In a large skillet over low heat, melt: butter and 10 oz marshmallows
Stir constantly until smooth and glossy. *Low heat = soft, gooey texture (not hard!)*
Stir in: chocolate chips, Cocoa powder, splash of cream and mix until melted and smooth.
Then add: vanilla and pinch of salt
Turn off heat and gently fold in the Cocoa Krispies plus ½ cups extra marshmallows.
Divide mixture evenly between two parchment-lined pans.
Lightly press into an even layer. *Don’t press too hard—this keeps them soft and chewy!
Let cool completely.
Remove one slab from the pan.
Spread an even layer of softened chocolate ice cream over the top.
Lift the second slab and place it on top and genly press to seal.
Freeze for 2–3 hours, until fully set.
Cut into squares or bars and serve.
