Reese’s Peanut Butter Bars — Loaded with peanut butter, peanut butter cups and chocolate!! Soft, gooey and totally irresistible! Everything’s better with peanut butter cups!!
Peanut Butter Cup Bars
There’s no shortage of peanut butter recipes and peanut butter bars on my blog or in my first cookbook, Peanut Butter Comfort, with over 75 peanut butter recipes. But there’s always room for one more.
The bars are a spinoff of Peanut Butter Chocolate Chip Bars with the addition of peanut butter cups.
When I want an easy, fuss-free recipe that I know everyone will love, I call upon my trusty blondie base. With 30+ versions and counting, it never lets me down. It’s an easy recipe to memorize because everything is ‘one’. In the 1 bowl used, melt 1 stick of butter, stir in 1 egg, 1 cup of brown sugar, 1 tablespoon vanilla, and 1 cup flour.
For this version I added peanut butter, peanut butter cups, and chocolate chips.
The bars are super soft, slightly chewy, buttery, and have plenty of peanut butter flavor with enough chocolate to balance it. Between the butter, the peanut butter, and the peanut butter cups the bars are super moist and just melt in your mouth.
What’s in Reese’s Peanut Butter Bars?
To make these peanut butter cup bars, you’ll need:
- Unsalted butter
- Peanut butter
- Egg
- Light brown sugar
- Vanilla extract
- All-purpose flour
- Semi-sweet chocolate chips
- Min peanut butter cups
How to Make Reese’s Peanut Butter Bars
Whisk together the melted butter, peanut butter, egg, brown sugar, and vanilla. Stir in the dry ingredients, then fold in the chocolate chips.
Turn the batter into a greased 8×8-inch baking dish and top with peanut butter cups. Bake until done, then let cool for 1 hour before serving.
What Type of Peanut Butter Should I Use?
I use Jif, Skippy or a similar brand. Don’t use natural peanut butter as it can separate and/or be too oily.
Can I Double This Recipe?
Yes, you should be fine to double this recipe and bake it in a 9×13-inch pan.
Tips for Making Peanut Butter Cup Bars
I used semi-sweet chocolate chips, but you’re welcome to use milk or dark if desired.
For this recipe, you want to use mini peanut butter cups that come in wrappers. Don’t use the ones without wrappers that are labeled as “minis.”
These peanut butter chocolate chip bars are best fresh but will keep for up to 1 week in an airtight container at room temperature or up to 4 months in the freezer.

Peanut Butter Cup Peanut Butter Bars
Ingredients
- ½ cup unsalted butter, 1 stick, melted
- ⅓ heaping cup peanut butter, I use Jif, Skippy or similar; natural PB can separate and/or be too oily
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- ½ cup semi-sweet chocolate chips, plus more for sprinkling on top
- about 16 miniature peanut butter cups, unwrapped (not to be confused with the smallest size that come unwrapped called ‘minis’)
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- To a large, microwave-safe bowl add the butter and heat on high power to melt, about 1 minute.
- Wait momentarily before adding the egg so you don’t scramble it. Add the peanut butter, egg, brown sugar, vanilla, and whisk until smooth.
- Add the flour and stir until just combined, don’t overmix.
- Add 1/2 cup chocolate chips and stir to combine.
- Turn batter out into prepared pan, smoothing the top lightly with a spatula.
- Evenly distribute the peanut butter cups over the surface of the batter, pushing each cup down as far as it will go.
- Evenly sprinkle the surface with additional chocolate chips, about 1 tablespoon.
- Bake for about 22 to 25 minutes, or until done. If you can find a chocolate chip-free patch to test, a toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter.
- Allow bars to cool in pan for at least 1 hour before slicing and serving.
Notes
- Bars are best fresh but will keep for up to 1 week in an airtight container at room temp or up to 4 months in the freezer.
