Instructions
Peanut Butter Oat Bars
- Preheat your oven to 350°F.
- Mix together all ingredients (butter, peanut butter, white sugar, light brown sugar, salt, vanilla, eggs, flour, and oats) in a medium mixing bowl until well incorporated.1 cup salted butter, 1 cup creamy peanut butter, 1 cup granulated white sugar, 1 cup light brown sugar, 1 tsp salt, 1 tbsp vanilla extract, 2 large eggs, 2 cups all-purpose flour, 1½ cups old-fashioned oats
- Pat the oat bar mixture into a 9 x 13 pan lined with parchment paper and sprayed with cooking spray.
- Bake the bars for 18-20 minutes at 350°F, until lightly browned. Let cool completely. While they are cooling, prep the peanut butter and chocolate swirl topping.
Peanut Butter and Chocolate Swirl Topping
- Microwave 1 cup of creamy peanut butter in 20-30 second intervals, stirring in between intervals, until warm and pourable. Set aside while preparing the chocolate swirl portion of the topping.1 cup creamy peanut butter
- Microwave the chocolate chips and other 1/4 cup of peanut butter together in a separate bowl in 20-30 second intervals, stirring in between intervals, until smooth and pourable.¾ cup semi-sweet chocolate chips, ¼ cup creamy peanut butter
- Once the oat bars are completely cool, pour the warmed peanut butter that you had set aside over the bars. Immediately dollop the chocolate/peanut butter mixture on top of the peanut butter. Gently swirl the two mixtures to create a marbled top with a butter knife or kitchen skewer. Refrigerate the bars for 1-2 hours to set the topping before cutting into the bars- then enjoy!
Notes from the Happy To Be Here Kitchen
Note 1. Salt: I use salted butter in this recipe. If you use unsalted butter, I would add 1 1/2 teaspoons of salt to the oat bars instead of only 1 teaspoon.
