How to Make Reese’s Pieces Cookie Bars

Step 1: Prepare the Batter

Preheat oven to 350°F (175°C).

Line a 9×13-inch baking pan with parchment paper.

In a large bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.

Beat in eggs one at a time, then add vanilla.

In a separate bowl, whisk flour, baking soda, and salt.

Gradually mix dry ingredients into wet ingredients until combined.

Fold in chocolate chips and Reese’s Pieces.

Step 2: Spread & Bake

Press dough evenly into prepared pan.

Sprinkle extra candies and chocolate chips on top if desired.

Bake for 25–30 minutes, until edges are golden and center is set but still soft.

Step 3: Cool & Slice

Allow bars to cool completely before slicing.

For extra clean cuts, chill for 30 minutes before cutting.

Expert Tips

Don’t Overbake

Bars will continue to set as they cool.

Use Room Temperature Butter

Ensures smooth creaming.

Slightly Underbake for Chewy Centers

Centers should look just set.

Press Extra Candies on Top

For a bakery-style look.

Flavor Variations

Double Peanut Butter

Add 1/2 cup peanut butter to the dough.

Chocolate Lover’s Version

Use milk chocolate chips instead of semi-sweet.

Stuffed Bars
