Yes! Making these treats in the microwave is a great alternative to the stove top method if you are short on time. Here's what you do... - In a microwave safe large bowl, heat your butter, caramel and marshmallows on high for 3 minutes, stirring after each minute. - Stir in vanilla and Rice Krispies until well coated with the caramel/marshmallow mixture. - Using a lightly buttered spatula (or the cold spoon method we mentioned above), press mixture into a 9x13" pan so it's an even layer. - Allow to cool slightly then cut into squares.
