Ingredients
Wet Ingredients
- ½ cup creamy peanut butter
- ½ cup unsalted butter, softened
- ¾ cup white (granulated) sugar
- ¾ cup light brown sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
Dry Ingredients
- 2 ¼ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
Mix-Ins
- 1 cup peanut butter chips
- 1–2 cups semi-sweet chocolate chips
(Use 2 cups for ultra-sweet, chocolate-loaded bars) - Optional but amazing: chopped Reese’s peanut butter cups
Instructions
- Preheat the Oven
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking pan or line with parchment paper. - Cream the Butter & Peanut Butter
In a large mixing bowl, beat the softened butter and peanut butter until smooth, fluffy, and creamy. - Add Sugars
Add white sugar and brown sugar. Mix until just combined—do not overmix. - Add Eggs & Vanilla
Add eggs and vanilla extract. Mix gently until incorporated. - Combine Dry Ingredients
In a separate bowl, whisk together flour, baking powder, and salt. - Mix Dough
Slowly add dry ingredients to the wet mixture, mixing just until combined. - Fold in the Good Stuff
Gently fold in peanut butter chips, chocolate chips, and Reese’s if using. - Bake
Press dough evenly into the prepared pan. Bake for 25–30 minutes, or until edges are lightly golden and a toothpick inserted in the center comes out mostly clean. - Cool & Slice
Allow bars to cool completely before slicing. This helps them set and keeps them perfectly chewy.
Methods & Baking Tips
- Do not overbake – slightly underbaked centers = soft, chewy bars
- Room temperature eggs ensure smooth mixing
- Parchment paper makes lifting and slicing effortless
- Chill the bars slightly before cutting for clean edges
History
Peanut butter desserts became wildly popular in the U.S. in the early 1900s as peanut butter grew more affordable and accessible. Cookie bars emerged later as a convenient, crowd-friendly alternative to individual cookies—same flavor, less work. Adding chocolate chips (and Reese’s!) is a modern twist that turns a classic into a crave-worthy favorite.
Formation & Texture
These bars form in beautiful layers of flavor:
- A soft, dense peanut butter base
- Melty chocolate pockets throughout
- Golden edges with chewy centers
They slice cleanly but stay tender—perfect for stacking, gifting, or sneaking seconds.
