Step 1

Prep a 9 by 13 pan by greasing it and/or lining it with parchment paper.

Step 2

Place marshmallows, butter and vanilla extract in a large microwave proof bowl and microwave until marshmallows are puffy and stir until smooth.

Step 3

Add Rice Krispie Cereal and fold until combined. Dump into prepared pan and pat until flat.

Step 4

Over medium heat melt unwrapped caramels, sweetened condensed milk, and butter until smooth. Pour over Rice Krispie Treats.

Step 5

Melt chocolate chips and spread over caramel. (Add a little cream if you want it to be thinner.)

Step 6

Sprinkle chopped pecans over the chocolate layer and let set in the fridge or on the counter. (But the fridge takes much less time.)
