Step-by-Step Instructions
Here’s how to make peanut butter marshmallow squares in just a few simple steps.
Step 1: Prep Your Baking Pan
- Line your 9×13-inch baking pan with parchment paper, ensuring the edges hang over the sides for easy lifting later.
Step 2: Melt the Peanut Butter & Butter
- Grab a saucepan and melt the unsalted butter over medium-low heat. Once melted, stir in your creamy peanut butter until the mixture is completely smooth.
- Remove from heat and stir in the vanilla extract for a touch of aroma.
Step 3: Combine with Powdered Sugar
- Gradually sift the powdered sugar into the warm mixture, stirring continuously to make a smooth, thick batter.
Step 4: Fold in the Marshmallows
- Set aside a small handful of marshmallows for garnish (if desired). Then, fold the rest into the peanut butter mixture using a spatula, ensuring they’re evenly coated but not melted.
Step 5: Transfer & Spread
- Pour the mixture into your prepared baking pan and gently press it down using the spatula until you have an even layer.
Step 6: Chill and Slice
- Refrigerate for at least 2 hours or until the squares are firm. Once set, lift the parchment paper out of the pan and use a sharp knife to cut into squares. Pro Tip: Grease your knife lightly with butter to avoid sticking!
Tips & Tricks for Perfect Peanut Butter Marshmallow Squares
- Don’t Overheat the Marshmallows: Mix the marshmallows off-heat to prevent melting entirely. You want them to stay fluffy for that classic texture.
- Use a Large Mixing Bowl: This makes it easier to fold everything together without spillage or uneven mixing.
- Grease Your Tools: Lightly coat your spatula and knife with non-stick spray or butter to handle the sticky mixture effortlessly.
- Experiment with Layers: For a more decadent dessert, layer the peanut butter mixture with a thin layer of chocolate (melted and cooled slightly) before chilling.
Variations to Try
One of the best things about this recipe? It’s endlessly customizable! Here are some fun ideas to switch up the flavor profile:
- Chocolate Chunk: Add semi-sweet or dark chocolate chunks to the mixture for a richer taste.
- Salted Caramel: Once the squares are set, drizzle with salted caramel and a pinch of flaky sea salt for a sweet and savory kick.
- Nutty Delight: Mix in chopped peanuts, almonds, or pecans to add extra crunch and nuttiness.
- Cookie Butter Swirl: Stir in dollops of cookie butter before spreading the mixture into the pan for a dessert mashup like no other.
- Cinnamon Spice: Add 1 teaspoon of cinnamon to the mixture for a cozy, spiced twist. Perfect for fall gatherings!
How to Store Peanut Butter Marshmallow Squares
To keep your squares tasting fresh, follow these storage tips:
- Refrigerator: Store the squares in an airtight container in the fridge for up to a week. Place parchment paper between each layer to prevent sticking.
- Freezer: For longer storage, freeze them in a freezer-safe container for up to 3 months. Leave them to thaw at room temperature before serving.
