• Stir constantly until fully melted and smooth.

• Stir in vanilla extract and salt.

3. Combine with Cereal

• Remove from heat and add Rice Krispies cereal.

• Stir quickly until evenly coated with the brown butter marshmallow mixture.

4. Set and Serve

• Press mixture into a greased 9×13-inch pan or lined with parchment paper.

• Use a buttered spatula or parchment to flatten evenly.

• Let cool for at least 30 minutes before cutting into squares.
