Easy Peanut Butter Blondies
Peanut butter blondies combine the rich and creamy flavor of peanut butter with the sweet and dense texture of traditional blondies! Loaded with peanut butter flavor and studded with Reese’s pieces these chewy treats are a favorite for peanut butter lovers!
This blondie dessert tastes like a mix between a classic blondie, M&M cookie bar and peanut butter bar. It’s got a great ratio of peanut butter and chocolate flavor and is the perfect texture with a soft middle and crisp edges. You’ll need a large glass of milk with these tasty bars. Perfection!
Best Type of Peanut Butter to Use
When making this recipe, it’s important to use creamy peanut butter, such as Jif or Skippy. A natural, drippy variety will not give you the same soft texture as the creamy type.
Baking Tips
- Line your baking dish with foil for easy removal.
- Make sure to accurately measure the flour with the spoon and level technique.
- Place extra Reese’s pieces on top prior to baking. This makes them look extra pretty.
- Don’t overbake! They may look a little soft, but they’ll harden as they cool.
- Use a toothpick to make sure the center of your peanut butter blondies comes out clean.
Variations
This recipe is super versatile, so feel free to make it your own. Swap Reese’s pieces for M&M’s, or use white or semi sweet chocolate chips in place of peanut butter chips. Chopped Reese’s cups are also an easy substitute for Reese’s pieces.
Or leave out the mix-in’s all together if you prefer. These peanut butter blondies are plenty chewy and delicious all on their own!
Can I Freeze Peanut Butter Blondies?
Yes, peanut butter blondies freeze very well. To freeze, simply wrap in foil and place in an airtight container or freezer bag. The blondie dessert will keep in the freezer for up to 3 months. When ready to enjoy, let thaw on the counter about an hour beforehand.
FAQs
Although they are both decadent and chewy dessert bars, they both have a totally different flavors. Brownies are made with chocolate and taste fudgy and rich, while blondies are made without chocolate and usually get their flavor from the brown sugar and vanilla (and peanut butter in this case).
Yes! The key to a perfect blondie is a gooey center. To achieve this texture, it’s important to remove the blondies from the oven when the edges are barely golden and the blondie is still soft in the center. They might look a little under done, but they’ll continue to set as they cool.
Over mixing the batter is the #1 culprit for blondies that have gone cakey. When too much air is incorporated into the mixture, this creates a light and fluffier texture similar to cake. So don’t get heavy handed with your batter. Mix the batter just until combined and then stop!

Mmmmmm, Brownies… and Peanut butter! Thanks for the recipe!
These look great, just what I was searching for!!! What is pictured on top of these and when did you add them??
Hi Meaghan! I just added extra M&Ms on top at the end right before baking! :)
I love your recipes! Just tried the blondie one, but confused w/the 2.5 cups in the recipe list and then the 1 cup in the directions. I used 2.5 cups and ended up w/blondie bread. Which isn’t a bad thing….
The directions say add 1 cup of flour and then in the next step it says add the rest…..
Hi Becky! You will be adding 2 1/2 cups of flour total, sorry for the confusion!
Hi Judy! Sorry for the confusion. It is 2.5 cups but it should be more of a brownie texture! Blondie bread would be yummy though! :)
