Blueberry-Walnut Baked Oat Bars with Orange Zest

These bars bake up chewy and lightly golden, studded throughout with juicy blueberries and toasted walnuts. A little fresh orange zest stirred into the batter brightens the whole thing without needing any extra sugar.

Blueberries are one of the most-studied antioxidant-rich fruits, prized for their deep color and plant polyphenols, and walnuts add omega-3 fats alongside their own vitamin E — both part of the broader group of nutrients often mentioned in the context of skin-friendly, anti-aging eating. Oats round things out with fiber that helps keep this a genuinely filling snack rather than an empty-calorie treat.

Bake a batch on the weekend and keep them wrapped individually in the fridge for an easy breakfast or afternoon snack through the week.
