Preheat the oven to 350 degrees
In a large bowl, add the entire box of cake mix, plus the softened butter and 2/3 cup of the milk
Mix well
You can grease a 9x13 baking pan or use parchment paper to line it. Either way, pour about 1/2 of the Red Velvet mixture into the pan
Bake that for about 10 minutes
While that is baking, grab a saucepan and over medium to med/high heat, add the 1/3 cup of milk and the caramels. Stir often while the caramels melt, then when the caramel is all mixed into the milk and smooth, remove from heat
Pull the cake out of the oven
To the warm cake add the caramel mixture, chocolate chips, and pecans
Spread the remaining cake mix over everything
Bake for an additional 18 to 20 minutes
The cake mix will most likely still be a fudge brownie consistency and moist when done.
Allow to cool or serve up warm with ice cream and more caramel
