Peanut Butter Chocolate Chip Bars will melt in your mouth with their buttery crisp edges and soft and chewy center. Loaded with crunchy Reese's Pieces and gooey chocolate chips, each bite is peanut butter chocolate bliss. These easy to make, decadent and dreamy cookie bars are perfect for get togethers, potlucks, or just because 😉.
Is there anything better than a gooey, moist and chewy cookie bar?
Once you try these peanut butter and chocolate chip bars, I think you will agree with me that there's nothing better. NOTHING!
These wonderfully buttery, sinfully rich bars are a chocolate peanut butter lover's dream. With Reese's Pieces and gooey chocolate chips, each scrumptious bite is pure joy.
But I must warn you: these oh-so-tasty bars are a little dangerous. They are seriously addictive. So soft and satisfying, with melt in your mouth decadence, it's really hard to eat just one (or two)!
This tasty recipe was inspired by my Mini Egg Cookie Bars--a buttery, chocolaty spring time hit, and Peanut Butter Butterscotch Blondies.

👪Why you'll love it
| Winning flavor combo- anyone who loves chocolate and peanut butter together will instantly crave these gooey cookie bars, that are loaded with Reese's Pieces and chocolate chips! Easy recipe- these cookie bars are made from scratch, but they are incredibly easy to whip together and use basic ingredients that you most likely already have on hand. Great cookie taste without the hassle- when you make cookie bars, the entire batter goes into the pan and bakes as one! No scooping or multiple pans needed! |
🥘Ingredients
- butter- the key to creamy, melt in your mouth, cookie bars
- brown sugar- firmly pack it for best results; you can use light or dark brown
- eggs- room temperature eggs are best because they mix better with the ingredients
- pure vanilla extract- this is much richer and more flavorful that imitation vanilla extract
- all-purpose flour- gently spoon into your measuring cup and then level it with a knife for best results
- baking powder & salt- leavening agents to make these dense cookie bars rise ever so slightly
- Reese's Pieces & chocolate chips- you may choose to save a few to press into the top before baking
See recipe card for quantities.
🔪Instructions
- Step 1: Melt the butter, then mix with the brown sugar, eggs, and vanilla.
- Step 2: Mix the dry ingredients in a separate bowl; then add to butter mixture bowl. Stir until just combined.
- Step 3: Stir in Reese's Pieces and chocolate chips until just combined.
- Step 4: Bake in a 13x9 pan for 20-22 minutes. Allow to cool slightly before cutting into squares.
Hint: Stir until JUST COMBINED (it's okay if the batter is a little lumpy). If you over stir, it will become too cake-like.
📖Variations
- M&M's reverse- Use M&M's and peanut butter chips instead for a candy flavor reversal!
- With nuts- add ½ crushed walnuts to the batter when you add the candy.

💭Top tip
I generally bake these for 20-22 minutes. Keep in mind that the longer cookie bars bake, the more cake-like they will be. The less they bake, the more they will resemble a blondie (but of course, bake them long enough so that they're not too ooey gooey and are safe to eat). As a general rule of thumb, you want the tops and edges to be golden brown and buttery crisp, with a soft and chewy, dense center.
Always use a metal, non-stick pan for cookie bar recipes.
