Salted Peanut Marshmallow Bars are easy to make and tastes similar to Payday Candy Bars. Great for afternoon snacks and packing in lunches!
This is one of our favorite dessert recipes. It is pretty sweet, so a little goes a long way. They are perfect for packing into lunches or as an afternoon pick-me-up.
Salted Peanut Marshmallow Bars recipe is one of the few recipes that I make using box mixes. This is a holdover recipe from my beginner cook days.
This one is made with Yellow Cake Mix. Well, the crust layer is made with the mix with the addition of eggs and softened butter. I have never used another flavor for this recipe, but I suspect it would be perfectly fine to substitute another flavor. BUT, it probably won’t taste as close to a Payday Bar as one made with yellow cake mix.
Makes sure all of the edges of the pan are covered with parchment paper or a non-stick aluminum foil followed up with a baking spray to keep the marshmallows from turning into glue.
The mini marshmallows need to be ready to go as soon as the crust comes out of the oven. The residual heat will help the marshmallows melt. After adding the marshmallows, try to spread them out evenly. Move any marshmallows that are in piles and place them into areas that have the crust exposed.
Turn off the oven when the crust is done, you may need to place the crust topped with marshmallows back into the oven to ensure melting. By melting, I mean they will flatten slightly and become very soft. Much like marshmallows do when cooked on top of sweet potatoes.
While the marshmallows are melting, cook the topping. It is best to get the peanut topping added to the bars before the marshmallows get too cool.
The topping is best spread by placing spoonfuls around the pan. It will spread out a bit on its own. The salted peanut opping will need a bit of help and encouragement to completely cover the top. Keep gently nudging the filing with a small silicone spatula to fill in gaps with marshmallows peaking out.
If there are places with a peanut “pile-up” go ahead and separate them using 2 forks if necessary. It will look bad when you do this, but as the mixture cools, the uneven areas will smooth out. The photos in this post are of a pan of Salted Peanut Marshmallow Bars I manhandled. You can see in the close-up photo below that the top smoothed out on it own.
The edges with marshmallows peaking out can be cut off for cleaner edges. I do not do this because I am kind of lazy sometimes and I have never had anyone complain that there was a marshmallow bubble on their bar.
