Step 1

These instructions apply for any of the four varieties of Marshmallow Bars. First, line a 13- × 9-inch pan with parchment paper.

Step 2

Place the first three ingredients in a medium saucepan. Heat over medium heat, stirring frequently, until melted, combined and smooth.

Step 3

Remove from the heat and stir in the vanilla. Let cool until just warm, but not so hot as to melt the marshmallows in the next step.

Step 4

Place the remaining ingredients in a large bowl. Pour in the peanut butter mixture, stirring to coat completely.

Step 5

Pour into the prepared pan, spreading evenly. Refrigerate for 2 to 3 hours, then slice into 24 bars.

Step 6

Store in an airtight container in layers, with parchment or waxed paper between each layer, in the fridge for up to 5 days or in the freezer for up to 3 months.
