Why You'll Love This Recipe
These bars are the perfect balance of chewy and crunchy, thanks to the oats and peanut butter. They offer a rich, nutty flavor with a satisfying texture that makes them a great treat any time of day. Plus, they’re easy to make and great for sharing.
Step 1
Gently heat your oven to 400°F (200°C) and greasing a 9x13-inch baking pan. In a bowl, mix together the brown sugar, butter, corn syrup, 1/4 cup of peanut butter, and vanilla extract until everything is combined. Gradually stir in the oats until they’re fully coated. Press this mixture evenly into your prepared pan.
Step 2
Pop it in the oven and bake for about 12 to 14 minutes, or until the bars turn a nice golden brown. When they’re done, let them sit for about 4 minutes to cool slightly.
Step 3
While the bars are still warm, melt the chocolate chips, butterscotch chips, and the remaining 1/3 cup of peanut butter together. I like to do this in the microwave in 15-second bursts, stirring in between until smooth and well blended. Spread this gooey topping over the bars.
Step 4
Let everything cool completely for a couple of hours before slicing so the topping sets up nicely. Enjoy!
