Instructions

Melt Butter and Mix Sugar and Vanilla: In a saucepan over medium heat, melt the unsalted butter. Once melted, stir in the packed brown sugar and vanilla extract until the sugar is fully dissolved, creating a smooth syrup.
Combine Oats: Add the quick oats to the saucepan and cook the mixture for 2 to 3 minutes, stirring continuously to ensure all oats are nicely coated with the butter and sugar mixture.
Prepare the Base Layer: Line an 8×8-inch baking dish with parchment paper. Spread half of the oat mixture evenly across the bottom of the dish, pressing lightly to form a solid base.
Melt Chocolate and Peanut Butter: In a microwave-safe bowl, melt the semisweet chocolate chips together with the peanut butter until smooth and well combined. This usually takes 30-60 seconds, stirring halfway through to ensure an even melt.
Assemble the Bars: Pour and spread the melted chocolate and peanut butter mixture evenly over the oat base layer in the dish.
Add Top Oat Layer and Chill: Spread the remaining half of the oat mixture evenly on top of the chocolate layer, gently patting it down to create a uniform top layer. Refrigerate the bars for at least 2 hours to set completely before slicing and serving.

Notes

Use quick oats for the best texture; old-fashioned oats may make the bars too chewy or dense.
Peanut butter can be substituted with any nut or seed butter if desired.
To speed up chilling, place the bars in the freezer for about 45 minutes.
Store the bars in an airtight container in the refrigerator for up to one week.
For a nut-free version, omit peanut butter and increase chocolate chips or substitute with sunflower seed butter.
