Ingredients Needed:

2 bags of chips (milk chocolate, peanut butter, mint chocolate, white chocolate, etc)
Vanilla extract
6 marshmallows (large or 24 miniature)
1 can of sweetened condensed milk (full fat, low fat or non-fat)
PAM cooking spray

Items Needed:
Microwave oven, [microwavable] mixing bowl & spatula, container or small aluminum foil pan

Optional:
Add 2 Tbsps peanut butter (if peanut butter chips are used)
Add 2 Tbsps Hershey's Chocolate Syrup (if milk chocolate or semi-sweet chocolate chips are used)

Directions:
Pour one bag of chips into bowl. Add 1 tsp of vanilla extract. Pour half of the can of sweetened condensed milk into bowl. Add 3 large marshmallows (cut up into pieces for easier melting) or 12 miniature marshmallows. (Add optional Tbsps of peanut butter now if using peanut butter chips - or optional Tbsps of Hershey's Syrup if using chocolate chips)

Stir to combine ingredients. Heat in microwave for ½ minute. Remove and stir with spatula. Return to microwave and heat another ½ minute. Remove and stir. Consistency should be smooth and silky, with all chips and marshmallows melted.

Exception: Peanut butter chips are coarser and will be more grainy in texture and appearance - and sets quicker. Work fast with this!

Caution:
Some older microwaves may require additional 30 seconds heating. Some newer microwave ovens may not require one full minute of heating, in order to melt ingredients. Gauge heating time by consistency of melted mixture.

When thoroughly melted, pour first layer into a lightly [Pam] sprayed container (dish, aluminum foil tray, etc). Smooth with spatula.

* Repeat next layer with choice of chips.

Chill for 30-minutes to an hour before attempting to cut into pieces. Will be more difficult to cut into pieces if completely chilled & set.
