How to Make Peanut Butter Marshmallow Squares

Now that we’ve got our ingredients ready, let’s dive into making these delightful Peanut Butter Marshmallow Squares. This process is simple, quick, and oh-so-rewarding! Let’s break it down step by step.

Step 1: Melt the Butter

Start by grabbing a large saucepan and placing it on low heat. Add in your unsalted butter, allowing it to melt slowly.

Keep an eye on it, stirring gently every so often. This helps prevent burning, which can ruin your delicious squares. You’ll know it’s ready when it’s completely melted and the surface looks shiny.

Be patient—rushing this step can lead to scorched butter. Remember, the key to a smooth texture starts right here!

Step 2: Add Peanut Butter and Butterscotch Chips

Once your butter is all melted, it’s time to add in the creamy peanut butter and butterscotch chips. At this point, stir consistently to combine everything thoroughly.

Focus on getting a smooth mixture without any lumps. The mesmerizing swirl of peanut butter and butterscotch is a great motivator!

By incorporating these ingredients properly, you create a luscious foundation that brings the peanut butter flavor to life. This is where the magic truly begins, folks!

Step 3: Stir in Vanilla Extract

Now, remove that lovely mixture from the heat and add in a teaspoon of vanilla extract.

While it might seem like a small addition, it makes a world of difference. Vanilla enhances the flavor, giving it a warm and inviting essence.

Just stir it in until it’s evenly distributed, and you’ll immediately notice the aroma. Vanilla is like a hug for your taste buds, wrapping them in cozy goodness!

Step 4: Fold in Marshmallows

Here comes the fun part! Grab those fruity mini marshmallows and gently fold them into your mixture. Make sure they’re evenly coated with that luscious peanut butter and butterscotch.

This step is a great opportunity to involve your kids—they’ll love helping out! Just be careful not to crush the marshmallows while folding.

This blend creates delightful pockets of chewy sweetness that make every bite a tasty adventure!

Step 5: Transfer and Press Mixture

Next, it’s time to transfer your delicious mixture into a greased 9×13-inch baking dish.

I find using a spatula works wonders to avoid sticking and helps spread the mixture evenly.

Once it’s in the dish, press it down gently to form an even layer. Don’t skip this step—it helps the squares hold together beautifully when cut. You’ll want to achieve that perfect thickness, ready for the next tasty stages!

Step 6: Set the Squares

Now, let your masterpiece sit at room temperature for at least two hours, or pop it into the refrigerator for a quicker set.

Waiting is the hardest part, but it’s worth it! Check for firmness before slicing; it should be set but still chewy. The longer you let it set, the better the texture.

This patience yields rich flavors and perfect squares, ready to delight your family!

Step 7: Cut and Serve

With your squares now set, it’s time for the delicious moment we’ve all been waiting for! Use a sharp knife to cut them into squares—aim for about 1.5 inches for perfect portions.

Transfer those tasty squares to a serving platter or keep them in the dish. Don’t forget to offer them with a glass of cold milk or a cup of tea for a delightful snack!

Each square is a treasure of flavor and sweetness, ready to make your loved ones smile!

Tips for Success

Always measure your ingredients accurately for the best results.
Let the butter melt slowly; this preserves its flavor.
Use a clean spatula for transferring the mixture to avoid sticking.
Refrigerate longer if you prefer firmer squares.
