Disappearing Marshmallow Bars
Deliciously gooey marshmallow bars with chocolate and butterscotch flavors, perfect for sharing at parties or as a sweet treat for family gatherings.
Ingredients
Instructions
- Melt butterscotch chips and butter in a 3-quart saucepan over medium heat, stirring constantly.
- Remove from heat and cool to lukewarm.
- Add flour, brown sugar, baking powder, salt, vanilla, and eggs to the mixture.
- Mix well until combined.
- Add the mini marshmallows, chocolate chips, and chopped nuts; mix with 5 strokes.
- Spread the mixture in a greased 9 x 13-inch pan.
- Bake at 350°F (175°C) for 20 to 25 minutes.
- Do not overbake.
Tips & Substitutions
For a richer flavor, consider substituting half of the butterscotch chips with peanut butter chips. If you want a gluten-free option, use a 1:1 gluten-free baking flour instead of regular flour. Keep an eye on the baking time, as oven temperatures can vary; you want a golden brown top without overbaking. Adding a sprinkle of sea salt on top before baking enhances the flavor further.
Serving Suggestions
These Disappearing Marshmallow Bars are perfect for a sweet treat at parties or as an after-school snack. Serve them with a scoop of vanilla ice cream for an indulgent dessert, or pair them with a cup of coffee or tea for a cozy afternoon break. They also make a delightful addition to dessert trays alongside other treats like Grandma'S Fruit Snaps.

Frequently Asked Questions
Can I use different types of chocolate chips?
Absolutely! You can swap out semi-sweet chocolate chips for milk chocolate or dark chocolate chips, depending on your preference. This will change the flavor profile slightly, making it sweeter or more intense. Feel free to mix and match types for a fun variation.
What can I use instead of marshmallows?
If you prefer not to use marshmallows, you can substitute them with diced dried fruit, such as apricots or cherries, for a chewy texture. However, be aware that this will alter the taste and sweetness of the bars.
Can I freeze these bars?
Yes, these bars freeze well! To freeze, wrap them tightly in plastic wrap and then place them in a freezer-safe container. They can be stored in the freezer for up to 3 months. Thaw at room temperature before serving, or warm them slightly in the microwave for best results.
