FAQs
Can I make Chocolate Chip Cookie Bars ahead of time?
Yes—bake, cool, and refrigerate up to 3 days or freeze up to 2 months. Warm 5 min in a 350 °F oven for fresh texture.
What’s the best substitute for butter?
Use ¾ cup neutral oil or 1 cup vegan butter. Coconut oil adds faint coconut flavor.
How do I store leftovers?
Keep bars in an airtight container at room temp 3 days, fridge 1 week, or freeze 2 months.
Why did my bars turn out dry?
Over-baking is the culprit; remove when center still jiggles slightly and top is just golden.
