What makes these better than store-bought?

Homemade means control—you decide the sweetness, the chocolate thickness, and even the mix-ins (mini pretzels? Crushed peanuts? Do it!). Unlike prepackaged bars, these come without preservatives, and every bite feels a little more personal.

Ingredients & Easy Substitutions for Reese’s No-Bake Bars

Before we get into mixing and layering, let’s set the stage with your ingredients. Everything here is pantry-friendly and straightforward, but a few smart swaps can make the recipe suit just about any diet or craving.

What You’ll Need

• 1 cup unsalted butter, melted
  Helps bind the base and adds richness. For dairy-free, use melted coconut oil or vegan butter.
• 2 cups graham cracker crumbs
  This forms the crust. You can crush whole graham crackers in a food processor. For gluten-free, use GF graham-style crackers or crushed pretzels.
• 2 cups powdered sugar
  Adds sweetness and structure. Reduce to 1.5 cups for less sweetness, or use a sugar-free substitute like monk fruit powder.
• 1 cup creamy peanut butter (plus ¼ cup more for the topping)
  Shelf-stable brands like Jif or Skippy work best. Natural PB can work too but requires more chill time due to texture.
• 1½ cups semi-sweet chocolate chips
  Melt into that classic top layer. Try dark chocolate, white chocolate, or even butterscotch chips for variety.

Optional Add-Ins & Customization Ideas

• Chopped roasted peanuts for crunch
• Mini marshmallows for gooey texture
• Flaky sea salt on top
• A swirl of Nutella or cookie butter over the chocolate

Can I use almond or sunflower butter instead?

Absolutely. Almond butter gives a toasty flavor, while sunflower butter is great for nut-free versions. You might need to tweak the graham cracker ratio for ideal firmness.

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

No oven. No fancy tools. Just a few bowls, a microwave, and a fridge. You’re about 15 minutes away from a tray of rich, chocolatey peanut butter bars that taste like they came from a candy shop.

Step 1: Make the Base

In a medium bowl, combine:

• 1 cup melted butter
• 2 cups graham cracker crumbs
• 2 cups powdered sugar
• 1 cup creamy peanut butter

Mix until smooth and thick—like soft cookie dough.

Step 2: Press Into the Pan

Grease or line a 9×13-inch baking pan. Press the mixture evenly into the bottom using a spoon or your palm.

Step 3: Make the Chocolate Layer

In a microwave-safe bowl, mix:

• 1½ cups chocolate chips
• ¼ cup creamy peanut butter

Microwave in 30-second bursts, stirring each time until glossy and pourable.

Step 4: Spread and Chill

Pour the melted chocolate mixture over the base and smooth it out. Refrigerate for 2+ hours until fully set. Cut into bars or squares and enjoy!
