Equipment & Tools

Mixing bowls: For combining ingredients smoothly.
Measuring cups and spoons: To ensure precise ingredient amounts.
9×9 inch baking pan: Ideal size to form and chill the bars.

Cooking No-Bake Peanut Butter Bars: The Process

Step 1: Prepare Your Pan

Line your 9×9 inch baking pan with parchment paper, allowing some overhang on the sides. This helps you lift the bars out easily once set.

Step 2: Mix the Base Ingredients

In a large mixing bowl, combine the melted salted butter, powdered sugar, and brown sugar. Stir until the mixture is fully blended and smooth.

Step 3: Add the Crunch

Fold in the crushed graham crackers and 1 cup of creamy peanut butter. Mix thoroughly until all ingredients are evenly incorporated and the mixture holds together like a thick dough.

Step 4: Press Into the Pan

Transfer your peanut butter mixture into the prepared pan. Press it down firmly and evenly to create a solid base layer. A flat spatula or the back of a spoon works great for this.

Step 5: Make the Chocolate Peanut Butter Topping

In a microwave-safe bowl, combine the semi-sweet chocolate chips with 1/4 cup creamy peanut butter and 2 tablespoons peanut butter. Heat in short bursts (about 20-30 seconds), stirring in between, until the mixture is fully melted and smooth.

Step 6: Spread the Topping

Pour the melted chocolate and peanut butter mixture over the base layer. Use a spatula to spread it evenly, covering the entire surface.

Step 7: Chill and Set

Place the pan in the refrigerator for at least 2 hours, or until the bars are firm and fully set.

Step 8: Slice and Serve

Once set, use the parchment paper overhang to lift the bars from the pan. Cut into squares or rectangles, and enjoy your delicious No-Bake Peanut Butter Bars!

If You’re Out Of…

Powdered sugar: Substitute with a blend of granulated sugar ground finely in a food processor.
Graham crackers: Use digestive biscuits or any plain, crunchy cookie.
Semi-sweet chocolate chips: Swap with dark or milk chocolate chips based on preference.
Salted butter: Use unsalted butter plus a pinch of salt to balance flavors.

Troubleshooting Tips

Bars too crumbly: Make sure to press the base layer firmly and evenly. If still crumbly, add a tablespoon more melted butter or peanut butter.
Chocolate topping won’t melt smoothly: Melt in short bursts and stir frequently. Avoid overheating to prevent burning.
Topping too thick to spread: Add a teaspoon of vegetable oil or peanut oil to loosen the chocolate peanut butter mixture.
Bars too soft after chilling: Chill longer or place in the freezer for 15-20 minutes before slicing.

Freezer-Friendly Notes

No-Bake Peanut Butter Bars freeze beautifully, making them an excellent make-ahead option. After cutting into bars, place them in an airtight container with parchment paper layers to prevent sticking. Freeze for up to 3 months. When ready to enjoy, thaw in the refrigerator for a few hours or at room temperature for about 30 minutes.

Reader Q&A

Can I use crunchy peanut butter instead of creamy?

Absolutely! Using crunchy peanut butter will add an extra layer of texture to your bars, which many people enjoy. Just be sure to mix it well so the texture is evenly distributed throughout.

Is there a way to make these gluten-free?

Yes, simply substitute the graham crackers with gluten-free graham crackers or gluten-free digestive biscuits. This swap keeps the bars just as delicious while catering to gluten sensitivities.

How long do these bars keep at room temperature?

Since these bars contain butter and peanut butter, they’re best stored in the refrigerator and typically last about 4-5 days. At room temperature, they may soften too much after a few hours, especially in warm climates.

Can I double the recipe?

Definitely! Just double the ingredients and use a larger pan, or prepare two batches in separate pans. The preparation and chilling times remain the same.
