Ingredients You'll Need
This Peanut Butter Marshmallow Squares Recipe calls for just a handful of ingredients, but each one plays a key role in building that irresistible flavor and texture. From the buttery base to the sweet marshmallows, everything comes together effortlessly to create a perfect balance of creamy, chewy, and sweet notes.
- Butter (½ cup or 1 stick): This adds richness and helps bind the squares together with a smooth, luscious base.
- Butterscotch chips (1 11 oz. bag): Their caramel-like sweetness enhances the peanut butter and adds a warm, inviting flavor.
- Peanut butter (1 cup, creamy or crunchy): The star ingredient, bringing nutty flavor and creamy texture that pairs amazingly with the marshmallows.
- Mini marshmallows (1 16 oz. bag): They deliver the fluffy, gooey chewiness that makes these squares fun and delightfully indulgent.
How to Make Peanut Butter Marshmallow Squares Recipe
Step 1: Chill the Marshmallows
Start by placing the bag of mini marshmallows in the freezer for about 15 to 20 minutes. This little trick helps keep them from melting too fast when combined with the warm peanut butter mixture, ensuring they hold their shape and give you that perfect chewy texture in the squares.
Step 2: Prepare Your Pan
Line a 9x13 inch baking pan with parchment paper. This makes it super easy to lift the whole batch out once chilled and also simplifies clean-up. Having the lines smooth and ready will save you time and frustration later on.
Step 3: Melt the Butter, Butterscotch, and Peanut Butter
In a medium saucepan set over medium-low heat, combine the butter, butterscotch chips, and peanut butter. Stir constantly until everything melts together into a silky, creamy sauce. Be careful not to let it boil. This mixture is the glue that holds your marshmallows together and infuses every bite with rich, sweet flavor.
Step 4: Mix in the Chilled Marshmallows
Pour the cold mini marshmallows into a large mixing bowl. Then, quickly pour the warm peanut butter and butterscotch mixture over them. Stir everything together gently but thoroughly, making sure every marshmallow is coated with that luscious sauce.
Step 5: Transfer to the Pan and Chill
Pour the sticky mixture into the parchment-lined pan. Use a rubber spatula to pat and spread the mixture out evenly, pressing gently so the squares will hold their shape after chilling. Cover the pan and pop it into the refrigerator for 1 to 2 hours until the dessert is firm and ready to cut.
Step 6: Cut and Serve
Once set, lift the whole batch out using the parchment paper edges and place it on a cutting board. Cut into 24 equal squares and get ready to enjoy every gooey, sweet bite. These bars store beautifully and make a fantastic snack or dessert anytime.
How to Serve Peanut Butter Marshmallow Squares Recipe
Garnishes
While these squares are delicious on their own, a sprinkle of crushed peanuts or a drizzle of melted chocolate adds a lovely texture and enhances the peanut butter flavor. You could even add a dusting of cocoa powder for a subtle twist.
Side Dishes
Pair these squares with a cold glass of milk or a warm cup of coffee or tea. They also work well alongside fresh fruit slices or a scoop of vanilla ice cream for an extra special dessert spread.
Creative Ways to Present
For a festive touch, serve the squares on a decorative platter lined with colorful parchment paper. Wrap individual squares in parchment for gift-giving, or stack them in mason jars for a charming edible gift. You could even layer them into a parfait glass with whipped cream for a fun dessert presentation.
Make Ahead and Storage
Storing Leftovers
Once cut, store your Peanut Butter Marshmallow Squares Recipe in an airtight container at room temperature for up to 3 days. If your kitchen is warm, the fridge works well too, helping them keep their shape and texture.
Freezing
These squares freeze beautifully! Wrap individual pieces tightly with plastic wrap and place them in a freezer-safe bag or container. They’ll keep for up to 2 months. Just thaw at room temperature when you’re ready to enjoy.
Reheating
If you prefer a warm treat, microwave a square for about 10 seconds to soften it up without losing the chewy texture. Avoid overheating as it could melt the marshmallows entirely and change the texture.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter adds a nice bit of texture that contrasts wonderfully with the soft marshmallows. Both types work well, so use your favorite or whatever you have on hand.
Can I substitute butterscotch chips with something else?
If you don’t have butterscotch chips, white chocolate chips or even regular chocolate chips can be great alternatives. They’ll add a different flavor dimension but keep the bars just as delicious.
Is it possible to make these squares without butter?
Butter adds crucial richness and helps with the texture, so it’s best not to skip it. However, you might experiment with margarine or coconut oil, but expect slight changes in flavor and firmness.
Are mini marshmallows necessary, or can I use large marshmallows?
Mini marshmallows work best for even mixing and a balanced texture. If you only have large marshmallows, chop them into smaller pieces before freezing and mixing to get a similar effect.
How long will the Peanut Butter Marshmallow Squares Recipe stay fresh?
Stored properly, these squares remain fresh for about 3 to 5 days at room temperature or refrigerated. Freezing extends their life up to 2 months while preserving great taste and texture.
