Lightly grease a 9x13” pan.

Melt butter in a large non-stick saucepan over low heat.

Once melted, stir in the marshmallows until they are melted. Remove from heat.

Stir in the Lucky Charms cereal and stir quickly to coat.

Pour the mixture into the prepared pan and spread it evenly. Wet your hands to spread it evenly without it sticking to your fingers.

Quickly spread the remaining Lucky Charms marshmallows over the top and press them down.

Let the treats rest for about 2 hours and cut into squares to serve.
