Caramel Filled Oat Bars with Chocolate and Walnuts

Rich oat bars layered with gooey caramel filling, dark chocolate chips, and toasted walnuts. The buttery oat base provides a tender crumb that complements the sweet caramel center, while coconut adds subtle tropical notes. Perfect for potlucks, bake sales, or afternoon treats when you want something more indulgent than cookies but easier than cake. These bars slice cleanly when completely cooled and offer satisfying textures in every bite.

FAQ
Can I use quick oats instead of old-fashioned?
Old-fashioned oats provide better texture and structure. Quick oats will work but may result in a softer, less defined texture.
How do I know when the caramel is properly melted?
The caramel should be completely smooth with no lumps remaining. Stir frequently to prevent overheating which can cause burning.
Can I freeze these bars?
Yes, freeze cut bars wrapped individually for up to 3 months. Thaw at room temperature before serving.
