Ingredients
- 1 cup creamy peanut butter
Creamy peanut butter serves as the primary flavor and texture component, providing rich, nutty notes that enhance the overall taste of the squares. - 1/2 cup granulated sugar
Granulated sugar adds sweetness and helps in achieving the perfect chewy texture that pairs beautifully with the rich peanut butter. - 2 cups mini marshmallows
Mini marshmallows not only contribute sweetness but also create a delightful chewy and gooey texture, encapsulating the essence of the treat. - 1 cup graham cracker crumbs
Graham cracker crumbs provide a subtle crunch and essential structure to the squares, offering a contrast to the creamy filling. - 1/4 cup unsalted butter
Unsalted butter adds moisture and richness to the mixture, helping to bind the ingredients together while enhancing the overall flavor. - 1/2 tsp vanilla extract
Vanilla extract amplifies the sweetness of the marshmallows and peanut butter, bringing a warm and aromatic quality to the squares.
Directions & Preparation
Step 1: Prepare the baking pan by lining it with parchment paper.
Lining your pan with parchment paper ensures the squares release easily after cooling. It also helps maintain an even thickness throughout, preventing any corners from burning and makes cleanup a breeze.
Step 2: In a mixing bowl, combine peanut butter and granulated sugar until smooth.
Mixing peanut butter with sugar creates a creamy base for the squares. This method ensures the ingredients are well integrated, leading to a consistent texture and flavor in each bite.
Step 3: Melt the butter over low heat, then add the mixture of peanut butter and sugar.
Melting the butter first allows it to blend seamlessly into the peanut butter mixture. Low heat prevents the sugars from caramelizing, ensuring a soft and chewy final product.
Step 4: Stir in the graham cracker crumbs and mix until fully combined.
Adding graham cracker crumbs at this stage helps to absorb moisture while adding structure. Mixing thoroughly ensures that all ingredients are evenly distributed, giving each square a consistent texture.
Step 5: Fold in the mini marshmallows gently.
Gently folding in marshmallows is crucial to maintain their integrity. This ensures they don't get completely melted, resulting in delightful pockets of chewy marshmallow in the final squares.
Step 6: Transfer the mixture into the prepared baking pan and press firmly.
Pressing the mixture uniformly into the pan creates an even surface and packs the ingredients tightly, which helps the squares hold their shape once cooled. Ensure you're pressing down firmly but not overly so to avoid crushing the marshmallows.
Step 7: Allow the squares to cool at room temperature for about an hour.
Allowing the squares to set at room temperature helps them firm up without being too soft. Once cool, cutting them into squares will result in cleaner edges and a more appealing presentation.
Step 8: Cut into squares and serve.
Cutting the squares after they have cooled is essential for keeping clean lines and surface. Use a sharp knife, and consider warming the blade slightly to make cutting easier, especially if the squares are very sticky.

Customize Your Marshmallow Squares
These Peanut Butter Marshmallow Squares are a fantastic canvas for experimentation. Consider adding chopped nuts for a delightful crunch or drizzling melted chocolate over the top for an indulgent twist. You can even fold in different flavors of marshmallows for extra fun in every bite.
Peanut Butter Alternatives
If you're looking to mix things up or have allergies to peanuts, alternatives like almond or sunbutter can be great substitutes. These nut butters provide a similar creamy texture and flavor, allowing you to enjoy this treat while accommodating dietary needs without sacrificing taste.

FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, crunchy peanut butter will add texture, making the squares even more interesting to bite into.
What if my mixture is too thick?
If your mixture seems too thick to mix well, you can add a touch of melted butter or a bit more peanut butter to loosen it up.
Can I substitute honey for granulated sugar?
Yes, honey can be used, but adjust the amount to half since honey is sweeter. The texture may differ slightly.
What should I do if my squares are too sticky to cut?
If the squares are overly sticky, refrigerate them for about 20-30 minutes; this will help them firm up for easier cutting.
How do I add chocolate flavor to the squares?
You can melt chocolate and swirl it into the mixture or drizzle it on top once the squares have set.
What if I don’t have graham crackers?
If graham crackers are unavailable, you can substitute with digestive biscuits or any plain cookies that can be crushed into crumbs.
