Prepare a 13"x 9" pan. By lining the pan with parchment paper & spraying the paper with butter.

In a large bowl, mix the following: kahlua, sugar, & 1 stick melted butter together until smooth. Then, set aside to cool.

Use a double boiler by adding water in a sauce pan but only about 3-4 fingers high. Bring that water to a soft rolling boil. Then, add a large metal bowl on top of the sauce pan without the bowl touching the water.

Once your double boiler is built & ready, add the following into the bowl: chocolate chips, & 4 Tbs butter. Slowly melt until smooth. Remove from double boiler & let chocolate cool.

Pour the kahlua mixture into your prepared 13"x 9" pan, then pour your cooled chocolate layer on top of your kahlua layer. Freeze until set.
