Carmelitas

butter, melted (1 1/2 stick; I use unsalted butter but salted may be used)

/ 4 cup light brown sugar, packed

vanilla extract

all-purpose flour

whole-rolled old fashioned oats (not instant or quick cook)

baking soda

salt, optional and to taste

caramel squares, unwrapped (I used Werther’s Originals Baking Caramels which are slightly bigger than cellophane-wrapped caramels; if using those, I recommend using a couple more)

heavy cream

salt, optional and to taste, if you prefer salted caramel sauce

semi-sweet chocolate chips or chunks (I used a combo)
