To make these blondies, I started by pouring some light brown sugar into a large mixing bowl.
I added some melted butter to the bowl.
I also added some eggs, vanilla extract and salt to the bowl.
I stirred the ingredients together until smooth.
I added some smooth peanut butter to the bowl.
I also added some all purpose flour.
I stirred well again.
I added some mini Reese’s pieces candies, peanut butter baking chips and semi sweet chocolate chips to the bowl.
I stirred until all of the ingredients were incorporated into the blondie batter.
I lined a 9 x 13 inch baking pan with parchment paper.
I poured the batter into the parchment lined baking pan and spread it out evenly.
Then I sprinkled some more mini Reese’s pieces candies on top.
I placed the pan in the oven and baked the blondies until a toothpick inserted in the center came up with just a few crumbs.
I allowed the blondies to cool.
Then the blondies were ready to slice.
I chose to slice my blondies into 24 squares but you could cut them into smaller or larger bars if you prefer.
These blondies are dense, chewy, and packed with peanut butter flavor.
