Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish or line it with parchment paper.
In a medium saucepan over low heat, melt the butter. Add the brown sugar and corn syrup, stirring until the sugar is dissolved and the mixture is smooth. Remove from heat and stir in the vanilla extract.
In a large bowl, combine the melted butter mixture with the quick-cooking oats. Mix well until all the oats are evenly coated.
Press the oat mixture firmly and evenly into the prepared baking dish.
Bake in the preheated oven for 18–20 minutes, or until the edges are lightly golden but the center remains slightly soft. Do not overbake.
Remove the baking dish from the oven and allow it to cool slightly, about 15–20 minutes.
In a small microwave-safe bowl, combine the chocolate chips and peanut butter. Microwave in 20-second intervals, stirring after each interval, until the mixture is smooth and melted.
Spread the chocolate-peanut butter mixture evenly over the oat base, smoothing it with a spatula.
Allow the bars to cool completely at room temperature, or refrigerate them for faster setting.
Once the topping is set, cut the bars into 16 squares or desired serving sizes. Serve and enjoy!
