What You Need for This No-Bake Reese’s Peanut Butter Bars

• 1 cup (225g) Unsalted butter, melted
• 2 cups Graham cracker crumbs (finely crushed)
• 2 cups Powdered sugar
• 1 ½ cups Creamy peanut butter (divided)
• 1 ½ cups Semi-sweet chocolate chips

Chef Sophie’s Substitution Tip: If you want a deeper, more “adult” flavor, swap the semi-sweet chips for dark chocolate (60% cocoa) and add a tiny pinch of flaky sea salt on top!

How to Make No-Bake Reese’s Peanut Butter Bars (Step-by-Step)

1. Prepare your pan by lining an 8×8 inch square baking dish with parchment paper, leaving a little overhang on the sides so you can easily lift the bars out later.
2. Mix the melted butter, graham cracker crumbs, and powdered sugar in a large bowl. Stir in 1 cup of the creamy peanut butter until the mixture is thick and well combined.
3. Press the peanut butter mixture firmly into the bottom of your prepared pan. Use the back of a spoon or a flat measuring cup to smooth it into an even, level layer.
4. Melt the chocolate chips and the remaining ½ cup of peanut butter together. You can do this in the microwave in 30-second bursts, stirring in between until the glaze is glossy and completely liquid.
5. Spread the chocolate glaze over the peanut butter base using an offset spatula to ensure it reaches every corner.
6. Chill the bars in the refrigerator for at least 2 hours, or until the chocolate is firm and set.
7. Slice into squares using a warm knife for the cleanest, most professional-looking edges.

Chef Sophie’s Pro-Tips for the Best No-Bake Reese’s Peanut Butter Bars

• The “Warm Knife” Trick: For those sharp, bakery-style edges, run your knife under hot water and wipe it dry between every single cut. It melts through the chocolate layer like butter!
• Don’t Use “Natural” Peanut Butter: For this specific recipe, stick to traditional creamy brands (like Jif or Skippy). The oils in natural peanut butter can be too thin, preventing the bars from setting properly at room temperature.
• Sift Your Sugar: To ensure a velvety mouthfeel, sift your powdered sugar before mixing. It prevents those tiny white lumps from appearing in your peanut butter base.

How to Serve Your No-Bake Reese’s Peanut Butter Bars

• Classic Platter: Stack them in a pyramid on a white ceramic plate for a clean, modern look that highlights the distinct layers.
• The Sundae Topper: Chop up a few bars into smaller chunks and use them as a decadent topping for high-quality vanilla bean ice cream.
• Coffee Pairing: Serve these chilled alongside a bitter espresso or a dark roast coffee to cut through the beautiful sweetness of the chocolate.
