You don’t HAVE to brown the butter but it does add a nice nutty and cozy flavor to the apples and caramel.
By dividing the marshmallows and adding a couple of cups of them in at the end it means that they hold their shape and you get little pockets of marshmallows in the treats. However, you can omit the extra 2 cups of marshmallows, if desired. But DO NOT melt them in or you will get a thick marshmallow layer that settles in the bottom of the pan and treats.
You can sprinkle more marshmallows and caramel bits on the top before pressing down for a prettier presentation.
You can use aluminum foil instead of parchment paper but it is very important that you spray the aluminum foil with nonstick spray, otherwise the treats will stick to it.
I get my freeze dried apples at Target and I know Trader Joe’s carries them too. You can also buy them on Amazon, but the Amazon ones are almost double the price. You can use a 1 - 1.5 ounce bag for this recipe.
Store in an airtight container at room temperature for 2 days or freeze for up to 6 months.
