Two simple updates to well loved rice cereal treats change up the flavor in a sophisticated way: brown butter and sea salt. Delicously sweet, buttery and salty, these treats are easy to make and ready in less than an hour.
Line a 9-inch by 9-inch pan with foil allowing an overhang over each edge by at least 1 inch. Spray with non-stick spray.
In a large light-colored skillet melt the butter over medium heat, stirring often. Allow the butter to continue to cook until it turns deep golden brown, develops dark particles in the bottom, has a nutty aroma and is slightly foamy (about 3-4 minutes). Watch closely to avoid burning.
Add the marshmallows, vanilla extract and sea salt. Stir constantly, folding the marshmallows into the butter, until the marshmallows have fully melted (3-4 minutes).
Remove from heat and stir in the rice cereal, full coating it with the marshmallow mixture. Fold into the prepared pan and press down to compress. Allow to fully cool and cut into squares.
