Unwrap butter and place in 13" x 9" pan. Place pan, with butter, in the oven and turn the oven on to 350*F. Butter can melt in pan while preheating. Keep an eye on it, checking every few minutes and pulling out of the oven when butter is melted. Please be careful while preparing recipe as pan will be very hot.

Crush graham cracker and pretzels in food processor to crush into a fine crumb. Set aside.

Mix sweetened condensed milk and dulce de leche in a microwave safe bowl. Microwave for ten seconds, remove, stir and microwave for another 10 seconds if needed. You'll want the two to combine and be a pourable consistency.

When butter is melted, remove from oven and carefully sprinkle the graham cracker and pretzel crumbs over the melted butter. Press in lightly with fork or back of spoon.

Pour sweetened condensed milk & dulce de leche mixture over crumb layer.

Sprinkle 1/2 of the chocolate chips, nuts, 1/2 of the Kraft caramel bits and broken up pretzels over sweetened condensed milk layer.

Following the directions of the back of the Kraft Caramel Bits, melt bits with small amount of water then drizzle over top of bars. Allow bars to cool completely.

Cut, serve, share, enjoy!
