Super gooey Rice Krispie Treats with a filling of caramel and mini marshmallows!
Line 9 x 13 pan with nonstick foil, then spray lightly with non-stick cooking spray (these sticky bars need both!)
In a large microwave safe bowl, microwave the caramels, butter and condensed milk until melted and smooth when stirred.
In another large bowl, microwave half the butter and half the marshmallows ( 6 tablespoons butter and 4 cups marshmallows) just a minute and stir until melted. Stir in half the cereal (5 cups) and press evenly into the prepared pan.
Pour on the caramel and spread evenly. Sprinkle the top with the additional 2 cups marshmallows and freeze for 15 minutes.
Use the remaining butter, cereal and marshmallows and repeat the directions.
Press this layer on top of the marshmallows and caramel layer and return to the freezer for 15 minutes, then chill for a few more hours or overnight.
Cut into big squares to serve.
