    1. Spray your hands with non-stick cooking spray and gently press the mixture evenly into the pan. If you press too hard, you'll end up with hard marshmallow treats. Allow to cool for about 30 minutes before topping.

    Recipe Tips and Tricks

    • I was able to find a bag of Lucky Charms Just Marshmallows at Target. If you can't find them, I recommend buying a second box of Lucky Charms and picking the marshmallows out to decorate the top with.
    • If the candy melts begin to harden too quickly while swirling or topping with extra marshmallow and sanding sugar, pop the pan in a 300°F oven for a few minutes to melt again.

    Tips/Notes

    1. You can substitute regular unsalted butter.

    3. If the candy melts begin to harden too quickly while swirling or topping with extra marshmallow and sanding sugar, pop the pan in a 300°F oven for a few minutes to melt again.
