmallows. Stir until everything is completely melted and smooth. If you need to put it back on the heat to finish melting the marshmallows, that is fine. You just don’t want the browned butter to burn.

Once it is smooth, add vanilla and stir again.

Measure out the rice krispies cereal in a large bowl. Pour the melted marshmallows over the rice krispies and mix well.

Add in the remaining marshmallows while still warm.

Lightly press about half of the rice krispies mixture into your prepared pan (see note). Flatten it down so it is even in the pan and then spread the dulce de leche all over the rice krispies in an even layer.
