The addition of brown butter to these Brown Butter Rice Krispie Treats takes them to a whole new level! Just a couple extra minutes of efforts makes for huge flavor.
In a heavy bottom pan, melt butter and stir until it begins to foam and turn golden brown. Stir constantly. It can go from browned to burned very quickly.
Add in marshmallows and stir until marshmallows melt. Add in half of the salt and vanilla.
Put cereal in a large bowl. Pour marshmallow mixture over the top and stir to combine and totally coat cereal.
Place mixture into a greased or parchment lined 9 x 13 pan. Lightly push into pan.
Sprinkle with remaining salt and allow to cool and set up.
